But if you still need our help, then fill up our Android issues questionnaire and hit submit to contact us.

First solution: Quit the Phone app then restart your device.

If this is the first time you encounter problems in making or receiving phone calls on your Galaxy A8 2018 smartphone, then it’s likely a random glitch affecting the phone app. If that is so, you can try forcing the phone app to close and then restart your phone. Doing so will clear the app and phone system from any minor errors and glitches that might have halted the phone’s calling functions from working as intended. Here’s what you should do then:

Launch the Recent Apps menu on your phone. A list of recently used apps will then show up.
Find Phone from the app then swipe up to close.
Do the same to the rest of the background apps.

After quitting the Phone app and any background applications, restart your device to clear the phone system and refresh the internal memory for smoother and better performance. Here’s how:

Press the Power button until the menu appears and then tap the option to Power Off. After 30 seconds, you can press the Power button again until the device restarts.
Alternatively, you can just press and hold the Power button and the Volume Down button on the side until the phone restarts.

Restarting the phone (soft reset) does not affect any data stored on the internal memory, hence won’t result to data loss.

Second solution: Wipe cache and data on your phone’s system partition.

Temporary files and data that are saved as cache in the phone’s system folders can also cause pertinent issues especially when they get corrupted. This is why it’s recommended to clear cache and data regularly. If you haven’t yet done it, then follow these steps to wipe cache and data from your Galaxy A8 2018’s system partition:

With your device powered off, press and hold the Volume Up and Power buttons simultaneously for a few seconds.
Release the buttons when the Android bot image appears and the phone loads in Android Recovery mode.
Press the Volume Down button several times to scroll to and highlight Wipe Cache Partition from the given options then press the Power button to confirm selection.
Wait until the phone has finished wiping cache from the system partition. You will then see the Reboot system now option highlighted.
To restart your device, press the Power button.

Wait until the phone has finished restarting and then try to make a test call to see if it now goes through.

Third solution: Manage network settings.

Sometimes, the problem is due to invalid network settings and options selected. This is likely the case if you happened to modify something on your device incorrectly and that might have adversely affected the phone’s calling functions and relevant services. To rule this out, you can reset network settings on your Galaxy A8 2018 smartphone to restore the default network settings and values. This however will delete your Wi-Fi networks, Bluetooth and server settings on your device, so you’ll need to set them up again afterwards. Here’s how it’s done:

Tap Settings from the Main Menu.
Scroll to and tap General Management.
Tap Reset.
Select Reset Network Settings from the given options.
Read the information and then tap the Reset Network Settings button to continue.
Then tap Reset settings to confirm action.

After the network settings reset, reboot your phone to apply the changes and clear any glitches from the phone system. Then do a test call to see if it is already working as expected.

Fourth solution: Update your device software to the latest version available.

Software updates not only offer new features and enhanced functions but also contain fix patches to address existing device issues that are attributed to software bugs and malware. If bugs and malware are halting your phone from processing phone calls, then installing a new software update will likely fix it. To check for software (Android) update available for your device, follow these steps:

Go to Settings.
Tap About device.
Tap Software update.
Tap Update now or Download updates manually.

Before you download and install any update, back up your data for safekeeping. This is to ensure you won’t lose any personal information in the process. Also make sure that your phone is connected to Wi-Fi Internet and has enough power and memory space to continue with the update.

Fifth solution: Remove and reseat the SIM card on your phone.

Removing the SIM card can also help when dealing with problems on network-related services. It’s another way of restarting the phone’s network functions and likewise, ensuring that everything is good with the SIM card and the SIM card tray. SIM card issues like damaged cards or card tray are also among the possible reasons as to why calling functions aren’t working on the phone, so make sure you have that one checked as well. Here’s how it’s done:

Turn off your phone completely.
Insert the ejection pin into the tiny hole to loosen the tray.
Gently pull out the tray from the slot.
Remove the SIM card from the tray.
Examine the SIM card and tray for any signs of damage like scratches or dents. If everything looks good, then place the SIM card back on the tray with the gold contacts facing downwards.
Gently press the SIM card to the tray to secure it.
Insert the tray back into the tray slot. Be sure to fully insert the tray back into the tray slot to prevent the liquid from enter the device.

When everything is secured in place, turn on your phone and then try to do a test call to see if the problem is resolved.

Other options

If you still cannot make or receive phone calls on your Samsung Galaxy A8 2018 smartphone after exhausting all possible solutions on your end, contact your network service provider or carrier to report the issue for further assistance and recommendations. Also verify that your account and service status are good. Sometimes the problem could be tied to account issues that need to be settled. You can also ask them to check their outage board for any ongoing outage that might have affected network-related services in your place.

Alternatively, you can take your device to a Samsung service center nearby and have it examined by an authorized technician for any indications of physical or liquid damage. Doing so will help rule hardware damage out from the underlying causes.

Samsung Galaxy Note 5 can’t make / receive calls, other call related problems

To be able to make and receive phone calls are among the most common features a mobile phone has.

So, in this post, I have addressed three of the most common call-related problems. If you own a Note 5 and are currently bugged by a problem or two, then continue reading as this post may be able to help. Go through the short list below to see if your problem is included. Just click on the link to jump to a specific issue.

Galaxy Note 5 cannot make a phone call

Find issues that are similar with yours and use the solutions we provided. If they don’t work or if you need further assistance, you may contact us by completing our Android issues questionnaire.

Galaxy Note 5 cannot make a phone call

Problem: It just started. My Samsung Galaxy Note 5 can no longer make a phone call. When I dial a number, the call won’t go through. I’ve already power-cycled the phone a million times but it’s still the same. Called tech support, they too don’t know what’s the problem is. So, if you guys can help me figure this out, that would be great! Thanks.

Troubleshooting: Regardless of the brand and model of the phone, it must be connected to the provider’s cellular network to be able to receive all the services being offered. That being said, the first thing you must do is to make sure it is properly connected to the network and that it gets decent connection without any bars on your account. To make it easier for you, here’s the outline of what you need to do:

Step 1: Call your provider’s tech support

This is a very simple task to do and it’s probably the best way to determine if the problem is with your phone or network-related. The rep should be able to determine right away if there’s a problem with your area or if there’s a certain problem with the tower where you get service from. In which case, only your provider can help you determine the problem and provide a solution, however, if the problem is with your phone, they you should continue troubleshooting. So that you can easily remember things you must inquire about, here’s a short list:

Ask if there’s an ongoing outage in your area
Inquire if there’s a network problem like service interruption in your area
Ask if there’s a problem in the tower your phone is connected to
Ask if there’s a problem with your account. Account verification may be necessary.
Verify that your phone is properly provisioned and setup properly

Step 2: Perform Master Reset on your Note 5

After calling tech support and the rep told you everything looks good on their end, then don’t waste your time with other things. Instead, backup your data and files and then do the master reset. This will bring the phone back to its default settings:

Remove your Google account and disengage the screen locks to make sure you won’t trip the Factory Reset Protection (FRP).
Turn off your Samsung Galaxy Note 5.
Press and hold the Volume Up, Home and Power keys together.
When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
Wait until the Android Recovery Screen appears after about 30 seconds.
Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

After the reset and the problem persists, bring the phone to the store and have it checked.

Calls to Galaxy Note 5 go straight to Voicemail

Problem: I can make outgoing phone calls but when my friends or family call me, their calls will be sent directly to Voicemail but on my end, I couldn’t hear the phone ring and there’s nothing on the Missed Calls log. I want to fix the problem I don’t know where to begin. I hope you can help, thank you!

Solution: This problem can happen if there are some corrupt caches and data on your phone. If it occurred shortly after an update, it might be the cache, so try to wipe the cache partition first.

Turn off your Galaxy Note 5.
Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
When the Android System Recovery screen appears, release the Volume Up and Home keys.
Press the Volume Down key to highlight ‘wipe cache partition.’
Press the Power key to select.
When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
Press the Power key to restart the device.

If the wiping of the cache partition won’t bring about good results, then reset your phone. Try the typical factory reset first and then the master reset if it fails but make sure you backup your files and data first as they’ll be deleted.

From the Home screen, tap the Apps icon.
Find and tap the Settings icon.
Under the ‘Personal’ section, find and tap Backup and reset.
Tap Factory data reset.
Touch Reset device to proceed with the reset.
Depending on the security lock you used, enter the PIN or password.
Tap Continue.
Touch Delete all to confirm your action.

Should the problem continue after the reset, then call tech support. During my tenure as a tech support representative for one of the wireless companies in the U.S., I always get this kind of problem. We had a tool that could fix it in one click. Thus, if the problem isn’t fixed by doing the basic troubleshooting, let tech support fix it for you.

Galaxy Note 5 doesn’t have an option to view caller ID

Problem: There is not an option to change or view caller ID in “More Settings” on Note 5, although all the instructions I’ve followed have said that is where you can change it-Phone , Settings ,More Settings-no caller ID anything. However I have read numerous complaints of same nature from other Note 5 owners. If hiding caller ID is not an option on Note 5 you should remove the instructions you post to accomplish it.
Troubleshooting: Identifying callers is very important especially if your phone number is exclusive for business purposes only. Waiting for a call from a friend or family as well, is one of the common reasons why “Caller Identification” has been included in phone features. In general, Caller ID lets your friends, family and business associates let you know that they are calling you and vice versa. But how will you enjoy this phone feature especially in your awesome Samsung Galaxy Note 5 if you can’t simply have it set up? There is nothing to worry because we are here to keep you at ease. Below are the things that you have to do to view or change caller ID feature.
Now, if ever this method will not work after you follow the steps below, we recommend that calling your network provider is the best option, other network providers won’t allow “hide caller ID”. Only your network provider can tell what the reason behind it.

From your Home Screen, tap Apps.
Go to Contacts.
From the drop down list on Menu, tap Settings.
Tap Call.
Select More Settings.
A pop up will appear. Tap Caller ID.
From that, Caller ID options will be given.
Tap on your preferred Caller ID setting.

Network Default – This uses your Network Default settings. This service is provided by your Network Operator.
Hide Number – This feature allows you to hide your number in outgoing calls.
Show Number – Feature that will show your number in outgoing calls. Note: If your Caller ID is not showing, you have to make sure that your SIM card is in the device. Caller ID feature is automatically disabled if the device cannot detect a SIM number.

We hope that after following the steps above, your problem on Caller ID feature will be solved because your safety away from nuisance callers are our concern.

How to fix a Samsung Galaxy J2 Pro that cannot make or receive phone calls (easy steps)

Calling problems can be inflicted by many different factors from network problems, account issues, invalid settings, faulty updates, SIM card issues, and worst, hardware damage on the phone. This denotes the need for you to look into each of these factors whenever you will have some trouble making or receiving phone calls on your device. Tackled in this post is the same issue transpiring on the new Samsung Galaxy J2 Pro (2018) smartphone. Read further if you need more inputs on how to deal with this issue.

How to troubleshoot Galaxy J2 Pro 2018 that can’t make / receive calls

Before you troubleshoot software problems on your device that might have prevented you from making or receiving phone calls, check and ensure that your phone is getting a good signal. If the signal indicator is showing 1 to 2 bars and that it’s stable, then you’re good. Otherwise, you will need to deal with network problems first for calling functions to resume on your device. If the signal is good but you still cannot make or receive phone calls on your Samsung Galaxy J2 Pro (2018) smartphone, then move on and start troubleshooting with these subsequent workarounds.

First solution: Perform a soft reset/restart.

A soft reset or device restart will likely fix the problem if it’s just occurring among other random issues on the phone. This clears any minor system errors that might have caused the Phone app to glitch and fail to work as intended. Here’s how a soft reset is done on your Galaxy J2 Pro 2018:

Press the Power button for a few seconds until the menu options show up on the screen.
Tap to select Power off option.
Then tap OK to confirm.
Wait for about 30 seconds then press the Power button again to turn your phone back on.
Alternatively, you can do a force restart by pressing and holding on the Power button and Volume Down button simultaneously for about 10 to 20 seconds and then release the buttons when the phone restarts.

Both these methods will not delete any data from the internal memory of your device, thus won’t require you to create backups.

RELEVANT POSTS:

Second solution: Clear cache and data from the Phone app then retry calling.

Cache files stored in the Phone’s memory might be to blame especially when any of them gets corrupted. To rule this out, try to clear cache and data from the Phone app with these steps:

Tap Apps from the Home screen.
Navigate to Settings-> Apps menu or Settings-> Apps & Notifications-> App info, for devices running on Android Oreo platform.
Tap to select Phone app.
Tap Storage.
Tap Clear Cache. This will wipe cached files from the Phone app.

Wait until the cache is completely cleared and then restart your device.

Third solution: Reset network settings/Reset all settings.

Invalid settings particularly options that are associated with the network functions of the phone can also be the main reason as to why you cannot make or receive phone calls. These settings can be altered manually or automatically. Some software updates might have automatically override your phone settings and may result to this problem. To rule this out, you can reset network settings and all settings on your phone to restore the default values and then reconfigure necessary options accordingly. Here’s how:

Tap to open the Apps screen.
Scroll to and tap Settings.
Select General management.
Tap Reset.
Select Reset Network Settings. This will reset network connectivity options and settings back to their default values.
To reset system settings back to the original configuration without deleting any data and personal information, select Reset Settings instead.
Read the information and select Reset Settings twice to confirm action.

Reboot your phone afterwards to apply the new changes and refresh the phone system. Then do a test call to see if it’s already working.

Fourth solution: Remove and reinstall the SIM card.

If you see any error message pertaining to the SIM card like invalid SIM card, No SIM card detected, SIM card not recognized, and the like, try to remove and reseat the SIM card. It’s possible that the SIM card is loose or dislodged, thus your device cannot read it. Cellular services should be back up and running once the SIM card is fixed. So here’s what you should do then:

Turn off your phone completely.
Gently pull out the SIM card holder.
Remove the SIM card from the tray.
Examine the card and tray for any visible signs of damage.
If everything looks good, place the SIM card back into the tray in the same orientation before you remove it.
Push the SIM card tray back into the slot.

When the tray is locked and secure, turn on your phone and then attempt to make a test call to find out if you can now make and receive phone calls on your device.

Fifth solution: Perform a factory data reset/master reset.

A factory data reset or master reset can be considered as last resort if the problem persists after performing all the above procedures and other applicable workarounds. There might be some complex system errors or tough bugs that might have prevented your device from processing calls. In this case, a full system reset would be necessary. Be reminded though that this will delete all data and personal information you’ve stored on the internal memory of your phone and restores all settings to factory defaults. Should you wish to proceed, back up all your important files and then follow these steps to carry out a master reset on your Galaxy J2 Pro 2018 smartphone:

Open the Apps menu.
Tap Settings.
Scroll to and tap General management.
Tap Reset.
Select Factory data reset from the given options.
Read and review the message then tap Reset.
Tap Delete All to confirm system reset.

Wait until the reset is finished and your phone reboots automatically. You can proceed with the initial setup process afterwards.

How to fix a Huawei Mate 10 Pro smartphone that cannot make or receive phone calls [Troubleshooting Guide]

There are a lot of factors that you need to consider looking into when dealing with calling issues on your smartphone. From your account status to network status, settings, apps, contacts, and even the SIM card in use. All these along with other attributes are to be regarded among the underlying causes.

The first thing you should check whenever you’ll bump into an issue in which your device cannot make or receive phone calls is the network status of your phone. Does your phone have stable or strong network coverage (signal)?

To find out, check the signal bars or indicators on your phone. If it shows at least a single bar but stable, then you’re good. Otherwise, you’ll need to find other ways to make your phone obtain good signal from your network. If the signal is good and yet you still cannot make or receive phone calls, check your account and network service status. This means contacting your network service provider or carrier.

For other possible solutions and troubleshooting methods to try when dealing with similar issues on a Huawei Mate 10 Pro smartphone, I’ve mapped out a few potential solutions for you to try on. Read further for more details.

But before anything else, if you have another issue with your phone, drop by our troubleshooting page as we have already addressed hundreds of issues reported by the owners. Odds are that there are already existing solutions on our website or at least, there are similar problems we already fixed. So, try to find ones that are similar or related to your problem. If you need further assistance, however, feel free to contact us by filling up our Android issues questionnaire.

First solution: Restart your phone (soft reset).

Should the problem be triggered by random software glitches or application errors, performing a soft reset or restarting the phone will likely fix it. A device restart also dumps cached files including corrupted data from the internal memory and therefore resolves any associated issues. If you haven’t already, soft reset or restart your Huawei Mate 10 Pro with these steps:

Press the Power button for a few seconds or until the menu options appear.
Select Power off option and then tap OK. Doing so will shut down your phone.
After 30 seconds, press the Power button again until your device restarts.

A soft reset does not affect any data stored on the internal memory of the phone, thus all your personal files will remain intact afterwards.

Second solution: Boot your phone in safe mode.

Safe mode is where you can diagnose apps easily and determine whether or not the problem is triggered by a third-party app on your device. All downloaded apps are bypassed and not permitted to run in safe mode, thus only the preinstalled apps are running. Then you can try making phone calls to your own number and see if you can receive incoming calls. Here’s how to enable safe mode on your Huawei Mate 10 Pro:

Turn off your phone by pressing the Power button until it shuts down.
Then press the Power button again to turn it back on.
As soon as you see the Huawei animation screen, press and hold the Volume Down button until your phone boots up.

When it’s finished booting up, you should see Safe Mode at the bottom left corner of the screen. This means that the phone is already running in safe mode.

If your device is able to make and receive phone calls while running in safe mode, this denotes that any of your third-party apps may be interfering with the network connection of your phone. In that case, you will need to determine which app is the culprit and then remove it. It’s likely the one you’ve downloaded prior to the onset of the problem. You may need to uninstall apps individually and then test your device to see if the problem is solved.

You can also disable any installed apps on your device that may have features for blocking or rejecting phone calls.

Third solution: Toggle Flight Mode on and off.

You won’t be able to make or receive phone calls, send or receive messages or access mobile data if Flight mode is enabled on your device. To make sure this isn’t what’s halting you from making or getting phone calls, check and ensure that Flight mode is turned off. If it’s already off/disabled, try to turn it on shortly and then on again. Here’s how it’s done:

Slide your two fingers downwards from the top of the Home screen. Doing so will open the Notifications panel.
Tap the Airplane Mode icon to turn the feature on for a few seconds then tap the icon again to turn Airplane Mode off.

This trick somehow refreshes and restarts network functions on the phone and therefore resolves minor software glitches attributed to network errors.

Fourth solution: Remove and reinstall SIM card on your phone.

Make sure the SIM card is not dirty or damaged. SIM card issues like defective or damaged SIM card, may also be the main reason why you won’t be able to make and receive phone calls on your phone. To clear this out, try to remove and reinstall the SIM card on your phone with these steps:

Power off your device.
Locate the SIM slot on the left side and the insert the SIM ejection tool or a bent paper clip into the small hole.
Gently push it until the SIM tray ejects.
Remove the SIM tray carefully.
Then take the SIM card off from the card slot. Examine the card for any signs of damage like scratches. If the SIM card is dirty, clean it gently with a dry cloth. If you suspect that the SIM card is damaged, contact your service provider/carrier and then ask for a replacement SIM card instead.
If everything looks good with the SIM card, place it back into the SIM card slot with the gold contacts facing downwards.
Secure the SIM card in the slot and then push the SIM tray back into the phone.
Push the slide back on your phone and then lightly push on it until it snaps into place.

When the SIM tray is secured and locked in place, turn on your phone and then try to see if the problem is fixed and your phone is already able to make and receive phone calls.

Fifth solution: Reset network settings on your phone.

A network settings reset will wipe all your current network settings and selections then restore the default network settings on your phone. This can be the key to fixing the issue if invalid or incorrect network settings have something to do with it. To give it a try, follow these steps to reset network settings on your Huawei Mate 10 Pro:

Tap Settings from the main Apps screen.
Scroll to and tap Advanced Settings.
Scroll to and tap select Backup & Reset option.
Then select Network settings reset.
Tap Network settings reset again to confirm.

Your device will then instigate the network settings reset process and then reboots automatically when done. After the restart, you can set up and enable network services on your phone. Wait until your device re-establishes network connections and then test to see if calling functions are already working as intended.

Other options

You may continue to troubleshoot and resort to a last-ditch solution which is a master reset or factory data reset. This can help get rid of more intricate system errors that might have affected your phone’s calling functions. If you’ve tried all possible solutions but your Huawei Mate 10 Pro is still unable to make or receive phone calls, contact your service provider/carrier to see if there are any issues with your service like network issues or possible scheduled maintenance in your area.

How to troubleshoot LG G7 ThinQ that can’t make / receive phone calls

Before you begin to troubleshoot, check the signal indicator on your phone and make sure it’s getting a good signal. If you’re seeing No signal, No service, or other relevant error prompts, then that should be the main reason why you cannot make or receive phone calls on your LG G7 ThinQ smartphone. In that case, you will need to deal with network problems on your device instead. Network functions, including phone calls should be restored once you’ve fixed and dealt with network problem on your device. Otherwise, try to troubleshoot software problems on your phone that might have caused conflict. Here are some generic solutions for you to try on.

First solution: Reboot your phone (soft reset).

Minor network errors can occur at any time on any device. Thus what you’re going through may be just a random network-related issue on your phone that’s rectifiable by a reboot or soft reset. If you haven’t yet restarted your phone for quite some time now, then try doing so with these steps:

Press and hold the Power button and Volume Down button simultaneously for a few seconds and then release both buttons when the phone reboots.

Performing a soft reset likewise refresh the operating system and clears the internal memory from cache and temporary data including those that were corrupted. You don’t need to create backups because this won’t affect saved data on your device.

Second solution: Toggle Airplane mode on and off.

Turning Airplane mode on will disable data and network services on your phone automatically. Thus check and ensure that Airplane mode is turned off on your LG G7 ThinQ. If it’s already turned off but still you cannot make or receive phone calls, then try toggling the Airplane mode switch on for a few seconds and then off again. Many people have already found wonders from doing this old trick when dealing with network-related issues on their Android devices. Here’s how to turn Airplane mode on or off your LG G7 ThinQ:

Tap Settings from the Home screen.
Tap Network & Internet.
Navigate to the Airplane mode menu then tap the switch to turn the feature on. After about 30 seconds, tap the switch again to turn off Airplane Mode.

Reboot your phone one more time and then retry making a test call to see if it’s already working. If it still failed, then continue to troubleshoot software problems on your phone that may have inflicted network or calling problems.

Third solution: Test calling functions while in safe mode.

Safe mode puts your device in diagnostic state. It allows your device to turn on without third-party apps running, making it easier for you to determine whether or not the problem is due to a third-party app. Here’s how to enable safe mode on your LG G7 ThinQ smartphone:

With your phone screen on, press and hold the Power button until the menu options appear.
Press and hold the Power off option.
When you see the message prompt to Restart in Safe Mode, tap OK to confirm.
Wait until your device restarts in safe mode. You will then see the Safe Mode label at the bottom of the screen.

Try to make a test call on your own number and see if you can make and receive it while in safe mode. If your phone is able to make and receive phone calls while in safe mode, then you will need to remove the errant application. Try to think of which apps you’ve downloaded recently is causing conflict or preventing your device from carrying out calling functions. It’s likely the one you’ve installed prior to the onset of the problem. You may have to delete or uninstall individual apps, if necessary.

If you still cannot make or receive phone calls while in safe mode, then you’re likely dealing with a more complex software issue that requires more advanced solutions, including system resets. It’s also possible that your phone is obtaining some sort of physical or liquid damage on the network components thus no longer able to carry out calling functions. In that case, service would be necessary.

Fourth solution: Reset network settings on your phone.

Resetting the network settings on your LG G7 ThinQ may help if the problem is due to network errors on the phone. This reset will clear your current network settings and restore the default values. Any erratic settings will be deleted. Cellular and Wi-Fi network settings including saved networks and passwords as well as Bluetooth connections are also deleted in the process, which means you will need to set them up again after the reset. Whenever you’re all set, follow these steps to reset network settings on your LG G7 ThinQ smartphone:

Tap Settings from the Home screen.
Tap System.
Tap Restart & reset.
Select Network settings reset from the given options.
Tap RESET SETTINGS to continue.
Then tap Reset Settings again to confirm reset.

Allow your device to instigate the network settings reset and then restarts when done. As soon as it’s done restarting, set up Bluetooth connections and re-connect to your Wi-Fi networks.

Network-related issues should be all gone by then.

Fifth solution: Remove and reinstall your SIM card.

Calling problems may also be due to a bad SIM card. Your SIM card may be dislodged and needs to be reseated. To check and ensure that the problem isn’t on the SIM card, follow these steps to remove and reseat the SIM card on your LG G7 ThinQ smartphone:

Turn off your device completely.
Get the insertion/removal tool then insert it into the provided slot on the tray.
When the tray ejects, gently pull it out.
Remove the SIM card from the tray. Carefully lift from the bottom of the card to remove it.
Examine the card for any visible signs of damage. If it looks okay, place it back into the card tray, with the gold contacts facing down.
Insert the card tray.
Press in on the tray until it’s locked into place.

When the tray is locked and secured in place, turn on your phone and then try to make a test call to see if it’s already working as intended.

Other options

If you still cannot make or receive phone calls on your LG G7 ThinQ smartphone after performing all applicable workarounds, then you can report the problem to your network service provider or carrier for further assistance and recommendations. You can ask them to check their outage boards to ensure that the problem isn’t due to an ongoing outage or network maintenance. Also check your account status and make sure it’s in good standing. If necessary, settle any account issues with your carrier to ensure all your outgoing services are active.

If you suspect that a faulty hardware is causing this trouble, then you can take your device to an LG authorized service center nearby and have it diagnosed by an authorized technician. Don’t forget to avail for warranty if your phone is still covered.

We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

How to fix your Galaxy S9 Plus that can’t make / receive phone calls

Before you troubleshoot software problems on your Samsung S9 Plus that might have caused you such a problem in making or receiving phone calls, consider these few suggestions:

If you cannot receive phone calls only from one specific contact, check your auto-reject list and make sure that the contact number you’re having trouble with is not in the list.
Power off your phone and then remove the SIM card. Carefully check the SIM card to see if there are any visible signs of damage like scratches. If the SIM card is damaged, then you will need a replacement SIM card. Contact your carrier for that matter.

If the problem continues after you’ve done the aforementioned suggestions, then continue to troubleshoot the problem with the following solutions. Don’t forget to do a test call after completing each method to find out whether or not the problem is fixed. Proceed to the next applicable solution if needed.

First solution: Reboot your phone.

Minor software glitches and errors can easily be dealt with by a device restart or soft reset. It’s been the simplest and most effective solutions to random software issues among various types of electronic devices including smartphones. So if you haven’t already, follow these steps to soft reset or reboot your Samsung S9 Plus:

Press and hold the Power button.
Tap the option to Power off.
Tap Power off again to confirm.
After about 30 seconds, press and hold the Power button again until your phone boots up.

This does not affect any of your phone data so there’s no need to create a backup beforehand.

Second solution: Boot into safe mode and do some test calls.

To rule third-party apps from the possible culprits, try booting your phone into safe mode and do some test calls. Al third-party apps and services are bypassed or temporarily disabled in this mode, thus it would be easier for you to determine if it’s due to a third-party app or not. Here’s how to enable safe mode on your Samsung S9 Plus:

Turn off your phone.
Press and hold the Power button past the model name screen.
Then release the Power button when the Samsung logo appears.
Immediately after you release the Power button, press and hold the Volume Down button.
Keep holding the Volume Down button until the phone completes the restart.
When it boots up, a Safe Mode badge should appear at the bottom left corner of the screen. At this point, you can release the Volume Down button already.

Do some test calls while your phone is running on safe mode and see if you can make and receive calls. If your phone is able to make and receive phone calls in Safe mode, it denotes that there may be some third party apps interfering with the network functions or connection of your phone. In that case, you will need to deal with apps problem. Try to think of which app you’ve downloaded recently as it’s likely causing you this trouble. You have to uninstall the bad app so as to fix calling issues on your Samsung S9 Plus. Or you can also try to disable any apps you have installed on your phone that may have features for blocking or rejecting calls.

Third solution: Remove/uninstall bad apps.

If your phone is able to make and receive phone calls in safe mode, then it denotes that the problem is caused by a third-party app. In this case, you can uninstall any suspicious apps, probably the recent apps you’ve downloaded on your phone. Here’s how:

Swipe up on an empty space from the Home screen to open the Apps tray.
Tap Settings.
Then tap Apps.
Select the app you want to uninstall.
Tap Uninstall.
Then tap OK to confirm action.

Reboot your device after making these changes then try to do some test calls to see if that fixes the problem. If not, then move on to the next solution.

Fourth solution: Reset network settings.

Invalid network configurations or incorrect network options are likewise among the possible reasons as to why you won’t be able to make or receive phone calls. If you just made some changes to your network settings and then suddenly you bump into this problem, then most probably you’ve configured your network settings wrongly. Try reverting the changes you’ve made back to the previous configuration and then see if that fixes the problem. But if you cannot figure out which options or values to change, then just go for a network settings reset instead. Here’s how:

Swipe up on an empty spot from the Home screen to open the Apps tray.
Tap Settings.
Tap General Management.
Scroll to and tap Reset.
Select the option to Reset network settings. This will erase all your current network settings and restores the default values.
Tap Reset Settings.
If prompted, enter your device PIN or password.
Tap Reset Settings again to confirm action.

Your phone reboots automatically when the reset is finished so wait until it boots up completely then set up your networks including Wi-Fi and cellular data to use network services on your device as you normally do.

Fifth solution: Backup and reset your Samsung S9 Plus.

Your last option if all else failed to fix the problem is a factory data reset. This can be the key to fixing the problem especially if it’s due to some complex bugs or major system errors that can only be rectified by a full system reset. However, you will lose data and personal information in the process. If you think it’s worth a shot, then back up all your important data then go for a full system reset with the following steps:

Swipe up on an empty spot from the Home screen to open the Apps screen.
Tap Settings.
Tap General management.
Tap Reset.
Select the Factory data reset option.
Scroll to the bottom of the screen then tap Reset.
Select the option to DELETE ALL.
If prompted, enter your credentials for screen lock and Samsung account verification.
Tap Confirm to continue.
Wait for the reset to finish and your device to reboot.

Alternatively, you can perform a factory data reset on your Samsung S9 Plus via Android recovery mode. If necessary, you can refer to a more comprehensive walkthrough on how to reset and restore your Samsung S9 Plus in recovery mode from our Tutorials page.

Ask further assistance

You can always reach out to your carrier and escalate the problem if you’ve already exhausted all possible means to fix it on your end but to no avail. There might be some other reasons why your Samsung Galaxy S9 Plus is still unable to make or receive phone calls up to this point. Verify and ensure that it has nothing to do with account-related issues or network issues like ongoing outages that might have caused relevant services to become unavailable momentarily. Meanwhile if you started to have trouble making or receiving phone calls after updating your Samsung S9 Plus software, then most likely it’s a post-update bug that would require a fix patch. In this case, you may opt to contact Samsung Support for official recommendations.

How to fix your Samsung Galaxy Note 8 that cannot make or receive phone calls (easy steps)

Problems on making or receiving phone calls are among the most prevalent issues transpiring in different types of smartphones from basic to mid-range and even with the highest-tiered smartphones to-date. Many factors can trigger these problems to occur. Oftentimes, network errors are to blame. Other possible culprits are account issues, invalid settings, bugs and software glitches on the device itself. For calling issues that are related to account problems, you will need to contact your service provider or carrier to settle whatever there is that needs to be settled in your account for your services to resume. For other factors that are associated with the phone system like incorrect settings, system bugs and firmware glitches, troubleshooting would be necessary.

If you happen to deal with the same issue on your Samsung Galaxy Note 8 that cannot make or receive phone calls for some reasons, then this post might be able to help you out. I have mapped out a few simple solutions and recommended workarounds you can refer to whenever you’re set to troubleshoot software problems on your Note 8 that might have caused you these errors.

For smartphone owners who found our site while trying to find a solution, try to see if your phone is one of the devices we support. If it is, then visit the troubleshooting page for that device, browse through it to find issues that are similar with yours and feel free to use our solutions and workarounds. However, if you still need our help after that, then fill up our Android issues questionnaire and hit submit to contact us.

How to troubleshoot Galaxy Note 8 that can’t make / receive phone calls

Before you start troubleshooting, make sure that your phone is getting a good signal. If your phone has no service or shows no signal bars, then you will need to deal with signal issues first. You should have at least 2 bars to be able to make or receive calls on your phone. If the signal is strong but you still cannot make or receive phone calls, then continue and try these workarounds.

First solution: Reboot your phone (soft reset).

Performing a soft reset can help wipe out minor glitches that might have interfered with your phone’s calling functions. This won’t affect any of your data stored on the internal memory of your phone so you don’t have to create backups. If you haven’t already, then here’s how a soft reset is done on your Galaxy Note 8:

Press and hold the Power button until the Power Off prompt appears.
Tap the option to Restart.
Tap Restart again to confirm.

Give your phone at least 90 seconds to complete the restart and then try to make a call to see if it is already working as intended.

RELEVANT POSTS:

Second solution: Remove and reseat the SIM card.

Calling issues in mobile devices are usually attributed to network errors, either on your service provider’s end or on your device itself. If you happen to see any error prompts including SIM card errors, then reseating the SIM card can help. It’s also a way to refresh the SIM functions on your device. If you wish to try it, then here’s how it’s done:

Insert the ejection pin into the tiny hole on the tray to loosen it. Make sure that the ejection pin is perpendicular to the hole to prevent causing damage to your device.
When you hear a slight click, it means that the tray has popped out.
Gently pull out the tray from the slot.
Remove the SIM or USIM card from the tray.
Check the SIM card for any signs of damage. If everything looks good to you, then place it back into the tray in the same way when you took it.
Insert the tray back into the tray slot. Make sure it’s fully inserted into the slot to prevent liquid from entering the device.

When everything is secured in place, turn your phone on and then do some test calls.

Third solution: Clear cache and data on Phone/Dialer app.

Cached files are helpful when it comes to fast reloading of similar information. However, these files can also get corrupted at some point and when that happens, there is a higher chance that your phone’s system functions are affected. Cache can be found in individual apps while others in the system cache partition of your phone. To make sure that issue is not tied to corrupted cache, try to clear cache on your Phone app first. Here’s how:

Swipe up on an empty spot from the Home screen to open the Apps tray.
Tap Settings then select Apps.
Tap the Phone app.
Go to Storage.
Tap the option to Clear Data then tap OK. Selecting this option will delete any stored data in the app including settings and other saved information thus it’s optional.
Tap Clear Cache. This option clears temporary files or cache files from the Phone app.

Restart your device when you’re done and then try to do some test calls to see if they’re working now.

Fourth solution: Reset network settings on your phone.

How you configured your network settings will affect network functions of your phone. If the problem started after making some changes to your phone settings, then most likely it has something to do with it. There might be some settings or options that you’ve configured incorrectly and that should be corrected. But the thing is, identifying which settings or options to modify is a bit of a challenge. As alternative solution, you can reset your phone’s network settings instead. Here’s how:

Open the Apps tray by swiping up on an empty spot from the Home screen.
Tap Settings.
Tap General Management.
Tap Reset.
Select the option to Reset network settings.
Tap Reset settings.
When prompted, enter your device credentials like PIN or password.
Tap Reset settings again to confirm.

When the network settings are reset, your phone will reboot automatically. If not, then you will need to manually trigger your phone to restart. After it boots up completely, set up your Wi-Fi networks and other necessary features to use them again on your phone. See if that fixed the problem.

Fifth solution: Update your phone software to the latest version available.

Software updates usually contain security enhancements or fix patches to get rid of any bugs that might have caused certain issues to occur on a device. If your Phone app is affected by certain bugs, then failure to make or receive calls can be the transpiring symptom. Should this be the case, installing the latest software update on your device will likely be able to deal with it. Here’s how to get started:

Open the Apps tray.
Tap Settings.
Tap Software update.
Select the option to Download updates manually.
Tap OK.
Tap Start.
If prompted with a restart message, tap OK to instigate device reboot or soft reset. Doing so will apply the new changes from the recently installed update on your device.

When your phone has booted up, open the Phone/dialer app and do some test calls to see if you’re now able to make and receive phone calls on your device.

Other options

Master reset. You may resort to performing a factory data reset or master reset if your Samsung Galaxy Note 8 is still unable to make or receive phone calls after exhausting all prior methods. There might be a more complex system issue that requires tougher solutions. But please note though that this reset will wipe everything from your phone including your critical data, personal information and other contents. Should you wish to proceed, don’t forget to back up all your important data.
Technical support. If nothing works and you already run out of options, then you can seek further assistance from your carrier or network service provider’s technical support people. Give them a call and report the problem for other options and recommendations. Also care to check and ensure that your account status is good and that there are no network outages or ongoing technical issues that might have caused network service disruption in your place.
Contact Samsung Support. If the problem started after installing a new software update, then most likely it’s a post update issue that usually needs a fix patch. In this case, you may contact Samsung Support for them to further assess if the problem you’re dealing with is indeed a post-update issue or not.

What seems to be the problem if callers cannot hear you during calls you can hear them well?

To be able to make and receive phone calls are among the most common purpose of a phone. Such service can easily be done by basic phones whose purpose is to send/receive text messages and calls. Smartphones like your Samsung Galaxy S7 should be able to do it, too, without a hitch but it seems like many of the owners are complaining that many of their phone calls–regardless whether they’re the ones making or receiving them–keep on dropping and there are also times when they just can’t dial a number to call.

We have received a lot of complaints from our readers that’s why we need to address this problem especially that many are expecting us to help them troubleshoot their phones. Below are the troubleshooting steps you need to do in order to fix it. However, there’s no guarantee that your phone will be fixed especially if the issue is related to a faulty hardware or component.

At the later part of this post, I cited some of the issues we received from our readers and addressed them one by one. Read on to learn more about them as you may encounter one of them in the future.

For those who have other issues, you may visit our S7 troubleshooting page and find issues that are similar or related to yours. Use the solutions and/or troubleshooting guides we provided. If they don’t work or if you need more help, then feel free to contact us by completing our Android problems questionnaire. Make sure you provide us with more information so we can give you more accurate solutions.

Possible Causes

A temporary glitch with either the firmware or hardware
A temporary network issue like an outage
The signal dropped in your area
Some settings got changed in your phone
Some cache or data got corrupted in your phone
A more serious firmware or hardware issue

Troubleshoot Galaxy S7 that can’t make/receive calls

It is always very helpful if you knew what caused the problem because you can always find a way to work around it rather than spending most of your time troubleshooting. However, more often, problems like this are minor so instead of going immediately to a shop to get it checked, we suggest you do some troubleshooting first as it might save you from driving several miles and waiting for hours at the shop. So, if your phone difficulties making and receiving phone calls, here’s what you need to do:

Step 1: Reboot your phone if you haven’t already

Do this especially if it’s the first time the problem occurred. There are times when the firmware and/or the hardware glitches and affects the performance of the device while crashing some of the native services. A reboot has always been effective in fixing minor issues.

It’s easy to do, doesn’t pose a threat to your files and data and you don’t need to have advanced knowledge. After the reboot, try to make a call to any number and see if you can, if still not, then try to call your number from a different phone to see if it rings.

If the phone rings but you can’t make a call, it’s more likely an account issue; call your provider and seek assistance.

However, if the device both won’t dial a number nor receive incoming calls, continue your troubleshooting.

Step 2: Check the signal indicator to see if the phone gets a decent reception

There are different ways to do this but the most basic is to look at the signal indicator on the status bar. You’ll know exactly if your phone is getting excellent, fair, poor or no signal at all. If your phone has a fair or excellent reception and you can neither make nor receive calls, try the other steps below.

However, if your device is showing poor or no signal at all, then that should be the reason why it can’t make/receive calls or may result to random dropped calls.

Poor signal is often caused by a network problem or may be you’re in an area where there really is a poor coverage. Your provider may be able to provide you more information about this as they often have a map that reveals the areas with poor coverage. But if this problem started recently and you actually were enjoying a good service, then it might be a firmware or a hardware issue.

On the other hand, if your phone shows it doesn’t get any signal at all, then here’s what you need to do:

Make sure Flight Mode is disabled
If it occurred for the first time, reboot your phone
If your phone suffered either liquid or physical damage, visit a technician right away
If the reception is lost after an update, try doing the next steps

Step 4: Try wiping the cache partition if the problem occurred after a firmware update

System caches get corrupt more often especially after major updates and while the Galaxy S7 hasn’t received any major updates yet, there have already been a few security updates that were rolled since its release. So, if your device got updated recently and then the signal got lost, you should try wiping the cache partition first.

The procedure below will allow you delete all system caches since we can’t delete them one by one. For this, you don’t have to do anything as none of your files, data and settings will be deleted. It is very effective for update related issues and it might just save you from a lot of trouble. Here’s how…

Turn off your Samsung Galaxy S7.
Press and then hold the Home and Volume UP keys, then press and hold the Power key.
When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
Once highlighted, you may press the Power key to select it.
Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
The phone will now reboot longer than usual.

Step 5: Try to reset the Network Settings in your phone

So, you already wiped the cache partition and the problem still persists. It’s safe to assume it’s not the system caches that’s causing the problem. Now, it’s time to reset the network settings of your phone as it may have been messed up for some reason. Here’s how…

Swipe down from the top of your screen to pull the Notification Shade down.
Tap the Settings icon that looks like a cog wheel.
Scroll down a bit to find Backup and reset option.
Now tap Reset network settings, then RESET SETTINGS.
Tap RESET SETTINGS again to confirm your action.

Alternatively, you can just open the phone app and dial ##72786# and tap YES to reset the network settings.

Step 6: Try to reset your phone to see if that makes a difference

At this point, you have no other option but to do the master reset to rule out the possibility that it’s just a firmware issue. This procedure clears both the system cache and data, which deletes all third-party files saved in the phone’s internal storage, apps, settings, your preferences, etc. Needless to say, it brings to phone back to its factory settings, although if it has been updated recently, the new firmware remains.

Turn off your Samsung Galaxy S7.
Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
Once highlighted, you may press the Power key to select it.
Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
The phone will now reboot longer than usual.

Step 7: If all else fails, send your phone in for checkup

After the reset and the problem remains, then it’s time you sent your phone in for checkup. Your service provider may be able to help you or you can go to Best Buy and consult with a Samsung technician. The reset is all you need to do to rule out the possibility of a firmware issue but if it remains after that, then it might have something to do with the hardware. Further tests are necessary to determine what the problem really is.

Samsung Galaxy Note 5 needs to dial twice for calls to go through, can’t make or receive calls after update, more call related problems

We did receive a lot of call related problems from Samsung Galaxy Note 5 (#Samsung #GalaxyNote5) owners and it seems like the most common of them all is the other party can’t hear the other or the audio coming from the earpiece cuts off in the middle of the call.

There’s also a problem with the phone wherein a contact needs to be dialed twice so the call will go through and one of our readers said this issue occurred after an update. Firmware issue? Maybe. It can also be a network problem.

Read on to know more of these problems and how to fix them in case you’ll encounter one. If you are looking for a solution to a different problem, then browse our troubleshooting page as we list down every problem we address each week. Odds are we already addressed your issue or there are other problems related yours. Feel free to use the solutions we provided and if they won’t work, then you may contact us by filling up this questionnaire.

Here are the problems I tackled in this post…

Needs to dial twice to make outgoing calls
Can’t make and receive calls after an update
Other party can’t hear the owner and vice versa
Problem with Advanced Calling
Call audio cutting off in the middle of the call

Galaxy Note 5 needs to dial twice to make outgoing calls

Problem: After the update to Lollipop, every time I go to make a phone call, I need to dial twice. I will go to my contact list, select the contact I want, select the number I want to dial and then push the phone button. The number starts to dial and then stops and takes me back to my contact list. A second attempt following the same steps and I can make the phone call. This only occurs once and then the phone works as expected, unless I lock the screen and try again. Then I can repeat the problem. It also repeats if I close all windows and launch the phone app again to make a phone call. It occurs both when I attempt to call a saved contact, a typed in number and even selecting a number from recent calls. Any help would be greatly appreciated. — Mark

Troubleshooting: Hey Mark! This issue is actually minor and it may either be caused by the update itself or a simple sync issue with the network. That said, the first thing I want you to do is to wipe the cache partition:

Turn off your Samsung Galaxy Note 5 completely.
Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
Once the Android logo shows, release both the Volume Up and Home buttons.
The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

If wiping the cache partition didn’t work, then we already ruled out the possibility that the recent update caused this. The next thing to do is to disconnect from the network and manually reconnect. Follow these steps:

From the Home screen, tap the Apps icon.
Find and tap the Settings app.
Scroll to ‘Connections’ section and tap Mobile networks.
Touch Network operators.
Tap Search now and connect to your network.

Dialing twice before the call goes through means the phone is out of sync and reconnecting will rectify it.

Lastly, if the first two procedures fail, then you should call your service provider and let the rep fix the problem for you.

Can’t make and receive calls after an update

Problem: Just got this phone 2 days ago. I was able to make and receive calls until this morning after the software updated. Now when I try to call out I get a message that the person is unable to receive a call and the person calling me doesn’t get a response and I hear nothing. Phone does not ring. Please help.

Suggestion: Does it happen to every person you call? If so, it’s a network or service issue. Call your service provider for that. However, if it happens to only one contact, then the problem isn’t with your phone but the other.

Now, about the other problem, try to verify if your phone can receive a call but there’s no notification. If it can’t and the calls go straight to voice mail, then it’s still a service problem and calling your provider is your best bet. Otherwise, just make sure the notification is turned on.

Other party can’t hear the owner and vice versa

Problem: Frequently during phone calls either the other party can not hear me or I can not hear them although the call still shows to be connected.

Suggestion: I’m not sure how frequent this problem happens or if it occurs only to one specific contact. If it happens to only one contact, then the problem might be on the other line but it if happens to every contact, then it’s probably a service problem. Call your provider and do the troubleshooting with the rep. If that won’t work, then request a replacement.

Problem with Advanced Calling on Galaxy Note 5 (Verizon)

Problem: I have many contacts on my phone where I use a calling card to reach them in a different country and therefore, some of the phone numbers are for example many digits: a 1-800 number, several commas, then a long phone number, then several commas and then the calling card account number. If I turn on advanced calling, most of the commas are ignored and everything after the first comma is never dialed. Someone suggested I try “p” instead of a comma, but on the phone I am unable to enter any letters in the phone number field. Help! How can I dial these numbers but still have advanced calling turned on?

Answer: That’s one problem that we, phone owners, can’t fix. Advanced Calling, while it has already been offered for some time, may still need a lot of improvements. I suggest you call Verizon for that and if they, too, can’t fix it, at least, it has already been reported.

Call audio cutting off in the middle of the call on Galaxy Note 5

Problem: Hi, only problem is when taking a call or calling someone. Sometimes earpiece does not work but other line can hear me. I tried speaker phone but still the same or even using headphones. But normal sounds like videos or music plays on speaker. Other line can hear me perfectly fine but I cant hear anything. Sometimes its working, at times it just cuts off in middle of conversation. Thanks for your time.

Related Problem: Hi all, just got the note 5 last week. I’m losing calls. I’ll be on a call and then I no longer can hear the other person bit they can hear me. My phone will show that I’m still on a call and then it will eventually disconnect. Has anyone else reported a similar issue?

Suggestion: It is apparently a hardware problem. We don’t know if the phone suffered either physical or liquid damage but the best course of action here is to call your service provider. You may be eligible for a replacement unit.

How to troubleshoot Samsung Galaxy S7 Edge Calls & Texting problems

Calls and text messaging are the most common services a phone should have and there’s no exception to that. However, reports from our readers suggest that the new Samsung Galaxy S7 Edge (#GalaxyS7Edge #S7Edge) has some issues making outgoing and receiving incoming calls as well as sending and receiving text messages.

In this post, I will guide you through in troubleshooting these problems, so read on to learn about them as well as their fixes. But please note that there’s no guaranteed fix for now and the purpose of this article is to guide you in learning what the problem is all about so that you can formulate a way to fix it or at least explain to a technician what’s happening with your device.

With Galaxy S7 and S7 Edge released a little more than a week ago, you should still be within the replacement period so if troubleshooting fails, you can still have it replaced.

Now, before going any further, if you have other problems with your S7 Edge, visit our troubleshooting page as we list down every problem we address each week. Try to find issues that are similar to yours and use the solutions we suggested. If you can’t find a relevant problem or if you need further assistance, then fill up this questionnaire to contact us directly.

Troubleshooting Calls & Text Issues

The troubleshooting steps I use here are very basic but very important because there are times when issues like this aren’t really problems but misconfigurations, glitches, bugs or caused by apps that gone rogue.

Step 1: Try to see if there’s an airplane icon on the status bar

When the Flight Mode is turned on or enabled, you will see that icon at the top of the display and at the same time, by default, all wireless communications are disabled. So, device won’t get any signal or coverage and this might be the reason why you can get your calls and texts out nor receive any of them.

Disabling the Airplane Mode will fix the problem in this case.

Swipe from the top of the screen to pull down the Notification bar.
Touch on the Settings icon.
Tap Flight mode.
Touch the switch to toggle it from On to Off.

Alternatively, you can just press and hold the Power key and touch the Flight mode icon to toggle it On/Off.

Step 2: Check the signal bars to know the quality of the service

Are you in the area where there’s excellent service coverage?

If you were getting just one or two bars of signal, then that might be the reason why you’re not able to use both the calls and texting services.

While this problem concerns your service provider, if it happened just recently, there’s a chance it’s a glitch in the phone’s hardware. Try rebooting your device and see if that makes a difference. If not, you should try calling your service provider and inquire whether there’s an outage in your area or not.

Step 3: Try doing the master reset to bring the phone back to default settings

To rule out the possibility that it’s just a misconfiguration or some corrupt caches or data caused it, it’s better you do the master reset. This is also in preparation before you send the phone in for checkup or replacement.

But before you actually do that, make sure you backed up all your data as they’ll all be deleted. Move them over to your SD card if you have one mounted on your device.

Then remove your Google account and turn off the screen locks so as not to trip FRP or Factory Reset Protection (anti-theft feature). Then, follow these:

Step 1: Turn off your Samsung Galaxy S7 Edge.

Step 2: Press and then hold the Home and Volume UP keys, then press and hold the Power key.

Step 3: When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

Step 4: When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Step 5: Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Step 6: Once highlighted, you may press the Power key to select it.

Step 7: Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Step 8: Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

Step 9: The phone will now reboot longer than usual.

If all else fails, have the device replaced as soon as possible.

I hope we were able to help you through this post or at least, shed some light to the problem. Issues like this may range from simple app issue to a firmware and hardware problem to a network or account status troubles.

How to fix an LG V35 ThinQ smartphone that cannot make or receive phone calls [Troubleshooting Guide]

Network problems are usually the main factors that can prevent a device from making and receiving phone calls. This can happen unexpectedly to any device whether it’s new or old. Other factors that can affect calling functions of the phone are faulty updates, errant apps, invalid/incorrect settings, account issues, and a bad SIM card. In worst case scenarios, a device may also not be able to make and receive phone calls due to hardware damage. This is usually the case when you accidentally dropped your phone or got it wet.

Tackled in this post is a pertinent issue affecting the new LG V35 ThinQ smartphone. If by any chance, you’ve landed into this page while searching for more inputs on how to deal with calling problems on the same device, then this post might be able to help you out. Read on to learn how to troubleshoot and fix an LG V35 ThinQ smartphone that is unable to make or receive phone calls.

Now, before anything else, if you have other issues with your phone, make sure you drop by our troubleshooting page for we have already provided solutions to hundreds of problems reported by our readers. Odds are that we may have already provided a solution to the problem you currently have so try to find issues that are similar with yours on that page and feel free to use the solutions we suggested. If they don’t work or if you need further assistance, fill up our Android issues questionnaire and hit submit to contact us.

First solution: Soft reset or reboot your phone.

Random software errors may affect the network functions and should that happens, network-related apps and services particularly calling functions will likely become unstable. If it suddenly occurs that you cannot make and receive phone calls on your LG V35 ThinQ, the first and simplest solution you can try first would be a soft reset or reboot. Here’s how it’s done:

Press and hold the Volume Down and Power buttons together for at least 8 seconds until the phone restarts. Or you can also press and hold the Power/Lock button and then select Restart from the menu options.

A soft reset dumps cache and rectifies software errors that might have halted your device from making and receiving phone calls. This won’t affect any personal information you store on the internal memory, thus backing up files won’t be necessary.

Second solution: Turn Airplane Mode on and off.

This old trick has already done wonders to a lot of phone users who dealt with various types of network-related problems including calling issues. Turning Airplane Mode automatically disables wireless connections. Toggling this feature on and off works the same as restarting wireless network functions of the phone. Here’s how it’s done:

Swipe left from the Home screen, then tap Settings.
Go to the Network tab.
Scroll to and tap Network & Internet.
Scroll to Airplane Mode then tap the switch next to it to turn the feature on.
If prompted, read the Airplane mode message then tap OK.

After a few seconds, navigate to the same menu to turn Airplane Mode off again. Then try to make a test call and see if it’s already working as intended.

Third solution: Enable Safe Mode.

Errant apps, particularly network-related apps you’ve downloaded maybe also halting your device from making and receiving phone calls. To determine whether a third-party app is at fault or not, try to boot your LG V35 ThinQ in safe mode. Doing so will prevent third-party apps from running, thus leaving only the built-in apps active. Here’s how to enable safe mode on your LG V35 smartphone:

Press and hold down the Power button for a few seconds until the Power off icon appears.
Touch and rest the Power off icon until the Restart in Safe Mode prompt appears.
Tap OK then wait until the phone reboots in safe mode.

Alternatively, you can enter safe mode using the physical buttons. Here’s how:

Turn the phone off by pressing the Power button and then select Power off.
Then turn the phone on while pressing and holding the Volume Down button.

You will know when your phone is already running in safe mode if you see the Safe Mode label at the bottom of the screen. Once you see that label, try to make a test call. If you can make and receive phone calls while in safe mode, then that clearly denotes that the problem is triggered by a third-party application. In that case, you can delete individual apps starting from your most recent download. Don’t forget to test your device after deleting an app so that you’ll know when the problem is solved.

If you still cannot make or receive phone calls while in safe mode, then you are most likely dealing with a complex software issue on the phone, if not hardware damage. In this case, you may continue to troubleshoot your device or take it to a technician.

Fourth solution: Reset network settings.

To clear network errors, performing a network settings reset on the phone can help. Doing so will delete all current network settings including APN settings on your phone. Should there by any errors in your current network configuration that may have halted you from making or receiving phone calls, then that should also be cleared. To reset network settings on your LG V35 ThinQ, follow these steps:

Tap Settings from the Home screen.
Tap the ‘General’ tab.
Tap Restart & reset > Network settings reset > RESET SETTINGS.
Finally, tap Reset Settings to confirm action.

When the network settings are completely reset, you will see the ‘Network settings have been reset’ message that flashes quickly on the screen.

Fifth solution: Remove and reinstall your SIM card.

A bad SIM card in use can also be the main reason why you won’t be able to make or receive phone calls on your device. It’s possible that the SIM card is loose or dislodged and therefore needs to be reseated properly. This means the need to remove the SIM card from your LG V35 ThinQ smartphone first. Before removing the SIM card, turn off your phone completely. Doing so will prevent causing any sort of damage to your device.

Insert the SIM eject tool or small paperclip into the small hole to on the SIM and microSD card tray to eject it. The SIM and microSD card tray is located on the right side of your phone.
Carefully remove the SIM card from the tray.
Then, place the SIM card back into the tray with the gold contacts facing down and the notched edge should be on the upper left.
Gently press the SIM card in until you hear it clicks into place.
Insert the SIM & microSD card tray back into the phone.

After securing the SIM card tray, turn on your phone and then try to make a test call and see if it already goes through this time.

Other options

If you still cannot make or receive phone calls on your LG V35 ThinQ smartphone after exhausting all applicable solutions and workarounds on your end, contact your carrier or network service provider to escalate the problem for further assistance and recommendations. Check and ensure that everything is good in your account and that your SIM card is properly provisioned. If you suspect that the SIM card is at fault, then you may request for a new SIM card replacement. Or you can take your device to the nearest LG-authorized service center in your place, for it to be thoroughly checked by a technician. The problem may also persist if hardware damage is present. In that case, your phone needs service. Don’t forget to avail for warranty, if your phone is still covered.

Problem 1: Galaxy S7 keeps overheating, works fine when in safe mode

The battery gets hot and phone resets. I rebooted in safe mode and it stopped resetting. I deleted most recent apps, but it would still reset. The only time it did not reset was when the phone was in safe mode…or when in normal mode with airplane mode. I am outside of the USA. Anytime I turn on the wifi to get an internet connection, the phone battery will get hot and within a couple minutes it resets. — Justin

Solution: Hi Justin. One of the results of an overheating phone is untimely reset. That’s a built-in mechanism to prevent heat from damaging the motherboard. If your phone won’t overheat in safe mode for an extended period (we assume you’ve already tried it before contacting us), that’s a clear indicator that a third party app or service is hogging resources causing the system to eventually overwhelm itself. Apparently removing recent apps is not enough. You should continue to eliminate possible problematic apps until the overheating issue stops. Once the phone stops overheating, that’s the sign that the buggy app has been removed from the system.

Problem 2: Galaxy S7 not receiving app notifications after an update

Hi. Since I did an update on my S7 a couple of months ago, I’ve stopped receiving notifications from apps. I do get text messages, missed calls. However, I’ve stopped receiving WhatsApp, Snapchat, Twitter and emails. Last year when I did the update, I stopped seeing contact names when they called. This recent update corrected that. But, has stopped my notifications. If I go into the apps, I can see my messages. But, it never comes through. My Gmail might come through, but only if I open the app, with for a few seconds then exit. This doesn’t work for Outlook or Snapchat though. Thank you for your time and assistance. Kind Regards. — Anandraadams

Solution: Hi Anandraadams. The first thing that you want to do is to wipe the cache partition. This will clear the current cache and replace it with a new one. Sometimes, updates and app installation can corrupt this type of cache so it’s good if you can deal with it first. Here are the steps to do that:

Turn off your Samsung Galaxy S7.
Press and then hold the Home and Volume UP keys, then press and hold the Power key.
When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
Once highlighted, you may press the Power key to select it.
Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
The phone will now reboot longer than usual.

Sometimes, installing app updates can also fix post-Android update issues. Make sure that you only install updated and compatible apps.

If that won’t help either, do a factory reset. Refer to the steps below.

By default, apps should make sound notifications after a factory reset. Make sure to go under Settings>Notifications to check if sound notifications for your important apps are set properly.

Problem 3: Galaxy S7 edge screen remains black, won’t turn on

I have a Galaxy S7 Edge with some issues. Currently my phone has the black screen of death so I can’t see the screen display. I’ve tried to hard reset the phone and when I do the screen is still black, but the blue light that usually lights up is there. I’ve tried to turn the phone off to try to manually factory reset it but I can’t turn it off. So I think that the touch screen is unresponsive.

When I press the power button as if I were to wake the phone the LED touch buttons at the bottom light up, but a brief green flash appears on the screen and disappears. I also had issues with my display before the black screen of death. Before this issue, I had to keep the screen on auto brightness turned up to 100% otherwise there would be green with a double vision like purple display. The lower the brightness the worse it got. So I tried to restart the phone, which ended up in the black screen of death and my unresponsive touch screen. I have no idea what to do. — Dakota

Solution: Hi Dakota. There’s nothing much that you can do about this issue. If the screen remains dead even if you try to boot the device to alternate modes, that means that the screen assembly is broken. You need to have the device checked so it the hardware can be assessed. The most likely outcome is a screen replacement. If your phone is within the warranty period, make sure to take advantage of whatever freebie you can avail.

Problem 4: Galaxy S7 keeps getting a blank blue screen and moisture detected error

My S7 edge was getting a blue screen blank and it is less than 3 months since I bought it. I had to drain the battery and completely recharge it to get it to work. It is continuing to do this at random. It seems like a software glitch. It’s like the screen of death!! Keeps saying there is moisture in the USB port and then won’t charge but took to the phone store and no moisture in the phone on the indicator. But they won’t do anything either. Honestly I can’t tell you the version because it is dead again Frustrated!!! — Geoffrey

Solution: Hi Geoffrey. Your Galaxy S7 has water resistance protection and part of that protection is the moisture detected warning you’ll get when the system detects moisture in the charging port area. As long as the device is reading that there’s moisture in that part, it will never charge by cable. If your phone was never near water recently and you’re 100% positive that there’s no moisture in the charging port, then it’s possible that the system is getting incorrect readings from the charging port. Keep in mind that smart as your phone is, it’s not that smart enough to actually check if the reading it receives from the charging port is true or not.

The erratic moisture detected error and the random screen of death issue may be signs of some deeper hardware problem so if a factory reset won’t fix them, send the phone in.

Below are the steps on how to factory reset your device:

Turn off your Samsung Galaxy S7.
Press and then hold the Home and Volume UP keys, then press and hold the Power key.
When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
Once highlighted, you may press the Power key to select it.
Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
The phone will now reboot longer than usual.

Problem 5: Galaxy S7 edge keeps overheating, keyboard not working

Good evening. I’ve recently bought a Samsung Galaxy S7 Edge in Germany, and moved in to Brazil. Today, my phone’s keyboard all of a sudden stopped showing up. As I start the phone, everything else in the phone – every app, even the keyboard’s app – still works fine. But then, the phone restarts and get really hot in a specific area of the phone. I’m desperate, I have thousands of pictures which are really important to me there and aren’t synchronized with the cloud. I’ve restarted the phone countless times and wiped the cache out to no effect. I’ve also restarted the phone in Security mode, only to experience the same issue. If you think that a hard reset is necessary, is there any way I could retrieve my data? — Pedro Angst Maciel

Solution: Hi Pedro. You need a working touchscreen to allow an external device like a computer to access files in the phone. The phone also has to stay on long enough to allow the transfer to files to finish. If both are not satisfied, you can’t really create a back up of your files.

Try to bring your phone to your local shop and see if there’s anything that they can do about it, especially regarding the overheating issue.

Problem 6: Galaxy S7 mobile data is spotty, SMS won’t send

Just recently started having issues with my phone in the last couple weeks or so. Data is suddenly very sketchy in places where I never had problems before, like at my office downtown. Try to get on Facebook or something else and just get the “loading circle.” So I turn on the WIFI at the office and internet works fine but then I am unable to send any texts unless I turn the wifi off. If I attempt to send a text with the wifi on, it just says “sending” with the loading circle and it will do this forever, or until I turn off the wifi. I have never had these kinds of issues before and am not sure what is going on.

Also, I used to have full bars at my office, now only a couple. Not sure what is going on. — Jess

Solution: Hi Jess. If basic software troubleshooting like a cache partition wipe and factory reset won’t help, then the problem is either network related, or something with the phone. We suggest that you contact your carrier so they’ll know that you’re getting weak signal in an area with a previously good coverage. You also want to let them to help you with that text sending problem.

If they’ll say that everything’s good on their end, then it’s most probably a phone issue. Make sure that you do a factory reset and install Android updates afterwards. If both procedures won’t work, consider getting a new phone.

Problem 7: Galaxy S7 not receiving SMS using stock messaging app

S7 stopped receiving texts. I’ve done everything short of a factory reset. Which really I don’t have the time for. But the issue is fixed when I download a third-party messaging app. all the sudden my text work and it even sinks them into the stock messaging app. But once I uninstall the third party app Go SMS Pro, all the sudden I get no texts again and the stock messaging app stops working again and I get a message up that says messages has stopped working.

I uninstalled Go SMS Pro just to check and see if maybe my text were working again so want to go pay a bill and at the moment when I’m expecting the text that payment was received instead I receive a message saying messages has stopped working on my Android touch screen. — Vertimusmaximus

Solution: Hi Vertimusmaximus. Make sure that you delete the messaging app’s cache and data first. Here’s how:

Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
Once in there, click on an application.
You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
You should now clearly see the Clear Cache and Clear Data buttons for the application.

If that won’t fix the issue, restart the phone to safe mode and see if the stock messaging app works. Safe mode blocks third party apps and services so it’s a good way to know if an app is responsible. Below are the steps to boot to safe mode:

Turn your Galaxy S7 off.
Press and hold the Power button.
Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
Continue holding the button until the phone finishes rebooting.
Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button

If it still fails to receive SMS, that’s the time that you want to do a factory reset.

Problem 8: Galaxy S7 froze showing a black screen

Hello. I have a problem with my phone. I was having trouble connecting to my internet so I told my phone to restart. Sometime while it was restarting it froze on a black screen while the notification light was blue. tried holding all the power home and volume button combinations I could think of and find with a google search and eventually lead me to your page. Please let me know what I can do. Thank you. — Sheldoncheeks69420

Solution: Hi Sheldoncheeks69420. You should try to do a simulated “battery pull,” also known as soft reset. Here’s how:

Press and hold the Power and Volume Down buttons until the Maintenance Boot Mode screen appears (approx. 10 seconds).
From the Maintenance Boot Mode screen, select Power down. Utilize the volume buttons to cycle through the available options and the Home button (located below the display) to select.

A soft reset should force the phone to restart to normal mode. If that won’t help, do a factory reset via Recovery mode. Check the steps above.

Problem 9: Galaxy S7 stuck in boot loop, screen remains black

While charging I got a Whatsapp message. then I opened and read it, suddenly it goes tinted blue screen. I removed it from the charger and I tried to restart it. when I press and hold power button for around 20 seconds, I got the logo and after 1-2 seconds it disappears. I keep on doing this, but my problem is, I can’t see anything, but I got message notification sounds. the notification light blinks, I don’t know what is the problem. but I am unable to see the screen, but I am able to boot to recovery. Please let me know the solution. — Srikanth

Solution: Hi Srikanth. Your phone may have become stuck in Samsung logo page, or doing a boot loop. Since we don’t know the full history of the device, there’s nothing much that we can say. However, if this issue started after you installed an update, or after flashing or rooting, you may to do a more drastic solution. That solution is to try and flash the bootloader and/or firmware back to stock. Below are the sample steps on how to flash a bootloader. They are provided here for demonstration purposes only so be sure to do your own research on how to flash a bootloader for your particular phone model.

Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
Proceed with the rest of the flashing procedure using the Odin program.
In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
Restart the phone once the procedure is finished.

Problem 10: Galaxy S7 not receiving calls and SMS

So my phone was doing fine for the first 3 weeks until my phone started getting issues. I would be able to text people and call them but not receive texts or calls. Sometimes I would be able to receive some texts but hours later when it was sent. Now, my phone doesn’t receive neither text messages or phone calls. I tried resetting and taking out the SD card, but didn’t work. I checked to see if it had to do anything with an app but it wasn’t that either. Also checked to see if it was on block mode but it wasn’t. If you can help that would mean a lot. Been trying to fix it for a couple of days now with no help. Maybe there’s a setting I new to change. I don’t know. — Alec

Solution: Hi Alec. If your phone was able to receive calls and text before, then it’s either a device configuration issue, or something network-related. Contact your carrier and ask help on how to reconfigure your device (assuming their network is working fine at this time).

Problem 11: Galaxy S7 won’t detect 2 SIM cards

I have been using my phone since April, 2016 when I bought it. All of a sudden, 2 weeks ago, the 2G compartment stopped connecting to network. It refuses 2 SIM cards activeness on the phone and as such disrupts my call and browsing activities. The phone did not fall, I just can’t understand what’s happening.

Meanwhile, if I insert the SIM cards in other phones, they work well but in my S7, I can’t make calls, send messages, receive calls or browse with either of my two SIM cards . The network signal for the 2G compartment disappears, indicating 2 SIMs can’t be active at same time. I got your mail address from a Samsung forum Casey. — Caseygem4u

Solution: Hi Caseygem4u. If you’ve already tested two known working SIM cards on this phone, then that’s a clear indicator that something is not working properly on the device. Make sure that it’s running the latest Android version by installing updates. If you are an adventurous type and recently flashed a custom ROM or rooted the device, make sure that everything is back to stock.

You also want to see what happens when you factory reset the phone so be sure to that if you’ve already installed all Android updates.

If the phone still fails to detect any SIM card, have it replaced.

Galaxy Note 4 keeps rebooting on its own after a power surge, screen is unresponsive, other issues

Hello Android community! Welcome to another #GalaxyNote4 article and as usual, we’re bringing you different issues and solutions. Don’t forget to visit our main Galaxy Note 4 troubleshooting page should you not find anything useful for you here.

Problem 1: Galaxy Note 4 keeps rebooting on its own after a power surge

Hi, this is my problem. I own a Galaxy Note 4 since some time. The phone is not rooted, nor cooked. The only different thing from plain original phone is the battery, which is a Mugen Power 6640mAh battery with used to work very well for 6 months (approximately November-December).

The actual situation is a phone that does not turn on. What is happening is that, without power connection, the phone keeps rebooting itself and is not starting up. With “rebooting itself” I mean that, when I press the power button, the phone turns on, I can see the “Samsung Galaxy Note 4” and it immediately reboots over and over. (The Samsung logo is the white one that appears immediately after releasing the power button, NOT the animated one with flashing status led).

Connecting the power cord does not help, since the phone goes again into a boot loop but this time it reboots as soon as the battery logo appears. I happened to interrupt this booting loop once and the battery seemed to be able to recharge.

The story of this phone starts a bit far in the past, though. Since December, the phone kept rebooting itself in random occasions and in random ways. I have not been able to figure out “why” it kept behaving like that, meaning that I was not doing the same things when reboot happened, nor I had been using the same applications…it all seemed really random and impossible to reproduce. The only thing that I noticed was that it used to happen more often when the phone hotter, than when it was colder, but apart from that, nothing so common to be identified as the cause of the problems.

The only odd and strange thing that I noticed was that, again on random occasions, the phone was unable to reboot at the first try, but it had to reboot twice or more to be able to successfully reboot and it behaved, again randomly, in some puzzling ways displaying strange things on the screen (blue, green and red pixels spread on the screen, together with the fixed Samsung logo instead of a uniform black background). This was going on since December and apart from the annoyance of the continuous reboots, nothing really happened. (No more signs of hardware decay, no memory problems, no corrupted data, nothing at all).

The only thing that I noticed, because the back cover was not able to stay shut anymore, was a battery swell, that I noticed in the last few days. Today, after the nth reboot, the phone suddenly didn’t woke up at all…it just kept rebooting like said at the beginning of this message. I was not at home and thought that the battery had collapsed and needed to be replaced. (Fortunately I ordered a new battery a few days ago, because of the swell that made me think a near fail). In the meantime I thought that until Friday I could use the old original Samsung battery which the only fault was to have way less power than I needed (I don’t recall issues with that one, even if it stayed unused for near a year).

Once at home, I switched the batteries and really bloody nothing happened. The phone kept behaving like it did with the Mugen battery. This puzzled and frightened me a lot, since I thought that, even if old, the original battery would had solved the problem.

In three days I’ll be able to tell if the new battery solves the problem (maybe I’m only unlucky and the Samsung original battery while in the box developed some problems that I’m unaware of), but in the meantime I don’t know what to do. I’m only 50% frightened of not being able to resuscitate the phone anymore, because pictures and videos were stored on the external SD card (which after the first time trying to start the phone was pulled out to both save her from damage and ensure that it was not the cause of the fault) and backed-up elsewhere, but SMS, WhatsApp and Telegram chronologies as well as some game progresses that are tied to the internal memory were not and only old backups do exist, not to speak about “Samsung memo” files which were not backed-up at all. It would be not deadly but really awful to lose this data.

What I did was the following:

Remove the battery and tried to start the phone without: No signs at all.

Remove the battery for 30 minutes and try to start the phone (both with and without SIM and SD Card): Boot loop like above

Start phone in recovery mode: The recovery mode is recognised, a “Android is installing updates” appears, then reboot and boot loop.

Start phone in download mode: The download mode is recognised and it starts successfully. I’m able to press the volume up key and go into the next stage in which the phone is awaiting to download something (these are the strings appearing: ODIN MODE: High Speed – Product Name: SM-N910F – Current Binary: Samsung Official – System Status: Official – Reactivation Lock: ON – Knox Warranty Void: 0x0 – Qualcomm Secure Boot: Enable (CSB) – RP SWREV: S1, T1, R1, A1, P1 – Secure Download: Enable – UDC: Start).

I did not go further since anything I do, might damage data; the only thing I did was to connect the phone to my PC and notice that the phone was not showing up, even if the driver installed correctly. But I believe this thing to be right, since in download mode only Odin is able to access the phone. I did NOT try to connect to the phone via adb nor know if, via adb, is possible to connect to collect phone data. I don’t think that there is much else to say, apart from an accident the phone had this December.

One day, an underground cable broke (the N of a three-phase cable) in the flats of a friend I was visiting and all the 8 apartments got a shocking 380V power surge in the sockets for quite some time. Since the thing was happening the second time, my friend was aware of the problem and when his TV begun to behave strangely, he ran to disconnect my PC and mobile phone from the outlet. The PC continued to work flawlessly, so did the Phone, but from that time on, reboots begun to happen (damaged battery?).

The surcharge for my appliances happened for only 10 minutes because after that they were disconnected (differently from a dvd reader that blew up) but that time might had been not enough to blast the phone to pieces but enough to cause some sort of damage to something I’ve yet to discover. (really light damage if the phone survived for 6 months being still operative, apart from reboots).

If the phone is to be scrapped then this is no big problem. What I need is to be able to do something to start it up and recover some data. From my experience (computer science degree), what is happening might be related to energy supply, having the phone to thing there is no more power, when indeed there is plenty of it. (where does the phone gets this information? it measures the voltage coming out from the battery or it queries the battery for informations that might be wrong, so even if there is power, the battery reports itself as drained?)

But there might be other things to take into account: I asked myself whether the internal storage have become corrupted or even failed completely, but I believe that download mode would not even start in case of a failed flash ROM. (correct me if I’m wrong) Does the phone asks for the battery serial number so it remembers it is faulty and refuses to boot up? Could the phone power management circuitry be broken so that it is unable to distinguish drained from full battery? Could the continuous reboots have damaged the ROM, because one of them occurred when an application was writing on it?

Too many questions but I’m unable to answer. So here is the big one: While waiting for the battery to be delivered, is there something else I might try to revive the phone?

Thank you in advance. — Gabriele

P.S. Tech Specs of the phone are the following: Phone: Samsung Note 4 OS: Android 6.01 with latest security patches applied Root: No Custom Roms: No Battery: Mugen Power 6640mAh HLI-N910XL

Solution: Hi Gabriele. We appreciate the time and effort in giving us a very detailed description of the problem and history that might had led to it. If only most users who contact us are as detailed, it should make it a lot easier for us to identify the issue.

First of all, we want to make it a point that almost all Android issues can be caused by either a software glitch or hardware malfunction. Knowing which is which is always tricky and does not always guarantee a solution that a user can do on his or her end. Although majority of software-related problems are fixable at a user’s level, some may still require intervention from Samsung or carriers because they’re simply way beyond a user’s ability to solve. That said, we usually go through a series of logical troubleshooting steps to help a user narrow down possible causes, especially if they don’t mention the troubleshooting steps they’ve already tried before contacting us. In some rare cases like the one you’re doing here, we can skip the usual troubleshooting steps because you’ve already performed them ahead of time.

For instance, a random reboot issue like the one you’re experiencing here will require checking a number of things such as:

the battery (to see if it shows physical symptoms like bloating)
the apps (by booting the device to safe mode or doing a factory reset)
the bootloader (by flashing it with a stock one, especially if you’re running a non-official firmware, or if you rooted the device)

That you’ve already did these checks ahead of time gives us better insight as to what may be happening.

Secondly, we think that the main problem here is caused by a hardware malfunction. Remember that power surge at your friend’s place? We are almost certain that’s where the problem started. Although power surges happen all the time, majority of them are negligible and most household electronics including smartphones can handle them without incurring any negative effects. However, in some rare cases like the one that happened in your friend’s place, the sudden extreme voltage spike must have generated enough heat within the power IC and the circuit board to cause the problem right now.

Keep in mind that power surges can both have instantaneous and long term effects. In some cases, an affected device may simply fail right away, while in some, the damage won’t really become apparent until at a much later time. Smaller power surges can slowly degrade electronic components, effectively shortening the overall lifespan of a critical parts like the power IC.

We have no way of knowing which of the two is happening on your device right now but we believe that the power IC may have been damaged. This is often the main reason for unexplained random reboot problems in many Samsung devices. There’s been mixed results in replacing the power IC because it’s also possible that other components may be malfunctioning as well. In most cases, Samsung service centers and a lot independent service centers will opt for a full motherboard change instead of spending more time checking hundreds of components individually.

Do-it-yourself repair won’t be of much help either. Unless you’re lucky and the issue is isolated to the power IC only, which is highly unlikely given how you arrive at this predicament right now, motherboard replacement is the only effective solution that you can do on your end. To do that, we assume of course that you have access to needed tools and has the knowledge to do basic electronic stuff. If you think you can do a motherboard replacement yourself, try looking for a good guide from some websites. iFixit is a good place to start.

Thirdly, no, this is not a battery issue. We don’t think getting a new replacement battery will improve the situation but you can definitely try that. And no, a smartphone like your Note 4 won’t question a battery inserted to it for a serial number. As long as the specifications of the battery connected to your phone match what its needs, there shouldn’t be any problem.

As regards your question “is there something else I might try to revive the phone?” it depends on the extent of damage on the system. Unfortunately, there’s no way to know that for sure. We know that your ultimate aim is to recover your data but again, that depends how long your phone stays on to allow file transfer. Because the issue is a malfunctioning hardware due to unstable or unmet power in the circuit, there’s no amount of software tweaks that you can do to bring everything back in order.

Problem 2: A portion of Galaxy Note 4 screen is unresponsive

Hello. I have a Samsung Galaxy Note 4 SM-N910F which I purchased 9 months ago. Since the first time I used the device, there was a problem in the screen that a small area of about 1 cm, exactly in the middle of the screen, throughout the width of the screen (from side to side). Is doesn’t respond to finger touches. it responds only to the S-Pen touches. Mainly, when I touch this screen area with my fingers it doesn’t respond, but sometimes it widens the screen or shrinking it. it happens with both applications or internet browsing. It also happens in soft mode. I tried to uninstall the Facebook Messenger but it didn’t help. I tried to Soft Reset it but it didn’t help. when I use the Stylus everything works fine. How do I fix it? Thanks. — Ariel.di

Solution: Hi Ariel.di. This is definitely not normal and the unresponsive portion of the screen may be a sign of a bad digitizer, one of the major components of a screen assembly. Digitizer is the top layer of the screen that converts analog touches into digital signals. Any time a portion of a screen appears to be unresponsive, it’s mostly due to a bad digitizer, which unfortunately almost always require repair. To check if your screen’s digitizer is at fault, do the following:

Open the Phone or dialer app.
Dial “*#0*#” (without the quotes).
Tap the box that says Touch.
Draw a line from top to bottom by dragging your finger. If the portion of the screen you’re having problems with shows a break in the line, that’s proof that you have digitizer issue. You should have the phone repaired or replaced.

If there’s no break in the line and the phone registers all your touches in service mode, the cause of the issue may be due to software glitch. Do a factory reset and see how it works afterwards. Here’s how:

Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
Turn off the Galaxy Note 4 completely.
Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
When the Android System Recovery shows on the screen, release the Vol Up key.
Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem 3: Galaxy Note 4 can’t receive calls, gets delayed SMS

Samsung Note 4 does not receive any calls. When someone phones, it rings at their end then cuts off. it does not go to an answering machine, just cuts off. My phone does nothing, does not light up, does not say missed call. Nothing at all. I can phone people from it and it works fine. When someone texts me, their text does not come through for hours or until I use my phone e.g. I use my mobile and phone someone and I get the text through and the text sender gets the delivery report for sent text. Could be minutes after they send text or hours. Phone has not been damaged or anything spilt on it. It just stopped working properly. There is no call barring or anything set up on phone to stop me getting calls. Please help. Thanks. — Feebeedafabriano

Solution: Hi Feebeedafabriano. Your issue appears network-related but if you haven’t tried device troubleshooting at this time, make sure that you do.

The first step that you want to do is to clear the cache and data of your messaging and Phone apps. Here’s how:

Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
Once in there, click on an application.
You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
You should now clearly see the Clear Data and Clear Cache buttons for the application.

If the problem remains after clearing the cache and data of Phone and messaging apps, do a factory reset. Refer to the steps above.

Should the issue continue after wiping the phone via factory reset, contact your carrier for direct support.

Problem 4: Galaxy Note 4 SD card got corrupted

I was at Disney World with my son when the SD card in my Note 4 suddenly stopped working. I could see pictures in Gallery but I could not delete them or do anything with them. The phone didn’t sustain any damage or anything that I know of. When I got home, I unmounted the card to try to download everything from it onto my iMac using a card reader, but the reader cannot read it and it never mounts to my desktop or shows up in disk utilities. I put it back into the phone and now I get the message “The data on this SD card is corrupt. To use it, it must be set up” and it gives me a prompt to fix. I stupidly did not back up my phone manually in almost a year because I mistakenly thought my pictures were being backed up to the cloud…I have small children so this is a terrible loss for me and I really don’t have the money to spend on a data recovery service. I think there’s a chance that if I allow the phone to go through with the fix on the card it will format and then I may be able to use a reasonably priced recovery software to get my pictures and videos from the formatted card, but I’m terrified to try. Googling this error message is yielding very few results and zero advice, can you please help me figure out what to do? — Barkingkazak

Solution: Hi Barkingkazak. It’s terrible to lose irreplaceable digital memories but once an SD card gets corrupted, there’s very little to nothing that can be done much. For one, there’s virtually no troubleshooting that you can do about it except to try and insert it to another device to see if it will read it. There are no tweaks an average user can do about a corrupted SD card.

Secondly, yes you’ll need a specialized software to recover bits and pieces from a corrupted storage medium. You read that right, just bits and pieces. Software recovery is not perfect and does not guarantee that you’ll get everything back. Recovery software, due to their highly technical nature, are only available for trained professionals. This is why file recovery is expensive and unfortunately, this is the only option available for you. We know it may be an issue for you to pay for it, but you can’t simply will this one.

To minimize losing more data, make sure to unmount the card from the phone. Do not re-insert it to another device unless you’re ready for a file recovery procedure.

Galaxy J7 can’t send email over wifi, can’t move apps to SD card, other issues

Welcome to another #GalaxyJ7 post. We’re bringing you 11 more issues and solutions related to Galaxy J7 so we hope that this material will be helpful for our community.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy J7 flickering screen issue

Hi. My name is Atul Mishra. I use Samsung Galaxy J7. before few months my phone’s screen started flickering but days after that it stopped flickering automatically. It happened again continuously for one month then it stopped flickering again. I went to service center and they told me that it’s happening because of water. somehow my phone has absorbed moisture. They told me to change the motherboard but I did not go for it. few days after that it stopped flickering again. Sometimes I noticed that it is flickering because I install some apps like kik and 4Chat but after uninstalling that app it’s not stopping flickering. Sometimes it happens because of software update. Please fix my issue. Thanks. — Atul

Solution: Hi Atul. First off, the presence of water or moisture can result to permanent hardware damage. If your phone got wet or exposed to water before the flickering issue started, stop looking for solutions. You must either follow what the service center told you to replace the motherboard, or simply have a new phone. Moisture in the motherboard almost always lead to corrosion so you’ll still end up with a defective phone in the future.

Secondly, if you are 100% positive that your phone was never exposed to water before, the cause of the problem may still be bad hardware. To check if that’s the case, do a factory reset and let the phone run without any apps installed for a few days. If the flickering screen problem continues, that’s indicative of a hardware issue. You must send the phone in for repair or replacement.

If the flickering issue won’t occur after a factory reset and during the observation period of a few days, an app may be causing it. To identify the problematic app, make sure to install apps one be one so you can observe if the issue returns after every installation.

For reference, here are the steps on how to factory reset your J7:

Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
Turn off the device.
Press and hold the Volume Up key and the Home key, then press and hold the Power key.
When the device logo screen displays, release only the Power key
When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
Press Power button to select.
Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
Press Power button to select and start the master reset.
When the master reset is complete, ‘Reboot system now’ is highlighted.
Press the Power key to restart the device.

Problem 2: Galaxy J7 can’t make calls using an app when mobile data is enabled

Hello. I got your id from internet. i am facing a problem with my new J7 mobile.

i am able to use internet by using data connection, but among all the software i am not able to use one calling application, which is itel dialer and not able to make call by using this.

On wifi connection there is no problem and on data connection it is not working.

the same app i installed on another 6 or 7 android mobiles and it is working very well on data connection.

i have updated my device software, but there is no use.

my back ground data restriction also disabled for this. Kindly advice. Regards. — Joseph

Solution: Hi Joseph. This is an app-specific question and it can only be checked by the developer. There may be a compatibility issue preventing the app from working in a J7 device. If you’ve already tried the usual app cache and data wipe troubleshooting, make sure to contact the developer of such app for support.

Below are the steps on how to wipe an app’s cache and data:

Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
Once in there, click on an application.
You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 3: Galaxy J7 mobile data won’t turn off when SIM card is inserted

Hi! I just bought a Samsung Galaxy J7, and it is causing problem with its mobile data.

Just after I inserted the SIM, the mobile data automatically turns on but I can’t use it. And when i turn off the data from the settings the data icon in the notification panel doesn’t goes away, it stays. It shows ‘H’ symbol without any sending or receiving signals. I restarted it but, the symbol on the notification panel stays on, even though the option is turned off. Even on turning on it doesn’t work, I have data of about 100MB. Solution is appreciated. — Towhidur

Solution: Hi Towhidur. There may be an operating system glitch behind this issue so the first thing that we would like you to do is factory reset.

Sometimes, a corrupted system cache can lead to all sorts of problems so if you don’t want to do a factory reset right away, you can try to wipe the cache partition first. Here’s how:

Turn off the device.
Press and hold the Volume Up key and the Home key, then press and hold the Power key.
When the device logo screen displays, release only the Power key
When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times key to highlight ‘wipe cache partition.’
Press the Power key to select.
Press the Volume down key to highlight ‘yes’ and press the Power key to select.
When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
Press the Power key to restart the device.

In case the issue is due to a third party app, you can also try to observe the phone while it’s running on safe mode. Like the cache partition wipe, you can do this before performing a factory reset. To do that, follow these steps:

Turn the device off.
Press and hold the Power key past the screen with the device name.
When ‘SAMSUNG’ appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see ‘Safe Mode’.

Safe mode blocks third party apps. If mobile data works normally with your SIM card inserted, that’s an indication that a third party app is causing it. Uninstall app until you’ve identified which of them is the culprit.

Problem 4: Galaxy J7 screen flickering at different brightness levels

Sir, i have Samsung Galaxy J7. my device has no problem but since some days the screen of my mobile start flickering. i don’t know why it happens. I am very much worried about it. half of the screen starts blinking at low brightness. When i increase the brightness, the screen show no flickering but after few hours a slight flickering again started at that brightness level. kindly help me and guide me what to do. — Rabail khan

Solution: Hi Rabail khan. We’ve noticed a flickering issue on some Samsung devices before but they can be attributed to a bug in auto-brightness feature. Yours looks like a hardware issue though so the only troubleshooting step that we can suggest is factory reset (steps provided above). Once you’re performed a reset, let the phone run for 24 hours without apps so you can observe how the screen works. If the flickering problem remains, there may be an issue with the screen assembly. To fix that, you need to have the screen replaced.

Problem 5: Galaxy J7 hardware buttons stop working when the screen turns off

Phone type – Samsung Galaxy J7.

My phone’s power button, volume button and home buttons are not working. when I take out the battery and re- install it, the screen works and even keyboards are working. Then when screen light goes off it doesn’t works as none of the buttons are working. how to fix this?

Day before the phone went off i have connected my phone to car through bluetooth and played music almost for ten hours while i was travelling.but bluetooth is off now.please give me solution.is it a software problem or what? My phones software is upto date. — Kezang Jamtsho

Solution: Hi Kezang Jamtsho. Like Rabail above, you must do a factory reset first to know if it’s a software or hardware issue. Make sure that you observe the phone for a day after a factory reset (no apps installed). If you’ll get the same problem, you must have a hardware problem. You have the phone repaired or replaced.

Problem 6: Galaxy J7 flickering screen issue after repair

Good eve! I bought a Samsung Galaxy J7 last January 2015 and 1 month after i bought it, my phone screen is flickering when i turn off my screen light. So i decided to bring my phone to Samsung gadget care due to warranty. They fixed my phone and they told me that they changed the LCD. Last month, my phone keeps on flickering again. I already tried soft and hard reset but still same result. What would be the problem on my phone? They already change the LCD but still it keep on flickering.. Hope you could help me.. Thank you in advance…. God bless. — Rogelyn

Solution: Hi Rogelyn. Please refer to our suggestions for others who have similar issue. If nothing will change after you factory reset the device, bring it back to Samsung for another repair. LCD malfunction is rare and it is usually caused by damage from misuse — dropping a phone, exposing it to water, putting the device near a heat source, etc. We seldom hear of malfunctioning screen due to a software problem or bug so if your phone suffered any physical damage before, there may be a motherboard problem causing the screen to appear to flicker. If possible, ask Samsung to give you information about the repair and cause of the problem so you can prevent the issue from happening again.

Problem 7: Galaxy J7 takes a long time to type SMS for one contact

When texting only one contact it takes a very long time for everything to load. Sometimes i will even type a full message without anything coming on the screen. I can feel the vibration from pushing the buttons but nothing comes up. Sometimes it will put a few words on thw page other times it will back out completey. I dont understand why it only happens to one contact. — Jsmittle90

Solution: Hi Jsmittle90. Make sure that you wipe the cache and data (in this order) of all the apps involved when typing a message — messaging app, keyboard app, and Contacts app.

Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
Once in there, click on an application.
You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
You should now clearly see the Clear Cache and Clear Data buttons for the application.

If wiping the cache and data of said apps won’t fix the problem, do a factory reset.

Problem 8: Galaxy J7 wifi keeps dropping

When connected to WiFi it will drop the connection and I have to scan and connect again. multiple times. My husband has the same phone and his phone stays connected.

Also Google Play Store opens by itself and I have found no adware. I have had the phone for 6 days – problem from the start but my service provider says they find nothing wrong with it. — Nelmari

Solution: Hi Nelmari. First of all, it’s not normal for Android to open an app like Google Play Store by itself. There must be something causing it. It can be a bug or a malware.

Secondly, what you want to do right now is to ensure that you start from scratch so you can then observe if wifi works normally when there are no apps installed, and if the Play Store will pull itself up without any user intervention. Do a factory reset and see what happens. If the situation won’t change, have the phone replaced.

Your second issue may be due to a bug with the app itself so you want to make sure that Google Play Store app is updated after you factory reset the phone. Be sure to allow it to install updates automatically to keep the rest of your apps updated as well.

Problem 9: Galaxy J7 not receiving incoming calls

Hello. I have a brand new Galaxy J7 2016. I am not receiving incoming phone calls. I have taken the phone to the AT&T store, which wouldn’t touch it since it is an international unlocked phone. I called customer service which disconnected me and reconnected me to the network. I have taken out the SIM card, taken out the battery, did a soft reset, and updated the APN settings. Is there anything else I can do? Thank you for your time. — Victoria

Solution: Hi Victoria. There a few things that you need to check to identify the cause of your problem. Since you never bothered to give us a history of what happened prior to noticing the problem, our suggestions may not be extensive.

Is the phone unable to receive incoming calls from one contact or multiple contacts? If you’re having a problem with a single contact only, make sure to check if you’ve accidentally blocked the number. If you’re not sure, simply delete the contact and add it again afterwards.

If you happen to have issue with multiple contacts or all callers, try to wipe the cache and data of your Phone app first (steps provided above). Once you’ve done that, make sure that you delete all your contacts from the phone and re-add them. An efficient way to do that is by creating a backup of your contacts first using Samsung Smart Switch app.

Is call barring enabled on your account or device?

We don’t know much about your particular phone model so you have to contact your carrier to ensure that your account is permitted to receive a call. Since you’re on AT&T, which is a GSM network, try to insert your SIM card to another device and call it. If you’ll be able to call it on a second device but not on the first one, that means that there’s an issue with your J7. Try to factory reset it to restore all software settings back to defaults.

If, on the other hand, you will still be unable to call your number when your SIM card is inserted in another device, the issue must be account specific. Let AT&T know about it so they can check further, or simply replace your SIM card.

Problem 10: Galaxy J7 can’t send email over wifi

Hi. My Samsung J7 can receive emails with no problem at all. If i want to send emails i have to switch my wifi off and go to my mobile data. Surely, there is something not right. I have been to my vodacom shop several times and when they send emails it works but i figured out its because i am on mobile data. How can this be fixed? I am tired of paying every time they said it’s fixed. Thanks in advance. — Dorish

Solution: Hi Dorish. In most cases, an issue like this is due to authentication problem with an Internet service provider such as the one for your home wifi. ISPs don’t want that their SMTP server will be used for sending junk emails or spam when a device is outside their network. So, they require each and every device to authenticate properly before sending an email and this may be where your issue lies. If you did not enter the Outgoing Server Authentication properly during the setup, your email provider or Internet service provider (if they are one and the same) may be blocking your emails from leaving their network. We don’t usually encounter this problem with popular email services like Gmail, Outlook, Yahoo, etc so we’re assuming you have an email account provided by your carrier. If that’s the case, you must work with them to resolve this issue. Make sure that you ask them for the correct port number to use when setting up your email account. You may also need to use SSL in this case so be sure that you cover that too.

In order to manually enter server settings for your email account, you must choose Manual setup option. If you’re using the built-in Samsung email app, Manual setup option should be available at the bottom part after you’ve typed in your email address.

If you’ll have the same experience after you’ve reconfigured your email account, continue working with your carrier for a solution.

Problem 11: Galaxy J7 can’t move apps to SD card

Hi Droidguy. I recently bought a Samsung microSDHC Card (memory card)/Class 10/HD compliant which was 32GB and I’m using Samsung Galaxy J7. My problem is the SD card keeps showing up not enough memory whenever I tried to move my apps into external storage. While in storage settings was 170MB used of 31.24GB. Every application that I successfully transferred to SD Card is missing. I had to redownload and reinstall again and again. Please help me solve my problem. Thank you. — Nurul

Solution: Hi Nurul. Not all apps can be moved to external storage. If you don’t find any option to move an app to SD card under Application manager, that means NO. it’s that simple.

However, if there’s an option to move an app to SD card under Application Manager but the phone gives you an error that there’s not enough memory in the card, there may be bug causing it. To fix that, make sure that you try another known, working SD card. If the problem remains, do a factory reset before attempting to move apps again. If the same thing happens on the second SD card, there may be an issue with your phone. In that case, you may be better off by replacing it.
