How to unfreeze a frozen Samsung Galaxy J7 Pro (easy steps)

Freezing and lagging issues are among the most common performance-related problems that android users have always been complaining about. Some of our readers that own the Samsung Galaxy J7 Pro reported to us that they encountered having their devices freeze to the point that they no longer respond. So, in this post, I’ll tackle this problem to help our readers who are bugged by similar issues.

There are time when a freezing issue will leave the phone unresponsive and there are also cases wherein the device freezes only for a couple of seconds. The former is, obviously, more complicated than the latter and that’s what I want to tackle here. I will share with you the solutions that we’ve always been using to address this problem and make your device respond again.

Before we proceed, if you’re looking for a solution to a problem with your phone, try to browse through our troubleshooting pages to see if we support your device. If your phone is in the list of our supported devices, then go to the troubleshooting page and look for similar problems. Feel free to use our solutions and workarounds. Don’t worry it’s free.

How to unfreeze a frozen Galaxy J7 Pro


I will share with you the solution to this problem with an assumption that the firmware in your hasn’t been modified in anyway because if it is, then the problem can be fixed by simply flashing the stock firmware back. But if your device just stopped responding one way without any obvious reason, here’s what you should do about it.

First solution: Forced Reboot

If you’re familiar with battery pull we often do to phones with removable batteries, then this is the equivalent of that. Most of the freezing issues especially those that result to phones that won’t respond anymore are due to a firmware crash. It can be addressed by doing the Forced Reboot and it might be the only thing you need to do to make your Galaxy J7 Pro respond again. Here’s how you do that:

  • Press and hold the volume down and power keys together for 10 seconds or more.

If your phone boots up after doing this, then you can consider the problem as fixed at this point. After all, the main problem here is that your phone is not responding. However, if it won’t respond to this, try doing the same procedure a couple more times or you may try this:

  1. Press and hold the volume down button and don’t let go of it.
  2. Then, press and hold the Power key while holding down the volume down button.
  3. Keep both keys held down together for 10 seconds or more.

It’s basically similar to the first one only that we’re making sure the power key is pressed and held after the volume down button because doing otherwise won’t give you the same result. If the phone is still not responding after this, then you should try the next solution.

Second solution: Charge your phone and do the forced reboot

It’s possible your device ran out of battery. The thing is that if the phone loses power all of the sudden, some of its hardware components and services may not be shutdown properly and that may lead to a system crash. We already know that if the firmware crashes, your phone no longer responds not add the empty battery to the equation and you will have a more serious issue. But you can fix that by doing this:

  1. Plug the charger to a working AC outlet.
  2. Using the original data/power cable, connect your phone to its charger.
  3. Regardless whether your J7 Pro shows the charging signs or not, leave it connected to its charger for at least 10 minutes.
  4. Press and hold the volume down button and don’t let go of it.
  5. Then, press and hold the Power key while holding down the volume down button.
  6. Keep both keys held down together for 10 seconds or more.

After doing this and your phone is still frozen or unresponsive, try booting it up in recovery mode because even if it has a serious firmware issue, it may still be able to boot into the Android system recovery menu. If successful, you can then proceed with a master reset and here’s how you do that:

  1. Turn off your Galaxy J7 Pro.
  2. Press and hold the Volume Up button and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. 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).
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If all else fails, then you should bring the device to the store or shop so that a technician can check it for you.

How to fix Samsung Galaxy J7 Pro that won’t turn on (easy steps)

The Samsung Galaxy J7 Pro has a huge battery but it would be useless if the phone won’t turn on. Such is the case with some of our readers who reported that their phones just turned off one day and would no longer turn on regardless how many times they hit the Power key. In other words, the phone is unresponsive with its black screen. When connected to its charger, it won’t charge and won’t even recognize the fact that it’s connected to the charger.

This isn’t the first time we’ve encountered this problem. In fact, even Samsung’s flagship phones also have a problem like this. It might be just an issue with the firmware or it could be a sign of a more serious problem. The purpose of this post is to find out which is which and of course, we’ll try to fix the problem. So, if you’re one of the owners of the Galaxy J7 Pro and are currently having similar issues, then continue reading as this articles may be able to help you.

Before we proceed, if you’re looking for a solution to a problem with your phone, try to browse through our troubleshooting pages to see if we support your device. If your phone is in the list of our supported devices, then go to the troubleshooting page and look for similar problems. Feel free to use our solutions and workarounds. Don’t worry it’s free.

Solution to Galaxy J7 Pro that won’t turn on

More often than not, this problem is basically just a result of a system crash provided that it started on its own without apparent reason or cause. However, if the phone got dropped on a hard surface or if it got in contact with water and then this problem started, it’s a clear indication that the problem is caused by physical and / or liquid damage. In such case, you should bring the phone immediately to the service center without doing any troubleshooting procedures.

But in this troubleshooting guide, let’s assume the problem isn’t due to physical or liquid damage. Here’s what you should do…

The Effective Solution

Press and hold the Volume Down button and the Power key simultaneously for 10 seconds or more. This would boot the phone up normally as it simulates battery disconnect and refreshes the devices memory. It’s a simple procedure but it’s very effective in dealing with system crashes or other minor firmware issues.

If your J7 Pro still won’t respond to this, then you should try doing this…

  1. Press and hold the Volume Down button first and don’t let it go.
  2. Press and hold the Power key while holding down the Volume Down button.
  3. Keep both keys held down for 10 seconds or more.

It basically has the same effect as the procedure above but this time, we’re simply trying to make sure you’re doing the combination correctly. Pressing the Power key first isn’t the same as pressing the Volume Down button first. When doing a combination, it would be better to press the Power key last.

Now, if the phone is still not responding after this, there’s another thing you could do to try and bring the phone to boot up. It’s possible that the battery has just been completely drained that’s why it doesn’t respond no matter what. To address that, here’s what you should do:

  1. Plug the charger to a working AC or wall outlet.
  2. Using the original cable, connect  your phone to its charger.
  3. Regardless whether the phone responds or not, allow the phone to charge for at least ten minutes.
  4. Now, press and hold the Volume Down and the Power keys simultaneously for 10 seconds again.

If the battery is drained, the phone should respond after doing this procedure. However, if the issue continues and you’re sure you’re doing everything right, then it’s time to bring the phone to the service center so that a technician can take a look at it and do some tests.

How to fix your Samsung Galaxy J7 Pro that keeps freezing and lagging (easy steps)

Performance issues like freezing and lagging are among the most common problems you may encounter after several months of using your phone. It may have something to do with the storage left in your phone’s memory or the number of apps running in the background. In the case of some Samsung Galaxy J7 Pro owners, their phones reportedly started to freeze and lag after an update which leaves an impression that it could be a firmware issue.

The Galaxy J7 Pro was released with Android 7.0 Nougat already running and Google is yet to make Android 8.0 Oreo available for public in the coming weeks or months. So any updates that were rolled out of this device should have all been small ones.

With that said, if this problem started after an update, then there’s a possibility that it’s due to some corrupt system caches and/or data files. Naturally, such problem is easy to fix and you don’t need a technician to make your phone run smoothly again. So, in this post, I will share with you a simple trick to make your device run smoother like before without those freezes and lags. So, if you’re one of the owners of the J7 Pro, continue reading as this post may be able to help you.

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 get rid of freezes and lags on Galaxy J7 Pro

Performance issues are often firmware-related and if they started after an update, there’s one solution that I know would work. Well, at least, it worked to many of our readers who have encountered similar issues in the past.

Wipe cache partition to fix freezes and lags on Galaxy J7 Pro

That’s right, you need to wipe the cache partition of your phone to delete all system caches and be replaced with new ones. There are times when caches get corrupted and it happens more often during firmware updates. Here’s how you do it:

  1. Turn off your Galaxy J7 Pro.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

After this procedure, use your phone to know if the freezes and lags disappeared. If there are still occasional occurrences, then you have no other choice but to do the next solution.

Backup your files and data then reset your phone

A reset will fix this issue but the reason why it always comes at the end of almost all of our troubleshooting guides is because it’s a hassle to backup files and data. Depending on how much data you need to backup, it may take an hour or two before you can transfer everything you don’t want to lose to your computer. But you have no other choice at this point so if you want to get rid of the freezes and lags, then take time backing up your files and then disable the Factory Reset Protection by removing your Google account from your phone so that you won’t be locked out after the reset. Once everything is set, follow these steps to reset your phone:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

I hope that our solution will work for you. If there are other things you want to share with us, leave a comment below.

How to fix Samsung Galaxy J7 Pro screen flickering problem (easy steps)

Display issues in mobile devices like screen flickering can be due to hardware damage or software glitches. In most cases though, the problem is tied to software errors like when bad updates are installed, corrupted video apps and files are opened. Other than that, a damaged display component must be the culprit. But before rushing to a service center, you still can try some workarounds and attempt to fix the problem on your end. Listed below are a few helpful solutions you can refer to if ever you need more inputs on what to do when you’ll encounter a similar display problem on screen flickering with your Galaxy J7 Pro device.

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.

Potential solutions to screen flickering issues affecting Galaxy J7 Pro

The methods I’ve demonstrated here are standard procedures to troubleshoot various types of display issues that are attributed to software errors on the Galaxy J7 Pro handset. These can be regarded as potential solutions for as long as no damage to any of the phone’s physical components is present. Start whenever you’re ready.

First solution: Restart or forced restart.

Many software glitches like random apps crashes, lags, and freezes are usually dealt with by a restart, if not a forced restart. It’s the simplest way to refresh your device. A restart can also help clear up your phone’s internal memory. If the problem persists after the first reboot, then give it another try. It could take more device restarts for some glitches to be rid off completely.

Hence if it occurs all of a sudden for your device screen to flicker, then it might just be a random glitch which requires a reboot to be rectified.

To do so, press the Power key until the Power menu pops up then touch Power off. Wait for about 30 seconds and then press the Power key again to reboot your device.

For devices that flickers and unresponsive to touch inputs, you can do a forced restart instead.

Just press and hold the Power key and the Volume down key simultaneously for about 10 seconds or until the device power cycles.

Second solution: Turn off hardware overlays from the Developers option.

Some cases of flickering displays experienced by Galaxy J7 Pro owners were tied to a pertinent setting called screen overlay that’s enabled on the device. To make sure this is not the trigger, try to turn this feature off then see if it gives any difference. Here’s how to disable screen overlay for all apps on your Galaxy J7 Pro device:

  1. Tap Settings from menu.
  2. Tap Apps or Application.
  3. Select Application Manager.
  4. Click MORE on the upper right corner of the screen.
  5. Tap on Apps that can appear on top.
  6. Tap More again.
  7. Select Show System Apps.
  8. Tap the app switches to turn off screen overlay of all apps one by one.

Third solution: Boot your Galaxy J7 Pro into safe mode.

Booting into safe mode can help rule out the possibility of a third-party app causing the screen to flicker. All third-party apps and services are bypassed or temporarily disabled in safe mode so it’ll be easier for you to isolate the problem. Here’s how to enter safe mode on your Galaxy J7 Pro:

  1. Turn off your phone.
  2. Then press the Power key for a few seconds. When the Samsung logo appears, press and hold the Volume Down key until the phone boots up.
  3. You should see Safe Mode at the bottom left corner of the Home screen.

If the screen flickering or dead pixels don’t appear while using your device in safe mode, it means that a third-party apps is culprit. Uninstall the suspected app(s), probably the most recent app you’ve downloaded or installed on the phone.

If the screen flickering problem persists while in safe mode, continue to troubleshoot your phone system. It’s like more complex software issue that needs to be dealt with.

Fourth solution: Clear system cache and data through Galaxy J7 Pro recovery mode.

Wiping the cache partition can help fix the problem if it’s triggered by some bad files segments or corrupted cache files in the phone system registry. Here’s how to wipe the cache partition on your Samsung Galaxy J7 Pro:

  1. Turn off your phone.
  2. Press and hold the Volume Up and Home keys simultaneously then press the Power key.
  3. When the Android logo appears, release all buttons at once then wait a few seconds for the Android System Recovery screen to appear.
  4. When prompted with the Recovery menu, press the Volume Down key repeatedly to highlight wipe data/factory reset.
  5. Then press the Power key to confirm selection.
  6. Press the Volume Down key to highlight wipe cache partition and then press the Power key to confirm.
  7. Press the Volume Down key to highlight Yes and press Power again to confirm.
  8. Wait until the cache partition is cleared. When the Reboot system now option is highlighted, press the Power key to reboot your device.

Fifth solution: Master reset or reset your Galaxy J7 Pro to factory defaults.

A master reset or factory reset can be considered as last resort if the screen flickering issue continues after doing all prior procedures including wipe cache partition. The problem might be too intricate that requires a full system reset. A factory reset will wipe every data from your phone including your personal information. That said, back up your data then proceed with a master reset.

  1. Power off your device.
  2. While it’s off, press and hold the Volume Up, Home, and Power keys simultaneously for about 10 to 20 seconds.
  3. When the Samsung logo appears, release the Power button but keep pressing the Volume Up and Home keys.
  4. When the Android logo appears, release the remaining buttons.
  5. While on the Android recovery mode screen, press the Volume Down key to highlight wipe data/factory reset and then press the Power key to confirm.
  6. Press the Volume Down key to select Yes — delete all user data and then press the Power key to confirm.
  7. Wait for your device to hard reset. When the reset is complete, the Reboot system now option is highlighted.
  8. Press the Power key to reboot your phone.

See if that fixes the screen flickering problem on your Galaxy J7 Pro.

Opt for service or hardware damage repair

If none of the above methods worked and that your Galaxy J7 Pro is still showing a flickering display, take your phone to an authorized Samsung service center and have it diagnosed by a technician. There’s a higher chance that your phone is having some sort of physical or liquid damage on any of its display components that requires physical repair or screen replacement.

How to fix a Samsung Galaxy J7 Pro 2019 smartphone that doesn’t detect SIM card, No SIM card error [Troubleshooting Guide]

SIM card errors in mobile devices may occur due to many factors involving software and hardware components. Among the underlying causes are network problems, account-related issues, errant apps, software glitches, faulty updates, and sometimes, invalid or defective SIM card in use. Before taking your device to a service center or getting a new SIM card replacement, performing the basic troubleshooting procedures is recommended to rule out software issues out from the underlying causes.

Highlighted below are some potential solutions to a relevant issue on the new Samsung Galaxy J7 Pro (2018) smartphone, which failed to detect SIM card and shows a No SIM card error. Read further to find out what methods to try on should to clear software problems that might have prevented the phone from recognizing the SIM card.

For those who are looking for a solution to a different problem, drop by our troubleshooting page for we have already addressed some of the most common issues with this phone. Browse through the page to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you or if you still need our help, contact us anytime through our Android issues questionnaire.

First solution: Reboot your phone (soft reset).

If the SIM card works with your phone since the first time you use it, then it’s likely just a random software glitch that’s rectifiable by a soft reset or device restart. The process does not affect saved data on the internal memory and therefore won’t result to data loss. Here’s how a soft reset is done on your Galaxy J7 Pro (2018) smartphone:

  1. Press and hold the Power button for a few seconds or until the menu appears.
  2. Select Power Off option then tap OK.
  3. After 30 seconds, press and hold the Power button again to turn your phone back on.

A soft reset is the simplest solution to various types of software-related errors including those affecting the SIM card system of the phone. It’s also an effective way of dumping cached files from the internal memory.

Second solution: Remove and reseat the SIM card.

When your phone keeps prompting a No SIM card error, it’s likely telling you that truth that the SIM card is not properly secured or dislodged from the tray. To make sure this isn’t what’s troubling your device from recognizing the SIM card, follow these steps to remove and reseat the SIM card on your Galaxy J7 Pro (2018) smartphone:

  1. Power off your phone completely.
  2. Insert the ejection pin into the hole on the SIM card tray to loosen the tray. Make sure the ejection pin is perpendicular to the hole to prevent damaging the tray.
  3. Gently pull out the tray from the slot.
  4. Remove the SIM card then examine it for any visible signs of damage like scratches or dents. Also make sure that you are using a nano SIM card, otherwise you’re using the wrong SIM card type. If everything looks good to you, then place it back into tray with the gold contacts facing downwards.
  5. Gently press the SIM card into the tray to secure it, and prevent it from falling out of the tray.
  6. Insert the tray back into the tray slot when the SIM card is secured.

Once the SIM card tray is secured and locked in place, turn on your phone and see if the error is gone. If it persists, then you may have to resort to software resets.

Third solution: Reset network settings on your Galaxy J7 Pro 2018.

Network errors due to invalid settings or incorrect network options enabled on the phone can also trigger relevant errors to occur. This is likely the case if the phone suddenly bumps into a No SIM card error after installing a new software update. The update might have automatically altered or overridden the current network settings on the phone and thereby results to this error. To clear this out, performing a network settings reset is recommended. This will clear the current network settings on your phone and restore the defaults. After the reset, you can configure and enable necessary features and network options accordingly. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Scroll to and tap General management.
  3. Scroll to and tap Reset.
  4. Tap to select Reset Network Settings option.
  5. Tap Reset Settings then tap Reset Settings again on the following screen to confirm.

Restart your device as soon as the reset is finished. After the restart, you can proceed with the network setup and reconnect to Wi-Fi and cellular network.

Fourth solution: Update phone software to the latest version available.

Installing the latest software version available for your phone can also be the key to resolving the issue if it’s triggered by some malicious software or bugs. New updates usually offer security patches to clear bugs and malware that caused troubles to a device. To check for new software update on your Galaxy J7 Pro (2018) smartphone, refer to these steps:

  1. Swipe up from the bottom of the Home screen.
  2. Tap Settings.
  3. Scroll to and tap Software update.
  4. Select the option to Download updates manually. Your device will then search for new update.
  5. When the search is finished, you should see a notification telling you if a new software version is available or your phone is up to date.

If an update is available, back up all your important data for safekeeping and then follow the onscreen instructions to download and install the update on your device. To ensure all system changes from the new update are properly implemented, reboot your phone when the update installation is complete.

Fifth solution: Reset phone to factory defaults (master reset).

If none of the prior methods is able to offer a resolution and that your Galaxy J7 Pro (2018) smartphone is still unable to detect the SIM card and the No SIM card error still shows, then you may have to consider performing a master reset or full system reset. This will wipe everything from your device including your settings, downloaded apps, and other personal information. Tough bugs and malware that might have halted the phone system from reading the SIM card will also be obliterated in the process. After the reset, your device will be restored to its factory defaults or original state. Should you wish to proceed, back up all your critical data then follow these steps to factory reset your Galaxy J7 Pro via settings menu:

  1. Tap Settings from the Main Apps screen.
  2. Scroll to and tap General Management.
  3. Scroll to and tap Reset.
  4. Select Factory data reset from the reset options.
  5. Tap Reset to continue.
  6. Then tap Delete All to confirm reset.

Your device will reboot automatically when the reset is finished. After the restart you can proceed with the initial setup process and set up your device as new. Any prior software errors and glitches should be cleared by the reset. That said, your phone should be able to detect the SIM card at this point, unless the SIM card is defective or hardware damage is present.

Other options

Contact your network service provider or carrier for other options and suggestions if the No SIM card error persists and your Galaxy J7 Pro 2018 smartphone still doesn’t recognize your SIM card. If necessary, you can request for a new SIM card replacement and have your carrier active your SIM card services.

Problem: Galaxy J7 Pro screen stopped working after charging (black screen issue)

I was using my J7 pro on tuesday night… it was already at 2% charging, but i still used it to play youtube videos of lullabies for 2hours to sleep.. it was charging the whole night but youtube was left playing. so i guess it was drained, so i charged it more in themorning and in the afternoon. but still it wont turn on.. it doesnt even display an icon of charging, JUST BLACK SCREEN. i tried doing those pressing the keys,like volume down and power button and etc but it only VIBRATES AND BLINK, Just nothing worked.. I tried to call mynumber but my phone doesnt ring, but when i tried to swipe the screen in attempt to answer it, surprisimgly I can answer the calland i can talk and hear my voice clearly.. so i stopped charging it because its already working on but DISPLAYS NOTHING. It even rings shortly during the alarm time in the morning.. please help me, thank you!

Solution: There may be an app or  software bug that prevents the screen from working normally. To see if that’s the case, follow our suggestions below.

Boot to Safe Mode

This should be the first troubleshooting step that you want to do. While on safe mode, your device will suspend downloaded apps and only allow those that came pre-installed with the operating system. To restart your J7 Pro to safe mode:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Safe Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before continuing.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

If the screen works on safe mode but not when restarted to normal mode, you can bet a bad app is the culprit. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your J7 is still problematic, repeat steps 1-4.

If the screen remains black after attempting the steps above, try to see if works on Recovery Mode or Download Mode.

Restart the phone to alternate boot modes

There are two other software environments that work independently of Android — Recovery Mode and Download Mode. Either of them does not depend on Android OS to work properly so they’re used by technicians to troubleshoot devices they suspect has software issues. If the bug that causes black screen issue on your phone is due to an Android issue, the screen should work fine on either Recovery Mode or Download Mode.

How to boot a Galaxy S9 to Recovery Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

If the screen works on Recovery Mode, you can try to wipe the cache partition or do factory reset.

How to boot a Galaxy S9 to Download Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Down key and the Bixby key, then press and hold the Power key.
  3. You’ll know if you’re on Download Mode when you see a screen that says “Downloading….”
  4. Remember, if the screen works in any of these modes, that’s a clear sign that you have an Android OS issue. Be sure to factory reset the device in Recovery Mode to fix it.

If the screen only works on Download Mode, there may be an issue with Android. In this case, you can try to reflash the stock firmware to fix the issue. Use Google to know how to do this solution.

If you are unable to make the screen to work after attempting all the suggestions above, you should allow a professional check the screen. There must be a deeper reason for the problem so repair is a needed.

Galaxy J7 Pro freezes and becomes unresponsive after an update

In today’s troubleshooting episode for the Galaxy J7 Pro, learn what to do if your device freezes or becomes unresponsive during or after an update.

Before we proceed, we want to remind you that 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. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem: Galaxy J7 Pro freezes and becomes unresponsive after an update

My Samsung J7 Pro did an update and now it’s frozen. I have tried everything you suggested but it doesn’t work. I have tried volume down and power button, I’ve tried volume down, power and home button. Nothing works. Can you suggest anything else? I plugged it into power to charge it because it got down to 38% but still didn’t work.

Solution: Android devices usually encounter problems during an update if the installation is interrupted. Interruption can be due to a user intentionally turning off the device, or the system turning off for lack of battery.  

Do not power down when updating

Sometimes, system updates can take a long time to complete making the appearance that the system have become unresponsive. As an end user, all you need to do in this case is simple: wait. This is the main reason why Samsung devices allow a user to pick an option to let system update be performed overnight. Restarting an updating Galaxy device is a sure way to bricking the software and sometimes, causing permanent corruption in the device’s internal storage device.

If your Galaxy J7 Pro turned off during an update because its battery runs out, this can be another reason for the problem right now. Just like when you intentionally turn off the device, letting a device shut down in the middle of an installation can be a death sentence. This is the reason why you must ensure that there’s at least 80% battery before you start an update. Better still, only update the system when it’s plugged in to the charger. Doing so will lessen the chance of the device turning off in the middle of the installation.

What to do if J7 Pro freezes and becomes unresponsive after an update

If any of the above scenarios happen on the device while it’s updating, there are two things that you can do:

  • perform a master reset
  • reflash the stock firmware

Master reset is factory reset using a combination of hardware buttons. Here’s how it’s done:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If nothing works after a master reset, or if you are unable to boot the phone to Recovery Mode at all, you should consider flashing stock firmware via Download Mode. Flashing procedures vary by phone models and is not guaranteed to work in all cases. Use Google to find a good flashing guide for your device.

Get Samsung support

Should master reset nor flashing won’t help, contact Samsung for help. The least that can happen now is repair (if there’s any hardware issue) so make sure to talk to a Samsung tech for other options. If the phone is still under warranty, repair of this type (as long as they can’t find traces of you tampering with hardware and software) will be free. If your S9 is no longer warranty protected, repair or replacement will cost you at least about $200 depending on your case.

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.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start.

Problem #1: Galaxy J7 Pro sound is low when using headphone

Hi! I’m using Samsung J7 Pro and my problem is that when I connect an Headphone even the volume is Max I hear low volume of music.. I tried different types of Headphones and even try to Reset my phone but still the issue remains. These issue started when I plug-in my device in my speaker using my headset jack and my speaker just have an short circuit and blows out and when that accident happened my phone is still in connect with the speaker. Is there any solution to this? Thank you.

Solution: As an end user, there’s only so much that you can do. In this situation, the most that you can try is to factory reset the device. This should help you check if the reason for the problem is fixable on your level. Since you’ve already tried that without any positive change, you can only assume that there must be a hardware malfunction. If you want to see if the problem can be fixed without having to replace the motherboard, let a professional check the hardware. If the device is still covered by Samsung warranty, you can also bring it to Samsung so they can repair or replace it.

Problem #2: How to create a backup if Galaxy J7 Prime keeps freezing after an update

I have a Galaxy J7 Prime. In mid-April 2018 I have carried out a software update as requested by Android but after that, the phone seems to suffer from freezing or system UI problems. After restart, the phone will only be controllable for a few minutes then it freezes. If I need to backup my files and data, would this be safe to do under this conditions when the mobile phone keeps freezing? Will the backup processes be affected by the freezing? I have a fairly recent back up file so if this backup process could result in corruption of the backup files, I may just forget about the latest data and just use the backup files I currently have. What would you recommend? Many thanks for your very helpful posts.

Solution: When creating a backup, the phone has to perform normally as expected so if the slow performance issue affects the general functions, it’s possible that freezing may still occur. The best way to find out is to create backups without putting too much pressure on the system. Here’s what you can do:

  1. Install Samsung Smart Switch to your computer and phone.
  2. On your Galaxy J7 Prime, close all running apps via Recent Apps key (left button next to the Home button).
  3. Optimize device by going under Settings > Device maintenance > Performance mode > select Optimized (recommended) option.
  4. Connect the phone to your computer via USB cable.
  5. Create a backup of your files by batches or by type. For instance, try backing up photos only, and in small number only.

Remember, you want to put as little pressure to the system as much as possible. Avoid moving huge number of files at the same time.

If the steps above won’t work and the phone continues to freeze, do a factory reset. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Problem #3: How to fix a Galaxy J7 Pro with Google apps freezing and crashing

Hi. Good day. My phone is a Sam J7 Pro (SMJ730G/DS) and I am having problem with the unit. Suddenly it started to delete apps automatically (Google Maps, Play Music etc.), sometimes it freezes then restarts automatically, and a lot of Samsung and Google apps are stopping in the background giving me dialog boxes saying system keeps on stopping. They say its a board problem but how come I can use other applications like calling and sms although sometimes it still restarts? Thank you.

Solution: Well, first of all, you should have provided us with your phone’s history or background. Freezing issue don’t happen for a reason. There may be a software or background issue causing it.

Secondly, if Google apps seem to be the most affected by freezing or crashing issue, there may be a Google-account issue behind the problem. Below are the troubleshooting steps that you can try to fix it:

Clear the cache partition

Updates or app installations may sometimes corrupt the system cache in the cache partition. To ensure that this cache is in good shape, try clearing the cache partition with these steps:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. 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).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Delete Google Services Framework data

One of the most effective ways to fix Google-related bugs in an Android device is to clear the data of its major core app — Google Services Framework. If you haven’t tried doing it, here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find Google Services Framework and tap it.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your device and check for the problem.

Reset all settings

This procedure is separate from the previous one as it covers all settings of your Android device and not just the apps. To do this, follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Factory reset

The easiest way to fix issues with your Google account or its services or apps is factory reset. If the cause of the freezing problem is an unknown operating system, factory reset may also help. Refer to the steps above on how to factory reset your J7.

Problem #4: How to unblock a Galaxy J7 with FRP lock

Hi. I thought my phone hang up and didn’t open, it says “Custom Binary Blocked by FRP” at the upper left corner. What should I do to make it work again? I tried the suggestion from YouTube and other online site but to no avail since I can’t figure out how to download the firmware and the Odin as suggested in YouTube. Is it okay if you can give me the link so I can easily download it? hank you I will really appreciate it if you can respond to me promptly.

Solution: There are two ways to unblock a device that becomes unusable due to Factory Reset Protection (FRP). One is by entering the correct Google account username and password. This Google account should be the one that was added to the device before it was factory reset.

If you’ve already tried the first solution but the phone remains locked, then you should do the second option, which is to seek help from Samsung. Be sure to bring the receipt (proof of purchase) and a valid identification card. Samsung can use a special tool to bypass FRP for you.

Problem #5: How to fix Galaxy J7 voice calling issue: sound is garbled and other party can’t hear

Whether I initiate the call or the call is inbound to me, the same issue.  The other side says my voice is garbled, or sounds like a roar in the background, etc. They can’t hear or understand what I say.  This only started happening recently. I can play music in the car via BT, use google maps via the car audio no problem. This is a stock BT system, 2013 Honda CR-V. I’ve unpaired and back, no improvement.  How can I tell if the problem is my phone or the Honda BT system? Thanks.

Solution: There’s a number of factors that can affect voice calling quality. In your situation, try to narrow down the possibilities by removing them one by one. For instance, to know if the problem is due to your car’s Bluetooth system or not, you can disconnect the phone from it and try calling normally (without any Bluetooth device attached).

If the issue continues even without any Bluetooth gadget, you can then move on to checking if it’s an app issue or not. To do that, you can try to clear the cache and data of your Phone app. Or, you can use another Phone app to make calls.

To check if there’s any software or operating system bug causing the problem, factory reset may be necessary. Be sure to check the steps above if you have no idea how to do it. Don’t forget to back your files up before wiping the phone.

Voice calling quality also depends on your network operator’s system. Sometimes, their network may suffer from glitches or malfunction. If nothing will change after you factory reset your phone, be sure to talk to them for help.

How to fix Galaxy J7 Pro texting issue: keeps showing “Not registered on Network” error, texting and calling not working

Many #GalaxyJ7 and #GalaxyJ7Pro users are contacting us for solutions everyday so today’s post will answer some of them. We hope you’ll find the solutions fix your own issue.

Before we proceed, we want to remind you that 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. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix Galaxy J7 Pro texting issue: keeps showing “Not registered on Network”  error, texting and calling not working

I have Samsung J7 Pro and been a week since it kept saying “Not registered on Network” when i tried to call and message, but it allows me to use only internet. I tried to search  network manual, i tried to set the network APN and select it, i reset my phone to factory mode, i take out the sim and insert it and each time it’s the same. P.S the sim works with other phone. 

Solution: When you say internet is working, are you using cellular or mobile data connection or wifi? If the internet connection you are referring to is wifi only, that means that may be a problem with device’s network function.

If, on the other hand, mobile data is working but not the text messaging and calling functions, there may be an app blocking these missing capabilities. Try to restart the phone to safe mode and check for the problem. In safe mode, all third party apps will be suspended so if everything works normally, that’s a clear sign of an app trouble.

These are the steps to restart your phone to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Check for the problem.

If you J7 Pro can send and receive texts and can call, one of the installed third party apps is to blame. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your J7 Pro is still problematic, repeat steps 1-4.

If there’s no change in safe mode though, the best people that can help is your carrier’s technical support team. They have access to your account details and history and if the phone came from them, it’s history too. Make sure to provide all the necessary information to them especially the things that you did differently before noticing the trouble.

Problem #2: Galaxy J7 keeps showing no mobile network available, signal keeps disappearing

Galaxy J7 won’t reconnect to 3G or 4G. After leaving Wi-Fi range says no mobile network available, but there is mobile network available. Sometimes there are 4 bars showing but it still says no mobile network available. usually a restart helps Cannot text over Wi-Fi. I have done the reset where i press the volume down button and the power button to simulate a battery removal several times.

Solution: There may be a network bug causing this problem so the first troubleshooting step to try is clearing the device’s network settings. Here’s how:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your J7 and check for the problem.

Sometimes, clearing a device’s system cache may also help in fixing network troubles. Be sure to do it after wiping the network settings. Follow these steps to do that:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. 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).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Problem #3: Galaxy J7 won’t boot up after failed update

I have a problem with my Samsung Galaxy J7. I tried to update. After the update installed, it’s stuck on the Samsung logo. I tried the following to no avail: Turn off the device. Press and hold the following three buttons at the same time:Volume Up key, Home key, 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 data / factory reset.’ Press Power button to select. Press the Volume down key to highlight ‘delete all user data.’ 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 turn the restart the device. what can I do?

Solution: If this trouble started after you tried to update normally, that is, via your carrier’s network (OTA), then you need to contact your carrier’s technical support team so they can assist you. In doing so, you are letting them know of the problem (so they can track it and do something about it) and getting official assistance.

On the other hand, if the problem started after you tried to manually install the update via flashing, you should consider flashing back the previous firmware (stock).

Problem #4: What to do if your Galaxy J7 is hacked

My issue may be too personal to be online, do you respond by email only? I’ve been hacked for over a year. Ive been thru 10+ phones, changed emails, phone numbers, etc. My J7 is cloned, only picks up femtocell networks, does what it wants, records audio, video, sends messages, makes calls. I was in a previous abusive relationship and my phone always stores files or my emails, website pop ups pertain to the torment i suffered. It’s a cruel, sick individual. I cant get any help and i dont even know if this will reach you. If you can email me i would greatly appreciate it if not i understand. Thank you.

Solution: If all phones you got end up getting hacked all the time and there’s been domestic abuse involved already, we’re not the ideal party to seek help from. In this situation, you should involve your local law enforcement people in fixing it as there’s obviously nothing that you can do on your end to help yourself. The person doing the abuses to you must be using sophisticated technology to access your new device and penetrate its defenses. We’re here for simple day-to-day Android troubleshooting. We are not equipped to investigate how hacks happen on your devices. Unauthorized device access is almost always a crime in all countries nowadays so you must let the authorities help you in this matter.

Problem #5: Galaxy J7 won’t turn on

Samsung J7. I decided I did not want the 4 digit security pin to open my phone anymore. So I went into security and changed pin to NONE. It was fine – until I charged it (switched off screen)- about an hour later. This morning when I try to switch it on it is dead black screen. I followed your volume/power key instructions but does not work. I have put it on charge and tried volume/power key – does not work. When on charge now it shows a circle with small charge signal in middle of circle. But wont turn on…. Please help – must have something to do with removing security opening pin…? I am not sure what android system it operates on..have put jellybean…but dont know.. Thank you.

Solution: We can’t see the logic of changing the screen unlock option causing your phone to not turn on afterwards. It may just be a coincidence and there may already be a possible underlying reason why your device no longer powers on at this time. Try charging the device using another set of accessories. There may be an issue with the cable or adapter you’re using to charge the phone right now. If that won’t help, try to follow our other suggestions in this post.

If the network is good but you still cannot send or receive SMS or text messages on your Galaxy J7 Pro 2018 smartphone, then try the following simple solutions.

First solution: Force close messaging app then restart.

Errant apps are usually remedied by forcing it to close. The app may be glitching and is therefore unable to function. In that case, you’ll need to force close it then restart. Here’s how:

  1. Tap the Recent Apps icon on the bottom left corner of the phone.
  2. Scroll to and select the messaging app from the app previews.

  1. Swipe up or down to open the Apps menu from the Home screen.
  2. Tap the Play Store icon.
  3. Tap the Menu icon or three-horizontal lines on the upper-left corner of the Play Store main screen.
  4. Tap My apps & games.
  5. Go to the Updates tab to view a list of apps with pending updates.
  6. To install an update, select the app then follow the onscreen instructions.

If you don’t see your messaging app in the list, it means there’s no new update for that app yet.

Return to the Home screen then restart your device to refresh the system and apply the software changes.

If you’re using the stock messaging app, then try to check for new software version/update available on your phone. Aside from new features and functionalities, the latest Android version also brings in security enhancements to keep Samsung devices as bug-free as possible. To check for new Android update on your Galaxy J7 Pro 2018, follow these steps:

  1. Swipe up from the bottom of the Home screen.
  2. Tap Settings.
  3. Scroll to and tap Software update.
  4. Select the option to Download updates manually. Your device will then search for new update.
  5. When the search is finished, you should see a notification telling you if a new software version is available or your phone is up to date.

The new update will then be implemented on all your system apps and services. Restart your device and then check and see if SMS services are now working as intended.

Fifth solution: Change/set the default messaging app on your phone.

If none of that works and the problem continues, try to switch to other messaging applications. If you’re on stock messaging app, try other credible platforms like Telstra. To make sure it works, be sure to set the default SMS app to use on your Galaxy J7 Pro 2018 smartphone. Here’s what you should do then:

  1. Download the preferred SMS app to use as alternative.
  2. Then swipe down on the notification panel of your phone.
  3. Tap the Settings menu represented by a cog icon.
  4. Tap Apps.
  5. Tap the three-dot icon on the upper right of the screen.
  6. Tap on Default apps.
  7. Then tap Messaging apps.
  8. Select the SMS app you want to switch to.
  9. Tap OK to confirm change on the default messaging app.

Reboot your device then open the new SMS app and then try to create a sample SMS message to send and receive. If the problem is fixed then that’s an issue with the stock messaging app that needs to be resolved by Samsung. In that case, contact Samsung Support to escalate the problem for official recommendations.

Other options

Contacting your service provider/carrier is also important to check the current status of your account and outgoing services. Carriers would usually impose a soft disconnect to accounts with unsettled issues/bills. When this happens, outgoing services including text messaging are temporarily disabled. As a result, you won’t be able to send text messages or make phone calls on your device. Make sure that’s not causing you this trouble.

How to fix Galaxy J7 Pro with Messenger that keeps crashing


The following are the most effective solutions to app-related problems you may encounter with your Galaxy J7 Pro…

First Solution: Reboot your phone

There’s more to reboot than just turning your phone off and back on again. It also refreshes your phone’s memory, closes all apps and services running in the background as well as reloads all core services and functions. You need to do this procedure because there’s a possibility that the problem is due to a minor glitch in the system or the app itself. It’s easy and safe to do, not to mention very effective. So, hit that Power key and reboot your phone.

After the reboot, open Messenger to know if it still crashes. If it does, then try doing the Forced Reboot procedure. It ‘power-shocks’ your phone and it simulates battery disconnect. During this sequence, electricity stored in capacitors are drained so your phone’s memory will be reset without deleting any of your data. To do this, press and hold the Volume Down button and the Power key at the same time for 10 seconds or more. Your phone may reboot normally and after which, try to use Messenger. If the problem continues, then move on to the next solution.

Second Solution: Reset Messenger

By reset, I mean clearing its cache and data. It will bring the app back to its default settings and it’s cache and some data files will be replaced with new ones. These processes will be done in the background and automatically so you don’t have to worry about it. All you need to do is follow these steps to reset Messenger:

  1. From a Home screen, touch and swipe up or down to display all apps.
  2. From a Home screen, navigate: Settings > Apps.
  3. Tap App Manager.
  4. Locate then tap Messenger.
  5. Tap Storage.
  6. Tap CLEAR CACHE.
  7. Tap Cached data.
  8. Tap CLEAR.

I know it’s a very simple procedure but it’s very effective in dealing with this specific problem. In fact, it might be the last thing you need to do about this issue. However, if by any chance the app still crashes after doing this, then move on to the next procedure.

Third Solution: Uninstall / reinstall Messenger

You do this instead of updating the app. When you update Messenger, you’re only replacing some files. It’s effective but not as effective as when you uninstall the app and reinstall it. By uninstalling, you will delete all the files created by the app itself as well as ones created by the system for the app. Aside from that, all its associations to some apps, services and features will also be removed. Here’s how you uninstall Messenger from  your Galaxy J7 Pro:

  1. From a Home screen, touch and swipe up or down to display all apps.
  2. From a Home screen, navigate: Settings > Apps.
  3. Tap App Manager.
  4. Locate then tap Messenger.
  5. Tap UNINSTALL.
  6. Review the notification then tap OK to confirm.
  7. Reboot your phone to refresh it’s memory and other connections.

After the reboot, it’s time you reinstall Messenger. This time, you can be sure that the app that runs on your phone is the latest version.

  1. From a Home screen, touch and swipe up or down to display all apps.
  2. Tap Play Store.
  3. Type ‘messenger’ in the search box.
  4. Select Messenger then tap Install.
  5. To continue, review the required app permissions then tap Accept.

That’s it! You should be able to use the app now without being greeted by the error and/or any other issues. I hope that our solutions work for you, if you have other concerns with your phone, feel free to contact us or leave a comment below.
