Problem #1: Galaxy S7 edge not receiving text notifications

Hello. I have the Galaxy S7 edge and I stopped receiving text notifications months ago. It would vibrate, but that is it. Now with this new update nothing happens. I have missed extremely important text messages from work and family that needed to get ahold of me, but knew not to call because my baby was probably sleeping.

I also have no idea what Android version I have. I just picked one on the drop down list.–Amanda

Solution: Hi Amanda. The Android version on your phone is probably Marshmallow or Nougat so the way to customize notifications should be similar. The good thing with Marshmallow and Nougat is the fact that a user can refine what notifications from which app is received by the phone. If you haven’t tried tweaking the phone’s notification settings, here’s how to do it:

  • Open the Settings app.
  • Tap Notifications.
  • Make sure that you enable notifications for the messaging app you’re using.

Now, in the Notifications section you’ll see a list of all apps that can provide notification. If you want to simply flat out receive all types of notifications from all apps, simply turn the All apps button to the ON position. This will allow the phone to receive all notifications.

In Android Nougat, scrolling down to the bottom of Notifications section gives you three more options that to allow you to customize your phone notifications. If you want to do that, select NOTIFICATION REMINDER. Once you’ve selected it, make sure to set it to ON.

If, for some reason, notifications will still fail to work in your phone, make sure that you wipe the cache partition to refresh the system cache. Sometimes, a system cache gets corrupted after an update so keeping it up-to-date is important. A corrupted system cache can sometimes lead to all sorts of issues so it must be kept in good state all the time. Here’s how to do that:

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

If your problem remains after wiping the cache partition, do a factory reset. This will force the phone to return all software settings to their defaults. If you unintentionally changed some settings that affected the notification, or if an app caused this problem, factory reset should fix it.

To factory reset your S7, follow these steps:

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

NOTE: Factory reset will wipe everything in your phone’s internal storage device so make sure to create a backup before doing it.

Problem #2: Galaxy S7 black screen issue, won’t turn on

Hi there. Well, I woke up this morning head over to my phone finding the screen black and the green light on as to show its charged. So i unplug the charger… aaaaaaand… no change. Green light still persistently on, screen still black as night and NO force /safe mode/ recovery mode/ restart method worked… next step is i grab a hammer.. and see if just going to town on it makes me feel any better… BUT…. thought id give this mail thing a try first… any ideas.. or was my hammer one a sound one..? — Riaan

Solution: Hi Riaan. If the phone is totally dead and does not respond to any hardware button combinations to boot it to alternate modes, you have no other choice but send it in. The hardware must be checked first to know which component has failed. In a situation like this, there’s a chance that the battery may be to blame. If you’re lucky, a new replacement battery can easily fix the problem. If battery is not to blame, that can mean that there’s a serious motherboard issue that may require an expensive repair. We suggest that you send the phone to a Samsung service center as they usually offer a replacement unit for most motherboard-related problems.

Problem #3: Galaxy S7 Nougat update notification keeps showing up

I have a Samsung S7 with T-Mobile running Marshmallow. Nougat is now available, and every 5 minutes a screen comes up asking me to download it. I don’t want to, as I like Marshmallow, and I I understand that many people have 10-20% shorter battery life work Nougat. I only get 6-6 1/2 hours as it is, so I don’t want to take a chance.

Is there any way to get the T Mobile update screen to stop popping up? (I had an S5, and I installed Lollipop by hitting that screen by mistake. My phone was awful for a year until Marshmallow was available.) Thank you! — Dana

Solution: Hi Dana. In international Galaxy S7 devices, there’s an option for users to allow them to manually let the phone check for software updates. If a user opts to use Download updates manually feature, this will prevent the phone from checking for updates and showing notifications about it. This feature is found under Settings>Software update but we are not sure if this available in T-Mobile devices. Carriers often set their devices to automatically download and install system updates. If you can’t find it in your phone, T-Mobile must have removed it.

Problem #4: Galaxy S7 cannot access wifi, internet or Gmail after an update

After Samsung updates I can no longer access Wi-Fi/internet, G-mail. Screen freezes frequently when I enter a phone number to make a phone call. Then when I try to power off sometimes that will not work. Then, finally, it will power off and after reboot, then I can make the phone call. I am able to text. However, frequently the text is delayed in sending. Again, I have to power off and reboot and then, most of the time, it will resend the text. Same thing, happened two years ago, a few months ago before my contract was up. There is “SOMETHING” very odd with the Samsung updates. The cell phone should be not rendered nearly useless after updates! So very frustrating and annoying. I have never dropped the cell phone and it has never been in water!! Sincerely. — Arlene

Solution: Hi Arlene. The first thing that you want to do in this case is to wipe the messaging app’s cache and data. Hopefully, this troubleshooting step will address the bug that may be causing the text messaging issue. Here’s how to do it:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. 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.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Wipe the cache partition

Deleting an app’s cache and data can usually fix app-specific issues following an update. However, if the problem continues after doing it, you should broaden the troubleshooting to include the system cache as well. If you haven’t done it yet, make sure that you also wipe the cache partition. Refer to the steps above on how to do it.

Install app updates

Keep in mind that installing system updates does not necessarily mean apps are automatically updated too. Make sure that all your apps are compatible with the operating system and updated. Installing incompatible apps can cause instability and performance issues. It’s your responsibility to ensure that you only add compatible apps in the system.

Wipe the phone via factory reset

If all the above steps won’t help at all, make sure that you turn the phone as clean slate. Once you’ve factory reset the phone, observe it for a full 24 hours without installing any apps or updates. Doing this will help you find out if the issue is software- or hardware-related. So how would you know that it’s a hardware issue? Simple. If the problem returns during the observation period, that means that something other than a software problem is to blame.

Problem #5: Galaxy S7 sending and receiving of SMS is intermittent

Hi. My issue is that my ability to send and receive calls and texts is intermittent. Sometimes it works normally, sometimes not at all. My job depends on my employer calling me in each day if needed. Some days it works, others I get a notification of a voicemail message received hours after the call was made, and never get any notification of a call. I have sent texts to friends that say they are sent but do not get to their phone, and I have not received plenty of texts.

Additionally, when my wife texts me from her iPhone, it often delivers two copies of the same text. A while ago I dropped the phone and the GPS hasn’t worked without wifi since. Calling however hasn’t been a problem until the last few months. I’m mentioning it in case the two are related. The GPS is not intermittent, it simply doesn’t work at all. I haven’t dropped the phone in any considerable way since. Thanks for your help! — Alex

Solution: Hi Alex.  There’s a chance that the problem lies on the phone itself but to know that for sure can be challenging, especially if it’s due to hardware malfunction. If you haven’t done any troubleshooting yet, we suggest that you try all the ones we suggest for Arlene above. If you noticed, the troubleshooting steps are all geared towards narrowing down possible software issues. If you can’t fix your issues after doing all of them, you can assume that there’s either a hardware malfunction or a network issue (causing delayed notifications and erratic SMS behavior).

There’s obviously nothing that we can do about a hardware problem so if you think that’s the case, you must have the phone repaired or replaced.

To see if it’s a network-related issue, try to insert your SIM card in another phone and observe how SMS works. If the same problem occurs, contact your carrier and ask them for direct assistance.

Problem #6: Galaxy S7 left screen is not responding

Hi! My Samsung Galaxy S7 has a screen problem which is the left part of the screen is not responding properly. Sometimes when I swipe or go to some apps, it works fine. But sometimes, for example, when I swipe, the left part of the screen does not change. For example, when I go to the camera app from the home screen, the right part of the screen shows the camera but the left part still shows the home screen. But even if I can only see the home screen at the left part, I can still click through the left part, touch the settings menu which is on the left. It’s only the display that lags but the function is still working. Another example is type the password from screen off. The left part does not light up but I can touch the letters Q,W,E,A,S,D,Z,X which are all in the left part of the screen even though the screen is just black. I hope you read this message and you will respond so I can send some pictures about it. Thanks. — Genrev

Solution: Hi Genrev. Try to factory reset your phone first so you will know if this is an issue caused by a software glitch or not. If the screen continues to behave the same right after a factory reset, that’s a sign that something is not right with the screen assembly, or even the graphics chip of the phone. If your phone is still within warranty, make sure that you send it to Samsung so its hardware can be examined. There’s a chance that the problem may be isolated on the screen assembly only so a screen replacement may do the job. If it’s anything else, you may be looking at a possible motherboard replacement or phone replacement.

Problem #7: Galaxy S7 overheating, freezing, and randomly rebooting

Hi. i got a new phone that starts overheating after three weeks that I was using it. I went to the store where i bought it from and they just offer me to send it to a service that is fixing everything from microwaves to dishwashers. I didn’t do it. but now after one month I can’t even use this phone. I can’t even put my PIN because the screen get frozen. it is switching off and on, restarting, freezing every two minutes literally. Phone even burned my face as got over heated while I was just talking. I can’t get no help from Samsung as they don’t see any issues and i am very disappointed trying to fix the phone by my own. I can’t use a phone as it is not reacting. I can restart it but after a minute it is dead again. Please can you give me any suggestions. i tried safe mode and everything but nothing is working. — Kate

Solution: Hi Kate. Taken together, the symptoms you’re describing here can only mean a hardware problem. When overheating, freezing, and slow performance issues are presence all at once, it can only mean a bad hardware. Whether you like it or not, you have no choice but to return the phone to the store so it can be repaired or replaced.

Problem #8: Galaxy S7 cannot send SMS reply to one contact

Just got a new phone, was texting fine. Now one contact (that I’ve noticed) can send me messages, but when I try to reply, it puts my message into a new conversation screen, and will not send the message. It also says the contact number for my friend is not a regular 10 digit number, but tacks on an entire number to her number, giving a 20 digit number. I tried deleting her completely as a contact and re-adding her. It worked for a while and then went back to giving her a 20 digit number. — Dpowerade

Solution: Hi Dpowerade. This may be an app issue so try to wipe the cache and data of the apps involved such as the messaging app and Contacts app.

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. 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.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

NOTE: Wiping an app’s data is the virtual equivalent of uninstalling the app, effectively deleting your messages and contacts. Make sure that you back important conversations before doing it. If you have a computer, you can easily save both messages and contacts using Samsung Smart Switch app.

If the problem returns after deleting the apps’ cache and data, consider doing a factory reset.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.
