Problem 1: Galaxy S7 My Files app stopped working after Nougat update

The “My Files” Application will not open after upgrading my Samsung Galaxy S7 edge to Nougat via OTA update. I have, to a certain extent, knowledge of how to clear the data and cache to try and resolve the problem. The problem keeps persisting even after me clearing the cache, clearing the data, forcing the App to stop and then rebooting my device to reload the correct data. Nothing and no solution has prevailed. Kindly assist what next step should be take. Thank you        . — Ebrahim786

Solution: Hi Ebrahim786. If wiping the app’s cache and data didn’t fix the problem, you must the cache partition wipe and factory reset.

Below are the steps how to do each of them.

Wipe S7 cache partition

  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.

Factory reset a Galaxy S7

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Problem 2: Galaxy S7 edge keeps going back to sound mode, won’t stick to silent or vibrate mode

Hello. I HAVE a Samsung S7 edge. when at work I turn off the ringer and notification sounds by putting the phone on vibrate only. My issue is that when I unlock the phone at any point during the day the ringer and sounds automatically switch back on. HOW do I keep this from happening? Thanks in advance. —  Colin

Solution: Hi Colin. This may be cause by a software bug following an update so make sure to wipe the cache partition first. Refer to the steps above.

  1. If wiping the cache won’t work, try this workaround:
  2. From a Home screen, touch and swipe up or down to display all apps.
  3. From a Home screen, navigate to Settings>Accessibility settings icon.
  4. Tap Hearing.
  5. Tap Mute all sounds Colors to turn the slider on or off.

Note: These instructions apply to Standard mode only. If you are in Easy mode, here are the steps on how to switch to Standard mode first:

  1. From a Home screen, navigate: Apps icon>Settings icon>Easy mode icon.
  2. Tap Standard mode then tap APPLY (located in the upper-right).

If this workaround won’t help either, consider wiping the phone with factory reset.

Problem 3: Galaxy S7 active shuts down randomly

I have the little known Galaxy S7 active. having the ruggedized case and larger battery. on at least 6 occasions , the phone will shut down. soft reset does not work , (and other combinations with Home key etc). The only way to bring it back seems to be to connect it to USB. the screen will show empty battery icon with charging lightning bolt for a few seconds, then the battery icon will “fill on occasion over 50%.

the shutdowns have happened typically when there is a lot going on, panoramic camera shot or getting a vibration alert when running some other application. It has not been with one consistent element that I can identify. my theory is the battery voltage is temporarily dropping enough to shut it down as a low voltage protection. and until it has received confirmation of I higher voltage through the charger, the system will not reboot, thinking the battery was critically low. I hope this makes sense. — James

Solution: Hi James. We suggest that you start with factory reset to check if this is being caused by an unknown bug. Once you’ve factory reset the phone, observe it for  at least 48 hours. Be sure not to install any third party app or update during this time. While observing, make sure to put stress to the phone by using it extensively for games (if there are pre-installed ones) or let it receive notifications so it uses its vibrate motor. If the problem won’t occur at this time, that means the cause of the problem is software or app-related.

On the other hand, if the problem stays and the phone’s behavior won’t change even after a factory reset, you should consider sending the phone to Samsung so its hardware can be checked or repaired.

Problem 4: Galaxy S7 won’t turn off, stuck in PIN lock screen

I have the Samsung Galaxy S7 (not the Edge), and the phone was fine last night before bed, had about a 40% charge. When I woke this morning (luckily on time), I discovered the phone was dead. It would not power on. I charged for about 20 minutes, still not responding.

I found your site through a Google search. I done the reboot (Power + Vol Down), and it gets to the “Enter your Pin”, and it accepts my entry. But then when it shows the Unlocked Padlock symbol with the blue and green circle around it spinning…it stops. The circles keep spinning, but it is stuck at this point. I have rebooted the same way 3 times, and no difference. It is completely unresponsive on this screen as well. — Michael

Solution: Hi Michael. The first thing that you want to do now is to turn the phone off again. You can do that by either pressing and holding the power button for at least 12 seconds. If that won’t work, you’ll have to wait until the phone has exhausted the charge.

Once the phone is turned off, you then want to boot the device to Recovery mode so you can either wipe its cache partition or perform a factory reset. Here’s how it’s done:

  1. Charge the phone for at least 30 minutes.
  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. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 5: Galaxy S7 not making sound notifications for incoming SMS

I am having issues with my Samsung Galaxy S7 active. I am not receiving any text message notifications at all. No sounds and nothing on the display on the top of the screen or on the lock screen. Everything is turned on like it is supposed to be. It stopped working a couple of days ago and I don’t know why. I have checked all of the settings numerous times and tried restarting the phone. Please help! — Natasha

Solution: Hi Natasha. To ensure that you allow sound notifications for any incoming SMS, you’ll have to do the following:

  1. Open the Settings app.
  2. Tap Notifications.
  3. Find the default messaging app in the list and ensure that the slider is set to the RIGHT. This will allow notifications for said app.
  4. Once you’re positive that the default messaging app is allowed to receive notifications, tap the ADVANCED button at the top-right corner.
  5. Look for the messaging in the list and tap it (the word Allowed should show under the name of the app).
  6. Customize the options in the screen that shows. You can try to enable Set as priority to see if it will make a difference.

If you’ve already set the notifications as above beforehand, try wiping the cache and data of the messaging app you’re using. Here’s how:

  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 or 7.
  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.

Problem 6: Galaxy S7 won’t turn on

For the last couple of months my partners phone has been blacking out but we have been able to reboot it with the volume down and power button held down. today it has totally died and won’t respond to any of the fixes you’ve suggested. any ideas or do you think its totally dead? — Nicola

Solution: Hi Nicola. Your options are very limited when it comes to an issue like this. The only suggestion we can give you is to try to boot the phone to alternate modes to see if it turns on. Only then can do follow up troubleshooting. If the phone remains dead after trying the different hardware button combinations, send it in for repair or replacement.

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  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. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN 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 DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 7: Galaxy S7 won’t receive SMS notification when messaging app is not being used

I have the notifications for messages on. I have done the factory reset. if I’m on my phone already it will pop up but the notification icon for messages will disappear from the status bar… so if I’m not on my phone it still doesn’t not notify me unless I go in to the messaging app entirely. — Megan

Solution: Hi Megan. Please check our suggestions for Natasha above. If nothing works, do a factory reset. Refer to the steps above.

Problem 8: Galaxy S7 edge not receiving Nougat update

S7 edge sm-g935v not updating to Nougat 7.0. I don’t really understand why it’s not giving me the update. maybe I’m just being impatient but my wife and I just got these phones a few day ago and hers updated just fine but for some reason mine isn’t. We ordered them online and unlocked so that we can use them with Straight Talk. I have tried going to system update and it says it is up-to-date. — Corey

Solution: Hi Corey. If both devices are exactly the same (phone model and software version) when you received them, then it’s just a matter of time before yours will receive a notification for an update.

You can also use Samsung Smart Switch app to check for updates. Make sure that you install this program in your computer first before connecting your phone to your PC.

Problem 9: Galaxy S7 sound/audio issue

I tried safe boot. I tried to change my message tone. I get the default message tones to pick from or from my files. I have tried both ways and still no luck. I fixed the no sound problem that was caused by CM security which now they call CM monitoring. I even tried to change it with Zedge but no luck. I tried through the massager and also through system settings. No luck. Galaxy S7. still has the one I set it to a while ago and can not change. — Scott

Solution:  Hi Scott. We don’t think we understand your problem here. Kindly get back to us and tell us what exactly are you having trouble with. We will update this post accordingly.

Keep in mind that the best solution to any possible software problem is factory reset. If you haven’t tried that yet, make sure to do that before contacting us again.
