Galaxy S7 Edge lags, freezes then shuts down on its own after the update
Problem: I own the Galaxy S7 Edge phone and a few days ago there was this notification that it needs to be updated or something so I downloaded the update and then everything went well or so I thought. The phone rebooted without me doing it and I’ve actually used by phone for a few days until one day it started to lag and then it started to freeze. It became more frequent like it freezes every few minutes now and then it started to just shut down on its own. I don’t know why this is happening but it’s very annoying. So can you guys help me fix this issue? Thanks.
Troubleshooting: In other words, your phone is currently bugged by the most common performance issues. Actually, when it occurs, it starts out as a lag then it progresses into freezes with its frequency growing by the minute. As you continue using your phone, you’ll notice that it became really slow and there are cases wherein the device randomly reboots or shuts down. While it’s clear enough that the problem started after the update, we can’t simply conclude that it’s an issue with the firmware since there are other factors that may have also contributed to this kind of issue. It is therefore, imperative that you perform basic troubleshooting to determine what the problem is all about, know what the cause is and learn how to fix it. With all that being said, here’s what I suggest you do…
- Boot your phone in Safe Mode. It’s necessary so that you’d know if your downloaded apps have something to do with the problem. If the lags, freezes and shutting downs disappear when in this mode, it’s clear enough that one or some of your apps is causing the problem. Find it and uninstall it so that your phone will normally again.
- Wipe the cache partition. By doing this, you’re actually forcing the phone to create new system cache to replace obsolete or corrupt ones created by the previous firmware. Doing this won’t delete any of your files or data and it’s very effective in addressing firmware issues that started to show after an update. You need to boot your phone in recovery mode to be able to do this.
- Master Reset your device. If the phone still occurs in safe mode and wiping the cache partition didn’t fix the problem, then you really have to reset your device to bring it back to its factory default settings. Your files and data will also be deleted so make sure you make a backup of the most important ones.
I hope this helps.
Samsung Galaxy S7 Edge App freezes and reboots randomly after updating its system
Problem: Hi! I purchased my S7 Edge last month but now it started to reboot without apparent reason. Yesterday I tried to turned it on and it’s working again but when I open an app my phone freezes and restarts and stuck in Samsung logo. If you can help me fix my issue that would be great. Thanks!
Solution: Hello! This problem will range from firmware to hardware related issue. If your phone was dropped or soaked in the water then that may be the reason that the device could not boot up completely. But if not, then it could be a firmware problem. So, to make sure what really the problem is, you can isolate the issue by following the steps provided below:

There is a possibility that the device has a minor firmware issue, so, performing the force reboot procedure might fix the problem. This method is equivalent to a battery-pull procedure to other devices that has a removable battery. To do this, just press and hold the Volume Down and Power keys together for 10 seconds. If the phone reboots, then it might be a minor firmware related issue. But if it refuses to turn on you can proceed to the next step.
Step 2: Restart your Phone in Safe mode
If you recently downloaded some apps before the issue started that could be one of the possibilities that your phone stuck in Samsung logo. By booting it on Safe mode all the downloaded applications in the system will be stopped from running and if the device will turn on without an issue it should be one of the apps is culprit.

Samsung Galaxy S7 Edge will suddenly shuts off and reboot after updating the system
Problem: I have a 10 months old Galaxy S7 Edge but started the other day it restarts itself randomly. When I’m surfing the web or opening an app my phone will suddenly shuts off and restarts itself. I don’t have a warranty on my phone. I’d really appreciate it if you help me. Thanks!
Solution: If we have to look at the symptoms it seems like your phone has a firmware related issue. But since, it’s too early to jump directly to the conclusion the first thing that you should do is to determine what really caused the problem. In fact, this issue is common to all Galaxy S models especially if there’s an update happened to the firmware. At this point, you can boot your phone in Safe mode to disable all third-party apps from running in the system. So, if the device won’t shuts off while in this mode then there’s a culprit in the system that triggered the issue. You can uninstall every app you installed recently until the issue will be fixed.
However, if the device still function abnormally then you can perform the next procedure by deleting the system caches of the phone. The caches are the directory where the files are stored and responsible for the device to run smoothly every time you have to open an app or turn on the device. So, deleting the caches is advisable to all users especially if you updated the system of your phone. However, if Safe mode and deleting the system caches won’t worked on your device,then performing master reset is your last chance to fix the issue. This procedure will bring back the device to its default settings and removing all those leftover caches that had been corrupted and outdated. But before going through make sure to backup everything because all your stored files will be deleted.
