Samsung Galaxy S7 Edge randomly freezes while using applications after Android 7.1 Nougat update [Troubleshooting Guide]

  • Read and understand why a high-end device like your #Samsung Galaxy S7 Edge (#S7Edge), which runs the latest Android 7.1 #Nougat firmware, randomly freezes or experiences performance related issues shortly after the firmware update. Also learn how to troubleshoot your phone if this problem occurs.

Lags and freezes often go together as one may lead to another depending on how serious the problem is with your phone. Among the things I’ve seen in action are the phone first lags for a few moments then it starts to freeze for a few seconds and the issue escalates or the frequency becomes high that it’s impossible to use the phone normally due to interruptions.

There are also cases wherein apps are the ones causing the problem. This case is characterized by third-party or pre-installed apps that, when used, cause the phone to lag until the app in question is closed. Other apps may also cause freezes that may last a few seconds for each session and may occur every few minutes. These things will surely hinder you from using your phone normally and are extremely annoying you want to throw your device out of the window. Here is one of the problems sent by our readers that best describes this issue…

Troubleshooting Galaxy S7 Edge that randomly freezes after an update

Problem: Hi guys. I need your help as my Galaxy S7 Edge started to freeze every a couple of minutes or so making it unusable. It actually started as lags that last about a minute before it can recover then recently it started to freeze for some reason. It has been updated to Android Nougat I think and then this problem started. Do you guys know how to fix this? Thanks.

Random freezes are obviously firmware-related issues and considering the fact most of these problems occur after a firmware update, we can almost be certain that troubleshooting the firmware itself will yield favorable results. However, we need to rule out the possibility that it’s just an app problem or an issue with the caches and some system files. Go through the steps below and see if the problem gets fixed by one of the steps.

Step 1: Delete the system cache immediately so they’ll be replaced

The system cache can easily get corrupted every time the firmware gets updated. This must be the first assumption we have to make since the caches are expendables; you can delete them without experiencing any adverse effects on the performance but they can cause a lot of issues if the new system uses corrupt ones.

So, in this step, I will walk you through on how to successfully delete the system caches so that they can be replaced with new ones that work perfectly with the new firmware. You cannot access individual cache and you won’t know which cache is used by specific app or service. Therefore, the best thing you can do is to simply wipe off the entire content of the cache partition.

Once deleted, the new system will create new ones to replace them and this time, the cache will be completely compatible with the new system. This is how you do it:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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 wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Once the device has successfully rebooted after clearing the caches, observe your phone closely to know if the device still freezes and if so, then move on to the next step.

Step 2: Find out if the problem occurs when in Safe Mode

You need to try to isolate the problem to know if it’s caused by one of your third-party apps or if it’s an issue with the pre-installed apps or the firmware itself. Reboot your device in safe mode to temporarily disable all downloaded apps, after this and the problem is still happening, then it’s most likely we’re dealing with an issue with one or some of the pre-installed apps or it could be a problem with the system itself.

So, if the problem is fixed in this mode, the issue is with your downloaded apps. Find the culprit and clear its cache and data first, if that won’t work, then you may uninstall it. I understand you may have installed hundreds of apps on your phone so finding that one culprit may not be as easy as it may seem. If it takes more time finding the culprit than updating your files and data, then I suggest you do the latter and just factory reset your phone. This should fix the problem immediately.

How to boot Galaxy S7 Edge in Safe mode

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

How to clear app cache and data on S7 Edge

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch suspected app.
  6. Tap Storage.
  7. Tap Clear cache and then Clear data, Delete.

To uninstall, just follow the same method and tap uninstall.

How to factory reset Galaxy S7 Edge

  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.

Step 3: Perform the Master Reset procedure to know if the problem is with the configuration

Misconfigurations often result to performance issues like lags, freezing and random reboots and more often than not, bringing the phone back to its default settings will fix these issues. However, there are also times when corrupt system files and data will lead to this problem. The good news is we can hit two birds with one stone in this step. Doing the Master reset will bring back the phone to its factory defaults as well as delete corrupt system files and data. However, all your personal files and data will also be deleted, therefore, you need to back them up before doing these steps:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  3. When the Samsung Galaxy S7 Edge 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. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  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.

I am certain this kind of problem, which started after the Android 7 Nougat update, will be fixed by any of these steps so take time troubleshooting your device.
