Most common problems of Samsung Galaxy S7 Edge owners may encounter are random freezes and lags, system slow down, and unexpected reboots or shutdowns. They’ve been happening with previous Galaxy models and maybe my post will help you in fixing these problems :

Step 1: Find out if the problem is with your apps

You may have already downloaded a lot of apps so it might be difficult to pinpoint the culprit but that doesn’t mean you can’t do anything about it. There are two general categories of apps; pre-installed and downloaded or third-party.

If the problem occurred after installing some apps, then you can almost be certain one of those caused the problem. However, if it’s difficult to pinpoint which app it is, you need to boot your phone 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.

In this state, all third-party apps are temporarily disabled so if one of them caused the issue, then the problem shouldn’t occur.

Even if you already know that one of the downloaded apps is the cause, you may spend a few hours trying to find which one is the culprit. So, to make things a little faster, begin your troubleshooting with the recently installed apps.

Boot your device in normal mode and try to disable or uninstall suspected apps. However, if you’re not into finding the specific app that’s causing all this trouble, then I suggest you reset your phone to uninstall all of them and try to download them one-by-one.

In case the problem still occurs in safe mode, the possibilities are the problem is caused by a pre-installed app or it’s a firmware issue. Proceed to the next step.

Step 2: Find out if it’s about a corrupt system cache

The system cache can easily be corrupted especially after an update as the old files will automatically become obsolete. But unlike the system data, the cache can be deleted without the fear of losing settings, files, and other data, etc. In fact, it’s always recommended you delete the system caches every time you experience issues with your phone’s performance like random reboots, slowing down, unexpected shutdowns, etc.

Once you’ve deleted the cache or wiped off everything inside the cache directory, the new system will create new files and this time, you can reset assured that everything is compatible.

Moreover, it is also important you do this step as some pre-installed apps may have also corrupted their caches causing them to freeze, hang or crash that will eventually affect the general performance of your phone. So, to delete the system cache, follow 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.

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 doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

9.	The phone will now reboot longer than usual.

Step 3: Bring the phone back to its factory settings

After booting the phone in safe mode and deleting the system and the problem still persists, it’s time to do a more complicated and a lot more hassling troubleshooting procedure, the master reset. For this, you need to backup your files, music, videos, photos, apps, data, etc. You can move them over to your SD card or copy them to your computer because they’ll be erased when you follow the steps below.

But just before you do the reset, remove your Google account from your phone and disable any screen locks you may have engaged to make sure the Factory Reset Protection or anti-theft feature won’t be tripped. Once ready, follow these:

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.

Step 4: Request for technical support

Or, you can just bring the phone in to your provider and have it’s technician check it up for you. If you’re within the replacement period and the problem can’t be fixed, you may receive a brand new unit. But the point is, you’ve already done everything you could to no avail, it’s time you had an authorized tech help you with it.
