How to troubleshoot Galaxy S7 Edge that slowed down after the Nougat update

Problem: Nougat is supposed to make my phone faster, right? Such is the purpose of updating the firmware aside from security patches. However, my Galaxy S7 Edge seems to have slowed down noticeably after I downloaded the Nougat update. It’s not the first time that I updated this phone so I know that this time the update seems to have failed to improve my phone’s performance, which is really bad since I’ve been expecting it to even make it better. Powerful as it may seem, my phone not takes forever to open my email or text messages. What shall I do?

Troubleshooting: There are a lot of factors we need to consider when troubleshooting this kind of problem. However, we have to consider first that this problem occurred shortly after the Nougat update, which means that it could totally be just a firmware issue since Nougat is a major update and many of the cache and data may not be compatible with the new system anymore. There are a couple of procedures I want you to do, so continue reading below:

Step 1: Reboots your phone in Safe Mode to see if it becomes faster

Obviously, this is not the fix but it will give us an idea to know whether the problem is with your third-party apps or not. If the former have something to do with the slowing down of your phone, then you just have to find the culprits and uninstall them and probably download new versions of those apps again. However, if the problem still persists even in safe mode, then it must be the firmware that we have to look into. Here’s how you boot your 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.

I am hoping that this problem is not as serious as it seems and can only be fixed by uninstalling some apps. However, if the issue is with the firmware, then the next step should take care of it.

Step 2: Backup your data and do the Master Reset

I understand the phone is so slow and it might take forever to backup everything in it but please try, at least, salvage your important files first because one the reset is done, they will be deleted and can no longer be retrieved. After the backup, do this procedure:

  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 hope this helps.
