Troubleshooting your Galaxy S7 that started running slow after Nougat update

Problem: Hello guys. I am hoping you can help me with my problem because it seems that my Galaxy S7 is now having a difficult time doing things I want it to do. In other words, it’s very slow now and it takes forever to open apps. For instance, when I try to call someone, I just open the phone app and then dial the number. That’s how it worked before but now, I tap on the icon, wait for a couple of minutes, dial a number, wait for the call to connect. I’m not really sure if it was the update that caused this but it seems the problem started after the Nougat update. Can you guys tell me what to do about it please?

Troubleshooting: The good news is your phone still powers up and runs so for now, you can rest assured that the hardware components are fine and that the problem might have something to do with the firmware or some of the apps. So, we will try to rule out one possibility after another until we can tell what the problem really is and why your phone is running very slow after an update. To begin our troubleshooting, here’s what you need to do:

Step 1: Reboot your phone in Safe mode to know if it still runs slow

The first thing we need to find out is whether the problem is caused by a third-party app or not that’s why you need to boot your phone up in Safe mode as all third-party elements are temporarily disabled in this environment. Assuming the device runs normally or fast in this mode, then it’s clear that one or some of the apps you installed in causing the problem, although, it doesn’t necessarily mean the culprit is the one you installed. There are times when some apps secretly install other apps that run in the background but take up more resources. But whatever the case may be, booting in safe mode is necessary. So, here’s how you do it:

  1. Turn your Galaxy S7 off.
  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.

Assuming your phone runs normally while in safe mode, then it’s clear that the problem is caused by one or some of the apps you installed. To address this, you have to find the apps that are causing the problem, try to update, reset and even uninstall them.

How to update apps on your Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

How to clear app cache and data on Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display preinstalled apps.
  5. Tap Storage.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

How to uninstall apps from your Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display preinstalled apps.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

Step 2: Reboot your phone in Recovery Mode and wipe cache partition

Just in case the phone is still running slow while in safe mode, then you need to do this since you said the problem started after an update. Regardless whether it was a minor or a major update, the fact that this issue started after that is evident the problem might have been caused by some corrupt caches. So try to follow the steps below to reboot your phone in recovery mode and wipe the cache partition to delete all system caches and that they will be replaced:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition’.
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Don’t worry, this procedure is actually safe for your phone as well as for you data and its very effective in dealing with issues that may have occurred after an update. If this doesn’t work however, then you have to move on to the next step.

Step 3: Backup your files and data and reset your phone

It’s now time to reset your device since you haven’t fixed the problem with the first two steps. But before you actually reset your phone, make sure you backup your files and data since they will be deleted during the process. Also, if possible, disable the Factory Reset Protection or anti-theft feature so you won’t be locked out of your device after the reset.

  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.
  9. Tap REMOVE ACCOUNT.
