Run your Galaxy A7 in Safe mode

There are times when third-party apps may cause this problem in fact, based on my personal experience, I have installed apps before that immediately resulted to sluggishness although I admit I was using an entry-level device when it happened. The Galaxy A7 has really impressive specs but then there would always come a time that its performance will slow down as it continues to accumulate data from apps.

We need to verify if your apps play a significant role that may have led to this problem that’s why it’s imperative that you run your phone in Safe mode. It temporarily disables all third-party apps and this is how you do it:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Should the phone run normally in this mode, then it’s confirmed there are third-party apps that cause the problem, move to the next procedure if this is the case.

Uninstall apps that cause the problem

Third-party apps can be uninstalled anytime without having any negative effects on your phone’s performance. In fact, it would give your phone a boost if you uninstall apps that cause issues. So, assuming that your Galaxy A7 works well in safe mode, the next thing you need to do is find those apps and uninstall them one by one:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager.
  5. Tap the desired application
  6. Tap Uninstall.
  7. Tap Uninstall again to confirm.

You may need to run your phone in normal mode every time you uninstall an app or you may need to reboot your phone to confirm if the procedure worked. After uninstalling some apps and the phone is still sluggish and slow, try to open apps you previously have issues with.

Clear cache and data of sluggish apps

If you still have some apps that still take time in launching, try to reset those apps by clearing their cache and data. Sadly though, you can’t reset them all once so you need to go through them one by one and here’s how you do it:

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

Depending on how many apps have issues, this procedure may take time to finish and after doing this and the problem continues, proceed to the next procedure.

Wipe cache partition

After doing procedures that would rule out the possibility that the sluggishness may be due to some applications, it’s time to go after the firmware itself. Another possibility is that some system caches may have been corrupted and we need to rule this out by wiping the cache partition off. Don’t worry, none of your files and data will be deleted if you did this:

  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.

After this procedure, continue to observe your phone to know if its performance improved. If it’s still slow and sluggish, then you need to do the ultimate method to make your phone run fast again–reset.

Backup your files and reset your phone

After you’ve done everything and your phone’s performance hasn’t improved a bit, it’s time to backup your files and data and then reset it. Sluggishness is often due to some issues with either the apps or the firmware and you can always fix it with this procedure, however, you need to backup your files and data as they will be deleted during the process. After which, make sure that you disable the Factory Reset Protection by removing your Google ID from your phone or you may just have to take note of your Google account and its password as you will be using it to setup your account after the reset.

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. 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).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.
  11. Press the Power key to restart the device.
