Clear App Cache/Data:

NOTE: If one of your apps doesn’t work as intended, freezes, crashes or takes up too much storage inexplicably, alternatively you can try fixing these issues by clearing the app cache/data.

WARNING! When you clear an app’s data, all your personal data stored within the app will be deleted, including user profiles, custom settings, save files etc. To avoid losing personal app data, clear ONLY the app cache.

1. Launch “Settings”
2. Go to “General” and tap “Apps”
3. Select the desired app
4. Tap “Storage” > “Clear cache”
5. If clearing the app cache didn’t help, tap “Clear data” > “OK” (check the WARNING above)

Wipe the Phone’s Cache Partition:

NOTE: If your phone freezes, crashes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering a factory reset, alternatively you can try fixing these issues by clearing the phone’s cache partition. This can have results similar to a factory reset without losing personal data from the phone.

1. Launch “Settings”
2. Access “Phone Management”
3. Tap “Storage”
4. Tap “internal storage”
5. Once the phone finishes calculating the data, tap “Cached data” > “Clear”

NOTE: If clearing the cache partition didn’t help, you can check this thread for instructions on how to factory reset the device.

Reboot to Safe Mode and Uninstall an App:

1. Press and hold “Power” on the home screen
2. From the Power Management pop-up, tap and hold “Power off”
3. At the “Reboot to Safe Mode” prompt, tap “OK”. After the phone reboots, a “Safe Mode” watermark should be visible in the lower area of the home screen
4. To remove an app, first open “Settings”
5. Go to “Apps” > “All apps”
6. Select the desired app and tap “Uninstall”
7. Tap “OK” to confirm
8. Once done, you can exit Safe Mode by rebooting the phone normally
