Wiping the Cache Partition:

NOTE: If your smartphone freezes and / or is not working correctly, then you might solve these issues by clearing the cache partition. Unlike master resetting a smartphone, when you wipe the cache, you won't lose any personal data stored on the internal memory of the device. To wipe the cache:

  1. With the smartphone turned off, press and hold the "Volume up", "Home" and "Power" buttons at the same time
  2. After the phone vibrates, release the "Power" key but keep pressing and holding the other two buttons
  3. When the "Android System Recovery" screen appears, release the "Volume Up" and "Home" buttons
  4. Press the "Volume Down" button until you highlight "wipe cache partition"
  5. Press "Power" to select the highlighted option. Your handset will now reboot in normal mode, with the cache partition cleared

NOTE: if clearing the cache did not help, you might have to try and factory reset your device. To learn how to factory reset the Ace 3, follow this link for a full guide.

  3. After the "Samsung" splash screen pops-up, release the "Power" key, and immediately press and hold the "Volume down" button
  4. Keep holding the volume key until the smartphone finishes rebooting
  5. A "Safe mode" note should appear in the bottom-left corner of the screen

Uninstalling a Third Party App and Turn of Safe Mode:

  1. While on the home screen, press the "Menu" button
  2. Tap "Settings" and tap the "More" tab
  3. Tap "Application manager" and swipe to the "Downloaded" screen
  4. Select the desired application and tap "Uninstall"
  5. Tap "OK" to confirm
  6. To exit safe mode, press and hold the "Power" button and tap "Restart"
