Fix 02: Clear Cache Partition

If the forced restart didn’t resolve the issue, you have to boot your device into recovery mode and clear the cache partition. This is a little advanced step, but don’t worry, We will guide you through it.

First, let your device’s battery drain completely to switch it off automatically. Once the device is off, plug it in and let it charge for about two hours. This ensures that your device has enough power to go through the next steps.

  1. Press and hold the Volume Up button and the Power button.
  2. When the Samsung logo appears, release both buttons.
