Method 2: Mass cleaning of the cache

  1. Open Settings โ†’ Memory โ†’ Cleaning.
  2. Click Clean up garbage (the system will scan the device and show how much space can be freed up).
  3. Confirm the action.

After cleaning the cache, restart the smartphone - this will help the system correctly recalculate the free space.
