1. Delete unused apps to free up storage and remove unnecessary permissions.
2. Eliminate old files using the device's file management app to manage storage effectively.
3. Tweak home screen settings for a refreshed appearance without additional downloads.
4. Optimize device settings, such as enabling dark mode and managing app icons on the home screen.
5. Review and customize privacy settings to control app permissions and enhance security.
