If an Android device is sluggish, it may be due to digital clutter rather than a failing device. Users can improve performance by deleting unused apps, eliminating old files, tweaking home screen settings, optimizing device settings, and customizing privacy options. Uninstalling apps can free up storage and protect personal information. Users can manage files using the Files app or similar tools to delete or transfer unwanted items. Adjusting home screen settings can refresh the device's interface, while revisiting device settings can enhance user experience. Reviewing privacy settings allows users to control app permissions and safeguard personal data.
