  • •Access to device settings and permissions to manage storage.
  • •Backup important data (photos, documents) to prevent loss during cleanup.

Method 1: Clear Cache and Data

This method is effective when apps accumulate cache data over time, consuming significant storage space.
  • •Step 1: Open the 'Settings' app on your device. You can find this in your app drawer or by swiping down from the top of the screen and tapping the gear icon.
  • •Step 2: Scroll down and select 'Storage'. You will see a breakdown of your storage usage.
  • •Step 3: Tap on 'Cached data' or 'Other apps' to view apps using storage. Select an app to see its storage details.
  • •Step 4: Tap 'Clear Cache' to remove temporary files. For a more thorough cleanup, tap 'Clear Data' (note: this may reset app settings).
  • •Step 5: Verify the storage space has increased by returning to the 'Storage' menu.

For Android 11 and later

Android 11 introduced a more user-friendly storage management interface.
  • •Step 1: Go to 'Settings' > 'Storage'.
  • •Step 2: Tap 'Manage storage' to see suggestions for freeing up space.
  • •Step 3: Follow prompts to clear cached data or delete unused apps.

For Android 10 and earlier

Older versions may have slightly different paths.
  • •Step 1: Open 'Settings' > 'Apps & notifications'.
  • •Step 2: Tap 'See all apps', select an app, and proceed to 'Storage'.
  • •Step 3: Clear cache and data as needed.

Method 2: Uninstall Unused Apps

Removing apps that are no longer needed can significantly free up storage space.
  • •Step 1: Open the 'Settings' app and navigate to 'Apps & notifications'.
  • •Step 2: Tap 'See all apps' to view the complete list of installed applications.
  • •Step 3: Select an app you no longer use and tap 'Uninstall'. Confirm the action when prompted.
  • •Step 4: Repeat for any other unused apps to maximize storage recovery.
  • •Step 5: Check your storage again to confirm the increase.
