The first time you use an app, and sometimes when you install or update it, you are asked to grant the app permission to access certain data and phone features.

You can adjust these permissions any time.

To adjust permissions by app:

1. Go to Settings > Apps.
2. Touch the app name.
3. Touch Permissions.

4. Turn each permission on or off as needed.

   TipTo see how the app uses each permission, touch > All permissions.

You can also review each feature and adjust which apps have permission.

To adjust permissions by feature:

1. Go to Settings > Apps.
2. Touch > App permissions.
3. Touch a feature to see which apps have permission to use it.
4. Turn that permission on or off for each app as needed.

Issues such as apps crashing, unexpected reboots, or fast battery drain could be caused by an app you intalled. Use safe mode to start your phone with only the original software and apps. If the issues go away in safe mode, the problem is probably from an app you downloaded.

To restart in safe mode:

1. Press & hold the Power button.
2. Touch & hold Power off until you are prompted to start in safe mode.
3. Touch OK.
4. Use your phone and see if the problem has gone away. Remember, you won’t be able to use any downloaded apps.

If the problem goes away:

1. To exit safe mode, restart your phone.
2. One by one, uninstall recently downloaded apps. After each removal, restart your phone. See whether removing that app solved the problem.
3. Once you delete the problematic app, you can restore the other apps you removed during testing.

If the problem doesn't go away: Try these troubleshooting steps for phone performance issues.

Press & hold the Power button, then touch Restart .

Or, hold the Power button for about 30 seconds, or until your phone restarts.

Clearing the cache and data can free up phone memory, improve performance, and fix some problems with apps and web pages.

1. Go to Settings > Apps.
2. Touch the app's name.

3. Do one of the following:

   • To free up space by removing temporary files, touch Storage > Clear cache. Over time, the cache builds up again, so repeat if a problem occurs.
   • If problems still occur, then delete all data saved in the app by touching Storage > Clear data. Be careful - there’s no way to undo this.

1. Go to Settings > Apps.
2. Touch the app's name.
3. Touch Force stop.

You can delete (uninstall) apps that you downloaded. For many preloaded apps, you can disable but not delete them.

1. Touch & hold the app's icon.

2. Do one of the following:

   • Drag the icon up and drop it on . This removes the app and frees storage space.
   • If you don't see a delete option, go to Settings > Apps, touch the app's name, then touch Disable.

If you are the owner of the phone and shared it with users or guests, you can uninstall apps they installed. Although their apps don’t appear in your app tray or on your home screen, they do reduce available storage space.

1. Go to Settings > Apps.

   Apps installed by others show the message Not installed for this user.

2. Touch the app name.
3. Touch > Uninstall for all users.
