Learn how to use the task manager and free up memory on the Sony Xperia Z1s.
Restart device regularly
You should restart your phone at least once per day.
Reduce memory use
Animated widgets and widgets that update information use the most memory. If your phone is running slow, you can reduce the amount of memory it is using:
- Replace a live wallpaper
- Remove widgets
Manage apps to keep your device running smoothly
- Use Manage apps to update apps, clear app cache and data, recent apps, and uninstall an app.
- Never install a third-party Task Manager or Battery Manager. These apps interfere with how device software works.
- Research and monitor new apps that you install.
- Read app reviews before installing. Not all apps run smoothly on phones. Read customer reviews before downloading an app to see if it has a history of not working properly.
- If your device starts having problems after installing an app, consider uninstalling the app. (See Manage apps.)
A task manager can view running apps and close them.
- From any screen, tap the Task manager key.
- To open a recently used application, tap the thumbnail.
- To close a recently used application, touch the thumbnail and slide it to the right.
- From any Home screen, tap the Applications icon.
- Scroll to and tap Settings.
- Scroll to DEVICE, and then tap Apps.
- Touch the screen and slide left to view the Running screen.
- View the "free" value in the lower-right corner.
