Learn how to use the task manager and free up memory on the Samsung Galaxy S III.
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 Home screen, press and hold the Home key.
- Tap the Task Manager icon.
- Choose from the following options:
- Close active applications: To close active applications, tap the Active applications tab and then tap End next to the desired application. Tap End all to close all active applications.
- Uninstall applications: To uninstall applications, tap the Downloaded tab and then tap Uninstall next to the desired application.
- Clear RAM: To clear RAM, first save any necessary data. Tap the RAM tab and then tap Clear memory.
- View available memory: To view your memory card and internal memory's available storage, tap the Storage tab.
- Help: Touch the tabs section and drag your finger left and then tap the Help tab to read about the RAM manager and how to extend battery life.
