Battery Saver Go for Android
This app allows you to tap a notification bar to lock and black out the screen but keep your game running.
This means you can save battery life while walking around by putting the screen in a lower power state, and you to safely put your phone in your pocket without worrying about pocket dialing or accidentally pressing other buttons when your phone is on and in your pocket.
How to use
1. Launch Battery Saver GO and an icon will be added to your notification tray.
2. Switch back to your game.
3. Tap the notification bar and your phone will dim to its darkest setting and the touch screen will lock.
4. When you want to go back to your game, double click the screen to unlock the screen.
Notes
- Don't press your phone's power button after locking your game as that would cause your screen to fully turn off and for your game to stop.
