Rotation Lock Adaptive (Free) [Android]

Adaptive rotation - if you find automatic screen rotation annoying then this app is for you. It will detect the device's orientation and show a transparent button to let you decide whether the screen should be rotated to landscape or portrait

Lock the screen in landscape or portrait - it will lock the screen the way you want even when some apps don't offer certain orientation

Increase productivity - unnecessary rotation will distract you and interrupt your workflow!

Power saving - every screen rotation will involve a lot of computation. By reducing unnecessary rotation the battery will last a bit longer

There are 8 modes which can be chosen in notification bar:
1. Adaptive mode - detect the device's orientation and prompt you whether to rotate the orientation
2. Landscape - force the orientation in landscape
3. Portrait - force the orientation in portrait
4. Reverse Portrait - force the orientation in reverse portrait
5. Reverse Landscape - force the orientation in reverse Landscape
6. Force auto - automatically rotate the screen in all orientation
7. Stock auto - exactly the same as original auto mode
8. Stock portrait - exactly the same as original portrait mode
