Flip Case Control Trial is a utility app developed by MarksThinkTank for Android devices. It allows users to automatically turn off and on their device's screen by simply closing and opening the flip cover case.

With Flip Case Control Trial, users can conveniently close the flip cover case to turn off the screen and conserve battery life. When the case is opened, the screen automatically turns on, providing quick access to the device.

Please note that this version is a 24-hour trial, and if users find the app useful, they are encouraged to purchase the full version. It should be noted that Flip Case Control Trial is currently only compatible with Samsung ROMs and has been tested on devices such as the Galaxy S7 and Nexus 5X.

For users with black or dark flip cover cases, there may be issues with the sensor reading correctly when the case is closed. To address this, the developer suggests placing a piece of light-colored tape on the inside of the case where it lines up with the sensor.

Additionally, users who have a Note II and experience high battery usage are advised to turn off the "Reduce Sensitivity" feature, as the developer is currently working on a fix for this issue.

Overall, Flip Case Control Trial provides a convenient way to control the screen of your Android device with a flip cover case, offering potential battery savings and quick access to the device.
