How to use:
1) Click the 2nd line permission button to enable accessibility permission. If you enable the screen overlay permission, the power button appears on the screen.
2) Click Advanced Features in the 5th line. When you click the “press and hold” button in the second line, you can turn off the power by pressing and holding the back button.
3) The only way to turn on the power is to click the Shake function button and then click the “Shake screen to turn on” button. However, since it consumes a lot of battery, if your smartphone has a function that turns on the screen by double-clicking or by using a fingerprint, please use it. Thank you.
