How to lock and unlock screen programmatically in appium

In android phone how to lock and unlock the screen using appium

AndroidDriver provides the following methods to lock and unlock the device - isLocked(), lockDevice() and unlockDevice(). These methods are available in AndroidDriver, so if your driver is of type AppiumDriver then you need to cast it to AndroidDriver -


Also, please note that these methods won’t work if you save set up a pin or passcode on the device.

The lock device works for me , but the other direction for unlocking fails every second execution …
