How to turn off screen of android phone programmatically? I tried using following code with no luck 

PowerManager mPowerManager = (PowerManager) getSystemService(POWER_SERVICE);
mWakeLock = mPowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MYTAG");

mWakeLock.acquire();

    I'm not sure why you expected that aquiring a partial wakelock would turn the screen off(?) The documentation for `PARTIAL_WAKE_LOCK` even says _"Ensures that the CPU is running; the screen and keyboard backlight will be allowed to go off"_. "Will be allowed to" does not mean the same thing as "Will". – Michael Mar 31 '14 at 06:38

  • @rahulroy9202 setting brightness to 0 will dim the screen to its lowest values, it won't turning it off – Muhammed Refaat Aug 03 '16 at 09:27
