How to turn off screen of android with terminal emulator? I am using Android 5.0.

  • In ADB, try 'adb shell input keyevent 26' (no ' marks)

    @DanB From an in-Android Terminal emulator, it's just input keyevent 26. It's worth noting that the phone didn't accept this event, unless sent as root.

  • @DeathMaskSalesman Ah OK. I was not sure at what point to shorten it to.

  • @DanB Your version is perfect for use from adb, and it may also avoid the user to be root.

  • @DeathMaskSalesman Yes, which is why I suggested it in the first place. I left it as a comment because its too blunt/short for an answer.

There are two ways of doing this, depending on if you have root or not on your device.

If you use root

If you have rooted, run:

input keyevent 26

In any good terminal emulator.

If you have not rooted

If you haven't rooted, either root, or:

  1. Install ADB (Instructions vary between windows, Mac and Linux)
  2. Enable "USB Debugging in settings > developer options (if you cannot find developer options, tap the build number in 'about phone' seven times.)
  3. Connect your device to the PC, and connect via ADB
  4. Run: adb shell input keyevent 26
  • Thaaaaaaaaaaaaaaaaaank's its work 5/5 :)
