If I hold my power button, I presented with the option to "Power off" my device. I touch it, and my phone (a LG Nexus 5 running on Android 4.4 KitKat) indeed turns off. However, it suddenly turns back on. If I power off multiple times, it eventually stays off. Is this normal? Does the phone restart if it is aware of pending updates or something?

  • No, it's not normal. If you are in warranty, go to the service center. OTA updates aren't triggered automatically. You need to tap it from notification.

Because long pressing the power button on all most any android device(if not all) will reboot the device. It is meant to be the restart button in case on a device something goes wrong, you have the option to hard reset the device.

To correctly shut down a device you have to tap the power button and select the option to power of, or if you are in CWM select "Power off device", or I think you can shut it down using adb to.

  • This is likely the issue. I haven't observed the reboot issue the past couple days. If I do, I'll look into replacing it.

"Power Off"(menu selection) actually reboots my Kit Kat if it's plugged into the computer with USB debugging on. If i disconnect, the power off powers off.
