Power button won't work

[Mark222]

Okay, I have a Sony Xperia C4 and yesterday the power switch won't function in all of a sudden; to the point that I need to wait for my phone to turn-off (not shut down) on its own.

I'm sorry to hear that, contact your Local support to get it inspected.

It happened to me too and in my case it was not a hardware issue but a software issue. I fixed it rebooting the phone.

With no power button you can force a reboot doing:

* Turn ultra-stamina on and off

* Wait for battery to runout

* Turn off the phone with the small button next to sdcard, but only do this if you are sure it is not just software
