Power button is not responsive when being hold on LG Optimus F3 I have an LG Optimus F3. Last night, I wanted to screenshot something, but holding the power button didn't do anything. I can press it and the screen would turn on/off, but there's no response when holding it.

I tried holding it for a good 1 minute, but it still isn't working.

How to fix this?
This is a routine issue for me.

Removing the battery to force a reboot temporarily fixes the problem. I haven't found a permanent solution though.
