Phone keeps switching on and off, stays off. What should I do?

My phone just switched off in the middle of a call and won't switch on now. When I try and switch it on, I just see the Google logo and then it turns off again. How do I switch it on again?

Same issue here! To me it seems that when the battery goes below 80% it turns off. If I use an external battery to keep it up to 100% then it seems stable. I don't know if replacing the battery will help.

I'm having the same issue...from what I have read I gather that it is a faulty power button all together. Also my further reading leads me to believe that you either need to replace to motherboard or do some serious soldering in order to fix it.

I don't know if it's the same problem i'm having, but it's similar. In my case, it appears to be more of a display issue. The screen turns off at random, but at times it merely becomes touch-insensitive. And sometimes there's odd "static" on the display.

I assume it's a bad display connector; I'm looking into replacing the screen or having it replaced.

Hopefully I will *not* have to replace the motherboard.

Joshua, where have you been reading about this problem?

Replaced the battery and that fixed it. But be careful. The battery will catch fire if shorted.

Take the fuckong battery cover off and literally flick the back of it right where the power button is a few times and press it at the same time on and off and you will see when it powers up then stop flicking it. Guaranteed to work 100%

I too had the same problem which I fixed myself.

It the problem with Power Button. Due to multiple ON/OFF or some moisture it is internally shorted, which means Power Button is always in ON state.

You need to de-solder it. and replace with working power button.
