We need more information, how did you get to this point? You must have done something to trigger it?

It just says you're in fast boot mode.

More details please?
So on just hitting the power key, your phone goes in fast boot? It's possible that the key section is faulty hence causing this. Go and swap the phone.

Note 2 switches off by itself

Hi guys. Thanks for helping me get my note 2 up again. Now a problem that had been with my phone for a long time; the phone goes off by itself, even when it's on top of a desk untouched. Sometimes it goes off when it's charging and someone's when it's in my pocket.
I have to press the start button for like ten seconds to boot it; otherwise I remove the battery and replace it then press the start button like normal.
I tried flashing new factory roms to no avail; problem persists.
Other thanthis issuethe phoneworks verywell. What can I do to get this phone to work properly?
Thanks guys.

Maybe but I have no idea. How could one solve this problem if it happens to be the one?

From your description it can't be a simple loosened battery, I think its hardware related since flashing new roms dousnt work. You still have warranty?

It's probably the power button. S2s have a problem with the button getting stuck internally. The button feels and functions like its fine but inside its not. I've had customers tell me they YouTubed on how to fix. Or if the device is under warranty still exchange it. Hope this helps.

Thanks everyone for all your help @TheSickness was correct I'm debating if I should upgrade to an s5.

The S5 finger print is a major target for hackers to steal your identity. Just saying, if you upgrade, make sure you don't goof up. I'm almost afraid to upgrade to the S5, been thinking of getting a note again. But really IDK. Maybe I'll keep my S4 and get a tablet or a kindle. Something to do my desktop website development work on.

Take out the battery and put it back in. If it tries to power on by itself you have a faulty power button.

Cool! If it begins to happen again, Odin flash the firmware and factory reset. If its software related this should take care of it.
Thanks, I will let u know what happens
