My power button has had a mind of its own the past couple of days and its gotten a lot worse. Last feb. I got a replacement refurb from Asurion. Last week my power button has been clicking on and off non stop the screen has been going off, its trying to shut down and turning the phone on is a PAIN. I took a quick peek inside the phone (one screw is stuck so I couldnt get it completly open) and the button looked fine, it clicks fine. But there is no response when pressed. I need to start my phone into download mode so I can RELOCK my phone for Asurion purposes. I want to get a replacement while it is still on warranty. But when I try to get into download mode it just keeps turning off. And now that I had removed my battery. The phone gets to the SAMSUNG screen and then turns off. Any thoughts / ideas?! Please I just want to get it on atleast!
