Well I took it to a Sprint store and the tech said the button is physically fine, and worked when doing a hard reset but once the phone came back on it went back to not working again. So he thinks it's a software issue and ordered me a replacement. And my E4GT is completely stock, never rooted. Just decided to let u guys know just in case anyone else happens to have the same problem.

Last night while using my phone it suddenly rebooted itself, and when it came back on the power button no longer worked. I could use the volume buttons to wake the phone, but even that stopped working after a while. I went to sleep and let it charge overnight, and when I woke up, all was working normally. Its been normal all day until a few min ago, the phone rebooted and now once again the power button wont work. Anyone had this problem? Any suggestions, besides take it to Sprint, which I will do if it continues?
