Hope this is the right forum, didn't think support/troubleshooting was right since this is a hardware issue. My droid x is about a year and a half old and the back button has finally given out. It's not just unresponsive-- I literally can't click it, it's permanently depressed. It seems like maybe the sensor or something has slipped from under the hard button. Also, while the other three hard buttons have a white light shining through them, the back button is now green. I wouldn't think motorola would have powered different color lights in there, so I suspect maybe it's a symptom of whatever the problem is-- maybe something has broken allowing another light to shine through. I'm not sure though. Does anyone have any solutions? Can I re-map the hard keys? (I never use the search button anyway, and I'm rooted). This phone is NOT under warranty, so if it's something that can be fixed by cracking the phone open (and if I can find a guide that's easy to follow and gives me relative assurance I won't brick my phone) I'd definitely be willing to do that. The problem hasn't rendered my phone unusable, but it does make it practically useless except to make calls on. Thanks for the help.
