I have a HTC Inspire 4G and the problem that I'm having usually happens only after I make a phone but not when I recieve a phone call. I will click end call and it will take me to the lock screen and when I try to slide the bubble up to unlock it and go to my home screen it will not accept my scrolling the bubble. I can do this several times until the back light goes out. Once the back light goes out I then can not turn the phone back on for several mins, and to finally get it to come back on I have to click and hold the power button (not sure what that does). But after dealing with this for a while it seems to be happening more and more often now. I have tried to restart it with it changing nothing and seems to have made it worse. Is there anything else I should try before contacting ATT? 　 Thanks.
