The bottom row buttons on my Thunderbolt quit working one afternoon. They are part of the touch screen technically. I shut the phone off, and then started it back up, and it was fine. I just thought it was a software glitch. Then, 2 weeks later, it happened again, but this time the restart didn't fix it. Then it got to where the buttons only worked about 10 minutes per hour. I had to send it in for replacement.
Not trying to rain on your parade, but it still could be hardware.
Verizon won't trade out in the store any more. They will only overnight you a replacement.
I called their device support, and told them that the touch screen wasn't working all the time. Told them I had rebooted, pulled battery etc, and there was no questions asked.
They overnighted a replacement, I switched over to the new one, and unrooted the old one to return it.
I've done warranty replacements before and they send you a replacement with a return shipping label. You have to send your phone back within a certain period of time, or they'll charge you for the replacement.
ok, I have a nused device coming today. My current one was being totally unpleasant to use. When potion of the screen does not work, that IS hardware? When things seem to press themselves, that IS hardware?
Then this AM, I get a box asking to setup a task. But NEVER saw this style of box before. And already had 'porn' typed in. There was an option to 'speak' but again, it was an all white I have not yet seen.
Tried to get a screengrab and got a FC instead. Tried again and got a black image. Hindsight should have taken a picture w/ my tablet.
Did a nandroid and My backup and then complete and full wipe. Installed G3D 1.2 and now it is all frisky n stuff. No issues of any kind.....
