I've had issues with my screen for the last month and a half and was hoping 2.2 would fix it. The screen will stop responding to touches in certain areas and the bottom buttons will fail to work. The quick fix is to lock the device with the power button and unlock. It will work great for 10 minutes or so and then start acting goofy again. When it's really bad, there is dead part 3/4 up the screen. If I try a reboot, the "Power Off" button is in the dead zone and requires me to remove the phone from the case and remove the battery to even do a reboot. I have security on with a finger swipe to unlock. Sometimes, I am unable to pull down the down the bar to unlock the phone. It will go down about halfway and shake a little. I have to set the phone down for 30 seconds and try again. After a few tries, it will finally unlock. This was happening with 2.1 even after hard resets. It is still happening with 2.2 and I did a hard reset this morning. I have tried multiple G-sensor calibrations. I think the hardware is fine but I have no idea why the phone acts up. It was great when I first got it. A few minutes ago, I tried to make a phone call and couldn't dial a 7. I would press a 7 and it would display a 4. I do have a Clarivue screen protector on but I doubt that would be causing any issues. I have the following apps installed and have never installed a task killer. I had more apps but I just did a hard reset and this is what I installed so far: AndChat (always running in background) ASTRO file manager Audio Manager Beautful Widgets Swype 1.56 gReader (NewsRob before that) Touchdown for Exchange Frodo64 Twitter After my last hard reset, I installed AppBrain and the phone immediately started acting up. I installed AppBrain and it got somewhat better but I am still powering off/on about every 15 minutes. Also, the phone is pretty much unusable when laid down on a flat surface. During lunch, I lay the phone down and try to go to websites and it will start scrolling on it's own. It works better when I have the phone in my hand. Should I take this back to the store to see if they can help? They'll probably do a hard reset which has been done numerous times. Or is there anything else I can do?
