Just got my dx from Verizon last week and did the update to 2.2. My phone will ramdomly shut down and restart and it always seems to be when my screen is in landscape mode. Also, with Auto Rotate enabled seems to make the Display under battery manager the biggest drainer. I turned Auto Rotate off and now the display is in second place for battery drainage. Going to see if unchecking Auto Rotate helps fix the reboot issue.....has anyone else experienced this? Thaks for the help and sorry if this has already been addressed.
