So I have had really no problems with my Esteem since I bought it on Sept 30th until the last 2 days. Two days ago I was holding my phone and I believe the screen was off and I heard the 'Hello, Hello, Hello' sound, and the screen was blank when it played the sound and I though uh oh, it just rebooted. But it did not reboot, in fact it was off and I had to turn it back on. It happened again last night while the screen was on but the screen went off and again I heard the bootup sound, nothing on screen and it was off again. So its not actually rebooting but turning off. I am rooted, 8gb Sandisk SD card, extended battery, prl 3019, ZVB update and I have Go Launcher, Esteem optimizer, and the only widgets running are Check It Off Pro (todo list), Clarus Widgets (battery/wifi info) and Minimilistic Text (clock widget). I did have my phone reboot twice last week but it was after I updated G Launcher, went back to previous version and have had no reboots since, except for the power offs. So I guess I am going to see how long this happens before I do anything like reset to factory and see if this ZVC update comes at the end of the month. Just wondering if anyone else has seen any problem like this?
