YES, YES, AND YES!!! So glad someone has created this post! I got my 2nd Charge last week Tuesday. The original that I lur chased from Verizon on the 14th of August CONSTANTLY Rebooted and froze! I did about 3-5 Factory Resets! On top of that, I was rooted and I flashed two different ROMS and still had the same issue! I un-rooted and it STILL randomly booted after freezing or lagging. My new Charge didn't start doing that until a few days after getting it. I finally called CS over the weekend I think it was and the guy told me it was probably because of how many apps I have and some apps themselves. I told him I was using thee exact same apps I had on my MyTouch 4G when I was with T-mobile and that never happened with them.
He told me to uninstall all my apps and wipe my SD Card. Also, to re-install an app one-by-one and that way I could keep track and see which was causing the issue. I backed up my SD Card before wiping it. I did a Factory Reset and installed my apps one at a time. I also downloaded another virus app protector as a backup to the Lookout Mobile.
It's been a week now and my phone hasn't Rebooted since doing that. (FINGERS CROSSED!) I also didn't move any of my apps to my SD Card this time like I usually do. To say if I had a corrupted app, or corrupt app on my SD CARD, IDK for sure. I'm just thankful it's not happening anymore.
***I'll be glad when we do get the official GB Update because I have yet to enjoy the snappiness and speed of this device because there's a little delay when switching apps or doing other functions. And I choose not to root this phone right now...***
