I've been reading posts on this and still can't seem to find an answer...This is the worst phone ever....I have reset my phone several times, I have deleted all my apps and reloaded them and it's STILL rebooting randomly...and it's usually when I'm on a call or need to make a phone call...I am beyond irritated with this phone and about to go back to my motorola driod until I am able to renew and get a new phone in June...
