I have a Google Samsung Galaxy Nexus phone. It is a little over two months old and about a week ago I got the 4.2 update automatically. When I had Jelly Bean..version 4.1 whatever, it worked smoothly, without a single issue. Since this update here have been the problems. The phone has started rebooting...not all the time, but two or three times a day. This is very annoying, as I have been using the phone and it has just suddenly decided to reboot. The phone refuses to keep and store my voice mail number. Now every time I have a voice mail, I have to manually key in the number. It asks to store it, and I try to get it to do that, but when it does the stupid reboot, (see above) it will then lose the number again. My battery life has been cut by about a third. I dont know what systems this is running, but whatever it is, it eats at my already rather meager battery life. Is there ANY way to revert to the old Jelly Bean? I dont want to go all the way back to ICS, but if this keeps up I am going to have to. Any advice?
