I upgraded to Ics and now i lose 4g frequently sometimes losing signal altogether . Has anyone else had this since upgrade . I already cleared out caches and have to restart phone just to get signal at times . This is not a tower problem cause i live in jersey and travel to ny everyday and it happens here and there no area is safe. Whats up verizon. also my contacts act funny you hit one name and another dials also heat from phone and bat problems all since update.
