My default and Dolphin browser have all of sudden quit working. They work fine over wi-fi but a no go once on 3G. What is strange is that I can go to the Play Store or any app that requires an internet connection and everything works fine. I'm at a loss. I took the phone to AT&T and they said they have never seen this on an android phone before. I've done a battery pull also to no effect. Can anyone please give me any ideas. My only other option is a factory reset which of course I want to avoid. Thanks.
