My phone has started to drop the mobile network. Even when I have full bars 50% of the time I have no Internet. I live in a 4g lte area, so I don't think it's a signal issue. My wife's galaxy s2 gets 4g just fine when they are side be side. I have tried stock and custom roms with no luck. Is there a known fix? Is this something that all 4g lte phones do right now? I will ebay this phone and buy a gs3 if that would help.
