My Samsung Charge Drops the connection to 4G and will not reconnect unless it is rebooted. It isn't the signal as I have very good signal strength, as measured by an Anritsu BTS Master spectrum analyzer with LTE software measurements. It is really starting to irritate me. Anyone have a solution to this? I suspect it's the phone, so any i510 firmware updates in the works for this or should I take the phone back and get a different device?
