Just picked up a Z3 on swappa. Loving the phone so far. Issue Im having is after getting APN setting from my S6 it connects to 4g lte..but, if I turn on and off wifi or make a call it reverts to 4g and will not go back without a reboot. Reboot and I get 4g lte again. From reading it sounds like this model is missing a band for att. But why will it connect then reconnect. Anyone using this on att and have a fix?
Thanks
