I'm experiencing intermittent issues on my ATT ip5 in regards to LTE covered areas. The issue is that the phone will sometimes "dumb out" and basically won't connect to LTE even though it's fully available. The LTE toggle in settings usually clears up the issue. Switching off then back on allows it to fully reconnect. Another issue is coming out of airplane mode, it will sometimes take a long time to connect to a network. I never had this kind of wait time on my iphone 4. Also sometimes coming out of airplane mode, it will not connect to LTE without a toggle reset. Finally, from my experience it seems that there are bugs between the communication of the LTE/gsm chip and the phone's software. It seems like it does not properly search/acquire network connectivity in all locations. In some situations, it seems as though it will continue trying to connect to the last known cell tower instead of automatically refreshing and connecting to the closest one. Any similar issues that people are experiencing, please leave a comment below.
