Kind of the same problem here. This is what I have found with my 32 g iphone 5.
Start with 3 bars of LTE.
As soon as a dial or receive a call it reverts to 4 bars of 4g.
After being on the phone for 4-5 minutes it reverts to 4 bars of EDGE. (this has been tested mutiple times. Also while on the phone with ATT Tech support) (NO MOVING AROUND SITING IN THE SAME SPOT AS WHEN THE CALL WAS MADE)
As soon as the phone call is ended. The phone returns to 4g within 30 seconds or so.
Then within a minute the phone returns back to LTE.
Any ideas on this?
