[Q] TMO GS4 Network Modes on AT&T Network
So I recently got a T-Mobile GS4 for use on AT&T. I have set up the APNs, etc. and everything seems to be working, except for one annoying thing:
The device seems to be reverting it's Network Mode to WCDMA preferred instead of LTE/GSM Auto. I have tried setting this in Settings as well as in the Testing mode menu and it will not stick.
This happens every time the phone is booted, as well as when a call is made. When the phone is booted, it takes a long time to connect to the network, and when it finally does it is set to WCDMA preferred. I can then change it manually to be LTE/GSM auto.
When I make a call, the network drops from LTE to H/H+ as expected. However, after the call is completed, the network connection drops entirely and reconnects a short time thereafter but on WCDMA preferred.
Has anyone else experienced this issue, or have any ideas? If it makes any difference, I am running the latest CM10.2 for jfltetmo, without any other modifications.
Thanks in advance!
EDIT: I should add that the IMEI on file with AT&T is indeed for an AT&T LTE phone.
