Samsung Galaxy S4 Baseband I337UCUAMF3 never updates past 4.2.2
Can someone please explain, and give the whole truth, on why my phone never gets any updates past 4.2.2? I have read many things and it seems that, besides the obvious that AT&T is the worst at getting phone upgrades, once you get AMF3 you are stuck with it at 4.2.2 because it is know that other versions have issues.
I have yet to understand why it is so difficult to get a new version. I am almost to the point of doing a factory reset and then attempting the upgrade again. If that does not work I will either place a custome rom on the phone or just wait for the contract to be up and leave AT&T and save me some money with another company.
