I haven't been able to find how to turn off the 4G LTE and just use 3G... That way when I'm not in a 4G area, it isn't constantly searching for 4G and draining my battery. Does anyone know where I can do this on GS4? Thanks!
It doesn't give an option for just CDMA(3G)... only gives options for -Global, -LTE/CDMA, AND -GSM/UMTS(what is this?)
Your options are slightly different to those on the i9505, International, phone. This may help explain... I need someone to explain to me what UMTS and HSDPA are and how they are related. I do know they are 3G a
FWIW, my T-Mo (USA) GS4 allows me to disable LTE (thankfully, given that signal is spotty in DC...but solid at home close to Baltimore). However I checked At&t's "GS4 Active", there is no option to disable...I did not check the standard version as I was looking at the active for my at&t account.
