[Q] Force S2 to 3G Networks
I am using a Galaxy S2 Skyrocket on the Dirty Unicorn
rom and I was wondering how I can force my network to 3G. I have Straight Talk on AT&T and a very good LTE 4G signal but it drains my battery very quickly and I don't really need the speed of LTE and the speed of 3G works fine for the things I do.
I've tried in the Mobile Network settings to switch it to GSM/WCDMA preferred but it always immediately switches back to LTE/GSM/WCDMA mode and connects to LTE. The use only 2G networks option does not work either as it immediately gets turned back off as soon as you turn it on.
Using *#*#4636*#*# to switch the mode to WCDMA preferred or GSM preferred does not work either as it also switches back to LTE immediately after.
Is it possible to force the phone to 3G networks? On my old captivate samsung phone on a 4.2 JB rom, it was doable and it worked on 3G fine (even being a 4G enabled phone).
