I know from the title it sounds like a no brainer, but the 4G emitter is on top of a water tower almost in rock throwing distence. So one would think it would stay in 4G mode so long as I am in the area like at my house. The phone constantly switches back and forth with a period of no data service in between. At first I thought it was due to testing since the 4G service is brand new to the area The official launch was said to be on Dec. 15th but it was actually up about a week before that. I would like to keep the phone from switching back to 3G while I know I am in a 4G area. I know you can turn off LTE but how to keep it on LTE? BTW happy holidays to all!
