Very new to Android phones. Why when I am in a 4G area and the small 4G icon appears at the top of my phone does it disappear and then it has a 3G icon ? I could understand that if I left the 4G area that it might change to a 3G or a 1x but why would it change if I dont move ? Also in settings/wireless&networks/mobile networks / network mode should I be in LTE/CDMA or CDMA only to stay on 4G ? Not concerned about power useage as I charge in the car and at work - very O C D and like to stay in 4G all the time as I paid for a 4G phone. So how do I always stay in 4G?
Next. Is there a better camera operating system app than the one that comes free wth the phone ? What is the absolute best NON FREE app that I can pay for to fully utilize the camera functions of my phone ?
Any and all assistance is greatly appreciated ! Scott.
