I am having signal problems with my HTC Desire 620g. There are locations wherein the phone doesn’t have any signal at all. And the phone never reaches its highest signal. It only displays 2 signal bars most of the time.
I checked my other phone(samsung) on that very same location, but the signal bar is full. I also tried swapping my sim to see if it’s the problem with the sim card, but it’s not. I already did factory reset twice, but I am still encountering the same problem. Any suggestions?
