Have a galaxy S5 and hubby has Samsung Stellar. Our phones convert to 1x upon making or receiving phone calls. This has just started for us within the last 3 months. Problem is we drop calls with 1x and need to go outside and walk around in order to make calls. Have a friend 3 miles away that has the same issue with an Apple phone. Both of us have Verizon. Would really love some help or fix if there is one.
