My new Moto G 4th gen does not stay connected or the search for the next cell tower does not go smoothly. I am an Uber driver so I need to be able to get from one call to another. I often loose my connection during the ride it says “GPS network search” or something like that, my screen changes when I am using Waze from an arrow on the street to a dot beside the street if I get anything at all. Yesterday it just froze up. I need to be able to get to my next call as quickly as possible. Please help.
