I upgraded to the gs7 from gs5 and i have noticed lesser mobile data coverage. Previously, with my gs5, most of the time i would have a couple bars of 4g. Now i have 3g a lot of the time and have occasionally dropped data coverage for several minutes. We do live in the country so i thought maybe we lost a tower but my wife, with a gs6, is pretty consistently in 4g. Is there anything i can do without getting a booster box?
