After going Sprint 6 times in one week and waiting hours ,and being told nothing wrong with phone after reset and diagnosis tests because phone been freezing for weeks I figure out problem. I bought a generic charger at Walmart and it was causing phone to get so hot the screen would stop working. When I would unplug from it and use the charger that came with phone it would work great everytime... Throwing away this charging and sticking with Sprint product for this expense phone.
