Hey it is not your phone it is sprint. What ever you do don't call Samsung they will tell you to factory reset. Sucks I called three days ago. If you Google sprint low resolution you will find their community forum with a ton of complaints and they all get the same answer. Sprint is up grading the towers to 4g lte. Now that is true in my case, Des Moines now has it in a large part of the city but a lot of my image quality Sucks at the moment. They say it will go away as they get all things running as it should and truthfully my resolution has gotten better Over the past 24 hours
