Does anyone experience reception issues on the sprint network with their S4's? I'm debating on upgrading to the S4 with sprint or move to a different carrier. My current phone, SG II, just plain sucks as far as data and phone reception but had no bad issues with my prior htc phone. I know sprint service isn't all the great to begin with but I've found from other reviews the SGII just sucks. Wondering if the 4 is any better with the antennas.
