Yesterday I had 4g connection in my area on my samsung galaxy s3 and it started losing connectivity because it would show 4g but I couldn't load web pages or use apps. I called sprint and told them my issue and thet had me update the profile and firmware and also change mobile network to CDMA which only gives me a 3g connection. I then changed it back to LTE and reboot the phone and now it doesn't have no 4g connection! It doesn't even connect to 3g anymore. So now I'm stuck in CDMA mode. Has anyone had this issue? Please help me out
