I recently updated to Kit Kat and flashed latest firmware and radio. I'm having a problem where data seems to freeze and won't connect at times. I can see the 3G data up and down arrows trying to connect, but it just never makes a connection. I can go into airplane mode and then back to service and it connects right away, usually to LTE, so I'm thinking it has something to do with the switch from 3G to LTE. Super frustrating as I drive around the city a lot for work and sometimes data freezes for 15 minutes or more. Anyone having similar issues?
