Just realized a very annoying problem that just seemed to start today. I haven't changed any settings or installed any new apps. If my screen gets locked, either by pressing power or timing out...it cuts the data connection. As soon as I wake it up with the power button or volume rocker (I have nolock installed, have since day one) the data comes right back up. It will come up regardless of it being WiFi or LTE. I have my corporate Email (Exchange on Active Sync) set to push from 7AM to 6PM Monday through Friday, then poll every 1/2 hour on nights/weekends. If it wasn't for push email during the day, I really wouldn't care. Text and phone still works perfectly...but I use this phone for work and personal. Any ideas on settings? I've checked them all...and nothing about turning off data while in lock (I've looked at every power saving/data setting I can think of) Any help...much appreciated! I have restarted the phone a few times today and even pulled the battery. Same thing.
