I was wondering if anyone else has been having the same issues as me; starting around last week, some applications just don't work so well with my phone using 4G, and I'm forced to switch to 3G to complete the task. Some repeated tasks I have not been able to complete with 4G would be: updating applications with Google Play (since newest version), updating articles on Flipboard, opening articles on Flipboard, and sometimes opening Facebook. And it's not that my 4G has disconnected or gone to sleep, because I can exit out of the non working app and easily go into many other apps with no network problems, yet returning to these repeated tasks with 4G continues to give me problems.
