Hi,I had this issue with my Z3 on Kitkat, did the clearing of the stamina mode app in all apps and re-enabled and rebooted, and now still not fixed on lollipop 5.0.2. I even used PC Companion and also reset all in backup and restore and shut off google app data backup restore. If I go in a underground subway with no service and come out it sometimes, not always, has all my cell bars but doesn't say 4G or any type of data, just the bars. I need it to know when I turn my screen on to enable mobile data. Thanks!
No, mine has nothing to do with wifi or low battery mode or quick settings.
It's when I go underground on the train. It will go back and forth at stations being on lte, 2g and in between nothing. When I come out of trains a lot it has mobile data off completely even after unlocking.
