Is anyone else having any issues keeping a connection to LTE? Mine doesn't hold it worth anything. I can LTE off them back on and it doesn't change but if I turn the cell connection off then back on it will connect. Sometimes it will last for 20 minutes and other times it goes right back to 3G. I'm going to try a restore and see if that fixes it. Just wondering if anyone else has had this issue. I really don't want to swap it out so I hope the restore will fix it.
