We have 2 of these Droid Maxx in the house. They both show horrible 4G signal compared to any of our other phones. Quite a few times, they switch to 1X for data. Again, other phones are not showing this while these do it.
Secondly, one of them also periodically goes to "Emergency Calls Only" mode after a restart. It takes another restart or 2 to get it to work again.
I don't think these are both related, but mentioning them together anyway. Any thoughts or things to try?
