I have a Samsung Galaxy j3 2016 (root device)
His rom is custom: Team OctOS Nougat ROM . My problem is that the signal on the [Internet - Data] has long been making me the mark "x" when I open it and for that i cant access internet no way. Some times i dont have it, but most of the day it comes back. Does anyone know why it happens and what can I do ?. I thought it was a matter of Vodafone which blocks or track it or there is a technical problem of mine.?. I have tried many things like restore apn settings, or factory settings. I cant use ether a secret code because it shows me two errors: "Unkown Device" and IMEI problem.
