I fixed my hacked phone last night and found the options to change the data carrier type to 5G for example. It had many option too Change the call settings and also all internet settings and DNS settings. I am convinced it was on this menu before, under advanced settings and it is no longer there at all. Someone must have remotely flashed my phone or something. Please help me find an answer, I NEED my phone back to normal ASAP. It literally fixed absolutely everything for a while.
