Have an sgh I337 att galaxy 4,
My issue and question, i have had this phone for a while it has seen a LOT of abuse, have replaced busted screen 2 times!
with that in mind latest issue and yes did factory reset camera shows nothing on screen and says a error, also wifi will not turn on at all slide to turn never connects goes to off position, ni assume due to many drops the board had said enuff, !
now my question if i buy a new logic board / mother board will i have issues connecting to my provider? AT&T, imei # and so forth, or will popping in my sim negate that issue?
