LG G4 stuck on airplane mode?

[AC Question]

My Lg G4 is less than a week old using T-Mobile and today when I tried to make a call a message popped up asking me to turn airplane mode off. My airplane mode is off my wi-fi is on. I tried to turn airplane mode on and off. Restarted the phone, pulled the battery and sim card and its still stuck on airplane mode. Please help.

LG G4, on Sprint, but having the identical issue. Did everything you did, plus a factory reset with no luck. Read on XDA that this is a known LG G4 but and hardware has to be replaced...?
