maveshank, Dec 30, 2018 : Dear team, I bought a oneplus6t McLaren edition almost 2 weeks back. The ringtone option is not working and the phone only vibrates all the time. I tried everything including the use of slider button. But nothing works. Everything else works perfectly including 'Mefia' and ' Alarm'. only ringtones don't work. The ringtone option is not even getting highlighted. Screenshots attached. Please advice.
