Am I missing something here? I have this feature in oneplus 3t since December if I remember!!
I did not get this update. But, was able to use Airtel VoLTE.
At first I was excited to get this feature but after a few hours I had to disable it as it's just annoyingly fast. I only wanted to check the time and notifications but I accidently unlocked my phone
damn waiting for it to come in stable update soon
Face unlock working superrrrrr . thx for oneplus team...
