Rockin_Sam, Mar 8, 2019 : After the latest update there is a problem with calls, gestures and facelock After the update whenever someone call me on my OnePlus 6T the phone rings and the number and answer or cut buttons are not displayed immediately. after waiting for 5 to 10 seconds it gets displayed. The screen gestures like V for flash light have also become less responsive that previous updates. The face lock was however not working from beginning itself as my brother (not a twin) could open phone with face lock. But in between somewhere the face lock improved and my brother tried to open and it didn't unlock phone. But I think after last couple of update it has gone back to how it was. Till now didn't find threads will similar problem. I hope someone will see this and get this corrected in next update.
