TachyonQuanta , via OnePlus 7 , Jan 22, 2021 : Oxygen 11 Open Beta 1 update for OnePlus 7 series is a new experience. That's to say, obviously there are minor bugs and glitches. As soon as the installation was over, the system just stop responding for sometime and then it's solved somehow. Afterwards kinda facing a weird glitch on lockscreen. Whether using tap to unlock or the physical button, for a brief moment the lockscreen Just disappears. It occurs very often. So, without unlocking the phone you can actually glimpse what's on the other side, sometime it's longer than a glimpse.
