OnePlus is looking to bring the always-on display to its phones in the near future. While it hs been in the user's wishlist for months, OnePlus will finally bring Always-On Display with OxygenOS 11 update later this year. The feature was teased by Pete Lau in a recent tweet. Take note that Lau dies not clearly point that the feature is coming but the conclusion can be made pretty clearly.

OnePlus previously committed to being the Always-On Display feature to its OnePlus phones. Now, with Android 11-based OxygenOS 11, the company will bring the feature to light. It has been the community's most demanded feature that we're all looking forward to. To be fair, coming from a Samsung phone, I personally find the Always-On Display pretty useful, and not having it on my OnePlus 7T is plain sad.
