OxygenOS open beta 23/14 introduces new display calibration, watermarks on photos, and a lot of stability improvements.

OnePlus is rolling out the OxygenOS open beta 23/14 to the OnePlus 3 and 3T with several fixes, stability improvements, and feature additions. OnePlus has tweaked the color temperature of the display so the panel now leans more toward sRGB color calibration.

There are several new features as well — the lift-up display UI has picked up a battery indicator, you'll be able to block notifications from apps that are in the app locker, and the contacts pane now has an alphabetical bar. The update also includes the August security patch, and the gallery will now load images faster. You can add a "Shot on OnePlus" watermark to your images by enabling it in the camera settings. OnePlus has also improved the location accuracy for the weather widget.

OnePlus says that some users may experience issues with toggling the flashlight after installing the beta build. A simple restart should fix the issue. As always, if you switch to a beta build, you won't receive updates from the stable channel — you'll have to manually flash a stable build again.
