Android 12 Developer Preview 2 released for OnePlus 9 and OnePlus 9 Pro.

OnePlus has recently released the Android Developer Preview 2 for the OnePlus 9 and OnePlus 9 Pro, just in time for the official release of Android 12. The new version arrives four months after OnePlus released the first Android 12 developer preview for its 2021 flagship series.

Improved auto-brightness behaviour, faster frame rate performance in graphics-heavy games, enhanced zoom performance, and other improvements are included in Android 12 Developer Preview 2 for the OnePlus 9 series.

In addition, the update includes new widgets that highlight key information from apps at a glance, as well as improvements to the page layout and text and colour presentation to emphasise important details.

There’s a big list of issues, as you’d expect from a developer build. For example, the camera app lacks support for the recently added XPan mode, the scrolling screenshot capability, and call recording in the Google Phone app.
