One month after launching the first Android 11 Developer Preview, Google has an update ready to go.

Android 11 Developer Preview 2 is now available. Just as with the previous update, this new version is intended only for developers because it's not quite ready for daily use. It's also still limited to the Pixel 2, 3, 3a, and 4 devices.

If you've got one of those Pixel phones and want to install Android 11 Developer Preview 2, you can use Google's Android Flash Tool or manually flash the update if you'd prefer. Folks who are already running Android Developer Preview 1 or Preview 1.1 can get this new update over the air.

Improvements packed into this Android 11 Developer Preview 2 update include a new hinge angle sensor for foldables. This API will allow foldable phones to get the precise hinge angle that the phone is at, enabling developers to create adaptive experiences for their apps.

Also packed into the update are improvements to call screening. We already know that better STIR/SHAKEN support is coming with Android 11, but now call screening apps can also report the reason that a call was rejected and customize a system-provided post-call screen to let you do things like mark a call as spam or add a number to your contacts. 

A new 5G State API will let developers quickly check to see if the phone is on a 5G New Radio or Non-Standalone network, meaning apps can offer a custom 5G experience or branding. There's also improved support for variable refresh rates, letting apps and games set a preferred frame rate, and a "Resume on reboot" feature will let apps resume normal functions right away after the device reboots, which could come in handy for those times your phone installs a new OTA update in the middle of the night.

Google says that the final Android 11 update should arrive in late Q3 2020. There will be several more Developer Previews and Beta Releases between now and then, though, with the next one expected to hit in mid-April.
