Just like other OEMs on beta programs, Andy Rubin’s Essential has also been on its toes to bring Android 8.0 Oreo experience on the Essential Phone. The company launched the Oreo beta program last month, and today it has rolled out the second beta update for Oreo.

The first Oreo beta was comparatively limited in functionality, some Essential Phone users on Beta 1 also reported that the beta was lacking some major Oreo features including Picture-in-Picture, smart text selection, Google Play Protect, and more. Thankfully, the second beta update brings them all to the phone alongside December security patch and performance enhancements.
