The Essential Phone gets a tasty upgrade today to Android 8.1 Oreo.

The software update was announced in a tweet from Essential Tuesday, telling customers that it should be available to install from the phone itself. The phone was previously on Android 7.1.1 Nougat, and is skipping the Android 8.0 edition of Oreo due to stability issues the company discovered and announced in January.
