While we still have no idea when the official Android Oreo release will come to the Essential Phone, the company is at least releasing another beta update roughly a month after the second beta was released. This latest update is an important one. It’s not bringing cool new features, but it comes with Google’s January security patch which includes fixes for the Spectre and Meltdown exploits as well as other stability and bug fixes. So, if you’ve been using the beta version, you might want to update now. It’s 1GB from Essential’s website or will come as an over-the-air update for those running beta 2 and comes in at approximately 106MB.
