The OnePlus 6T is set to debut later today, but we're still waiting for last year's handsets to get the long-awaited upgrade to Android Pie. While there's still no news on a rollout timetable, it has been confirmed that OnePlus is sending out an update that adds support for Project Treble to both phones. Hopefully that means the update cycle will speed up.
For those that don't know, Project Treble is an initiative by Google to try and speed up the process of updating third party handsets, because Android phones are notoriously bad for getting new updates in a timely manner. It does this by enabling phone makers to boot a generic Android image, and in theory means they can speed up the update process.
OnePlus already offers Treble support on the 6, and has been testing a beta version of it on the 5 and 5T for a while now. This is the stable version, coming as part of OxygenOS 5.1.6, and is bundled with improved stability for Bluetooth calls and the latest Android security updates. As is the way with updates the latest version is rolling out in batches to make sure there are no serious bugs in the system. That said it's expected 5 and 5T owners will be able to update within a few days. [OnePlus via Ubergizmo]
