Anyone who paid attention to this year's Google I/O will remember that OnePlus was one of the announced partners who had all promised to speed up the Android upgrade issue that's plagued the system for so long. While many assumed the OnePlus 6 would be getting the full force of Android P (along with various beta versions), it's going beyond that. The OnePlus 5 and 5T were announced back in May, but today OnePlus has confirmed the next version of Android will hit the OnePlus 3 and 3T.
No time frame has been announced for the rollout, but OnePlus has confirmed that Android P would be coming to the 6 first, followed by the 5 and 5T, and then the 3 and 3T. More updates are promised to come in the coming months, but the company notes that thanks to feedback from beta participants progress with developing an Android P-centric version of Oxygen OS has been "greatly accelerated".
According to OnePlus this decision means the company will be using its resources to focus on the Android P upgrade, instead of upgrading the 3 and 3T to Android 8.1. So it's bad news if you really wanted the newer version of Android Oreo on your device, but the upside is you get a better version of Android.
This news comes just over a month after OnePlus promised three years of support for each of its devices (two years of Android updates and one further year of security updates). So given the OnePlus 3 and 3T's 2016 release date this news isn't that unexpected. It's nicer to get proper confirmation, though, and means anyone still rocking the phones will probably get it sooner rather than later.
