OnePlus 3 and 3T more than 24 months old. They come with Snapdragon 820 and 821-powered devices have both seen daylight running Android 6.0 Marshmallow out the box, which made their Nougat and Oreo promotions feel… refreshingly normal.
Last week the company has released the latest Android security patch and Including our camera improvements, the OxygenOS 5.0.4 update for OnePlus 3 and 3T worldwide. After internal discussions and evaluation, we have decided to focus our development resources on the Android P project instead of upgrading the device to Android 8.1, so that we can offer more exciting features and improvements for our OnePlus 3 and 3T users.
OnePlus will look to update the OnePlus 6 first, then the 5 and 5T, meaning the earliest you can reasonably expect the 3 and 3T to do the official Android P dance is probably during the early stages of next year.
