Android 8.1 Oreo arrived to the OnePlus 5 via a beta update quite recently, and the same has just happened for the OnePlus 5T. OxygenOS Open Beta 4 has landed to the OnePlus 5T, bringing Android 8.1 Oreo along with it. Do keep in mind that this update may not be available to all of you who are running OxygenOS Beta build, but you should get it in the near future, if you haven't already, while you can also manually flash it, of course.
Now, as far as the changelog is concerned, it's almost identical for both the OnePlus 5 and OnePlus 5T, the only difference comes to navigation gestures which are not included in the update for the OnePlus 5. Aside from bringing Android 8.1 Oreo to the OnePlus 5T, OxygenOS Open Beta 4 also brings a new gesture along with it, the 'auto pick up gesture', which will let you answer an incoming call by raining the phone to your ear, without pressing any buttons or anything of the sort. This update also brings general bug fixes and improvements, as pretty much every other update. The company has also added more clock styles for ambient display with this update, while OnePlus also optimized full-screen gestures in this update, gestures that were released to the device a while back. The OxygenOS Open Beta 4 update also brings a new Android security patch to the OnePlus 5T, a security patch for February 2018.
On top of that, this update also brings various new optimizations for 'gaming mode', the company claims that this mode will not bring an even more immersive gaming experience, as it can now pause adaptive brightness and includes power saving options. The OnePlus Switch app will also arrive to your handset with this update, and it should make migrating to a new device a lot easier. It is worth noting that the OxygenOS Open Beta 4 update for the OnePlus 5T weighs about 1.6GB, and if you're eager to get it, you can always manually flash it, you can download the necessary files by following this link. The OnePlus 5T received navigation gestures via a beta update a while back, as already mentioned, and the next stable OxygenOS update for the device will probably include those gestures as well.
