With a little time left before the year is over, OnePlus' engineers and team appear to still be hard at work trying to make Oreo for the OnePlus 5T happen and it looks like they succeeded. The first Open Beta for OxygenOS has rolled for the new 5T and it brings with it the first taste of Oreo on the phone.

If OnePlus' effort with the OP5 is to be taken as a benchmark, the 5T might go from first beta to second beta to release in less than a month, which means we could have stable Oreo on it before the end of January.
