The OnePlus 5 and 5T will receive Oreo by the end of the year
The OnePlus 5T was officially announced yesterday and will be launched on November 21. The Chinese company, however, has confirmed that the new device will ship with Android Nougat, with the Oreo beta set for release by the end of the year.
OnePlus already has an active Oreo beta program, but it's only open to users of the OnePlus 3 and 3T, which is a bit baffling as one would expect newer devices to get priority.
The OnePlus 5 was launched way back in May, so there are no issues about it receiving Oreo so late—most flagships are yet to get the update in any case. The 5T, on the other hand, comes three months after Oreo was released in August, so it makes no sense that it launches on Nougat. OnePlus has a policy of delivering two major updates, so this looks like a ploy by the company to ensure that the 5T receives its last major update—Android P—in about a year, instead of the two-year window that the "two major updates" clause would imply normally.
This isn't without precedence anyways, as the OnePlus 3T that was launched about a year ago will also have Oreo as its last major update.
The OnePlus 5 will receive its first taste of Oreo by the end of November, with the 5T to follow a month after. Both devices are expected to receive final stable Oreo updates early next year.
