Last year was a turning point for OnePlus in regards to updates. The OnePlus 6T launched with Android 9 Pie pre-installed, while the OnePlus 5, 5T, and 6 received the update by the end of the year. It took until May 2019 for the OnePlus 3 and 3T to get Pie, but it’s a miracle the phones received their third major Android updates in the first place.
Expect the OnePlus 7 Pro to get first dibs on Android 10, followed by the OnePlus 6 and 6T. It’s a toss-up with the OnePlus 5 and 5T, since both phones already received two major Android updates. Perhaps OnePlus will surprise everyone and update the two 2017 flagships with the newest version of Android, even if the waiting game might be a much longer one
