OnePlus 3T and OnePlus 3 to get Android O updates by the end of the year10
During an AMA (ask me anything) session held on Reddit today, one of OnePlus' employees said that both of the company's phones from 2016 would be updated to Android O "within this year."
Of course, OnePlus will first have to wait for Google to launch Android O (and give it a proper name, which could be oatmeal cookie). We already know that Android O is Android 8.0, and should be rolled out to select devices starting later this summer. Right now, Android O is available only as a Developer Preview release, and can be installed on Google-branded devices alone.
Hopefully, OnePlus 3T and OnePlus 3 owners won't have to wait too long for their Android O updates. Needless to say, the brand new OnePlus 5 (which is shipping with Android 7.1.1 Nougat out of the box) should also get Android O before 2017 ends.
