This is why it doesn’t really come as a surprise to learn that OnePlus will be done with the OnePlus 3 and 3T after the Android O update. According to a post on the OnePlus forums, the company’s Head of Product Oliver Z revealed and confirmed that Android O will be the last major Android update for the OnePlus 3 and 3T.
However this doesn’t mean that OnePlus will be abandoning either handset. Both phones will still receive updates such as security patches from time to time, but don’t expect them to receive the next major Android update, which assuming Google keeps to their naming scheme should be Android P and should be released in 2018.
According to Oliver Z, “Android O is going to be the last Android version update we’ll release for OP3/3T. We’ll continue to release security patch updates for the foreseeable future, and offer support for individual application updates.” That being said, it is unclear when Android O will be officially released. We heard a rumor last week that suggested that it could be this week, but so far we haven’t seen anything.
