Clearing doubts of community members over future software support for the OnePlus 3 and 3T, a senior company executive confirmed in a Q&A session on Friday that both the devices will receive the upcoming Android O, but users shouldn't expect any major OS update after that. "After the OP3/3T have been updated to Android O, we'll start moving the Open Beta Program from OP3/3T to OP5". We'll continue to release security patch updates for the foreseeable future, and offer support for individual application updates.
The OnePlus 3 and 3T are two of the most highly-regarded phones that OnePlus has released to date, and leading up to the announcement of the OnePlus 5, there was some concern surrounding whether or not OnePlus would actually continue to update its older hardware.
So there's been a surge in questions about software support for the OnePlus 3/3T on their forums and they chose to pool a few of them together for some answers.
Oliver says the company dedicates a lot of time during the 1-2 months after a new device is released to iron out/add some of the most requested bugs/features. Another question asks about security updates and they're told that due to a delay in OxygenOS 4.5 for the OP3/3T these security patches for August will be pushed "soon" by themselves and without the big 4.5 update.
The OnePlus 3 was released in the summer of of 2016, while the OnePlus 3T arrived just before the turn of the year.
