With the OnePlus 3 being two years old and the updated OnePlus 3T being nearly that old, you don’t see many updates for these former flagship devices any longer and that is par for the course for most manufactures these days. So when an update for an older phone is released, especially one that contains security updates, it gets noticed – or at least it should.
OnePlus has released an update to OxygenOS, their Android variant, for the OP 3 and 3T that brings a handful of fixes as well as the July Android Security Update to these phones. The updated build is OxygenOS 5.0.4 for those keeping score at home and OnePlus is phasing the roll out to devices. That means it could be several more days before all owners see it land on their phone.
