OxygenOS 4.1.7 removes Hangouts from the OnePlus 3 and 3T, adds battery improvements
First off, Hangouts is going away as per Google's request. OnePlus 3 and 3T owners will have the app removed if they've never updated it on Play Store. Those who wish to keep it will have to update Hangouts before installing OxygenOS 4.1.7.
Besides the bug fixes mentioned earlier, a few improvements are part of the update too, including enhanced system fluidity, battery optimizations, as well as the latest August security patch.
OxygenOS 4.1.7 is pushed OTA (over the air) in stages, which means it will initially reach a small percentage of users in the first few days. A broader rollout will begin soon afterward if nothing wrong happens.
