OnePlus 5 and 5T are getting Screen recorder, Fnatic mode, more in latest update0
First and foremost, the latest OxygenOS update adds the Screen recorder feature for OnePlus 5 and 5T users, which can be found in the Settings / Edit / Screen Recorder. Also, OnePlus has decided to include a Quick reply option in landscape mode, which is accessible by heading to Settings / Utilities / Quick reply in landscape mode.
The official changelog also mentions some general bug fixes and system improvements, but we're not sure whether or not these will be noticeable. However, we're 100% certain that OnePlus 5 and 5T users will notice the new Fnatic mode aimed at gamers. The new feature can be enabled from the Settings / Utilities / Gaming mode.
Last but not least, the new update fixes an issue with Speed Dial, which affects both OnePlus 5 and 5T phones. Keep in mind that this OTA (over the air) update is rolled out in stages, which means it is currently available to a small percentage of users. A broader rollout will start in a few days though.
