OnePlus releases screen recorder for the 6/6T
OxygenOS 9.0.7 for the 6 and 9.0.15 for the 6T both come with security patches June 2019. These builds bring the Screen Recorder feature which was introduced with the 7 Pro. It can be accessed from Quick Settings.
The new firmware also improves the screen rotation and brings in VoLTE/VoWiFi support for Danish operator Telia.
However, neither of the phones gets Zen Mode which is currently available to users on the beta channel.
These updates are currently coming OTA to select users, and a broader rollout will start in a few days if all goes smoothly.
