Chinese OnePlus 6 received an update to the HydrogenOS 5.1.6 a few days ago that added some of the features that were absent at launch and improved with overall system stability. Now, the international OxygenOS 5.1.6 OTA update has arrived.
This update brings Portrait Mode for the front camera and preview for Light Bokeh effect in Portrait Mode for the rear camera.
Other noteworthy additions include the DND (Do Not Disturb) schedule, battery percentage in the status bar, dual 4G network support in SIM and Network Settings and smart answering for Bluetooth devices. Smart answer allows the automatic answering of incoming calls when being connected to a Bluetooth earphone device.
Many bugs like the issue with ringtone volume are no more. The update brings improved sound quality, optimized call quality, power optimizations and improved system stability. Hopefully, after this latest update few bugs will be left.
