OPPO has ushered in a new ColorOS 6 update for the new Reno flagship. The update with version number PCCM00-11-A.16 adds new full-screen gesture controls to the device. 
The various gesture controls include swiping from both sides of the display to carry out specific tasks. Swiping from the left or right side of the screen inward takes you to the previous app. When you swipe upwards from the bottom of the screen, it takes you to the home screen. While to open up recent apps, you swipe upwards from the bottom and then pause at the middle.

The Gesture navigation method is an alternative to the use of virtual buttons that have been implemented on Android phones for a while now but continues to get improvements, including the latest Andriod 9.0 Pie. The Reno runs on ColorOS 6.0 based on Android 9.0 Pie and already has some gesture control features but the update seems to bring some added gestures. Gesture buttons bring ease to phone operation when you get a good grasp of all the supported gestures. It also allows for one-handed operation easier.
