No more official Android version upgrades after Android O

In the interview with @Oliver Z (Head of Product) owners of last year flagship 3/3T models got some answers. We are talking especially about future software updates that'll bring some of the features from the OnePlus 5 flagship device. So, after 3/3T recieve Android O , Open Beta Program will be moving to OnePlus 5. August security patch will be out ''soon'', while OxygenOS 4.5 (OnePlus 5 already have it) will become available in next month or two. Some of the features that can't be implemented from OnePlus 5 to 3/3T are: Reading Mode, Off-screen gestures and DCI-P3 screen calibration (because of hardware differences).
