With this back and forth on updates etc it reminds me of when I used to be heavy into PC's. Nvidia would release video card drivers in beta form, often they would work great, other times not so much but for other users, they'd work just fine. It's the same with Android and OEMs, it works with Android but maybe not exactly your phones board, camera, modem etc. Testing is always best and with OnePlus, they do initial in house testing and if it's green lighted, it was once private beta then it's released as an open beta, once comfortable with mass acceptance, bits and parts or the whole release will go live. We benefit as well as they.
Another example, take your car down to a tire shop and just have them install any old tire.. It won't work, yes it's a tire but the manufacturer has to adopt that compound, size etc to your particular vehicle.
IDK, makes sense to me..
