Oneplus 3 here
Likewise. Mine is, however, rooted and running a custom ROM. Sure, that means I can't use Android Pay but, since I wouldn't anyway, I've not felt the lack.
The ROM I'm using is this one: https://forum.xda-developers.com/oneplus-3/oneplus-3--3t-cross-device-development/op3-op3t-unofficial-lineageos-14-1-t3588696 from the developer Sultanxda - he provides regular updates based on the upstream changes from both LineageOS and OnePlus.
I would heartily recommend his ROM (and his Android 6 version for the OnePles One)
