Both the Motorola Moto Z2 Force and Sony Xperia XA2 are currently installed with Android 8.0 Oreo. While the former got this OS via a software update, the latter came with the OS out of the box.
The two companies’ take on Android Oreo isn’t as messed up as what you’d find on other [mostly] Chinese vendors like Xiaomi, Huawei and co, but still, if you are looking for something that offers even more to what is already an amazing software experience, LineageOS 15.1 has all your answers.

It gets even better since LineageOS 15.1 is based on the newer Oreo 8.1 and not what you find in the duo, yet the two are unlikely to receive the official update to Oreo 8.1 from their respective vendors.
Also, it’s worth noting that LineageOS 16, which will be based on Android P, will more than likely add support for these two devices and many others when it arrives.
