it's not a big job, you do not do it, I do not want an Android 10 for it to work, so far all such system updates have been negative on previous "note" models - lesser camera functions and so on. Make sure that the sony controller works under pie !!!
where is the Bluetooth compability list if you do not support all Bluetooth devices?
same for USB
you can design a new logo - "Bluetooth compability to Samsung device"
and sell it to other like Sony ... after they have it on package, you allow to connect.
