Beta Programme for S10 has ended some time ago, but you still have a chance to let us know if you have anything to say about the Android 10 on Samsung 9! We're still here
The S10 beta started before the S9 beta, and it ended a few weeks ago.
The S10 is now on a stable version, while the S9 remains on beta, currently beta 4.
