For the S25? Sure... Because they shouldn't ask for the device until the S25 arrives, and then they give you some time to transfer things over before returning the device. I'd assume the stable version would be out by then. But even if it's not. It's still official Samsung software, so they can't invalidate the trade in.
I'm going to reverse mine back to original last thing I want them to say is trade in is invalidated. So I'll be rolling mine back to on ui 6 which is what the phone came with
Yes it will be fine. As long as it meets the required condition - ie. Working, no excessive damage, no screen issues, then all is good. The good handsets are all reconditioned and firmware flashed in any case.
