What you are saying makes no sense and asking to get it released any sooner isn't going to speed up the process. Sorry to say, we aren't Samsung.
What we currently have, and experienced so far is internal testing and beta testing. So far beta has only gone out to a select few, hence the terminology "beta". It's not public, you have to opt in (samsung members) and take the risks etc., it's buggy. If it went to everyone it'll have millions complaining it's buggy and not working correctly. If you want it working 100% wait for the official release as an OTA or update via ODIN when it appears.
As for it being in beta so far, It will come to other models, as did one ui 4 beta. Give it time.
I am g988b (exynos) so probably be the last to get it, but patience. I experienced it with one ui 4 beta.
Thanks to those on this thread that have uploaded the files so far and i look forward to seeing it for more models!
This photo is from samsung members, and the s21. So we're not alone. Patience......
Luckily we can snap the "ota/firmware file" and update via zip or adb as seen in this thread. I'm sure once it's available for other models links will appear on here.
