Samsung has officially declared One UI 3.0 Beta program has closed for Galaxy Note 20 & Note 20 Ultra smartphones. It is the indication of the stable version is near to launch. The Galaxy Note 20 series has received third beta version in the home country when the company announced the closing of the beta program. The Galaxy S20 users still not received any such announcement but I think, it may happen today or tomorrow. Since the beginning of October, Samsung has been opened One UI 3.0 Beta program for many flagship devices. Now, it is a perfect time to release the stable Android 11 version for all the users.
It is not confirmed when the One UI 3.0 stable version will rollout for end users. The official Galaxy Note & Fold Moderator gives hint that the last beta version was near to stable version. Further, he added the company is now giving final hands on the code and reviewing small details. The Samsung Malaysia website has already confirmed stable Android 11 version could release at the end of November or in the beginning of December.
The answer by the official Beta Operation Manager is for South Korean users, so the users in the other countries may receive another beta updates for the Note 20 series. I guess, when Samsung rollout the latest version, then Galaxy S20 series will receive it first, and later it could come to Galaxy Note 20 lineup.
The previous Galaxy Note 10, Galaxy S10, Galaxy Z Flip & Z Fold 2 are still enjoying beta versions, so company might not end soon beta program for those devices. When I receive any official date for stable version, I will inform you, so stay tuned.
