1. The stable One UI 5 hasn't released yet and so anything related to One UI 5 would be in beta form. That means the major version should be 'Z' instead of 'C'.
2. Samsung won't spend in developing One UI 5 from scratch for every device. This would be very inefficient and Samsung has to spend a lot of money. Instead, testing a firmware once the stable One UI 5 releases is very efficient and easy.
3. Last years rumors speculated that One UI 3.1.1 will be available for more devices, but that never happed as One UI 4 took it's place. It might happen that Samsung wanted to change this. Also, the Android version is getting updates from 12 to 12.1.
4. It is practically impossible for samsung to test the firmware so frequently as we have seen for this and other devices like F22, M42, A51, A52, etc as the testing is in Beta phase.
5. One UI 5 for galaxy S22 Ultra has just started and devices like A52 has been tested weeks before that.
However, no one can confirm other than Samsung. If my speculation is true, the update might arrive in September itself for some devices, and in October/November for others.
If that's One UI 5, it might arrive in November/December.
Man looks like you did the framework numbers study (even I did that to decrypt framework version ), and Stable one ui 5 for S22 Series by end of year, yes mostly (s21 , s20 may get beta soon)
Btw if Samsung pays individual attention even 1% towards all devices with 1% care , most issues which occur because of careless unoptimized buggy software won't occur !
