Ok so let's think this through
Samsung replace the phone (they shouldn't as it isn't broken or faulty, regardless of whether you like the software or not)
From that point on, you will never get any updates, either security or OS.
Why?
Because your device will have to download the One UI7 first to being forward the Security Patch at that time.
Is that your ask? No updates ever?
And if so, you won't complain about that?
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
