One UI 5.1 released for S21 Ultra in other regions but in Pakistan we are still waiting for it even feb security patch has not been released yet. Pathetic services by Samsung Pakistan.
For those constantly posting about Samsung Goodlock app, you can use Goodlock modules by downloading their apks and using a 3rd party launcher. I am using them all for the last 2 years and they make you phone extremely fun to use.
Nobody knows, even Samsung Pakistan has stopped responding regarding this. S21 FE, S20 series and A series got updates but not the s21 ultra. Pathetic service by Samsung Pakistan.
