Is it good to upgrade to s25 from s21 fe?I don't like the cameras in s21 fe and heard 25 also has some problems with cameras. In the same budget, I can go for iphone 16 pta approved. Which one should I buy?

Does anyone got an update to one ui 7 in pakistan if u have s21 fe?many people have already got it, I don't know why they are delaying it so much.
