Samsung with one ui 7 update

What's special in one Ui 2 .. why it's better then one Ui ? Which is the extra features ? Why people want it so badly ?

Anyone having internet issues? I face some sudden internet network drop issue .

Camera 25mp issue fixed .. check yours.

after sometime using the update . I don't face any problems. Everything is good . Only the camera in front says 16mp but I don't see any pictures quality drop . I think it's still capture in 25 but shows as 16mp . Hope they will fix this soon.Please...
