Mine blurs the outer edges and makes macro shots difficult. I've had it for about a year and it's always been like this so I've just assumed that's Samsung being weird. I've shot pictures of all kinds with this phone and haven't been impressed with it. (Taking pics for an Amazon review)
Yeah, I´ve got the same issue!
zoom with 0,6 and over 3,0x is working well and sharp.
Just 1x and 2x zoom is very blurry.
Tapping at the left side of the phone will fix it for current camera usage
mine too on s21 ultra. why samsung didn't give any explanation to this case, for such expensive phone?
