I purchased new S9 phone on 12/08.
So far into 16 days of using, I found that the Video recording especially with front camera is very poor in this phone.
It continuously adjusts focus and the images turn blurry.
This is a big issue when Video chatting as the other person constantly sees the blurring when I move.
This shouldn't be the case with the flagship phone of Samsung when even the mid-range smart phones don't have this issue.
My video doesn't last longer than about 5 seconds and then keeps shutting off so basically it's worthless!
