Wow. I was amazed to read this. I know that the Samsung Galaxy S8 takes brilliant pictures and the focus always seems pretty close to perfect. I am often torn as to whether the camera on the Google Pixel 2 (which I own) is really more competent than that of the S8 as all the experts claim. So, I had expected the S9 to be even more impressive — especially with the dual rear cameras — one with variable aperture, the first in a phone.
If this autofocus issue is as bad as DPReview claims, and they usually are spot-on on such matters, I am sure that Samsung will try to fix it with a firmware upgrade ahead of the holidays. Otherwise they are going to have their lunch eaten by Apple, Google and the oters.
I just wanted to make sure you had heard about this — since this is important.
