Yes they can fix the Autofocus but they need to fix the price. Based on reviews the S20 is over hyped and overpriced. That's what happen when you rush the products.
Maybe u can fix the AF problems, Samsung. But you cannot get rid off the typical Samsung's camera image algorithm that smeared, smudgy details with plasticky looking photos. What a waste of large sensor on a smartphone camera hardware in Ultra variant, which has no advantage over vanilla S20/+, or even its old S10 series.
