I have the 108mp selected, but I just prefer the older pictures I've taken. They just look more detailed and sharper. I need to try to get a side by side snap in the same conditions, but right now I feel let down by the s21u photos as my 3 year old phone has taken much better pictures.
I'm not saying they're totally unusable, but as soon as you tap to zoom, the Samsung photos just look poor. Decent dynamic range, but noisy, muddy details, grainy, oversharpened, fringing on contrasting edges..
Perhaps it'll be better in bright sunlight... *Shrug*
