You are aware of the horrendous issues the S21 Ultra landed with initially right? Especially the 108MP mode. There's been a literal potential of 3 years of optimising and tweaking the camera on the S21 Ultra compared to the 1.5 months on the S24 Ultra. It's not an excuse, but to try compare the two and say the S21 Ultra was perfect at launch is an outright lie. The S24 Ultra camera hasn't had anywhere near the issues I can recall compared to the S21 Ultra and for the most part, everything is better, zoom, low light, details, colours, clarity. Yes there are some flaws and weaknesses in some areas, such as a digital display in 200MP mode, but there's never been a launch where any of the 108MP or 200MP mode cameras were perfect.
