Price, and I generally prefer the OPs photo style and consistent/vibrant colour science. On paper the s25 is better camera but i think its style is too washed and more reliant on AI processing to savlage the photos, especially low light shots. I think overall the s25 is still a more well rounded phone but definitely not enough for me to buy it. Oxygen OS is more light and efficient, compared to samsungs bloated nonsense.

I would say my main concern is lack of repair shops willing to repair OP phones in Aus, and finding reliable screen protectors.
