1) The headline in red says Snapdragon, the details box says Exynos. Which does this S21 Ultra have? I'd be looking for Snapdragon. 2) Will this work with O2 and Three networks in UK? Thanks.

1, Sorry, some mistake in the details.  Correct processer : Qualcomm SM8350 Snapdragon 888 (5 nm)

2, Yes, it works
