Let’s be honest, 2020 wasn’t a particularly good year for smartphone sales. We saw a handful of great phones hit the market, but the pandemic forced a lot of people to reevaluate what was truly important, and a flagship smartphone simply didn’t make the cut for most, especially devices like the...

I did not get to review the other S21 series, but based on the S20 experience, I think the S21 Ultra 5G would be a choice to go. My reason: the 100x space zoom is the killer feature that are not found in any other phones. Top that with S Pen support.

The Samsung Galaxy S21 Ultra 5G offers not only a 3x telephoto lens, but also a 10x telephoto lens. As long as you don't use the additional digital zoom, then results can be very good.

New 10x telephoto camera, Consistant results from all cameras, Excellent colour, Excellent range of cameras, Speedy performance and snappy responses
