Samsung Galaxy S20 Ultra review

The Samsung Galaxy S20 Ultra goes big in every way imaginable, with 108MP photos, a 100x camera zoom, 40MP selfies, and a 6.9-inch 120Hz display. With over-the-top internal specs on a par with some laptops, you'll pay more for this phone than any non-foldable phone before it, but that's not surprising. What is surprising are some of the bugs we've encountered that keep the Ultra from reaching its full potential.

Samsung Galaxy Z Fold 2:The most futuristic phone of 2020

The Samsung Galaxy Z Fold 2 is the only foldable phone you should consider buying in 2020 if you want to maximize that satisfying ‘wow’ factor when showing it off. It feels like you own a smartphone from the future when you collapse its tablet-sized screen in half, and the larger front display and stronger hinge fix the biggest Gen 1 issues. Be warned: it’s still priced for early adopters and the cameras on the Note 20 Ultra are better.

Samsung Galaxy S20 Ultra

The Samsung Galaxy S20 Ultra is a true groundbreaker that defines what we'll be doing with our phones, and with 5G, for the next few years. But after looking at all three Samsung Galaxy S20 models, I've decided the Ultra is just too much. It's too expensive, it's too heavy, and its vaunted "100x" camera takes up to four seconds to lock in focus. It's my third choice in the S20 lineup after the all-around champ that is Galaxy S20+ and the friendly, portable Galaxy S20.
