Samsung is still offering a default resolution of Full HD+ (2220 x 1080), which looks more than sharp enough for most tasks, and saves battery; you’ll need to head into the settings to switch to the higher resolution.

The physical 3x zoom lens, meanwhile, is a distinct improvement over last year's 2x; unlike the 3x on the OnePlus 7T versus the 2x on the OnePlus 7 Pro, it's just as sharp, and it's more zoom. At 4x, you can definitely tell the difference between this and a 2x-based phone like the Samsung Galaxy Note 10+.

The screen is a 6.7-inch, 3,120-by-1,440 AMOLED panel. The screens on the three new S20 models are all the same resolution, which means they get denser and even better to look at as the sizes go down. They're 14 percent brighter than last year's displays, according to DisplayMate Labs, and you can definitely see the difference between this and a Galaxy S10e. We know an increase in screen size might be off-putting for some (there’s pent-up demand for smaller one-hand-friendly phones), and we have good news and bad news about that. First the good news: while the S20 is taller than the S10, it’s also a little narrower, with a 20:9 aspect ratio, and the screen is only marginally bigger. a b "Samsung Introduces Next Generation of Tactical Mobility with the Galaxy S20 Tactical Edition".

There are five Galaxy S20 colors in total, but not all of these are available in every market. The options are Cloud Blue (the handset pictured most in this review), Cosmic Gray, Cloud Pink, Cloud White and Aura Red. SamMobile (4 June 2020).

On our Wi-Fi video rundown test with the screen set to full brightness, I got 11 hours, 11 minutes in HD 120Hz mode, and 13 hours, 13 minutes in WQHD 60Hz mode. That's about one hour more of screen-on time in 120Hz mode than with the S20, and two hours more in 60Hz mode. There's a similar difference between the S20+ and the S20 Ultra, with the Ultra's battery life being longer. Low-light performance is as good as the Ultra, and sometimes better. It's also considerably better than the Galaxy S10. Some of the difference, I suspect, is in software, as the Ultra tends to over-brighten some night scenes. There is an especially noticeable difference in low-light photos taken with the front-facing cameras. The Galaxy S20 runs Android 10 as standard, with an upgrade to Android 11 now possible. Samsung’s own One UI is overlaid, so it’ll look different to the software you may have used on other Android phones that aren’t made by Samsung, but the design is attractive and it’s easy to use.
