It has a grippy polymer composite back welded to an aluminum core. (The edges are aluminum too.) It feels tough. The front screen is protected by Corning's Gorilla Glass Victus, the strongest glass you'll find on any Android phone, and it's IP68 water- and dust-resistant, so it'll survive being submerged in up to 1 meter of water for 30 minutes.
On paper, this is some impressive protection for the money. But just because the XR20 is using Gorilla Glass Victus doesn't mean this screen won't shatter. Pricier flagship phones also use the same material and crack when dropped. Thankfully, the lack of glass on the back of the phone means there's one less area you need to worry about.
It's not too often a manufacturer advertises dropping a phone. But on the XR20's product page, HMD says you can “drop it, get it wet, and even record your kid’s football game in the roughest weather.” So I dropped it. Three times, to be exact, on a sidewalk, from around 6 feet up. The screen … drum roll … didn't crack. There are a few minor scuffs on the polymer casing, but the display is pristine. Obviously, this is no guarantee it'll withstand your first drop, but the results are promising.
Other uncommon features include a spot to attach a lanyard on the bottom of the phone, in case you want to hang the XR20 from your wrist or neck, and dual SIM support (it's a hybrid SIM tray, so the MicroSD slot doubles as a secondary SIM slot). Along with the power and volume buttons, there are two additional ones on the left and top edges. The first activates Google Assistant, but the second is configurable.
I set it to turn on the flashlight with a single press, and to launch an app with a long press. I've noticed that I use the flashlight more at night now that it's much faster to access, and I routinely use the Google Assistant button to turn on my living room air conditioner before I get home.
All of this is made better with the inclusion of almost every smartphone feature you'd want. Headphone jack? Check. Expandable storage? Yep. There's also NFC so you can use it to make contactless payments at the grocery store. But my favorite? Wireless charging! It's pretty rare to see on a mid-range phone; the TCL 20 Pro 5G is one of the few others with this feature. I have wireless chargers all over my house, so I'll take plopping down a phone on a stand over fussing with a cable any day.
HMD promises three Android OS upgrades and four years of monthly security updates. That's the best software support you'll find on any Android phone—on par with Google and Samsung—though I should note that the company is slow to issue updates. The software experience is fairly clean and slick. There are a few preloaded apps, like Amazon and ExpressVPN, but you can uninstall them.
