The smartphone is not only dust and waterproof according to IP68 but also offers an IP69K certification, allowing it to withstand a water stream with a pressure of 100 bars. The Nokia XR21 leaves a high-quality and particularly robust impression, presenting itself with clean workmanship. The back is made of shock resistant polycarbonate, and the front is protected by Corning Gorilla Glass Victus. HMD Global calls them dampening TPU shocks. The rubberized smartphone corners aren't very visible, but you can still feel them.

However, the design still looks a bit aged, with the rather mediocre display-to-surface ratio of 77% also contributing to this impression.

At a thickness of 10.45 mm (~0.41 in), it definitely is not a slim smartphone, but it is still slimmer than a classic rugged phone such as the CAT S75 and especially also noticeably lighter. The Nokia XR21 is available in the colors Midnight Black and Pine Green.
