Enjoy more screen-time with reading mode 2.0 with a TÜV Rheinland certified display that protects your eyes from harmful blue light We're impressed with the screen too, a 6.53-inch IPS LCD affair that runs at a resolution of 1080 x 2340 pixels and an unspecified refresh rate (none of that fancy 90Hz or 120Hz speed here, not at this price). It's bright and sharp, and perfectly good for watching YouTube videos or scrolling through the expanses of the web. It's one of the better displays we've seen on a phone down at this end of the price scale. We don't like the MIUI skin that Xiaomi puts on top of Android (Android 10 in this case) all that much, but your mileage may vary – it's just a bit too garish and interfering for our tastes, but there's nothing here that would necessarily put you right off the phone. You do get quite a lot of Xiaomi's own apps on board out of the box, but they're easy enough to uninstall or ignore if you don't like them.
