Exploring the rear display on the Xiaomi 17 Pro Max

The Xiaomi 17 Pro Max features a distinctive secondary display on the back of the device — a 2.9-inch panel embedded within the camera module, capable of showing widgets, notifications, camera previews, and even gaming controls when paired with a special case.
The question for UK buyers is: how useful is it in everyday life, or is it more of a gimmick?

Firstly, the functionality is real. The rear display lets you check the time, view incoming notifications (calls, messages, delivery updates) without flipping the phone. It also supports using the main camera lenses for selfies by turning the rear screen into a viewfinder — a useful trick for higher-quality self-portraits.
Those who take lots of photos of themselves, or switch between front and rear cam frequently, will appreciate this benefit.

On the flip side, the size and placement of the screen impose limitations. The panel is quite small (2.9 inches) and sits amongst camera lenses, which means the usable area is constrained. Some reviewers note that while it looks cool, its everyday utility is modest.
If you’re someone who simply glances at notifications on the main screen, the rear addition might rarely come into play.

Another use-case is for widget shortcuts or quick controls — for music playback, setting timers or accessing quick toggles without unlocking or turning the main display. This improves convenience marginally.
However, the availability of some features may depend on region or software version, so UK users might find function slightly restricted compared to adverts.

There’s also the gaming accessory angle: Xiaomi offers a “retro gaming” case that uses the rear display for a Game Boy-style experience. While clever and eye-catching, feedback suggests the actual ergonomics and practicality are weak — meaning this feature is more novelty than essential.
For UK consumers, unless you’re a niche gamer or tech enthusiast, this will likely stay unused.

From a design and lifestyle standpoint, the second screen adds flair and uniqueness to the phone. It sets the Pro Max apart in a crowded flagship market. If you like standout features and enjoy exploring them, the rear display provides that “wow” factor.
Yet if you prioritise practicality, one-hand usability, and minimal complexity, you may rarely tap into its full potential.

In conclusion: yes, the rear display on the Xiaomi 17 Pro Max can be useful — especially for camera self-viewfinder tasks, quick glance widgets and showing off something unusual. But for many UK users, it will be more of a fun bonus rather than a game-changing feature.
If you think you’ll use it frequently, it’s a nice perk. Otherwise, it shouldn’t be the deciding factor when choosing the device.
