First off, I grabbed some photos with the stunning PRO 7. The beautiful models definitely brought an aura of elegance. 
Particularly when the models showcased the PRO 7's secondary display, it felt quite unique. 
On the other side, another model was holding the recently popular red variant, looking even more striking. 
Who says magic beans can't be masculine? A man holding the PRO 7 looked equally stylish. In fact, I think the secondary display is more suited for professionals, as it allows for better performance during meetings and ensures no important updates are missed. 
It’s no surprise that the ladies love selfies. From the way this girl is holding the PRO 7, it’s clear she’s into it. This picture is really something special—seeing this scene on the street would probably cause quite a stir. 
Is this a more “standard†selfie pose to flaunt the PRO 7? The magic beans also quickly got their hands on the PRO 7, and it seems they’re already enjoying the benefits of the secondary display. Whether it’s for taking pictures or checking notifications, the PRO 7 has clearly piqued their interest. 
Hey, my friend’s selfie game is on point! 
It’s always exciting to get your hands on a new device like the PRO 7. Both the 5.2-inch and 5.7-inch options are great. Which size do you prefer? The 5.2-inch version is the PRO 7, while the 5.7-inch is the PRO 7 Plus. 
Hey, the screen color of the PRO 7 is fantastic. That’s the charm of Samsung’s Super AMOLED screen—it’s beautiful and comfortable to look at no matter how you view it. 
The standout feature remains the secondary screen on the PRO 7. Not only does it display more information and features, but it also pairs well with the dual cameras for added interactive fun. It might take some getting used to, but after you get the hang of it, it’ll become second nature, like the “mBack†feature. Additionally, the Meizu logo is now placed differently, making it less uniform but increasing its recognizability. It has that classic MP3 design vibe to it. 
I quickly tried out the system—it felt incredibly smooth. This is based on Android 7.0 with Flyme6, which has earned a solid reputation for optimization. What further improvements will the PRO 7 bring? We’ll have to wait and see, but I’m excited to see how Flyme6 enhances the secondary screen experience. 
Do you prefer 5.2 inches or 5.7 inches? Personally, I lean toward the 5.2-inch model since it offers ideal one-handed operation. The single-handed swipe makes the controllable screen area more efficient. 
Quickly testing the secondary display, it can be clicked, double-clicked, or swiped—very similar to the main screen. But there are subtle features that require time to master. Early impressions are positive, though the call function’s new double-click feature still feels slightly awkward. 
Trying out the dual-camera setup again, the bokeh effect is impressive. The phone’s screen results rival those of an SLR. 
Black-and-white photography also impressed (due to on-site lighting issues, this black-and-white image turned out overly bright, but the camera did manage to capture color casts, apologies). 
Lastly, let’s talk about the Meizu PRO 7’s appearance, color, and style. Besides black, the other two colors are quite distinctive—one inspired by the classic red of Italian oil paintings, the other drawn from the metallic hues of the fashion world. These unique color choices are likely to attract many consumers, as they’re both eye-catching and complemented by the innovative triple-screen design, giving the PRO 7 a fresh and unique aesthetic. Which color do you prefer for the PRO 7? Meizu has consistently pushed boundaries with its innovations, and this secondary display is far from a gimmick—it’s a practical and dazzling new feature. Will it earn more praise? Only time will tell.
