Reviews for the ZTE Nubia Z20
Source: Neowin

The nubia Z20 is easily my favorite phone among the ones I've used. The dual-screen implementation is thoughtful, and nubia found multiple ways to make good use of it. The pressure-sensitive edges are a feature I didn't expect to see and it's proven to be pretty useful for me. Meanwhile, the camera is easily the best one I've used, with a pretty great night mode to go along with it.

The ZTE Nubia Z20 is a great phone. Take away the secondary screen, and it's still a great phone. The camera is solid, it's blazing fast, and there are no obvious compromises. On that basis alone, I'd recommend it.

The Z20 feels forced, like Nubia tried too hard to make it special just for the sake of it. The second screen is a nice conversation opener, but that’s about it. Meanwhile, you can get similar specs and a hassle-free camera experience from many competitors, without spending more. For these reasons, we can’t recommend picking up the Nubia Z20, unless you really like the idea of having a second screen on the back of your phone.

The nubia Z20 has one thing that the rest don't and that's the novelty dual-display design. If you came here because you like exotic phones with quirky features, you will like the Z20 a lot. But if you don't have a particular use case for that secondary screen, you should know that the novelty wears off quite quickly and you will probably get bored with it pretty fast.

A dual-screen phone won’t be for everyone, but the Z20 is the closest you’re likely to get to a second display with mass-market appeal. A variety of settings and options mean you can use the second display as little or often as you like, while still enjoying all the benefits of the main camera for selfies, but it still feels a little awkward even at the best of times. It’s just a shame that camera isn’t better, with strong hardware let down by software that’s only OK. Then again, factor in the price - and super specs - and the Z20 delivers plenty of bang for its buck.

For the Nubia Z20, in addition to the Qualcomm Snapdragon 855 Plus platform, in terms of performance, the photo is also closely followed by the trend to join the 48 Megapixel and three-photo configuration, in the final performance It is also remarkable. I think the biggest improvement of this phone is the continuation of the ultimate pursuit of mobile video in the Nubia Z series. In the past few years, the entire mobile phone market has spent more and more energy on taking pictures. As the masterpiece of Nubia, the Z20 is just the beginning.
