First, let’s a talk a bit about the design. 

While the exterior of this phone is impressive, Xiaomi’s choice of components on the inside raises a few questions.

We start with the Qualcomm Snapdragon 665 processor, which also powers the sub-Rs.

Sony Xperia 5 smartphone was launched on 5th September 2019.

Vivo U3 smartphone was launched on 21st October 2019.

The 6.35-inch screen has an HD+ resolution of 720×1544 pixels, which is expected.

The Vivo Z1x sports a 6.38-inch full-HD+ (1,080 x 2,340 pixels) Super AMOLED display that the company claims covers 103 percent of the NTSC colour gamut and offers 430 nits of peak brightness.
