After months of gestation, vivo X1 was finally officially released on November 20. The 6.55mm fuselage record has once again set a new minimum standard for the thickness of smart phones, and the Hi Fi sound effect has also become the distinctive focus of X1. In the current era when domestic smart phones tend to flood, vivo X1, with its professional music features, has strongly entered the consumers' vision. How does this machine perform? Take a look at the detailed evaluation of this product. Appearance: 6.55mm ultra-thin thickness The overall style of vivo X1 is simple and fashionable, and the large screen can bring good visual effects. The machine adopts independent virtual keys, and the return key is placed on the right side to prevent accidental touch operation. X1 is equipped with a silver white frame, which looks fashionable and full of texture on the whole, but the author cannot confirm what kind of material it is. There are keys on the frame, which can be confirmed to be made of metal, similar to the side keys of the iPad mini.

6.55mm body thickness is definitely a feature of X1, and there is no protruding camera design or any redundant attachment under this thickness. Thanks to the ultra-thin body, X1 feels very good when it is held in the hand. The 145g body weight sets off the texture of the whole machine, without any frivolous feeling. In terms of thickness, we use OPPO Finder to compare with this vivo X1.
