EDITORIAL: Like other Cheese phone makers, Vivo is going small. This years X vanilla model is 2mm narrower and almost 10mm shorter to put X300 well into the new "compact size" of 72mm or less. The battery is bigger than before and the Zeiss branded camera system Vivos are known for is also upgraded. It now features a new 200MP main and a new 50MP AF selfie. The built is improved as well with silky finish both on the back glass panel and on a (squarish, iPhone-like) aluminium frame.
