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.

* TOP Photography
EDITORIAL: Ten months since last Xiaomi’s Ultra comes a phone with the first-ever physical zoom ring. 17 Ultra Leica edition features a physical zoom ring, ribbed frame for better grip, encryption chip and dual satellite communication chops that plain 17 Ultra lacks. Both models loose one of the two telephoto lenses 15 Ultra had and their screens drop below 500ppi. The phones gained in width and battery size but their photography skills are better then ever. SUPERPOWER: this is the TOP 5 photo phone in the world
