EDITORIAL: Unlike X200 Ultra, the X300 Ultra is sold outside of China. Vivo is delivering it's finest camera-phone by putting a double 200MP sensor camera (industry first) and offering not one but two optional tele lenses (a 200mm and a 400mm). Lens coating is still by Zeiss but like with other current Vivo's phones: all other camera tech (hardware and software) is home grown.

EDITORIAL: The S25 Ultra may be an incremental upgrade in hardware and camera tech but it is a world leader in AI functionality as Samsung turns to AI software to set itself apart from the competition. This is a phone with top performance, a full day of battery life, excellent photo and video results and 7 years of very stable OS package. Included is DeX - still the very best desktop replacement software there is. The screen, while not the brightest minimizes reflections and is more usable outdoors than any other. This year, Samsung decided to give us an Ultra with improved battery endurance and faster charging too. The lack of expandable memory is the only thing keeping the S25 Ultra back. The included stylus lost its Bluetooth but still works great.
PROs
Snapdragon 8 Elite, >1400nits ~500ppi LTPO AMOLED screen with HDR10+ and anti reflective coating, excellent 200MP main camera joined by 10MP and 50MP telephoto lenses and a 50MP ultrawide, tried and true 12MP PDAF Selfie, 7 years of OS updates and AI features ahead of the pack, amazing DeX computer replacement software
CONs
218gr 77.6mm wide glass and metal brick with a small 5000mAh battery, >60min slow 45W (15W wireless) charging, Samsung's refusal to include expandable SDmemory storage (do you know how big are these 8k video files?), the ecosystem that's trying to lock you in since 2019
