The verdict, up front

The all-screen flagship answer.

Z70S Ultra is the only 2025 flagship shipping a true edge-to-edge display thanks to its fourth-gen under-display selfie — undercutting Xiaomi 15 Ultra on price and matching it on chip. The trade-off is a softer selfie photo and an under-developed software skin (Nebula AIOS).
