Ice Universe: Samsung's Privacy Display beats Huawei and Xiaomi, but costs brightness

Leaker Ice Universe says Samsung leads in Privacy Display tech with four-way baffles blocking views from the top, bottom and sides, while Huawei and Xiaomi only block horizontal angles. The aggressive implementation on the Galaxy S26 Ultra causes noticeable off-axis brightness loss, reduced clarity and, for some users, eye strain and nausea. Xiaomi's 18 Pro series counters with software features like voice activation, location triggers and shoulder-surfer detection.
