Best 4k Display Mobile Phones (Jan 2023)

It's rare to find smartphones that have 4K resolution screens. Only Sony has launched smartphones that have 4K resolution, and there are exactly three such phones in the world right now. In 2015, the Sony Xperia Z5 Premium became the world's first phone to feature a 4K screen panel, but its UI was still rendered at 1080p resolution, with only images and videos able to take the full advantage of its 4K screen. The Sony Xperia XZ Premium was launched in 2017, and it had a 4K LCD panel, too, and it was the world's first phone with a 4K HDR10 screen. Sony launched Xperia 1, which was the world's first mobile phone to be launched with a 4K 21:9 OLED HDR screen. Most people won't be able to distinguish between a Full HD 1080p and a 4K 2160p screen on a mobile phone, and 4K screens require a lot of processing power, but brands can always find ways to market their phones in a unique way.
