Sony Xperia 1

The Sony Xperia 1 is an Android smartphone made by Sony. Part of Sony's flagship Xperia series, the device was announced to the public at a press conference held at the annual 2019 Mobile World Congress event on February 25, 2019. It’s the world's first smartphone with an ultrawide 21:9 aspect ratio 4K HDR OLED display, dubbed Cinema Wide, and Sony's first triple-lens camera system featuring Eye AF eye-tracking technology seen in the company's Alpha line of professional-grade cameras. The Xperia 1 was later joined by a more compact device, the Xperia 5, which was revealed on 5 September 2019. Compared to the Xperia 1, the Xperia 5 has a smaller 1080p screen, a smaller battery, and a non-centrally aligned camera module.

On 25 October 2019, a upgraded version of the Sony Xperia 1 called the Sony Xperia 1 Professional Edition (J9150) was released exclusively in Japan, which is mainly sold SIM-unlocked and unlike the Japan-only carrier models, features a hybrid dual-SIM slot and has an internal storage capacity of 128 GB like the J8110, J8170 and J9110 models. The J9150 model, however, does not include support for the 1seg mobile TV, nor does it include support for the Mobile Feli Ca or the Osaifu-Keitai, unlike said carrier-only models.
