Xiaomi made the announcement on its Weibo account, which was located by the Android Authority. The company says that its new 12S Ultra will use Sony’s largest mobile phone sensor currently offered, resulting in better low light performance, faster focus and better dynamic range than expected from the small format of smartphones. This is not the first smartphone to use a 1-inch sensor. Last year, Sony announced the Xperia Pro-I, which was the first smartphone to feature a 1-inch sensor with phase detection. But in this case, the phone does not actually use the full size of the sensor and is instead a central cut. Although this results in better quality, as the sensor is larger, it was very difficult to say that it used a 1-inch sensor, while it really could not take advantage of it due to the physical limitations faced by Sony. the subtlety of a smartphone, the size of the sensor and the visuals. But Xiaomi Lei Jun says that the 1-inch sensor that comes with the 12S Ultra is very important, it will not be cut. How the company plans to deal with physical issues encountered by Sony on its phone is not clear. Jun also says that Xiaomi did not just buy the sensor, but that it was jointly developed between the two companies with a total investment cost of $ 15 million shared equally between them. The fruits of this development will first come to the 12S Ultra before it is available to other smartphone makers, so it is not exclusively Xiaomi forever. It is worth noting that only the 12S Ultra will have a 1-inch sensor while the 12S and 12S Pro will have the Sony IMX707. This means that the Xiaomi 12S Ultra is being developed jointly with Leica and Sony in some capacity. The German camera maker struck a deal with Chinese smartphone company in May and promised a long-term strategic partnership. Aside from the promise of an inch sensor, the only other details of the Xiaomi 12S series are that it will use the Qualcomm Snapdragon 8 Gen 1 processor.
