As we remember, Sony decided to change names to their devices. In the end we lost the line of "Z", but got the memory "X". Xperia X, Xperia X Perfomance, Xperia XA, and now GFXBench managed to fix a new smartphone whose name is still unknown. While I propose to call it 24UJ95LH34QX77B1.
According to the specs the device is similar to the already mentioned Sony Xperia X Perfomance. It uses Qualcomm 820, also got 3 GB of RAM. The screen resolution is 1920x1080 pixels, but the diagonal of 5.1-inch, which is slightly more than the Perfomance. However, an error of 0.1-inch allow.
But there are some other minor differences between the two gadgets. For example, cameras here on the 21st and 12 megapixels, but not on 23 and 13, like the Perfomance.
While it is difficult to say whether Sony is preparing a brand new model, and this is only a early sample or in the company felt the need to produce a lightweight version of the Xperia X Perfomance, maybe even focus on some specific region only.
