Sony’s Xperia X series replaces the Xperia Z lineup. So far, the Japanese tech giant has introduced Xperia X, Xperia XA, Xperia X Performance and Xperia XA Ultra under the new lineup. However, now, a mystery Sony handset, tied to model number “24UJ95LH34QX77B1,” has apparently made a visit to the GFXBench site.

Looking at the leaked configurations, the upcoming Sony device sounds similar to the flagship Xperia X Performance. This new device will reportedly carry a 5.1-inch display and 1,920 x 1,080 pixels screen resolution. The Xperia X Performance, on the other hand, comes with a 5.0-inch display.

Under the hood, Qualcomm’s Snapdragon 820 chipset will power the new device with 3GB of RAM backing all the internal configurations. Adreno 530 GPU will take care of the graphics department. On the software front, Android 6.0.1 Marshmallow will run the device out of the box.

Furthermore, the upcoming smartphone will apparently sport a huge 21-megapixel rear-facing camera unit with LED flash, autofocus, HDR and 4K video support. In addition, there will also be a very-generous 12-megapixel front-facing shooter for selfies and video chats. The listing also says the selfie-clicker will be able to record 4K videos, similar to the main camera. In comparison, the Sony Xperia X Performance features a 23-megapixel sensor on the back and a 13-megapixel shooter at the front.

According to GSM Arena, this mystery Sony device could either be a new high-end smartphone or a region-specific variant of the flagship device Xperia X Performance.

Apart from the Xperia X series, Sony Xperia E series has been making news lately. The Xperia E5 is the next mid-range device with a pocket-friendly display, earmarked to be released on June 5.
