Vivo X20A spotted at GFXBench, confirms several specs

Just few days back, Vivo X20A made its way at Geekbench. Now, the cell phone has made its way at GFXBench, revealing most of its specs in full glory.
According to the listing, the handset packs in a 6-inch multi-touch display with 2160 x 1080 pixels resolution, making it an 18:9 aspect ratio. It has an octa-core Snapdragon 660 processor with maximum clock speed of 2.2GHz. It is paired with Adreno 512GPU for graphics.
The benchmark confirms that Vivo X20A comes with 4GB RAM and 64GB internal storage space (51GB user available). It should support 4G LTE and supports most connectivity options like Wi-Fi, Bluetooth and GPS.
The handset is equipped with 24MP selfie camera that can take 4K videos. The GFXBench listing reveals a single 24MP rear shooter with LED flash, Auto Focus, Touch Focus and 4K video recording.
The X20A was said to be similar to Vivo X20 which is allegedly believed to have 12MP + 12MP dual shooters at the back. The listing of X20A model does not reveal dual camera setup. I am still open to the idea of two cameras though and wait for an official word.
The Vivo X20 and X20A smartphones will go official on September 21, 2017, just couple of days from now. Official details, including pricing will be revealed there.
