The BlackBerry A10 smartphone's specs have apparently been leaked online, Digital Spy said.

What appears to be a confidential document from the Canadian firm containing information about the new flagship handset surfaced over on the CrackBerry forums.

The A10 is said to feature a 5-inch OLED display with 1280 x 720 resolution, and house a 1.7GHz dual-core processor, quad-core GPU and 2GB of RAM under the hood.

Other listed specs include an 8-megapixel camera on the rear, a 2-megapixel shooter on the front, 16GB of on-board storage, and support for microSD, micro USB, HDMI, NFC and 4G connectivity.

The handset also appears to feature a 2800mAh battery, and will come running the next version of the BlackBerry 10 operating system - BB10.2.

BlackBerry is yet to officially announce the A10 smartphone, but previous reports have tipped it for a November debut.
