The HTC One Mini 2 smartphone has been approved for sale in Asia, Digital Spy said.

Although the manufacturer is yet to announce the downsized handset, Taiwan's National Communications Commission (NCC) has confirmed its existence.

The NCC listing does not confirm any specs details for the Android device, aside from the fact that it supports 4G connectivity on the 700 MHz, 900 MHz and 1800 MHz frequencies, Focus Taiwan reports.

Reports suggest that the HTC One Mini 2 will feature a 4.5 inch 720p display, a quad-core Snapdragon 400 processor, 1GB of RAM, 16GB of storage and a 13-megapixel camera.

Leaked photos of the phone suggest that the dual-lens Duo camera of the HTC One M8 has been omitted, while the flagship's aluminium design has been retained.

HTC is expected to announce the device later this month.
