HTC One mini shares its design and many of its features with its bigger brother the One and sports a unibody aluminum body. That includes the HTC BoomSound technology, complete with dual frontal stereo speakers. It is is built around 4.3" display of 720p resolution resulting in a density of 341 pixels per inch. The screen itself is of the S-LCD2 variety and is protected from scratches by a Corning Gorilla Glass 3. Under the hood of this phone theres a Qualcomm Snapdragon 400 chipset with 1.4GHz dual-core Krait 300 CPU, Adreno 305 and 1GB of RAM. The internal memory is 16GB and sadly, there isnt a microSD card slot for expanding it. It runs Android 4.2.2 Jelly Bean with HTC Sense 5 UI icing on top. It gets treated to HTCs BlinkFeed and Beats Audio technology as well. At the back of this phone resides the same 4MP UltraPixel camera found on the HTC One. The only difference between them is the lack of optical image stabilization on the One mini. You still get HTCs ImageChip 2 and a BSI sensor of 1/3" size, though.
