HTC One Mini confirmed in official UA Prof file
The HTC One Mini, also known under its HTC M4 codename, first appeared in images on Phone Arena, shown along with the larger 4.7-inch HTC One.
The UA Prof file does not confirm any specifications except for the screen resolution, but all rumors agree that the One Mini will have a 4.3” 720p display and be made of the same unibody aluminum like the One flagship. Moreover, it is also sporting two front facing speakers and it’s possible that it’d get an UltraPixel camera.
It is not the same high-end affair as the HTC One, though. The One Mini edition is said to feature a dual-core processor (likely a 1.4GHz Snapdragon 400) with 2GB of RAM, 16GB of internal storage and a 1700mAh non-removable battery.
The device should get unveiled fairly soon - around the end of Q2 - and run on the latest Android 4.2 Jelly Bean with HTC's Sense UI on top.
