Reportedly, the 4.5-inch screen of the M8 Mini will have a 720 x 1280 pixel resolution (this certainly makes sense). Other expected features: Android 4.4.2 KitKat, Sense 6.0 UI, quad-core Snapdragon 400 processor clocked at 1.4GHz, 5MP front-facing camera, 13MP rear camera, 1GB of RAM, 16GB of internal memory, and - hurray! - MicroSD card support. Like the larger M8, the Mini should come with on-screen buttons.
Since original One and One Mini handsets (pictured above) have a strikingly similar design, we’re assuming that the new M8 and M8 Mini will also look alike.
It’s said that HTC will announce the M8 (possibly called One 2 when it hits shelves) in late March. We don’t know if the M8 Mini will be unveiled at the same time. There should also be a dual SIM version of the M8, but, again, we don't know when this will be announced.
