Based on the leaked case, the fingerprint scanner will be on the back, above the camera, and users will have to swipe their finger across the glass on the back. That is similar to the scanner on the HTC One max, and quite different than the TouchID scanner used by Apple for the Apple iPhone 5s. The scanner on the iPhone is embedded in its home button and requires the user to keep his finger still for a brief period of time while the sensor reads the fingerprint. HTC One max users claim that having the fingerprint scanner on the back makes using it rather difficult.
The latest rumored specs for the M8, which is expected to be named the HTC One+, includes a 5 inch screen with a 1080 x 1920 resolution, and a quad-core 2.3GHz Qualcomm Snapdragon 800 CPU under the hood. We expect to see 2GB of RAM on board, 16GB of native storage inside and a microSD slot for those needing additional storage. A 2900mAh cell keeps the lights on. Android 4.4 is pre-installed out of the box.
The HTC One+ is expected to be launched in March after being unveiled at next month's MWC in Barcelona.
