The Butterfly 2 specs are based on One (M8) with some changes. It sports a 5" 1080p Super LCD3 display with the pixel density of 441 ppi. Powering the device is a Qualcomm Snapdragon 801 SoC with four 2.5 GHz CPUs. It has 2 GB of RAM and 16/32 GB internal storage with microSD card slot for further expansion.
The camera unit is a 13 MP f/2.0 sensor with depth sensor accompanied with 5 MP front-facing camera. Both cameras are capable for 1080p video recording. The BoomSound dual frontal stereo speakers come with a new amplifier, redesigned speaker chambers and a tailored audio profile for a truly high definition experience.
The Butterfly 2 is a waterproof and dust-proof device with IP57 certification. It is running on Android 4.4 KitKat with Sense 6 UI. You can now get it from HTC concept store for RM 2,299 and, sadly, JBL in-ear-headphones sold separately.
