HTC ONE (M9):-

The HTC One M9 is an Android smartphone manufactured and marketed by HTC. The third-generation One was officially unveiled in a press conference at Mobile World Congress on March 1, 2015 and it was released to wide retail availability on April 10, 2015. It is the successor to HTC One (M8).

Hardware

The design of the M9 is similar to its predecessor, except that it is slightly narrower and thicker.The device has proper IPX3-level protection against spraying water. Available separately is the HTC Active Pro Case, which offers IP68-level water and dust protection, and a shockproof rating for up to a two-meter drop.
The phone features an octa-core Qualcomm Snapdragon 810 system-on-chip with 3 GB of RAM, a 5-inch 1080p display, and 32 GB of internal storage (nearly 9 GB is reserved for the operating system). Storage can be expanded with a Micro SD card up to 2 TBs.
The UltraPixel image sensor (which had larger pixels in its sensor, but sacrificed megapixel size for enhanced low-light capabilities) was moved to the front-facing camera, with the rear-facing camera now using a more traditional 20 megapixel sensor, supporting 4K video recording. The M8's depth sensor was also dropped.
The M9's front-facing "BoomSound" stereo speakers now use Dolby Audio tuning.
The built-in infrared (IR) sensor can make the device a remote control for other infrared-enabled gadgets.

Software

The M9 runs Android 5.0 Lollipop with HTC's Sense 7 user interface and software suite. HTC intends to update the M9 to Android Marshmallow

following its release.
