As expected, the Taiwanese tech manufacturer unveiled its latest flagship smartphone, the HTC One M9, on Sunday at the "Utopia in Progress" press event of HTC Corporation in Barcelona, Spain. The launch event was organized a day before the opening of the three-day Mobile World Congress (MWC) 2015 trade show, which opens on Monday.

Launching the latest flagship device, HTC CEO Peter Chou remarked that the third generation device of the company is a blend of the antenna technology of the manufacturer's previous model HTC One M7 with the seamless unibody design of the immediately past flagship model HTC One M8. The antenna technology enables the One M9 smartphone to have a more or less entirely metal body.

IB Times lists the specs and features of the latest HTC flagship smartphone as below:

•  Dual-tone hairline and mirror finish
•  Qualcomm Snapdragon 810 chip
•  BoomSound speakers with 5.1 surround sound developed by Dolbly
•  Custom themes
•  Sense 7 user interface
•  Home widget
•  20-megapixel rear camera, UltraPixel front camera

The HTC One M9 is available in different color options, silver, gun-metal gray, pink, and gold.

According to the Taiwanese tech firm, the HTC One M9 will be available to the consumers in several markets in mid-March. HTC gadget fans in the U.S. and Asia-Pacific region can expect to purchase the smartphone at the same time.

Apart from unveiling the latest smartphone, HTC also took advantage of the press meet to announce the HTC Grip fitness tracker, which has been developed in collaboration with the sportswear company Under Armour Inc. The company also announced the HTC Re Vive virtual-reality headset developed together with the gaming firm Valve.
