HTC teased the "HTC One" just a few days ahead of its launch through the UEFA Champions League sponsorship two years ago, and it has done the same for its upcoming flagship smartphone, the HTC One (M9), confirming its launch.

The hoardings at the Champions League game reads: "The new HTC One, coming March 1" give a clear message that it is ready for a glamorous launch of the HTC One (M9), according to a report by Tech Radar.

The HTC One (M9) is scheduled for unveiling at the upcoming Mobile World Congress 2015 (MWC 2015) which will kick off on 2 March in Barcelona.
