Rumors began appearing earlier this month that HTC was developing a new flagship smartphone codenamed the M7, and the always-prolific @evleaks has followed-up with its own details. As reported on Unwired View, the M7 is said to improve upon HTC's current flagship Android phone, the One X, nearly across the board: with a 4.7-inch HD display at 468ppi (reportedly called a SoLux display), a 1.7GHz Snapdragon quad-core processor, 2GB of RAM, 32GB of storage, and LTE and HSDPA radios. The M7 will also reportedly carry an improved camera with a 13-megapixel sensor and an f/2.0 lens. Evleaks says that the M7 should be headed to Verizon and Sprint, and that there's a possibility it could be HTC's first smartphone since the Touch Pro 2 to be offered on the four largest US carriers. We'll find out soon enough — that is, if the phone is revealed at Mobile World Congress as rumored.
