If you thought HTC's One M9 was just too small or too bulky, you'll be glad to hear that the company has something bigger in store... yes, literally. Chinese regulators recently spoiled the surprise for the One E9, a 5.5-inch cousin to the 5-inch M9 that ditches the curved metal back for a flatter (and somewhat Desire Eye-like) body. This isn't just a re-skin à la the One E8, folks. There may be big changes under the hood, too. Well-known tipster Upleaks claims that the E9 will switch from a Snapdragon 810 processor to a 64-bit octa-core MediaTek chip, and that you'll get a super-sharp Quad HD screen instead of the M9's 1080p display. A "standard" version could also ship with a regular 13-megapixel front camera, while a "high" version would carry the M9's low light friendly 4MP UltraPixel cam.
