Rumor of a beefier HTC One M9 variant -- aka "M9+" -- had been floating around for some time, but we've remained skeptical until we came across the latest batch of leaks. Better yet, some of these are backed up by an official (poorly made but actually legit) Beijing launch invitation sent out earlier today; see for yourself after the break. What we're seeing is that the Duo Camera feature on the M8 is here to stay, and there's also the previously rumored front-side fingerprint reader which, sadly, reminds us of the home buttons on earlier Samsung devices.
Another leak shows that this "M9pt" device -- the "t" means this is for China Mobile -- packs a QHD (2,560 x 1,440) display, a MediaTek MT6795T 64-bit octa-core chipset (with PowerVR G6200 GPU), about 3GB of RAM and the same 20-megapixel camera as the M9 -- albeit in a prettier circular shape instead of a squircle.
Little else is known about this M9+, but given the April 8th launch event in China, it won't be long before we find out more. We must say, though, that HTC China really needs to hire better graphic designers.
