There’s no guarantee that the User Agent Profile file sourced below is actually for the HTC M8, but we’ll have to take @evleaks’ word for it; in his most recent tweet he shot out the link to the file and apparently, judging by both his tweet and the URL structure, this phone will be on its way to AT&T. As usual with UAProf files, they’re not really telling: what we can make out of this is that we’re looking at an HTC phone with Full HD resolution — with a probably larger screen — that will be running Android 4.4 KitKat, and which will be arriving to AT&T.
The HTC M8 has been rumored to be the successor of the HTC One from 2013. Whether it will be a major update, that would warrant an HTC “Two” (or “One Two”) name, or an HTC “One+” moniker is yet unknown. What we do know is that more and more cases that got leaked recently seem to imply some sort of dual-camera employment on the back of the device. That, and then there’s also that 3D model which we’ve recently seen; however, we wouldn’t hold our breath for the validity of either of these last mentioned reports.
