HTC One Max phablet poses for a family portrait, flashes a fingerprint sensor

By now it's clear that HTC will make an entrance in the phablet arena by the end of the year with the so-called HTC One Max handset, adding a third screen size to its One portfolio.

The handset is expected to show some of that same aluminum unibody design prowess, wrapping a monster 5.9" Full HD display, Snapdragon 800, an UltraPixel camera, and, thankfully, HTC might have found a spot for a microSD slot, or so say the rumors.

What we didn't know so far is how exactly is HTC planning to differentiate its first phablet from the competition that is getting stronger in this area with phones like the Xperia Z Ultra, and the expected Note 3.

If a leaked picture of the One trio is to be believed, one of the new features is said to be a fingerprint sensor on the back. It can be used for authentication, mobile payment authorizations and so on, while Apple is heavily rumored to include one with the iPhone 5S, too. On the picture we can also see a dock connector or electrical contacts of sorts, so there might be plenty of surprises to look forward to with the One Max, other than the "first HTC phablet" factoid.
