Sadly, by all accounts, HTC won't be unveiling the One M10 flagship at MWC 2016, but the Taiwanese manufacturer might still show up at the venue and bring some announcements. A fresh leak, courtesy of Evan Blass, showcases an unknown device, allegedly dubbed the HTC A16.
Sadly, not much else is known about the device, but simply going by the model number, we can assume that it won't be a flagship offer, but rather more of a Desire-style one. This goes for design aspects as well - a plastic body, beefy main camera and BoomSound speakers. The latter seem to have undergone some modifications, at least on a cosmetic level, as the grill is now more compact. A16 could also be a working title and the device could easily end up in the Desire family.
The only other thing worth noting from the renders, is the pair of odd holes, within a circular module on the back of the phone. These could be for a case or accessory, perhaps even some sort of charging, we can't say for sure.
