New images of an alleged Galaxy S6 have leaked out today, detailing an AT&T prototype model featuring a glass back and front with metal sides.

[custom:mwc15]The pictures were originally leaked by a user over on the XDA-Developers forum, and show off a device covered in bubble wrap. Besides the previously mentioned glass back and metal sides, we also get a look at a large, rounded home button. Additionally, there appears to be a heart-rate sensor on the back, which would line up with images from case-maker Verus from earlier this month.

Overall, there isn't much that's surprising here. Samsung released a video teaser earlier this week that contained the line "metals will flow," so we already knew that the device would incorporate metal somewhere. Perhaps the most interesting bit is the inclusion of a glass back, which seems to point towards a more premium-feeling device. No matter the case, keep it locked to Android Central where we'll be bringing you everything there is to know about the Galaxy S6 on March 1 from Mobile World Congress in Barcelona.
