Now we have to admit that in terms of design, the LG-made Nexus is certainly a departure from what we’ve been used to seeing from LG based on their previous models, but in a way that’s a good thing since a shake up in design might be a nice refresher. The rear shell also shows three cutouts.
One of which is presumably for the flash unit for the camera, another is probably for the camera itself, and the third cutout is a bit of a mystery. There are possible explanations for this, such as it could be a cutout for LG’s logo which is a boring but possible answer. Another is that it could be used as a fingerprint sensor that would take advantage of Android M’s native fingerprint system.
Another possibility is that it could be a secondary lens that would facilitate the rumored 3D camera that is said to be a feature of the phone. In any case all of this is assuming the component is the real deal to begin with, so be sure to take it with a grain of salt for now, but hopefully we will have more details about the rumored handset in the near future.
