As you can see below, these LG G5 protective cases suggest that the device has a fingerprint scanner on the back, just below the rear camera, while its volume buttons are situated on the left side. That's certainly in line with what was previously said about the smartphone. The leaked images also show the front of the device, though there's no way of telling if that's what the real product will look like, of if this is just a placeholder.
These case seem to be ready to ship on February 28 via Amazon. LG is seemingly planning to announce the G5 on February 21 at MWC 2016, so it could start selling it on February 28. The new smartphone should be made out of metal, unlike its predecessors (G4, G3, etc). Of course, for now, we can't be certain of anything. But we'll be here to let you know all about the LG G5 as soon as official details arrive.
