LG G3 caught in the wild, back-mounted keys here to stay

We’ve been getting hints about it for a while now, but this is the first time we get to actually see what will certainly be one of the hottest smartphones of the summer. We got a photo of the LG G3's back and while it’s not the best quality it tells quite a lot about the device.
The design aligns nicely with those cases that leaked earlier this week and we can clearly see that the innovative back-mounted keys are here to stay. The actual keys have been redesigned, though compared to what the G2 lineup had.
We can also confirm that there is some sort of sensor next to the camera of the LG G3. Earlier we speculated that it’s either a sensor or a second LED flash, but here you can see that it looks nothing like a flash. We are yet to see what kind of sensor that is, though.
The notes behind the LG G3 pictured mention OIS+ as well as 16 and 32GB storage versions. We assume the 2GB and 3GB refer to the on-board RAM, but it’s unclear if LG is currently deciding between the two or if we’ll get two different versions of the smartphone.
