Because I’m obsessed with the Librem 5, I took a screen shot of the video and then used GIMP to count the pixels in the image. When I measured the 17x17 mm i.MX 8M Quad SoC (the pinkest square in the middle), I found a 5.6 inch screen and a case that is 70x142 mm. If the case is 14mm thick (as previously reported), then this is going to be a big phone.
However, I might be measuring the SoC wrong, since I’m trying to measure the chip package, not the box around it in the diagram. If we assume that the Librem 5 will have a 5.7 inch screen, then I get a slightly bigger case at 72x145 mm.
The picture confirms a few things for us. We will have a 3.5 mm audio jack in the upper right corner. There is an 8mm chin at the top above the screen where I see a speaker and 4 circles. I imagine that they are the selfie camera lens, a proximity sensor and an ambient light sensor. Maybe the fourth circle is a LED flash for the camera, a LED indicator light, or maybe just a microphone hole. The bottom of the phone is obscured, but there doesn’t seem to be a second speaker on the front of the phone. Maybe we will get a second bottom-firing speaker that we can’t see in the image, or maybe we only get one speaker.
The diagram shows three somethings on the upper right hand side of the case. I would expect those to be the Power, Volume Up and Volume Down buttons on a normal phone, but their shape looks like the three hardware kill switches. They are equidistant, whereas you would expect the Power button to be separated from the Volumn Up and Down buttons, so they are most likely the kill switches.
So where will the Power, Volume Up and Volume Down buttons go? On the lower part of the phone, where it is less convenient to reach them? Are you going to use the kill switches more than Volume Up and Down?
I guess that some people will be constantly flipping the switches on and off, but I don’t expect that I will use them that often, and I would rather have the Volume buttons in that convenient location. The security freaks, however, should be very happy with this design.
