I've been looking at all available pictures from the device so far and there's a couple interesting things to see.
At least at some point, the USB C port apparently was (or still is) on the long side of the phone, together with the 3,5mm jack.
The phone also sports two cut outs for camera related things, so I'd guess we get a single lens camera plus some AF module (flash window is also visible)
It also appears to be fairly thick, getting my hopes up for a large enough battery.
