This phone was released about the same time as the Samsung Galaxy Note 7 – which had battery explosions often.

3D visuals helps to understand connectivity and orientation of different parts, for example this image shows some sections highlighted:<\/p>\n

The following video shows the entire phone in 3D views of various internal sections, including inspection of electronics soldering pads – these always have some voids (air spaces) but they should not be too big, this one passes:<\/p>\n
