Wow, seems like metal chassis for phones are getting more attention. These are some spy shots of the Huawei P6-U06 Android phone that has metal casing. No details of the hardware specs.
Looks like it is from a single piece of metal. Here are some more shots. The person taking these shots should have focused it properly. BTW, it is just 6.18mm thin.
Seems like there are two colors: Black and Silver. Here is a shot of the black one.
