Samsung's Galaxy S5 is rumoured to be touching down in February, and it could come with a diamond-coated metal body, if the latest murmurings are to be believed.
According to rumours, Samsung is experimenting with a "diamond metal surface treatment technology". This involves blasting carbon with high temperatures in the same way that's used to make diamonds.
This is to make it more hardwearing. "If the metal case is coated with a diamond material, vulnerabilities to scratches and deformation can be redressed," is how ETNews puts it.
ETNews also repeated the rumour we reported earlier this week, that Samsung plans to implement an iris scanner in the S5. This would let you unlock your handset just by looking at it.
Samsung is also reportedly experimenting with a 64-bit octa-core processor, a display with a pixel-per-inch count of 560ppi, and 3GB of RAM.
Chuck in an iris scanner and diamond-coated metal body, and you've got quite a phone.
But the S5 probably won't have all of these technologies, ETNews notes, as that would make the device too expensive.
Which it does come packing, we'll have to wait and see.
