Made with special materials, Fujitsu shows how the screen is unbreakable, unscratchable, the special casing makes it the worlds thinnest smartphone at only 6.7mm. Sorry about the bad sound quality, my microphone was nearly out of battery (I bought a new Sennheiser MKE400 for 199 Euro at Media Markt just in case my previous same microphone is somehow broken now after 3 years of use).
