Sony Mobile has kept coy over exactly which glass is used in the Xperia Z. The only official word from the company is that the handset “uses durable tempered glass that has equivalent specs to Gorilla/Dragontrail.” It now appears that the handset might in fact be using both suppliers judging by a recent Hong Kong press conference.
One of the alleged slides from the presentation says that the handset uses Asahi Dragontrail glass for the front of the handset and Gorilla Glass on the back. We find it odd if this turns out to be true, after all why not use just one supplier for both front and back? The other interesting piece of information is that the handset is believed to use the NXP PN650 NFC chip which is compatible with both Felicia in Japan and Octopus in Hong Kong.
