Sony includes a shatter proof protector in pretty much all of its Xperia smartphones and has done so since the Xperia X10. What was interesting with the Xperia Z was that Sony baked the ‘Sony’ logo into the shatter proof sheet. This means that if you took that sheet off, you would lose the Sony branding on the front of the handset.
Well it looks like the same applies to the Xperia Z1. The bods at Recombu did a screen scratch test on one video and followed it up with another that showed how to take the sheet off. If you want a closer look, check out the videos below.
