Over the years Sony’s brand has be defined by quality, both in build and user experience. This lends itself to essentially every industry Sony gets itself into, from gaming to mobile and everything inbetween. Since the launch of the Xperia Z series and the rebranding that the Xperia lineup went through in the process, Sony’s Xperia lineup of phones has featured a glass back in addition to the traditional glass face of smartphones. While this makes the device very pretty it also presents a problem: hit it too hard or just right and that glass is going to break.
We’ve seen this problem with anything else made from glass, whether it be a car windshield getting hit by a pebble and shatterinig or something else just as seemingly ridiculous, glass isn’t exactly the best material for resiliency. The original Xperia Z was thus known for getting its glass cracked easily, and over the years Sony has improved the build quality of each and every Xperia handset up to the most recent Xperia Z3, which features more rounded edges made of material that’s supposed to accept crashes a little better than the previous generation. Unfortunately some users are now reporting that there may be a defect in Sony’s design, as claims are being made that screens are cracking for no good reason.
