It looks like Sony is getting into the business of bendable smartphones before Samsung or LG, but not intentionally. A bunch of users are reporting that the metal frame of the flagship Xperia Z1 handset has bent for no reason, leaving their phone in the state similar to the image here.
The culprit seems to be heat (from leaving it on the wireless charging dock to using it in the sun). It may be the result of sitting on the phone while in your back pocket, one too many times. That is more likely. We have no way to really know. It’s an interesting phenomenon to observe anyway, whether it is abuse of a fault.
Have you experienced something similar with your own Xperia Z1 unit? Let us know. We don’t yet know how widespread this is just yet. If we can believe it of course. It is probably just people abusing their phones. The metal and glass design is likely just showing stresses after some time by bending and getting tighter.
