We are aware that some units of the first production batch of the transparent and black translucent slim cases are susceptible to breakage. This may happen when the phone and its case did not experience pressure or fall damage.
What happened?
The original hard coating process meant to provide additional protection against scratches has caused the material of some of the new transparent and black translucent production units to become less flexible and thus brittle.
