Update: NVIDIA has reached out with a comment, and here is their take on the situation. “There have been reports of hairline cracks in the corners of the SHIELD tablet casing. The crack is cosmetic and does not affect performance. We believe this imperfection is caused by a material control issue during the production of a small number of tablets. This caused the material to become more brittle than expected. We will replace anyone’s unit that sees this imperfection. We’re still in investigation mode and will continue to provide updates as we learn more.”
Users on the official Shield forums have shared some of their experiences about cracks starting to appear after using the device, although there were even others who can be said to be more “unfortunate” as the cracks appeared right after the unboxing. Most of the cracks happen on the four corners of the device, although this does not mean that the cracks are exempt from making an appearance elsewhere around the frame.
There has been no official statement released concerning the reason for such cracks, and some have cited overheating to be the most likely culprit here. How about the perception that a cheap chassis was used instead?
