A number of Surface Duo owners are taking to social media and online message boards to complain that their all-new device is developing cracks around its USB-C port. From preliminary chatter, it sounds like only the outer protective band, made out of rubber and plastic, is affected while the actual metal casing of the port is still intact.

It’s not immediately clear as to how widespread the issue is, but going by the number of complaints, it is unlikely to be a few isolated incidents. Either way, let’s see if (and when) Microsoft will officially acknowledge the problem and announce any remedial measures. In the meantime, users will do well to ensure that they take extra caution while using the USB-C port on the device.
