LG G3 owners complain about cracks through the microphone opening

A problem with the build quality of the LG G3 is beginning to show up globally. Cracks are appearing by the microphone opening, from the top to the bottom. Some T-Mobile customers with the phone are making
the same complaints, adding that there are difficulties inserting a jack into the microUSB port. Some feel that by trying to force a microUSB jack into the port, the cracks are being formed in the plastic casing.

In Hong Kong, an entire forum thread has been devoted to the problem. So far, there has been no word from LG about the matter. Pictures from LG G3 owners with this issue, all show the same problem, with the same thin crack running through the microphone opening.

If you own the LG G3, has this crack appeared on your unit? Did you attempt to return the phone for a non-damaged model? As news of this flaw starts to spread, LG is going to have to come up with a way to save face, and to also make sure that those with a cracked handset receive a new unit.
