Today I noticed that my phone has a crack that goes across the bottom and crosses the mic hole. No drops no cuts. I taken care of this phone and this is what I get. The cut even goes and crosses the silver band. It's awkward. I wonder if tmobile will trade it for a newer one. Makes no sense. The note 3 or iPhone lasted longer without any types of normal wear cracks.Attachment 2914275
Just noticed as well today mine has THE same crack through the mic on bottom of phone and also on top of phone through infrared sensor. It's a known and not isolated problem among many G3 owners across the globe. Google it.
