These guys advertise their so called S+ grade as *OEM*. They do have other grades that are "OEM-Compatible". Thus, S+ is definitely advertised as genuine products. Unfortunately, I received an S+ grade Samsung S4 glass-digitizer module that is *NOT* even properly assembled! As you can see from the attached photos, a working part would have the vertical flex cable on top of the horizontal one and connect to the white connector above. Their part has the vertical cable buried under the horizontal one and connects to nowhere! The touch function as a result is not working. I doubt this is an OEM product and likely a counterfeit!
