oleophobic coating issue?

[Nubwy]

Just noticed that my front facing camera and sensor strip on the top front of my phone as well as the area surrounding the speaker phone have no oleophobic coating. So when I take my phone from my ear, the rest of the phone is fairly clean while the top strip is grease central. What should I do? Not a deal breaker but I never had any problems like this from my iPhone lol. I can probably live with it. Just mildly annoying that something so simple is not QC'd.
