Disclaimer: my profession is automotive detailing. If you damage your phone, don't blame me.
After 3 days, my S7 edge had so many scratches and scuffs in the oleophobic coating, it was actually amazing to me. I thought technology has moved past these issues, Samsung?
There were 4 scratches so bad I couldn't handle it any more. I got some Meguiars 105 compound and removed the scratches. Result:
S**t. Now there's an oval on the screen that my finger doesn't glide over, plus that area captures every fingerprint and every bit of sweat from my fingertips.
I came across a product that was supposed to be a liquid screen protector made of quartz. The first thing that popped into my mind: CarPro Cquartz. Since I wouldn't want to use something that permanent and finicky on my phone, I decided to bust out some other CarPro products I had lying around the shop.

Eraser is essentially scented alcohol with other proprietary blends. 3-5 wipedowns with alcohol will give the same result. I used eraser because it was readily available.
Essence increases durability but is not the top layer, so results are equivalent with or without it; eraser hopefully will prolong applications.
Reload is 5% silicon dioxide. It is anti-static and weather-resistant. In this usage, it is nearly fingerprint-proof. Spray directly on the screen, wipe, and buff any remaining streaks.
Reload is expensive for a mobile device coating. However, you can also get incredible results on your car with this same product and I barely make a dent in the quantity of product when I use it.
It *will* have to be reapplied. OEM oleophobic coatings are more durable than this.
While it is quite oleophobic, it's hydrophobic qualities are a bit lacking. Still new-phone smooth feel to the display though.
I did the while process on my iPhone (original, 2007 device) which never came with an oleophobic coating. Here is how it looks after wiping my entire palm followed by my fingers on the display:

I imagine I'll probably have to eventually polish the Samsung oleophobic coating off and replace it with CarPro Reload once the OEM coating scratches more and more.
I'm disappointed in the S7's scratch resistance but hopefully I've found a solution. I will update as time goes on.
