However, after 6-12 months of daily use, this coating can wear off due to scratches or simply just by using it. As a result, the screen may not feel as smooth as it used to when it was new, and smudges can be very hard to clean off. This coating can be re-applied using aftermarket kits, such as the Fusso one:
But this kit usually costs about $30 for a 5 mL bottle. which is only good for one application for a phone about the size of an iPhone.
The other option is to use a plastic screen protector film. No need for a picture; they're ubiquitous. These protect the fingerprint resistant coating from wearing off, but also defeats the purpose of having a fingerprint resistant coating in the first place. Besides, they scratch very easily and ruin the appearance of an otherwise crystal clear display. Who would want to do that?
I use a tempered glass screen protector that supposedly has an oleophobic coating, but that quickly wore off after about 6 months of use. So I applied a matte screen protector on top of the tempered glass protector. Dat graininess tho!
Anyway, I came across 'Rain Clear'; a liquid designed to be applied onto car windshields to increase visibility in rainy weather. Raindrops bead up and roll off by themselves when the car is moving, keeping the windshield clear. Basically, it's a DIY hydrophobic coating. I bought this 135 mL bottle for $7 from Kmart (in Australia). I'm sure a similar product can be bought at your local variety discount store.
Application is pretty straightforward. I'm going to try it on a non-original Nokia X6 screen first.
Drop a few drops of it onto a piece of folded microfibre cloth, then rub the glass surface in a circular motion until a "haze" is formed on the whole screen.
I used this kind of cloth:
This is the haze:
After complete coverage is achieved, clean the haze off with a cloth (preferably not the same one used to apply the coating) dampened with water until it is clear.
The results (before/after):
And this is on the Note 2:
It makes quite the difference! Water droplets are a lot more spherical now, and it cleans off much easier, too. Now, let's try it on a STAR N9589 - a common Note 2 knockoff that definitely doesn't have a Gorilla Glass panel.
I'm going to apply it to the top half of the screen for comparison purposes.
When using the screen of the Note 2, it certainly feels smoother than before, but only about 50% as smooth as an original screen. Still better than nothing! I applied the coating two days ago. Let's see how long it will last!
