As such it would be a bit more fragile in the touch area compared to traditional layered technology. Furthermore I can find no citation that the display features advanced glass of any kind such as Gorilla Glass, Dragontail or Sapphire crystal.
I would cover that bad boy up. I went with a 9H Tempered Glass and I think it added a premium feel to the screen and smoothed out some scrolling issues.
I did the same. I got rid of the standard plastic screen protectors and got a glass protector from Amazon. It does improve the scrolling feel and also it seems to be oleophobic, even if it isn't advertised that way. I end up with a cleaner screen for longer. For $7.99, it was worth it.
