I watched the videos and was very impressed but one thing stands out as being the reason I will likely still use a tempered glass screen protector is the fact that IF the glass should break like from a fall G4 glass shattered while G3 glass just broke in half.
All the techniques used to test with gave impressive results but in my eyes a fall lands a phone in any number of various positions including a sharp jar to its corners which is entirely different than testing directly on a phone sitting on a flat surface. Should my glass break I don't like the dangers of it shattering all over the place. I think at least a tempered glass screen protector would help keep shattering to a minimum because the screen glass shards would stick to the protector.
I would love to see real life testing things like dropping phones from various heights and on different surfaces. Your phone hitting the concrete street is gonna take a harder hit than your phone hitting your kitchen floor kinda thing.
Perhaps this video will explain why I have so much confidence in the Gorilla Glass 4 solution. Corning has actually done "real life testing" in their drop tests and revised the formulation to protect the screen.
For me, maybe not for you, but for me I would much rather experience the full enjoyment of my display without the extra weight and filters between my eyes and the display. I love an unhindered view and given the strength of Gorilla Glass 4 (plus my own experience with the earlier generations of Gorilla Glass) the benefits of a clean uncovered screen far outweigh the potential risk. But that's for me, if I am wrong and break a screen I am ready with a Galaxy S5 in my drawer, and I would be willing to pay the piper for repairs if I am wrong and do break a screen.
For those unwilling or unable to risk breakage, by all means, protect your investment. It is my personal opinion that putting protection on the Note 5 display is like putting a bullet proof vest on Terminator IF and only if you have a good case that wraps around the front of the display.
I use a Tech 21 Tactical case and for me that's all I want or need.
Anyway Shaggy Kids, this video is for you:
