→ the response goes to the proper destination (ie screen) → user sees the response happening (total >10ms).

(Grand Total >80ms)

If anybody remembers that comment, as well as this one:

Here a team tried to calculate response times between several handsets. As you know the latest iOS came out on top, followed by the now-aging iPhone 4. Then followed by the top Android device at the moment (SGS4). Which was followed closely by the competitors (other Android devices, Nokia Lumia/WP8 device).

I want to see their follow on test, when they try it again on Android using a natively coded (C/C++) App. If the results are close enough to those of the regular Java App, then it will conclude two things we already know.

First is, Java is inferior but has closed the gap on C++ in certain fields.
The second is, the touch screen sensor is the bottleneck for latency in current devices.

For the next Note/GalaxyS I'd advise Samsung to use faster and more capable touch screen sensors to compete against Apple.

The good thing about this, now that its out in the open, manufacturers might take a step back from the lame spec war (ie dick measuring contest) and actually begin to bump up the overall quality of their devices.
