Like all things Apple, a simple google search shows what many already know. People have differing experiences and phones react differently depending on the hardware and software.A simple Google search reveals plenty of people have this problem and those who did have dealt with it by either getting the iPhone X or simply grin and bear it. The Youtube video in question is 100% accurate as regards showing the effects as if you see his other videos where he compares 2 iOS 11 versions, this effect is never observed.
Apple has given up on the home button iPhones at this point as even the budget model will use gestures this year and considering the fact that the new iPad Pro will also use gestures, its a given the 2017 iPad Pro is next on the chopping block. They will probably cripple another aspect of it to get those users to upgrade. I am staying on iOS 10 till 2019 which is probably when I get the next iPad with an OLED display running iOS 13
I, for one cannot tolerate that home button. Its a deal breaker to me and if Apple didn't have the iPhone X in the lineup I would have jumped ship to Android.
I agree Apple has given up on the home button and Touch ID. They are moving ahead.
As far as Youtube, IMO, many that attempt to show side by side comparisons are flawed.
The home button, I like its. Can’t use gestures to unlock a phone whilst it is being pulled from the pocket.
