If you could read it did not fail
The only reason there is such a huge push to make face id seem new is because they failed to get the finger print sensor behind the screen. So now they settle for a half measure with a "we meant to do this" statement.
Frankly my Iris lock works fine, voice unlock works fine, face unlock works fine.
You know what I can't get around. Not being able to manage my device like a computer. Needing iTunes to perform functions, not being able to install the apps I want from where I want, not having choices to theme my device. NOT HAVING THE PEN I PURCHASED THIS DAMN PHONE FOR.
Frankly your money is your money no one needs to quantify why they buy what they want. If you want an iPhone go get one but an Android forum on XDA is the last place to have this debate because it will go no where
Not to mention you shouldn't believe everything a company feeds you in light of bad press. Antenna-gate anyone? Oh we didn't implement a bad design, you are holding your phone wrong.
Being a fanboy is counter productive to the advancement of tech. Buy what you want and screw other people's opinions of what you want/can afford.
