Facial recognition is useless on android in most cases. You can do facial recognition by software but unless it works much better than it does now, apple will not add it. And thats good.
Touchless operation on the other side works but is an artificial feature.
You don't need to distinct between hovering and taping if your ui works.
You only need it if you are a bad developer who thinks in desktop world for his app or if you are a marketing specialist who needs a feature.
touch support for gloves -> theoretical great, practical does not work so good in many real life situations. Problem here is the reduced resolution and exactness. You would have to modify the ui to make all elements bigger to ensure a good hit. Unless touchsupport for glove has same resolution it's not working perfect enough. But i agree, this is something nice to have basically.
wireless charging please no. Not with the current implementations.
First -> it takes way more power than wired charging. It also takes way longer. You also have to align your phone, make the phone heavier, limit your material choices, need additional shielding. For a gimmicky feature which is on ios not a real problem.
WHY wireless charging ? Because fidling with the plug is bad.
But with lightning there is no fidling. No this direction is right or wrong, or hard to hit hole (because of rounded plug). It is as fast as laying it on a mat.
But works faster and uses less power.
For Android i agree, using this ****** miniusb or microusb connectors is really pain in the ass.
NFC no thanks.
NFC is far to insecure right now, it isn't by any means a mainstream feature because of different protocols.
Why NFC if you have stuff like wifidirect for more secure pairing, wich also has much faster data transfer rates and is far more universal usable ?
Premium sound ... i would like to have no sound in all phones worldwide. Please use headphones for the sake of all the people in your surrounding.
There is nothing worse than driving in the train having multiple smartphones playing music with maximum power because people don't use headphones.
Yes better sound is possible as htc one shows.
BUT it is a feature i really really really hope for mankind will not be added to iphone. Just to have a little less noisy world.
IPhone has nearly since ios2.0 apps for ir remote. Add a small led to your headphone plug, finished.
But do you know whats much better ? use wifi solutions, so you don't need direct line of sight. Existing also since ios 2.0
LTE-A Support is useless for a phone right now if 90% of the network doesn't use it. Concentrate on whats used and existing, not on what could be existing in 3 or 4 years because then you have a new phone.
