OkayProve it, for each and every item I mentioned going back 5 years ago, since you mentioned years.
Live Photos- HTC Zoe.Been there since the HTC M7 days .In fact if you own a Nokia Lumia,I have been using this feature since 2011 in the form of CinemagraphLive Photos, continuity, hand off, self timer, night shift, low power mode, search bar in settings, FaceTime from spotlight, proactive, mass transit, quick type formatting, notes sketch, keyboard, wifi assist, back button, slide to select photo, hide photo, passcode length, battery usage plus others. other than that nothing new.
Search bar in settings-Touchwiz and Sense have had this for years.Every manufacturer added this
FaceTime from spotlight-Use Action Centre launcher.Swipe from the left and launch Skype
Proactive-Google Now has been doing this ever since it was introduced.I use Google Now over Siri on my iPhone
Mass transit-Lol.Google Maps had this for how many years now?
Quick type formatting-Swiftkey and almost any decent keyboard customisation app
Notes Sketch-Google Keep
Keyboard-Almost all the keyboards on Android are superior to iOS.Ever try the one handed keyboard like I did?You will wish you had one if you own the 6 plus
Wifi assist-You mean the feature which is pointless and gobbled up gigabytes of my Data Plan.The feature is bad and Apple should feel bad for not optimising it even now
Back button-Been there since 2010.Even better it doesn't block my carrier signal status
Slide to select-Again standard feature on Nexus.But I don't even need it on Android as using the File Manager makes me 10x more productive
Hide photo-Standard feature
Passcode length-Take any decent lock screen app on the play store and you can even set till 10 digits.The gesture unlock is so much better though
Battery usage-Lol it's been there since 2011
Continuity-Pushbullet app has been doing this since out was invented but I concede for Continuity and Handoff there is no proper solution until you root the phone
