I never use it on my 6S, other than the first day playing with it. Why? Because it's not part of the normal UI yet. When I use other devices like iPad, Android, Windows, etc, there are no 3D Touch. Compare that to multi touch like pinch and zoom where it became "standard" part of touch UI.
You just peek at them using 3D Touch on the messages list.
I'm a little disappointed with 3D Touch. I was hoping more apps would take advantage of it. I think in the future Apple will build it deeper into iOS. But will developers? I've seen mockups such as the one where you could customize control center by 3D Touching on it. I could see it being used more to customize things in the future, much like it's used on the Apple Watch to customize the watch face?
My favorite feature is using the keyboard as a touchpad for the cursor selection. It's just kinda finicky sometimes, like when you let up your finger it will jump over a character or two. I don't use the multitasking gesture because it was kinda difficult to activate at first. They've made it easier with software updates but I still haven't taken up using it very often. I need to force myself to do it because I think that could be really useful. I hope they add 3D Touch for Today View and Notification Center. It's kinda ridiculous that you can't peek at notifications like email from there. I also wish that widgets in Today View were 3D Touch capable. For instance, my Fantastical calendar would be great if I could 3D Touch on an appointment and get more details quickly without having to open the app. I think there are other possibilities as well, such as 3D Touch swipe from the right edge of the display (so opposite of the multitasking gesture) to open a customizable area, kinda like what is to the left of the home screen but better like Google Now.
Very good point. I think that was my biggest issue with it. It didn't actually increase productivity. For example, the messages app could allow a "peek" into the most recent message/messages. Basically a window into the actual message app main screen. When I am in the app, what good is peeking into a message when I can easily click and swipe in and out of it. It just seemed like the choice for actions was not well thought out.
I use the app switcher a little, but often it's quicker just to double tap the home button.
The keyboard trackpad cursor thing is good, but unreliable, so I rarely bother to try it anymore.
"Peek and Pop" is completely useless in Safari, Mail, etc...as it's quicker to just open the link/email/message as normal then choose "Back" once you've read it. I really don't understand why people use this. It's a decent function for photos though.
The app shortcuts are the most pointless out of everything. So unintuitive.
Overall, I think 3D touch has a lot of potential, it's just been poorly implemented.
My suggested improvements/features:
- App Shortcuts. Instead of having random things that only some people would use, how about have them be generated dynamically. E.G. In Safari, I would rather it show a list of say, the last 3-4 tabs I navigated to, plus a New Tab button, instead of things like Reading List that I never use. However, if Reading List is a frequently used function for other users, it should be intuitive enough to display it as a shortcut. Same goes for contacts, messages, settings, etc..
- App switcher. Instead of an awkward press that only works in a precise spot on one side of the phone, have a deep press anywhere on the screen (When not on the home screen) to toggle the app switcher. Or even a deep press combined with a gesture, like a deep press + swipe up like the iPad.
- Keyboard Cursor selector. First, make it work all the time. Not 1/6 times as it does currently. Secondly, adjust it so once activated, you can use two fingers to select text, or one finger to just move the cursor around.
- A deep press (or two) on selected text copies it to clipboard.
- A deep press on the battery toggle Low Power Mode (while on the home screen).
- A deep press on the cellular logo toggles Airplane Mode (while on the home screen).
- A deep press on a song in the music app, adds it to Up Next.
- A deep press on cover art toggle the artist view in the Music App.
There are so many ideas to make 3D Touch better/great, I could go on all day.
Pretty much this.I use it from time to time, but it isn't a life-changer. I would not miss it if they took it away.
