I haven't used 3D Touch much.
Maybe I'm not sure how or what it's advantages are.
What do you guys use it for and on what screens that you find it helpful?
I use it all the time.
Homescreen:
- Calling frequent contact from the (Phone icon)
- Sending a text to a frequent contact (Messages icon)
- Opening Safari to a new tab from the (Safari icon)
- Getting a glance at the Weather (Weather icon)
- Going straight to Battery and Wifi settings (Settings icon)
- A lot of the third party apps that I use (Dark Sky, Facebook, Shazam, Sky Guide, Amazon, etc.) have great widgets/shortcuts from their homescreen app icons.
Within apps, you can preview links before going to them (Safari, Instagram, Facebook, etc.) and plenty of other things.
Also, from Control Center, you can 3D touch the flashlight icon to get different intensities of brightness (Low, Medium, Bright) which is really handy in certain settings.
There are many other great uses of 3D touch, but these are just the ones I could easily think of that I use every day.
