If you use your device for "AirPlay" for wireless mirroring to an Apple TV, it is always best to keep your devices up-to-date.
Features I constantly use:
- Siri Suggestions
- Drawing, Sketching, and Checklists in Notes
- the "Back To" Button
- 4x4 Folders on iPads
- Now 16 apps fit in a folder page rather than 9 on the previous iOS
- Music automatically playing when you plug in headphones (or other audio device using a headphone jack)
- I keep meaning to set up Apple Pay.
- Split View****** This is by far my favorite update!
