iOS 9.3 released. New feature "Night Shift" and many other feature improvements.

Earlier, the iPhone SE and iPad Pro 9.7 inches were announced, and iOS 9.3 was also released along with them.

The contents of iOS 9.3 are as follows.

• Night Shift
• Improved memo functionality
• Improved News functionality
• Improving healthcare functionality
• Apple Music improvements
• Improved photo functionality
• iBooks improvements
• Improving educational functions
• CayPlay functionality improvements
• Dolby Digital Plus
• Hardware keyboard improvements and fixes
• Other improvements
• Bug fixes for enterprise features
• Accessibility bug fixes
• Other fixes, performance and stability improvements

Of these, I'm curious about the new features "Night Shift" and improvements to "Memos".

When "Night Shift" is turned on, the display color will automatically switch to a warm color based on the sunset time.
It may help you sleep more comfortably...is it true?

I'd like to try out the sorting function in "Memo" and the ability to lock it with Touch ID or a passcode right away.

Finally, we have fixed the issue where the iPhone would not start up if the date was set after May 1970
