If your iPhone or iPad is eligible for the latest OS update, you should be getting the iOS 13.4 and iPadOS 13.4 updates by now.
The biggest changes come to the iPad with Apple adding support for mouse and keyboard. The update allows you pair a Bluetooth Mouse, trackpad and keyboard with your iPad. The iPad OS has also been improved with an intuitive mouse pointer which adapts based on what it’s pointing to on the screen.
When Apple announced the 2020 iPad Pro, it announced with them a new Magic Keyboard which won’t be available until May. iPadOS 13.4 update brings support for the Magic Keyboard to older iPads as well as the Magic Mouse 2 and Magic Trackpad 2.
The other significant feature this update brings works in common with iOS and the iPadOS. With iCloud Drive folder file sharing, you can now share your folders with others via a link so they can access them the say you share on Google Drive or Dropbox.
Other features are nine new Memoji stickers, always-visible controls for delete, updated toolbar in the Mail app and some minor bug fixes.
