7. Undo iPhone typing
Yes, we all type in text messages or notes on our iPhone and sometimes struggle when typing something we didn’t want to. There is no easy undo button to select for removing what we just typed.
The solution is to shake your iPhone to bring up the Undo Typing prompt. This will remove your last break in text. Handy!
8. Easiest way to hide iPhone unused Apps
The iPhone iOS doesn’t let us delete built in system apps. While annoying, we can still hide them so they aren’t on our home screen taking up space.
Create a new folder on your home screen and drag all the Apps you want into this folder.
Finally, move the folder off to a home screen page you don’t use – this way you will never see it!
