2. Shake To Undo
If you’ve ever typed or edited a picture and made a mistake, there’s no need to do it all over again. Just shake your phone- just a little so you won’t let go of it- and an option will appear if you want to undo the action.
3. Create a passcode with letters
Are you one of those type of people who want to guard their precious iPhone from those wanting to invade your privacy? Have they made it a challenge to crack your number code? Worry no more! With the iPhone’s handy little passcode, you can use letters instead of numbers so people can’t access your information. Go to Settings > General > Passcode Lock and turn off “Simple Passcode.”
