LED flash for alerts

Situation: If you’d like a more discreet way of alerting yourself to notifications, you can enable light instead of sound alerts. So that your iPhone won’t vibrate off the table or interrupt your important meeting with brash sound alerts. You can use the iPhone’s flash to give you a sign.

Solution: Bring up Settings, then General, and Accessibility to enable LED Flash for Alerts. Now you can turn your iPhone facedown yet never have to worry about missing a notification. It will flash twice, you won’t be able to miss it unless you're really engrossed in your meeting, but we all know that's not going to happen. 

Undo deletion of email

Situation: A combination of Monday brain and incoordination has led to you accidentally deleting an email. Don’t panic, there’s a shortcut to undoing your mistake.

Solution: Keep calm and shake your phone. That’s right, there’s nothing wrong with your eyes. We said to shake your phone. And a box asking if you’d like to Undo Move will pop right up. Tap that to get your deleted email back. Shake again to Redo Move.
