1 Keeping It Unlocked
This is advice that, hopefully, everyone has already heeded. But in the off-chance that you’re not using a passcode or other security to lock your device, you should strongly reconsider. Seriously, it’s one of the most basic but important steps you can take on your iPhone.
Leaving your device unlocked leaves it and all of your data vulnerable if it’s ever lost or stolen. Just think of all the social media or other apps that you don’t need to log into every time you open them. A thief would have the exact same access on an unlocked iPhone. That’s not even considering all of your texts, contacts and pictures. Just lock your iPhone.
