WANT to expose a snooper looking through your phone? There's a simple setting that'll catch them red-handed.

But you'll need to switch it on ahead of time or it won't work.

The trick works using Screen Time, which is a built-in Apple feature on your iPhone .

It's switched off by default, but you can turn it on to track snoopers.

Screen Time is meant to be used as a way to keep track of how much you're using your mobile.

And you can even use it to set limits – even on specific apps – if you think you're spending too much time scrolling.

Once you activate Screen Time, it stays on in the background.

And it'll pull together loads of data about how you're using your phone.

This is the key to seeing if someone has been having a peek at your mobile while you're not looking.
