Scare your friends witless! Here's how

We’ve already shared some Halloween treats with you so now it’s time for the tricks.

The O2 Gurus have come up with a top way to spook your friends and cement your reputation as a tech terror using nothing more than your Android phone. We grabbed our trusty Samsung Galaxy Alpha and waited until our victim was asleep…

Want to replicate our shock tactics? It’s fiendishly simple, here’s how:

1. Go to Google Play and download the free Scary Prank app

2. Wait until your intended victim nods off (we suggest singing lullabies and plying them with soothing camomile tea to hurry things along)

3. Open the app. Switch sound effects to ‘on’ then set the timer for as long as it will take for you to hide.

4. Quietly sneak over and place your phone by your sleeping friend then creep off to hide nearby.

5. Laugh maniacally from a safe distance as your friend jolts awake in terror!

Happy Halloween!
