It’s one of the most popular social media apps around the world today, but believe it or not, Instagram has been around for 10 years.

To celebrate this milestone, Instagram has launched a surprise trick, allowing you to change the app icon to one of its old logos.

Instagram said: “To celebrate our birthday, this month we’re inviting you to change your app icon to your favourite.

“Thanks for being part of our story and using Instagram to share yours.”

The logos include the current yellow and purple ombre design, the classic camera icon from 2010, and the rainbow design to celebrate Pride.

To access them, simply open the Instagram app, go on your profile and tap on the three lines in the top right corner.

Tap Settings, then pull down from the top of the screen. This will reveal emoji on a dotted line, before a virtual party popper explodes across the screen, revealing the app icon centre.

Tap on the icon you’d like to use, and you should see a message on your screen reading ‘You have changed the icon for “Instagram.””

Instagram users are loving the hidden feature, with many taking to Twitter to discuss it.

One user said: “I know it may seem stupid, but I’m glad to have the old Instagram logo back. That modern one was just annoying.”

Another added: “Bit of fun from Instagram. Celebrate their birthday by switching up your Instagram logo.”

And one joked: “If you change the Instagram logo back to the old one you get the chronological feed back! Jk I f***ing wish.”
