ANDROID users have been warned to check their smartphone today after an old version of the software was dropped.
Google has pulled the plug on Android 4.4 KitKat for good.
And it means anyone still using a device with it installed are at increased risk from hackers.
Android KitKat was first launched almost ten years ago.
If your smartphone is still using it you'll need to update to a new version of Android to stay safe.

But really old smartphones might not be able to, in which case you'll have to buy a brand new handset.
Fortunately, Google says less than one per cent of all devices run Android KitKat.
So the vast majority of people should be unaffected.
Most manufacturers had already stopped supporting devices running Android KitKat, which means their security is already weakened.
However, it's still worth checking.
Many apps and games no longer support Android 4.4 anyway.
Google's decision to end support for Google Play Services for Android 4.4 will limit the apps and services available on these devices even more.
