Your Android phone 'might make a loud siren sound' this afternoon (if you are in the UK)

Don't panic! Despite the blaring siren, it's not an emergency, but a test of the emergency alerts system.

The UK government has issued a warning to Android users to prepare for the "small chance" of an emergency alert being delivered to their smartphone between 1pm and 2pm.

The alert might cause the phone to make a siren sound -- don't panic! -- and will say the following:

"This is a mobile network operator test of the Emergency Alerts service. You do not need to take any action. To find out more, search for gov.uk/alerts"

Don't want this happening while you're driving or working or having a nap this afternoon? The UK government have thoughtfully posted instructions for Android users on how to opt out of emergency alerts.

Search your settings for 'emergency alerts' and turn off Test alerts.

If you can't see Test alerts:

1.     Open your phone calling app.

2.     Use the keypad to enter *#*#2627#*#*

3.     Search your settings for 'emergency alerts' and turn off Test alerts.
