As well as updating your apps, you should periodically check for updates to the operating system.

Before you begin to download the update please ensure you are connected to WiFi rather than using your data connection.

How do I check for system updates?

1. Swipe from bottom of your screen upwards to display all the apps installed on your phone.
2. Click ‘Settings’.
3. Click ‘Security’.
4. Click ‘Security Update’.
5. Click ‘Check for Updates’.

Install any updates that are available.  If you are asked whether to download them over a 3G or WiFi connection always choose WiFi.
