How do I know there is a device update available, how do I check I have the latest SW?

NOTE: When a new Firmware/Software is available, notifications are sent out to all CAT S41 devices.
On the home screen an Icon will show in the notification panel. When the icon appears you can drag down the notification panel and select.
To manually update:
1. Go to settings menu
2. Scroll to the bottom of this screen, and select “About phone”
3. Select the “System updates” option
4. Select the “Yes” option
5. The device will check the battery charge level and may ask you to further charge
