Installing Flex on your device.
When using the auto-upgrade on your Flex device as the server has been upgraded to the latest version
You will need to do the following:
Logout of flex
Login to flex
You will then be told you are using an old version (x.x) and you will be asked to upgrade.
Click on Yes - System will then download a file, it will show the progress
It will then ask to be installed, you say yes to install.
Once installed it will close flex
Logon to flex version, the version number will change for example (v1.8.1 to v1.9.0)
If you received a failed installer message after you click Yes or it just closing the application, there is some setting that needs to be changed on your device.
Go to Settings
Applications and Notifications
Advanced (bottom)
Special App Access
Find “Install Unknown apps”
You should see flex, select this and allow from this source
Then go back to step 2 again
Once you have changed this for the first time, all future auto-upgrades will be fine.
