As of March 1, 2023, Android OS version 9.x and below will no longer be supported due to age and security requirements at the UU.
If you have a similar cell phone device, personal or business, you are advised to update it to a higher supported OS version or replace it. In the case of business devices (obtained on loan from UU), you can report this to your supervisor and a replacement device will be provided.
