Hi there and welcome
The upgrade only applies to the computer, not to the phone.
The phone receives updates free of charge, it is different to how the computer works.
When an upgrade for the phone is available you see a message appear on the screen of then and you tap proceed to perform the upgrade.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
