I inherited a Google Pixel 2 XL Android phone that I cannot manage to upgrade from Android 9 to Android 10, let alone Android 11.
It doesn't see any update at all. When I go to the System Updates screen of the Settings app, I get:
"Your system is up to date"
Android version: 9
Security Patch level: November 5, 2018
Last successful check for update at
(in other terms, it successfully checks for updates, but doesn't find any).
I am an iPhone guy, with very limited knowledge of Android, but I am willing to learn. My computer is a Mac.
Note that this phone has been used for Android development in the past. it has a "Developer options" setting pages, and it also has been rooted. Could this influence the update process?
What can I do next?
