When your phone won’t walk a tree
If your Android phone no longer generates tones that work when you’re asked to “Press 1 to … do something” Pixel support says go to Settings > Apps > Phone. Touch the three dots in the upper right, select “Uninstall updates” and restart your phone. Worked for me.
My list of recent calls was preserved. Yay. But presumably Google is working on a more elegant solution.
