My Android 15 handset doesn't have com.google.android.verifier process. It could be a Ulefone thing. They're especially pro-user (ex:root friendly).
Ex means "example" here right? Or do you mean ex as in the dictionary meaning of ex, as in, "formerly"?
Checked my Pixel 7 XL Pro and the app is installed and running (Version 1.0.866414232 com.google.android.verifier). I was able to force stop it, and disable it. Will check later to see if reenables itself.
