None of the roots were compromised. (Some of) Their own sub-CAs for TLS certs, which are also cross-signed by Sectigo (since their own roots are rather recent), are affected.
How you have that root cert on your phone with a 3 year old CA set I have no idea, presumably something updated your CAs in the meantime? (Also, aren't you incredibly exposed to the general onslaught of vulnerabilities from the past 3 years?)
