Do Restart Phone 📱 , do try to add new fingerprints and do check ✔ is there any hardware damage

If Not Work Visit Care #solution

Same problem (M31).
Problem started when I last visited service centre(I failed to check it) . I think they didn't plugin the connectors back.
Anyways visit service centre if restart didn't solve the issue.
