Fingerprint Security cannot be place in my one plus two.

1. Hit <enter>
2. to insert another list item, and

<enter> twice in a row to end the list. To get subitems, repeat the bullet character once for each level of indent you want (fingerprint hardware not available)So, my i wanted to keep fingerprint scanner but do not read my fingerprint and always shows 'FINGERPRINT ENROLLMENT DIDN'T WORK. TRY AGAIN OR USE A DIFFERENT FINGER' what should i do for that?
