I had similar issues after I got the screen protector.
Now its much better after the below steps.
1. After you put on the screen protector/tempered glass set the fingerprints again.
2. Add multiple fingerprints of the same finger.

okay if protector is interfering how come the system application is not showing up .. there must be a fingerprint application for it to work

[tsing]

the applicatiob itself is not showing up

Since you have already done a factory reset you should visit the Service Center.
