Samsung Galaxy Note 4 Fingerprint Not Found

I am working on an app where I use fingerprint. Everything seems to be good but when I debug my app, fingerprintManager.isHardwareDetected() returns false. Why? FingerprintManage

Solution 1:

Note4 don't support Android Fingerprint API.

You have to use Samsung proprietary PASS SDK: http://developer.samsung.com/galaxy/pass
