Android FingerPrint API isHardwareDetected returns false for Samsung Note 4

Question

I am trying to implement FingerPrint Scanner in my app.

I followed below tutorial: http://www.techotopia.com/index.php/An_Android_Fingerprint_Authentication_Tutoria

Answer 1

I'm afraid the Note 4 doesn't support the Fingerprint API (just the Samsung Fingerprint). You should try your code with another device if possible.

Answer 2

The issue is with the implementation of the Fingerprint scanner in some old Samsung phones such as the S5 and the Note 4.

Check this link Android M FingerprintManager.isHardwareDetected() returns false on a Samsung Galaxy S5 to see an example of how you can achieve this using the Samsung pass sdk.

You can also refer to http://img-developer.samsung.com/onlinedocs/sms/pass/index.html for the documentation of the pass sdk.
