Android M Fingerprintmanager.Ishardwaredetected() Returns False on a Samsung Galaxy S5

Android M FingerprintManager.isHardwareDetected() returns false on a Samsung Galaxy S5

Finally solved. It looks like android default API is not able to handle some Samsung devices, so the solution is to add the Samsung libraries for this issue.

You can find some documentation and the libraries here: http://developer.samsung.com/galaxy/pass

After add the libraries, you have to add a new permission to your manifest:

<uses-permission android:name="com.samsung.android.providers.context.permission.WRITE_USE_APP_FEATURE_SURVEY" />

And finally, you could use this method:

private boolean isFingerprintSupported() {
  boolean isFingerprintSupported = fingerprintManager != null && fingerprintManager.isHardwareDetected();
  if (!isFingerprintSupported && SsdkVendorCheck.isSamsungDevice()) {
    Spass spass = new Spass();
    try {
        spass.initialize(context);
        isFingerprintSupported = spass.isFeatureEnabled(Spass.DEVICE_FINGERPRINT);
    } catch (SsdkUnsupportedException | UnsupportedOperationException e) {
        // Error handling
    }
  }
  return isFingerprintSupported;
}

Android FingerPrint API isHardwareDetected returns false for Samsung Note 4

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.

Android FingerPrint isHardwareDetected not working

It is mandatory for Android Fingerprint API that the android version is equal or superior to Android 6.

It seems that this is a common problem with multiple Samsung devices such as Galaxy S5 running Android 6+:

Android M FingerprintManager.isHardwareDetected() returns false on a Samsung Galaxy S5

FingerPrint API isHardwareDetected always returns false

The only solution is that you can implement the Samsung Pass Api for those devices:

android fingerprint sensor API

After a bit of investigating it seams that Samsung did not implement the Android Fingerprint API support for some of their devices, thus the FingerprintManager Class wont respond as intended. I suggest using the Samsung PASS SDK which can be found here : http://developer.samsung.com/galaxy/pass.

Samsung S5 and Note 4 are not compatible with Android's Fingerscan APIs. It always returns false for FingerprintManger.isHardwareDetected(). Where as it works well on S6, S6Edge,S7 and S7Edge.
