How to identify if device has in-display Biometric fingerprint support?

Faced with the same problem some time ago - OnePlus 6T has no Biometric UI, at the same time Samsung A51 - has its own (custom) UI for Fingerprint API and another for BiometricPrompt API.I tried to watch for Activity window focus loss (For OnePlus - activity do not lose focus, at the same time BiometricPrompt UI leads to focus loss), but appear a problem with the Samsung device.

The only solution that I found, and it works for now:

1. Need to get the correct device name (for OnePlus for example, it should be not ONEPLUS A6003, but One Plus 6 instead)
2. Need to perform request to https://m.gsmarena.com/res.php3?sSearch=Device+Name, you should get the list with matches, usually, first one is needed
3. Parse HTML (from previews step) to get the link for device specification (like https://m.gsmarena.com/oneplus_6t-9350.php)
4. Now you need to perform a request to this link and again parse HTML and get the "Sensors" section. You should get a string like "Fingerprint (under display, optical), accelerometer, gyro, proximity, compass"
5. Split this string to get the list with sensors
6. Now when you need to check if an in-display scanner is present on the device, just check for "fingerprint" and "under display" for the same sensor.

Link with impl. that can be used as an example

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {    //Fingerprint API only available on from Android 6.0 (M)    FingerprintManager fingerprintManager = (FingerprintManager) context.getSystemService(Context.FINGERPRINT_SERVICE);    if (!fingerprintManager.isHardwareDetected()) {         // Device doesn't support fingerprint authentication         } else if (!fingerprintManager.hasEnrolledFingerprints()) {         // User hasn't enrolled any fingerprints to authenticate with     } else {         // Everything is ready for fingerprint authentication     }}
