We are using system popup dialog to scan fingerprint. We are not controlling its colors.

In search how to customize FingerPrint Dialog, I went through Android documentation on Biometric prompt. Due to variety Android devices and different scanners like fingerprint, face recognition and even iris scanner, Google provides with single solution as Biometric Prompt. In documentation they suggest to use system dialog. Here is what they say:

This system-provided dialog is consistent across the apps that use it, creating a more trustworthy user experience.

I think we should stick with system-provided dialog, without customization.
