Samsung A50 - Indisplay fingerprint sensor issue

Device brand and model: Samsung A50

Ratio version: v3.2.4

Problems encountered when using ratio: I have disable color for whatspp in Ratio. After locking the phone, when i get an incoming call on whatsapp and after answering & ending the call, in-display fingerprint sensor glows with white color instead of usual green color. Because of this fingerprint unlock is not working.

Need to ensure that indisplay sensor always has green light only.
