[absguy]

DEAR SAMSUNG

WHATSAPP HAS INTRODUCED FINGERPRINT UNLOCK FOR BETA USERS....

.I FOUND IT EXTREMELY FAST THAN THE FINGERPRINT SCANNER OF GALAXY A70.......PLS LOOK INTO THE MATTER AND MAKE THE FINGERPRINT SCANNER OF A70 FASTER LIKE WHATSAPP

whatsapp has no fingerprint sensor , it just uses device sensor . and it is not for BETA USER , it is with BETA VERSION. anyone can have this .

[absguy]

BOSS OBIVOUSLY IT USES PHONE DEVICE SCANNER.......BUT THE SCANNING IS FAST......BETA VERSION IS FULL NOW.CHECK BELOW SCREENSHOT......IT OPENS UP WHEN SOMEBODY DOES NOT WANT TO BE PART OF IT........WHAT I ALSO MEANT IS THE FINGERPRINT SCANNING ALGORITM IS VERY SLOWER THAN WHATSAPP...

compare here I am not even beta user but still i can use whatsapp beta version

compare the version , no one except whatsapp developer access can get this version now

version 2.19.226

I am not even signed Up for beta

whatsapp using the same algorithm. cause FIDO mechanism of biometric security is controlled by hardware so here whatsapp has nothing to do with speed of responce by fingerprint lock . it means device fingerprint sensor and backend is fast enough to handle all FIDO requests . whatsapp just do request the fingerprint sensor of the device to pass the auth . when device pass the auth using its algorithm than whatsapp recieves the input from socket and grant access

check another snapshot how whatsapp creates the socket to use device algorthim for fingerprint lock access . when someone trigger the sensor SAM in samsung creates appwindowtoken with the help of com.android.server.wm and whatsapp destoyes the id ( layer ID )


so fingerprint sensor is fast enough that's why whatsapp responded fast
