Samsung A50 fingerprint is not working with "DOUBLE TAP TO WAKE" turn off.

[karthikone]

My mobile recently updated to android 10 , I noticed that my fingerprint on lockscreen is not detecting (not failing/not mismatching,  it's just not activating) after "Double tap to WakeUp" option turned off. 

But activating double tap to WakeUp is consuming more battery than usual ,please help me to overcome this bug.

No problem in mine.

Anyone try this , Turn off the double tap to wake up , then lock your device wait for 10 seconds then click power button wait more 3 seconds then put your finger, it won't even recognize your touch.
(I've just factory rested my device but still same issue , I think fingerprint sensor is timing out at certain time after clicking power button.)
