I am having problem with Biometric verification whenever I try to log into my banking apps since I bought iPhone 16 Pro Max

Since I have bought the latest iPhone there seems to be a built-in glitch in its software due to which I along with two of my other friends have failed to log into our banking apps as whenever we try to sign in the banking software directs us to the biometric verification where the camera fails to scan the fingertips as it auto focuses thus clicking a blur image as a result the scan fails every time. Kindly do guide me how to switch off the auto focus while logging into our banking apps or rectify the software glitch of iPhone so that this miserable situation can be done away with
