Hey @Xyrec,
I get it, however, the reason why I asked is if the screen protector is too thick or the light transmittance is too low, it will affect the penetration of light and cause the signal received by the sensor to change. It is recommended to choose a protective film with a thickness of less than 0.20mm, a transmittance of more than 90%, and a haze of less than 1%, which will get a better fingerprint recognition effect. If you encounter the problem that the fingerprint is not being identified, it is recommended that you remove the sticker first to check whether there is any abnormality.
