Hello there,
is anyone experiencing trouble using 3a ou 3a pro fingerprint sensor with 9h anti spy screen cover?
i find it difficult to use, especially when some apps need fp sensor validation. is there any way to make it work better? or adding 2 or 3 fp is the solution?
TIA
Mike_Moreira Hey, have you registered your fingerprints after you applied the screen protector?
Re-enroll your fingerprint after applying the screen protector. That should significantly improve recognition.
bagulswapnilb been there, done that. not working with the same capacity that was applied with the OEM factory screen protector.
Mike_Moreira Privacy screen protectors often interfere with smartphone fingerprint scanners due to their micro-louvre filter, which creates a physical barrier that disrupts the sensor’s ability to capture detailed fingerprint patterns.
Most fingerprint sensors (capacitive or ultrasonic) rely on precise detection of subepidermal skin layers or ultrasonic waves, and the added layer from privacy screens can attenuate or distort these signals. Additionally, improper installation (e.g., air bubbles) or incompatible thickness further reduces accuracy. While some compatible models exist (often labeled as fingerprint-friendly), users typically need to re-register fingerprints. A quick Google search showed me the internet is full of comparable posts with all sorts of brands and models. Privacy screens and fingerprint scanners often just don’t work well together, because they’re doing the exact opposite of what they’re supposed to do.
Daniel yes i did. i registered the same fingerprint 2 times, just to ensure that the sensor should work properly, but…
