100% Fingerprint Unlock: Different from the ordinary privacy glass and TPU soft film currently on the market, our ONLY for S24 Ultra privacy screen protector made of PET has a thickness between the tempered glass and the soft film, which can perfectly solve the problem that the privacy film does not support fingerprint reader or the unlocking is insensitive. Please note: Bubbles, impurities or incomplete adhesion during installation may affect the effectiveness of fingerprint unlocking. Real 25 Anti-Spy: In view of the poor anti-peeping effect of 28 and 30 private films currently on the market, YWXTW has developed a true 25 anti-peep substrate, which significantly enhances the privacy protection without losing the true clarity of the phone screen. You can safely use your Samsung Galaxy S24 Ultra in any situation where you don't want others to see the contents of your phone. We suggest you redo your fingerprint after putting the screen protector on. Strong Screen Protection: This Galaxy S24 Ultra screen protector is made of Hybrid polymers and has good dimensional stability and scratch resistance.
