Tempered Glass Screen Protector. Due to curved edges of the Galaxy Note 20 Ultra, traditional full screen glass screen protectors will generate huge halo effects on the edges. We have developed a Tempered glass screen compatible Galaxy Note 20 Ultra, which offers full screen protection without any bubbles or halo effects. This is accomplished with state of the art technology by placing hundreds of microscopic transparent dots on the screen protector to mimic the contact of your finger on the screen. Protect fragile phone screens from impacts, and scratches with this tempered-glass screen protector. Apply the ultra-thin sheet to the screen of a Galaxy Note 20 Ultra (6.9"). The hard-coated protector uses the power of military-grade glass to ward off screen-ruining scratches or dents. WORKS with Ultrasonic Fingerprint Unlock.
