Didn't put screen protector on my HTC Desire Z (4 years old), Samsung Galaxy S2 (2 years old), and Samsung Galaxy Note 2. All of them are gorilla glass, and all of them are being used by our family ever since we got them. So far there are no scratches nor blemishes on the screen, even though kung saan saan na nalaglag ang mga ito (less battle exposure on the Note 2 since it's quite new), the screen looks the same way as the time we first opened it from their boxes.

Yung body lang ng HTC namin ang mukhang luma.
