im sure all of us who used SGP Ultra Optics Anti Fingerprint will recommend it to you!
Crystal clear, and anti fingerprint! good touch to it too
I would say that Ultra Optics has it's own drawbacks.
First of all, it WILL reduce brightness and clarity of the screen. The screen is noticeably dimmer after you applied it
Second, it will NOT resist fingerprints. Yes it's not as fingerprint magnet as clear ones... but still attracts oil from fingers and face. And worst part is, the smudges are very very difficult to clean once it's there. Simple wipe on your shirt or cloth will not clean it... have to apply abit of water to totally clear it. I would say my screen has plenty of noticeable smudges by the end of every day... and it looks gross after several days without cleaning.
If you look around, some forums even say that Ultra Optics is the worst of both world... reduce clarity and brightness + still attract oil and v difficult to clean.
I personally won't say that it's the worst of both worlds... just that it's not as "perfect" as you thought it'd be. What I like about Optics though, it's very smooth and easier to Swype on.
One more thing, it will produce a kind of high-pitched squeak when you swipe your finger... This gets extremely irritating once you start using the S-pen. Played Fruit Ninja with the Spen the other day and couldn't stand it!
