NEGATIVES
- Privacy: yes, it does add privacy at an angle BUT it makes your S23 Ultra look like it has a 320x320 resolution. You can see the HUGE "pixel-like" squares (the technology behind the membrane's "privacy"), making you think you'll need glasses for myopia soon.

- Application: the edges (curved on the S23 Ultra) come off. Does it need time to settle? Maybe. Anyway, for the 2 hours I've had it unused, every now and then I go and straighten the edges that lift up. I hope it gets better by tomorrow...

- Touch/Feel: It is NOT matte. And it is NOT glass. It is a SUPER-glossy SOFT MEMBRANE (almost more reflective than the phone's own screen). Your finger does NOT glide smoothly over it AT ALL. On the contrary, it "sticks" (membrane, you know?)

- Fingerprints: It LEAVES fingerprints just by looking at it. And to wipe them off takes effort, they don't come off quickly like on the screen itself where you can remove them with one swipe. They need to be rubbed for a while. I'd call it more oleophilic than oleophobic.

- Lack of instructions: there were NO installation instructions in the package, except for how to initially clean the screen from dust. Since it's a flexible, soft membrane (enough said!), you need to pay attention to gradual installation and NOT all at once as you would with glass. As someone experienced in applying vinyl stickers, I used a special spatula and STILL had trouble. And I wonder: how on earth is a regular user with no idea about membranes supposed to install it without putting it on crooked or leaving bubbles?

POSITIVES:
- The fingerprint scanner works without issue
- The camera cut-out is in the correct position
- Around the edges it is a millimeter smaller so that cases don't lift it up (IF it ever settles in place)

For a screen protector, it's good, it sits easily but it's quite "soft" so if there are bubbles, you can scratch it to remove them. It has a matte finish. For privacy, no way. The title is completely misleading. Also, the fingerprint sensor on the S23 Ultra doesn't work for any reason, so if you have that kind of unlocking method, don't choose this...

Very good film, Matte surface does not leave fingerprints... fingerprint works excellently.. The only downside is that if you put a Mobilfox type case on, it will slightly lift it on the sides.
