This might be the time to add that Ultimate Shield did not tell me to write this, I bought the screen protector because I have used their OP5 tempered glass in the past and was satisfied with that one. In case the pictures don't show on your screen, I've attached them in a zip file down below.
What do you get?
For £11.99 (~14€ / ~15$) and free worldwide you get one screen protector, instructions, dust removal stickers (which I forgot when taking the picture), a microfiber cloth and a wet cloth.
I bought it because I wanted a tempered glass screen protector which is curved so I can protect the whole display including the curved edges.
What about applying it?
The instructions are basically useless, since we're dealing with a screen protector which sticks to the phone with the adhesive side, so no bubbles, no "vacuum" or anything like that, as long as the display has been cleaned before nothing can go wrong, just make sure that the side slim black bar is alined with the top of the phone. Oh and you should remove the preapplied screen protector before putting this one on the display. After that it is important to apply preassure on the border of the screen protector to make it stick, and this is where things get critical, at least that is what happened to me. Even though it looks like I've prefectly placed the glass on top of the display some parts of the protector simply won't stick, or at least stick for a few minutes. I have added some photos where you can see a tiny gap. Keep in mind that I have applied A LOT of pressure on those parts, more than enough. The screen protector has rounded corners and a curved edge, it covers about 99 percent of the display.
What about colours and sharpness of the display with the screen protector?
After applying the screen protector I haven't noticed any kind of weird colour shifting or rainbow effect. It still looks as sharp as before, but due to reflections the edge of the display has some minor rainbow effect. I only notice that at a specific angle and when the background is white. Oh and it doesn't seem to cut off any part of the screen.
What about the fingerprint reader?
After deleting the old fingerprints and adding new ones with the screen protector applied the fingerprint scanner works 99/100 times, it might take a split second longer than without it, but I didn't have any issues.
What about the touchscreen and gestures?
This is where I got frustrated. After using the phone with the tempered glass I instantly noticed that the touchscreen wasn't as responsive as it was before. "alright", I said to myself, "It is completely normal that it feels different now". Unfortunately this is why I would personally not buy this screen protector again. I had to apply more pressure than ususal when tapping on an icon and so on. Sometimes the touchscreen didn't register even though my finger clearly touched the glass. This was very annoying when using the keyboard, in almost every sentence at least one or two characters where simply missing because the touchscreen wasn't as responsive as before. Same story with gestures, you need a lot more pressure and when swping up or down in order to open the app drawer or notifications it sometimes works but sometimes it takes up to three tries in order to get the gesture to work. In comparison, without the tempered glass screen protector I had no issues at all.
Applying it was easy but when I did it it didin't stick as good as I hoped it would. The tempered glass screen protector doesn't really change colours, which is a good thing. THe touchscreen experience was comparable with one of those older smartphones where you had to use more force and it wasn't as accurate. Overall, I can not recommend it for the price, unless you use the touchscreen with a lot of force. If you think that I didn't apply it correctly feel free to "call me out" in the comment section and tell me how you would have done it.
Since the tempered glass didn't stick very well anyway I went ahead and carefully removed it and moved it about 1mm downward. Unfortunately the touchscreen is still not responsive enough to use the keyboard without any issues which is why I contacted Ultimate Shield directly via Email. (still waiting for them to reply)
They answered and after looking at the images I send them they said that it might be faulty because according to them the black adhesive should stick much better than it did in my case. They were kind enough to give me a refund! If you bought one and had a much better experience please tag me so I can quote your opinion!
