They also typically don't work. I just got my Devilcase screen protector installed and it's a night and day difference over this one that I was using. The Supershieldz one had the metal grid and the phone just missed touch inputs constantly. Also the Supershieldz one was apparently missing a cutout for a sensor on the front, which I think is the light sensor. Explains why my screen was so dark constantly lol.

It's weird how inconsistent the quality is on these screen protectors. I have a Supershieldz on a cheap Moto G Power that I use for work and it's great. Edge to edge adhesive and it's quite thick too.

Edit: Actually just saw your Amazon review and do you know what the sensor is all the way on the right side of the phone? The tiny little dot one.

I see the one you have linked doesn't have any reviews or actual photos (the stock images are of an iPhone). Do you have any photos of it installed and is it fully clear or having a black border? If it's fully clear, is the coverage complete without any haloing on the edges?

Most of the models I have seen or tried have been one or a few of the following

​

• Lack a lot of coverage/protection around the edges of the front and swiping from any edge often does not work well as a result
  • Like this one - https://www.amazon.com/TQLGY-Protector-Xperia-IV-Tempered/dp/B0BNX5JD1M/
  • And this one - https://www.amazon.com/Mr-Shield-Sony-Xperia-IV-Replacement/dp/B0BD5333N2/
• Had a black border with adhesive only on the edges and terrible touch sensitivity as a result
  • Like this one - https://www.amazon.com/Supershieldz-Designed-Tempered-Protector-Scratch/dp/B0BGCMCNQX/
• Are edge-to-edge clear with full adhesive but have no cut outs for the camera so it could be blurry and also a big halo on all the edges because they're lifted up due to the curved screen edges
  • https://www.amazon.com/VIESUP-Xperia-Screen-Tempered-Glass/dp/B0BDF2ZDCH/
• Solve all the above but don't have 2.5D curved edges on the screen protector so the edges are very sharp as a result and not pleasant to swipe on
  • Like this one - https://www.amazon.com/YISPIRIN-Protector-Hardness-Anti-Scratch-Protective/dp/B0BLHH9NQ1/
• Some people claim a few that solved all the above but are offered and shipping only overseas
  • Like these ones - https://search.rakuten.co.jp/search/mall/%22xperia+5+iv%22+dragontrail/
• One model shipping in the US exists that does actually solve all the above, but it also costs over $40 for just one
  • This one - https://devilcase.us/products/2845?cat=3723

I have one more that's currently on order (this one - https://www.amazon.com/gp/product/B0BHW88LSJ/) that claims to solve all these issues as well and ships in the US for a far more reasonable price ($9) but there are completely no reviews so it's hard to tell at this point. Personally I'm not having too much hope that it will solve every issue so if you have any feedback or photos on your model it would be most helpful.
