Galaxy S9 Plus Screen Protector, Full Glue Nano Optics Edge to Edge Case Friendly Full Coverage Tempered Glass Protective Cover Film for S 9+ Samsung S9+ Phone

Don't buy this. it's impossible to get a flush finish without bubbles, namely because this thing comes with a bottle of glue to pour all over you screen in order to get the protector to stick.

Works great

After viewing an institutional video link, that had to be sent by the manufacturer, this product was easy to install. I liked that it did not take away from the touch sensitivity of the phone. I disliked that only having it few weeks, it shattered the first time I dropped my phone. However, it did protect the phones screen from breaking.

Excellent glass screen protector for the curved screen phones (Galaxy S8 and S9+). The finished product looks and feels like it is part of the phone. It is perfectly clear with no bubbles nor any other visual imperfections. The touch sensitivity is excellent and consistent across the screen with no need to adjust the sensitivity setting. This glass fits the Spigen Rugged Armor case just fine (https://www.amazon.com/dp/B0789S2MPW).The liquid glue installation is a little daunting and messy but quite manageable. No special skills are needed, just patience. Get the installation video from the vendor and watch it.Here are a few pointers:Put the phone on the work surface and pour a small puddle of water onto the center of the screen (and be ready to quickly wipe it dry). If the water does not stay in the center, the work surface is not level enough. Fix it or find another level surface. Otherwise, the glue will flow all over the place before you can position the glass.The provided wet-wipe is quite small so use isopropyl alcohol and a towel to thoroughly clean the screen. A canned compressed gas duster is handy for gently blowing the dust off just before installation.Tape the buttons, ports and earpiece. This will help make the cleanup easier and you will not need to dig glue out of the crevices. Use any tape that is easily removable like painter's tape. For the buttons and ports, the tape can be started on the screen edge itself since the glass protector does not cover the entire edge. Make sure that the areas above the buttons are fully covered because the glue will run downward. When taping the earpiece, first lay the glass protector in position on the screen and then put the tape edge up against the top edge of the protector. This will serve as an alignment guide later. Even using tape, a little of the glue may still get through because of it being paper so use a second layer of tape.Do not shake the bottle of glue. This may aerate the glue creating tiny air bubbles. If you have shaken it, let it sit for a while before using it.Keep the tip of the glue container close to the screen and let the glue out slowly otherwise it can splash onto the screen creating bubbles. When the glue stops flowing, do not squeeze the container to get every last drop. There is more than enough glue and squeezing the bottle may force air bubbles into the puddle of glue. Use the tip of the bottle to breakup any bubbles.Hold the glass protector in place and rest the bottom end of it on the screen. Gently lower the top end down onto the glue. Once the glass touches all of the glue, it may be released to let gravity do its work. The glue has a fairly low viscosity so it only takes about one minute to spread completely. Let it sit for a few extra minutes to be sure. You can soak up the excess glue as it comes out of the edges.Do not press down on the glass protector once the glue starts to spread. If you think there is a big gap between the glass and the screen, there probably is not! Any gaps will be filled by the glue. Pressing down on the glass will deform its natural shape and force glue out the sides. When the pressure is released, the glass will return to its natural shape and suck in air causing bubbles and create a void along the edges.The glass may be gently touched and slid into position; the glass slides easily before the glue is cured. The glass is curved so it will self-center itself left and right. You just need to slide it up and down to the desired position. Pretest the glass with your case and note the desired position before you start. Lining up the tape that is covering the earpiece with the top edge of the glass is a good way to do this.Be careful about cleaning the edges too early or too aggressively. You may end up wicking away some of the glue from the under the edges causing a void and bubbles.The provided UV lamp works but requires more time because it covers a small area and it is quite weak so the glue may not fully cure. Make sure that you are ready to go before you turn on the lamp. It is powered by tiny batteries so there is only about ten minutes of good light before it gets too dim. Do yourself a favor and get a better UV lamp that can be left on for a long time, like this one: (https://www.amazon.com/dp/B06XXVK458)The excess liquid glue can be wiped up with a paper towel; do this before removing the tapes. Any cured glue can be rubbed off the case. For the final cleaning, the phone can be wiped with a towel and alcohol to remove any smudges from the glue.
