LK3 Pack Screen Protector for Samsung Galaxy S21 Ultra, Self-Healing TPU Film, Anti-Scratch, No Bubble, Touch Sensitive, Support In-Display Fingerprint Scanner, Alignment Tool IncludedGlobal Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

I put a screen protector on all my phones so I've probably used about I think 30 different brands and types of screen protectors over the years. On the S23 Ultra (possibly other S23 models), the stick on (non glue) tempered glass protectors either have an ugly fingerprint mark on the glass or if not, the fingerprint area barely works and is too frustrating.The tempered glass protectors that use a liquid glue you cure with a UV light, the fingerprint reader works about 85-90% as good as having no protector but the install process needs to be carefully followed and can be a bit messy - definitely not for those that are impatient or can't study and follow instructions well. They also are easily accidentally lifted off the glass if you catch the edge taking your case off.These TPU film protectors are the best compromise in my opinion. They are cheap, and this type is easy to install, have a feel nearly as smooth as tempered glass, and self heals from minor scratches. And contrary to popular paranoid belief, tempered glass does not prevent your underlying screen from shattering so the extra protection of tempered glass over film protectors is debatable. Everyone just ASSUMES glass must be tougher. When in reality it transfers sharp impacts to the underlying glass. I've never had a cracked screen from a TPU protector, but I have friends that have had cracked screens that had glass protectors.If you want to fork out big bucks for a Whitesone tempered glass protector and manage to follow instructions well, you'll be good. But really, for the average user, this type of TPU protector is both WAY easier to install, offers just as good of protection at least from surface scratches and is much more economical.The only downside is that the near-glass smooth feeling will diminish over time as the TPU protector gets minor wear. But it's so cheap, just install another one every 6-12 months to restore that glass-like smoothness.Other big benefit of this type of protector is it is so thin and wraps the curves so well there's virtually no visible edge to it where the tempered glass you can both see and feel the edges as you swipe from the left or right screen edge. It's just more noticeable and prone to coming off if you aren't careful when you remove your case.All things considered, this type is the way to go. But unfortunately many are obsessed with tempered glass to be able to sleep at night. LOL. You may need to retrain fingerprints if you are switching from a glass protector but the fingerprint reader works 100% as good using this TPU film protector as no protector as opposed to 85-90% as good with even the top notch tempered glass protectors.Also note if you have small bubbles not caused by dust or lint, they will disappear over time due to the self-healing. And also note the very light crease line in the center will also disappear. So RELAX. In addition, this protector is not any more prone to fingerprints than the high end tempered glass protectors remarkably!End of my novel. LOL.

More easier to apply than other protectors made it a real hit with me. The extra protectors made the overall price reasonable. It survived a two year old attempting to write on it with a pen which is what caused the other protector to fail.

After using this screen protector for a short time, I am genuinely pleased with its performance and quality. This product truly stands out for its efficiency and potential to enhance your phone's functionality. However, prospective buyers should be prepared for the setup process, which can be quite a challenge.Pros:Exceptional Quality: The product feels robust and well-designed, assuring long-term durability and reliable performance.Enhanced Performance: Once installed, it operates flawlessly, integrating seamlessly with your phone's existing systems. It delivers on its promises and is easy to use.Cons:Challenging Installation: The installation process is not as straightforward as I had hoped. The main issue is the instructional video provided on Amazon. While it's clear that the video aims to be helpful, it progresses too rapidly, glossing over details that are crucial for proper installation.Lack of Detailed Instructions: In addition to the video's rapid pace, there are no written instructions included in the package. This lack of instructions leaves you second-guessing your steps, which is not ideal when you are dealing with installation.Despite these installation challenges, once the product is up and running, it performs exceptionally well. I would recommend setting aside ample time for installation and possibly consulting additional resources or professional help if you're not confident in your DIY skills. Also, pausing and replaying certain segments of the video can be beneficial.In conclusion, if you're willing to tackle the installation, this screen protector is a worthwhile investment. So far, it has been a premium product that delivers on performance and durability, albeit with some effort on the setup front. Your patience and effort during the installation phase will be rewarded with excellent usability and functionality. A solid purchase, but do keep in mind the installation hurdles!

This screen protector exceeded my expectations. It fits my Galaxy S21 Ultra like a glove — edge to edge coverage without interfering with the curved screen. The installation was super easy, with no bubbles at all. It doesn’t affect the touch sensitivity or fingerprint sensor, and the clarity is crystal clear. It feels just like the original screen. I've dropped my phone once since applying it, and the screen protector did its job — not a single scratch on the screen. Highly recommend!

Ignore the cracks on the phone, they were from previous incidents lol. But I love this screen protector, it’s so clear it looks practically invisible! The pictures I took is when I already applied. I absolutely love that it came with guides too, very rare at this price point from what I’ve seen. I’ve always hated installing screen protectors because they always turn out lopsided, but not anymore because of those guides! I also watched their videos and it was very easy to install. It sticks pretty well too, will update when it eventually comes off. Fingerprint works like usual after install.Tips: make sure to really clean off any dust surrounding the environment and then your phone before you take the screen protector out of the bag or else you’ll get air bubbles due to the dust flying around and sticking.You get 3 in the pack so I think it’s very good. Would recommend and would buy again!

I'm a repeat user of these LK screen protectors for my phones - easy to install (clean & no bubbles), and they work great!
