When it launched back in early 2021, the Samsung Galaxy S21 Ultra cost $1,200. You can get it for a lot less these days but it remains a very capable device. With that in mind, it makes sense that you'll want to protect it — especially that gorgeous display — from scratches and drops. That's where a screen protector comes in.
With its ultrasonic fingerprint sensor and curved screen edges, it can be hard to find great protectors for this Samsung device. Worry not, because this list will rank some of the very best S21 Ultra screen protectors you can buy today.
#1 Whitestone Dome Glass
For those in the know, you'll agree Whitestone is one of the more respected names for screen protectors. That's why it shouldn't be a surprise that the Whitestone Dome Glass screen protector for the S21 Ultra is a top choice.
Tempered glass is rare for curved screens (a Samsung staple since the S6 Edge), but they've done it. It curves gently at the edges to give your display full protection. The installation process is a bit technical and this is definitely on the high end in terms of price, but you get quality that matches the price (plus, it's a two-pack!).
#2 Otterbox Alpha Flex
Otterbox is known for making the most rugged cases on the market, so why wouldn't you trust them to protect your phone's screen? In comes the Otterbox Alpha Flex for the S21 Ultra.
This is a TPU screen protector, which means it is flexible and film-like as opposed to being made of tempered glass. These protectors are generally cheaper and have mild self-healing properties, so you might prefer this one!
#3 Spigen NeoFlex
The Spigen NeoFlex is a TPU protector that works great for the S21 Ultra. It uses a wet installation process, which can be tricky to get the hang of, but when done right, you should have a clean installation free of bubbles. Fortunately, it's a two-pack, so you can try again in case of errors.
If you use any Spigen case with your device, this is guaranteed to be compatible with it. That means no edges lifting when trying to put on or take off your phone case.
#4 AACL Screen Protector
If you're more of a tempered glass person when it comes to safeguarding your display, this AACL screen protector two-pack will do the job nicely. The necessary tools for precise installation come included in the box and it is incredibly simple.
The company advises increasing touch sensitivity in your device settings and re-registering your fingerprints on that huge fingerprint sensor once the screen protector is installed, and that seems to be key in avoiding complaints in that regard.
#5 amFilm Elastic Skin
amFilm is something of a quiet contender when it comes to screen protectors. If you're looking for a very high chance that you won't deal with failed fingerprint scans half the time, their products are the way to go.
amFilm Elastic Skin is a TPU protector for the S21 Ultra that's able to heal minor scratches and handle mild drops. Plus, with dry installation and an alignment tool in the box, installing this is as easy as can be.
#6 LYWHL Ultra Privacy Screen Protector
If you use your S21 Ultra a lot on public transit and long commutes, you've probably met people who can't help but take a good long look at whatever you're doing on your phone. If that annoys you, the LYWHL Ultra Privacy screen protector is for you.
Once applied, you'll see a darkened screen when looking from angles, and only when you're looking straight on will you be able to view your activities. Plus, this product comes with two glass protectors for your camera module, which is a pretty cool bonus.
Making the Right Choice For S21 Ultra Screen Protection
There are many options out there if you're looking for a screen protector for your Samsung Galaxy S21 Ultra. Once you know whether you want TPU or tempered glass, privacy or clear, wet installation or dry, it becomes easier to choose. Either way you go, your display will thank you for it.
