When it comes to premium flip-screen phones, it doesn’t get much better than Samsung. Renowned for its Galaxy Z Flip series, these Android-powered devices are packed with the most essential smartphone features one could ask for, on top of a cutting-edge design that puts a real emphasis on dual-screen technology. Of course, working with more than one screen means having to protect more than one panel from scratches and cracks.

Fortunately, many of the most renowned screen protector companies have gone all in, designing top-notch coverings to shield our Galaxy Z Flip. If you’re the proud owner of a Samsung Galaxy Z Flip 4, we’ve put together this list of the best screen protectors you can find for your next-level Samsung peripheral.

Which screen protectors are best for your Galaxy Z Flip 4's displays?

Your Samsung Galaxy Z Flip 4 isn’t the kind of mobile device you want to leave exposed. Covering the screens of any smartphone with some sort of protector is always a good idea, but considering the Flip 4 has more than one display for you to work with, you’ll want to be extra cautious. This is why investing in a top-shelf screen protector is going to make all the difference; and while it may seem enticing to spend as little as possible on such a simple accessory, the adage of “you get what you pay for” couldn’t be more true when it comes to mobile screen shields.

Overall, our favorite protector is the Whitestone Gen Film. It comes as a pack of three high-quality screen protectors, with one for the primary screen, another for the secondary display, and the last for the phone's hinge. If your Z Flip 4 is bare, and you want a package that lets you protect all the delicate parts of your phone, this protector is the way to go.

On the other hand, if you already have a fabulous protective film on your primary display and simply need a protector for your 1.9-inch outer screen, the Ringke tempered glass guard and the flexible bioplastic ZAGG Fusion Eco are the right choices. If your situation is the reverse, and you want a dedicated scratch-resistant film for your 6.7-inch foldable display, you'll be happy going for the Supershieldz screen protector, especially considering how cheap it is.

Now you know the screen protectors that do the most astonishing job of protecting your foldable displays. Just remember to bear in mind that to get the best results, you'll have to apply them properly. Luckily for you, we've curated a few key tips below.

Tips for applying a screen protector to your Z Flip 4's primary display

When searching for a screen guard for your Galaxy Z Flip 4's primary display, you'll find that most offerings from prominent manufacturers are rated low on Amazon, resulting from two factors. The first is the incompetence of manufacturers. For a screen protector to work well with a foldable display, it has to be specially designed to withstand the constant opening and closing of the flexible screen and its crease. So, if a manufacturer doesn't account for this while producing its screen guard, it will undoubtedly be a flop. Gratefully, all the films in our collection are void of this issue. But still, most of them have some negative reviews from users. Why is this?

That brings us to the second issue with foldable screen protectors: users often apply the protector incorrectly. When installing a protective film on your Galaxy Z Flip 4, you must exercise the utmost caution to avoid ending up with unsightly bubbles or having the protector peel off after a few days. Make sure you follow the manufacturer's guidelines closely during the process, or you can opt for a professional to assist you with this delicate procedure.

All screen protectors vary, and the same goes for their application process. As a rule of thumb, leave your phone alone (don't use or close it) for about half an hour after applying the protector for its adhesive to set properly. This reduces most of the issues encountered with high-quality Z Flip 4 screen shields.

Are there any tempered glass shields for the Z Flip 4's primary screen?

It's no new discovery that tempered glass guards offer superior protection against scratches and cracks, above all other types of screen protectors. Given this, one would expect them to be the most suitable protectors for the Z Flip 4's fragile and tender foldable display. While this is theoretically true, it's impractical in reality due to tempered glass's rigid and non-flexible nature. In essence, using one on your Z Flip 4's main display will mean saying goodbye to the phone's folding ability — and that, of course, defeats the whole point of the phone.

Although there's a two-piece tempered glass protector available for the Flip 4's primary screen, it is unusable for the most part. It leaves a huge gap in the middle of the screen for the phone's hinge to function, plus the space leaves the center portion of your display exposed and vulnerable to damage, while also making simple actions like swiping across your display a pain.
