Best Samsung Galaxy Z Flip 4 cases in 2023

While the Flip 4 is quite compact, it's still expensive and delicate, so give it the best case you can

The Samsung Galaxy Z Flip 4 is the closest we've seen to a mainstream foldable, thanks to its unrivaled popularity. The Galaxy Z Flip 4 kept the strengths of the Z Flip 3 and fixed the vast majority of its weaknesses, especially in the battery department. Flip foldables are becoming popular due to their relatively lower price than the Galaxy Folds of the world, the big hit of Star Trek-fueled nostalgia, and the ability to fold a phone into a small pocket square.

Although the Galaxy Flip 4 features water resistance, armor aluminum, and Gorilla Glass Victus, it's not indestructible; all metal and glass phones are fragile, whether they fold in half or not. So to keep your Z Flip 4 safe, you'll want to protect it with one of the best screen protectors and a solid case. We've gathered the best of the best to help you pick the perfect case.

While hinge protection last year meant dealing with unsightly flaps or bumps, the Spigen Tough Armor protects the hinge while still unfolding flat on a table. Its multi-layer construction allows for robust protection, while raised edges around the inner and outer screens should help you avoid damaging that precious, perilous folding display. Spigen also confirmed to Android Police that it repositioned the adhesives to keep it secured to your Flip 4 without damaging anything.

This Galaxy Z Flip 4 case may seem gaudy and flashy, like a ridiculously expensive handbag circa 2002, but in person, it's perfectly over the top. The sliding cover for the hinge has so far stayed pressed against the back of the top of the case rather than flopping around, and it isn't as chunky as these images might make it look, though it is far from thin.

The Nano Pop series is well-known for its subtle grip, iconic look, and slim, air-cushioned protection. The Light Violet colorway of the Nano Pop, in particular, is quite possibly the most stylish Galaxy Z Flip 4 case around. Bold Pantone purple and periwinkle accents complete the Bora Purple's spectrum, though the case also looks quite fetching with the Blue and Graphite models. This case doesn't guard the hinge, but you get a nice edge around the cover screen and cameras.

The UB Pro claims 20-foot drop protection. And when the case is in your hand, you will absolutely believe that from its super-solid feel. However, I wish this included a sliding bumper cover like others on this list. After all, this is a heavy-duty Galaxy Z Flip 4 case that leaves one edge completely naked when the phone is closed, but that's what the holster is for. Indeed, this is the only case belt clip I've been tempted to use in years.

While 5-foot drop protection may not seem stellar next to i-Blason and Supcase, it is for cases as unique and eye-catching as the Casetify Impact Series. And because it's made from over 60% recycled material, you can mix and match four base case colors with well over 200 designs to find the perfect look for your Z Flip 4. The case comes with eight optional adhesive strips; however, they're optional, as the case fits rather well even without them.

The Civilian Series by Urban Armor Gear may not have the multi-material majesty of the Monarch, but it's durable as all get out. The honeycomb hollows inside this case add air cushioning for impact resistance without adding weight. Higher bumpers around the camera and cover screen add extra peace of mind, while a thin, flexible cover covers the hinge when the case is closed.

VRS Design is best known for its ruggedly handsome wallet cases, but the durability alone makes the QuickStand series worth your time and money. The hinge cover here isn't as durable as its beefier Terra Guard cousin, but it has a sturdy kickstand inside. While kickstand cases might not seem as useful when we have Flex mode, they allow you to prop your Galaxy Z Flip 4 up at more angles.

This ultra-slim Galaxy Z Flip 4 case won't offer impact protection, but it also won't obscure or detract from the natural beauty of your illustrious flip phone. While clear polycarbonate cases can sometimes get those rainbow, oil-slick-looking puddles on the back where the phone and plastic come together, the Ringke Slim uses a dot matrix inner finish to prevent those unsightly blemishes and keep everything beautifully slim.

In partnership with i-Blason

i-Blason knows that just because a case is cute doesn't mean it can't be tough, and the i-Blason Cosmo Series brings style and 10-foot drop protection to its Galaxy Z Flip 4 cases. This is not the two-layer style with the hard plastic frame — that would be too bulky for the compact coolness of the Flip 4. Instead, thanks to the clear side bumpers, the Cosmo compliments your flip phone's particular colorway rather than covering it up.

OtterBox has long cemented itself as the Kleenex of heavy-duty device protection. For the Flip 4's Symmetry Series Flex, OtterBox has a sliding hinge cover that hides inside the front and back panels when open, allowing you the best of both worlds so long as you're willing to put up with a slightly thicker case. The hinge cover sports a rather fetching pattern of waves across it, adding some vibrance to an otherwise relatively plain single-color case.

With such a compact profile, it's no real surprise that wallet cases have some significant challenges for the Galaxy Z Flip 4. Goospery makes a few different styles, and this particular Wallet Ring Case lacks the pain points of its competitors. To avoid interference from the ring strap, you simply slide the card in from the side rather than a card slot at the top of the hinge.

There's a reason Samsung chose to include this case with Samsung Galaxy Z Flip 4 preorders: its ring case is simple, adorable, and comes in many colors. Unfortunately, Samsung's silicone cases are known for being particularly strong dust magnets, even among silicone cases, but this one seems to have avoided this curse. We're not entirely sure what blood magic ritual that entailed, but it can still be hard to retrieve from a pocket, although the ring helps.

Due to selling in lower volumes than more mainstream phones, foldable cases tend to be more expensive. We like to swap cases around for different occasions, but with the increased cost, that isn't as reasonable.

A lot of these cases use adhesive strips to hold onto the phone, and removing them can damage them. (That isn't always the situation if you're careful, though.) Spigen also includes replacement strips in the box and sells them on Amazon. Even so, removing the case for cleaning is more difficult than usual. With that in mind, pick a case wisely to ensure you'll be happy using it long-term.

Spigen has put a lot of effort into the Flip 4 cases, especially focusing on customer feedback. The retooled cases grip the phone better and use less adhesive, and the pads there are more durable. That's why Tough Armor is our best overall pick. While we wish it came in more color options, the build quality is fantastic, as it nestles into the hand nicely and keeps the Flip 4 safe from harm. If you want something more colorful while maintaining the same levels of protection, the Caseology Nano Pop is an excellent choice. My wife uses a Flip 4 as her daily phone, and she helped me test all of these cases. She always returns to the Caseology Nano Pop. It's comfortable, keeps the phone safe, and nicely complements her Bora Purple Flip 4.

The i-Blason Cosmo is another fantastic choice for those wanting a fancy design, thanks to the unique gemstone-inspired patterns and colors. It's thicker than the Caseology and not quite as comfy, but it makes up for that with striking looks and slightly better drop protection.

First-party accessories are a must for some, and thankfully Samsung's cases are great, even if a little pricey. The Leather Flap Cover offers robust hinge protection, so it does a decent job keeping the Flip safe despite being so thin. Samsung's faux leather is always excellent, and this case feels more premium than any other.

Samsung's other offering is the Silicone Cover With Ring (catchy name). It has a similar thickness to the Leather Flap Cover, swapping the materials and changing the hinge cover for a metal ring. Looping a finger through the ring feels comfortable and makes drops less likely. Being first-party accessories, both of these cases come in colors that complement the available finishes for the Z Flip 4.

All the cases in this list claim to use fast charging with Samsung-compatible wireless chargers — though, keep in mind wireless charging speeds and consistency vary from phone to phone and from case to case. Also, the distance between the charger's coils and the phone's coils will impact speed and efficiency, so some cases might get in the way, even if they don't prevent fast wireless charging from working entirely.

Last year, the "windows" on the frame of the Flip 3 that allowed for better UWB connectivity were placed right near the hinge, which was also where most case manufacturers put the adhesive strips that kept said cases in place. In some instances, if the adhesive was too strong — or if the phone had already been slightly damaged from a drop — the cases would sometimes rip the UWB panels off the frame of the Flip 3, ruining the phone and sending you running for a repair center.

Samsung changed the frame's design to prevent these catastrophic confluences from recurring in the Flip 4, but that wasn't the only adhesive fail accessory manufacturers had to learn from last year. Some cases didn't have enough adhesive — or strong enough adhesive — which led to cases just sliding off the phone when you pulled on it. It didn't help that most case makers put this adhesive along the sides of the phone rather than across the front panel or back panel, leading to more chances of the adhesive coming unstuck due to the smaller surface area.

This year, many manufacturers have retooled their case designs and the adhesives they use to keep your case safely secured to your Flip 4. When looking at cases, always double-check the renders to see where the adhesive strips are placed and if it comes with spares. After all, you might not be taking your case off that often, but you'll still have to do it whenever you need access to the SIM tray should you change carriers — or change between phones — on a semi-regular basis.
