The Samsung Galaxy Z Flip 4 is the closest we’ve seen to a mainstream foldable, thanks to its unrivaled popularity. The 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 versus the Galaxy Folds of the world, the big hit of Star Trek-fueled nostalgia, and the practicality of folding a phone into a small pocket square.

While the 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 yours 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.

Choose your best Galaxy Z Flip 4 case wisely — swapping them is expensive

Folding phone cases are expensive, lower-volume items that must be made in two parts to accommodate the hinge. We’ve always liked swapping cases for different occasions, but with the increased cost, that could be unreasonable.

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 much 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. The UAG Civilian and Otterbox Symmetry are more expensive, but they have more protection and will be of interest to those who often drop their phone.

If you want something more colorful, I wholeheartedly recommend the Caseology Nano Pop. My wife has helped me test all of these Z Flip 4 cases, and this is the one she returns to, despite being more expensive than the Tough Armor. The dual-tone purple complements the Bora Purple Z Flip 4 beautifully, and the build quality is superb. It’s comfortable and reassuring to hold and provides plenty of 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, so 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.


Q: What’s the deal with the adhesives and what do I need to look out for?

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.
