The Samsung Galaxy Z Flip 4 has been one of the most popular flip phones since it came out in 2022, and that's still the case a year on, thanks to frequent discounts. The cover screen, while not as good as the one on the newer Z Flip 5, is still useful and fun, and the software makes full use of the foldable form factor.
Keeping a phone like this looking good means using protection, and the best way to keep a Flip 4 safe is with a case. We've curated the best of the best, covering aesthetics, features, and price.

Flip and grip with the best Galaxy Z Flip 4 cases money can buy
Building cases for foldable phones isn't as simple as some manufacturers originally anticipated, but now that we're multiple generations in, cases are getting close to the same level of perfection as those made for regular phones, as are the accompanying screen protectors.
Cases for previous flip phones could have issues with wireless charging or had hinge protectors that interfered with the phone laying flat. Thankfully, those issues are all but gone, and you can use any wireless charger you like.
Spigen's Touch Armor gets our top pick. The simple, no-nonsense design looks excellent, and it keeps the Flip 4 safe without making it a brick. Add to that the fact it feels soft in the hand, and you have a winner.
Samsung's Flap Cover is the over-the-top leather case perfect for showing off your newfangled folding phone. At $90, this was our premium pick, but if you're lucky, you can get it for as little as $14 from Amazon these days, which is an absolute bargain for a case that looks and feels this good.
If you want something more practical but equally stylish, the Nano Pop is one of our favorite cases of all time. The two-tone design looks great, and the material finish is durable while nestling in the hand just fine for extended use.
What's the deal with adhesives, and what do I need to look out for?
The Flip 3 had a case issue in the USA thanks to the placement of the UWB "window." Because it was placed so near the hinge, the adhesive strip cases used to firmly attach cases to the phone would be in the same spot and could pull the window out. Models outside of North America didn't have this extra antenna. Thankfully, the Flip 4 has placed this piece of hardware elsewhere, and casemakers have learned some lessons too.
Flip 4 cases have placed the adhesive away from that 5G window, and the bond itself is better. In our experience, the adhesive can withstand a few removals from the device, and most cases come with spares in the box, just in case. When shopping for a case, remember that the more often you remove the case, the quicker those adhesive strips will fail, so if you enjoy changing cases a lot, make sure the ones you choose come with spare adhesive.
