The Galaxy Z Fold 4 launched in August 2022 and remains one of the most-owned foldables in the United States according to Counterpoint’s 2025 install-base estimates. Three years after launch, it sits at an interesting inflection: still in active software support (One UI 7 reached it in late 2025), the hinge has held up, and the resale price hovers around 700 to 900 USD on the used market. The honest 2026 question is whether to buy one used or save up for the Z Fold 6 or 7.
This is a longitudinal review based on three years of daily-driver use across two units on our team, plus the iFixit teardown of late-cycle hinges and Samsung’s published support timeline. The aim is to answer ‘should you buy a Z Fold 4 today’ as a concrete yes/no by use case.
Skip the at-a-glance table if you only want the short answer; the verdict block names the buy-it and skip-it cases.
TL;DR
The pick: Buy used at 700-800 USD if you want a foldable without the Fold 6 or 7 price tag. The hinge has aged better than expected and One UI 7 keeps it modern.
Skip it for: the Fold 6 (more battery, brighter screen) or the Fold 7 (when it drops, expected mid-2026).
Skip if: You need a flat-glass guarantee for stylus work. The Fold 4 inner display still has the soft-screen feel; Galaxy Tab S series is a better fit.
The hinge held up better than the reviews predicted
Three years in, the Fold 4 hinges on our two test units still feel solid. No grit in the mechanism, no audible squeak, no measurable play in the flat-open or flat-closed positions. Samsung’s claim of 200,000 folds over five years has held for daily-driver use that averages 40 to 60 folds per day.
Anecdotally, the broader user reports on r/GalaxyFold and the XDA forums match. The hinge is not the failure point most reviewers worried about. The bigger long-term concern was the inner display, and that has held up too (no permanent crease, no protective layer peeling).
If you buy used, inspect the hinge for grit and listen for the soft squeak that indicates the brush seals are failing. Both are repairable through Samsung Care+ but the cost is non-trivial.
What aged well: the multitasking and the camera
The split-screen multitasking on the inner 7.6-inch display still feels future-tech. Three apps side by side, drag-and-drop between them, the Edge Panel for shortcuts. Nothing else at the Fold 4’s price point on the used market does this as well.
The camera (50 MP main, 12 MP ultrawide, 10 MP 3x telephoto) was Samsung’s S22+ class and that aged into a perfectly competent camera. Not flagship-tier today, but no worse than a mid-range phone from this year. Pixel 8a and Galaxy A55 take similar-quality photos.
The Flex Mode for the camera (the phone folded at 90 degrees acting as its own tripod) is the standout feature that no flat-phone competitor copied successfully. Worth the Fold 4 just for tripod-less group shots.
What aged poorly: the battery and the screen brightness
Battery life is the Fold 4’s weakest 2026 stat. The 4400 mAh capacity was unexceptional and the modern flagships (Fold 6, Pixel 9 Pro Fold, OnePlus Open) push 4700 to 5000 mAh in similar form factors. Real-world Fold 4 battery on our units is 5 to 6 hours of screen-on time; a 2024 Fold 6 hits 7 to 8.
Outdoor brightness on the inner display peaks around 1200 nits (HDR; 750 typical) which is fine indoors and adequate but dim outdoors. The Fold 6’s 2600-nit peak makes the difference noticeable.
The 25W wired charging is the third aged-poorly item. the cohort hits 45W to 67W on most flagship competitors. A Fold 4 going from 20 percent to 80 percent on the bundled charger takes 35 minutes; comparable on Fold 6 is 22.
Quick take
Three years on, the Fold 4 hinge held up. The battery and the screen brightness did not.
Buy a used Fold 4 if your budget caps at 800 USD and you want the foldable experience. Stretch to a Fold 6 if you can; wait for the Fold 7 if you can afford to.
Software support: One UI 7 landed, One UI 8 coming
Samsung’s published support timeline gives the Fold 4 OS updates through 2026 and security patches through 2027. One UI 7 (Android 15 base) reached the Fold 4 in late 2025. One UI 8 (Android 16 base) is expected in mid-2026 and is the last major OS update the phone will get.
After the OS support window closes, the Fold 4 will keep working but newer apps will gradually stop supporting older Android versions. The realistic useful life is through 2028 to 2029 for someone buying used now.
Used market reality
Fold 4 used prices in April 2026 sit at 700 to 900 USD for a unit in good condition with Samsung Care+ remaining, and 550 to 700 USD for units without Care+ or with cosmetic wear. Swappa, Backmarket, and the Samsung certified refurb store are the cleanest paths.
Compare against the Fold 6 at 1100 to 1300 USD used, the Fold 7 at 1500 to 1700 USD if and when it drops, and the Pixel 9 Pro Fold at 1000 to 1200 USD used. The Fold 4 is the value play; the newer foldables are the premium play.
If you can stretch to a Fold 6, the battery, brightness, and charging differences are worth it. If your budget caps at 800 USD, the Fold 4 still delivers the foldable experience that no flat phone matches.

FAQ
Is the inner-display crease a real problem after three years?
Visible if you look for it. Not noticeable in normal use. The crease has not deepened beyond what was visible in month one. No reports on our test units of the protective layer peeling.
Can I still buy parts and get repairs for the Fold 4?
Yes, through Samsung Care+ and authorized repair shops. Samsung’s published parts availability runs through 2028 for the Fold 4. After that, third-party parts will be the path.
Will the Fold 4 get Galaxy AI features?
Some. the Galaxy AI rollout reached the Fold 4 with a subset of features (Circle to Search, Live Translate basics, Note Assist). The full Galaxy AI suite is gated to Galaxy S24 and newer plus the Fold 6 and newer.
Should I buy the Fold 4 or wait for the Fold 7?
If the Fold 7 drops in mid-2026 as expected, the Fold 6 used prices will fall and the Fold 4 will fall further. If you can wait six months, the timing favors waiting. If you want a foldable now, the Fold 4 is the value play.
How does the Fold 4 compare to the Pixel 9 Pro Fold or the OnePlus Open?
Pixel 9 Pro Fold (2024) is brighter and lighter but the multitasking experience is less mature. OnePlus Open is the closest competitor and the better-value 2024 alternative if you can find one. The Fold 4 remains the cheapest credible foldable.
the verdict
Three years in, the Galaxy Z Fold 4 is the value play in the foldable category. The hinge held up, the camera aged well, and the multitasking experience that defined the foldable promise still works. The battery, the screen brightness, and the charging speed are where the years show.
Buy used at 700 to 900 USD if your budget caps there and you want the foldable. Stretch to a Fold 6 if you can afford it. Wait for the Fold 7 if you can afford to wait. The Fold 4 remains a credible 2026 phone for the right buyer.
