How does the Z Fold age?
An independent reliability survey of 745 Samsung Galaxy Z Fold owners across seven generations. We measured RMA rates, screen breaks, micro cracks, screen-protector peeling and hinge flatness — and compared every generation on equal terms.
The TL;DR
Five takeaways, in one screen.
-
Fold 7
Best first-year reliability ever
Just 3.33% of Fold 7 owners have needed an RMA, only 1.67% report a broken inner screen, and zero have reported micro cracks or default-protector peeling.
-
⚠ Regression
Hinge flatness is getting worse
25% of Fold 7 owners say their screen no longer opens fully flat — up from Fold 6 (20.3%) and dramatically worse than Fold 5 (0.5%) at the same age.
-
Fold 4
The cautionary tale
The Fold 4 still posts a 47% RMA rate and 80% peeling rate — confirming the 2024 and 2025 conclusion that this is the least durable generation in the modern Fold lineup.
-
Causal chain
Peeling → cracks → break
Owners whose factory protector peeled are 8.8× more likely to experience micro cracks and 7.9× more likely to suffer a full inner-screen break.
-
Myth-busting
How you fold doesn't matter
Folding the device 5 vs 20+ times a day shows no clear effect on durability, and neither does using the inner vs the outer screen more. Age dominates.
2026 verdict: Fold 7 vs everyone else
Compared against every previous generation in their first year of ownership only, so we are comparing like-for-like.
First-year issue rate, by generation
All values are percentages of owners reporting that issue within their first 12 months. Sample sizes shown on hover.
What improved
- Inner-screen breakage in Year 1 is now 1.67% on Fold 7 — the lowest ever measured in this study.
- Micro cracks have effectively disappeared for the latest two generations (Fold 6/7) inside year one.
- Default protector peeling is 0% on Fold 7, even better than Fold 6 (1.75%) and dramatically better than Fold 4 (70%).
What got worse
- Screen-flatness regressions persist: 25% of Fold 7 owners report a hinge that doesn't open fully flat, vs 0.5% on Fold 5.
- This is the same defect class that Fold 6 introduced (20.3%) and it has not been resolved.
- Owners are vocal about it — but historically not opening flat does not correlate with screens breaking. It does correlate with future micro cracks (see Failure chain).
Per-generation snapshot
Each card shows the headline metrics for that generation's cleaned sample.
⚠ Read these numbers with the time axis in mind
These are raw lifetime rates, not age-adjusted. A Fold 7 owner has at most 10 months of use; a Fold 3 owner has up to 5 years. Issues that build up slowly — especially protector peeling, micro cracks and RMAs — are mechanically much more likely on older generations simply because more time has passed. The Fold 7's near-zero numbers here partly reflect its youth, not just better engineering.
For an apples-to-apples view, jump to the 2026 verdict or the year-by-year deep dive below — those compare each generation at the same age.
Card key — Inner / outer use: percentage of time the average owner uses the inner (large) display vs. the outer (small) display. Derived from a 1–10 self-rating. A roughly 50% / 50% split means owners use both screens about equally.
Older models (Fold 1, Fold 2) are shown for completeness but their sample sizes are too small for reliable comparison.
Year-by-year deep dive
Same metrics, broken out by Year 1, Year 2 and beyond. This is the fairest way to see whether each generation is genuinely more reliable, or simply younger.
"—" means the cohort doesn't exist yet (e.g. Fold 7 in Year 2 — the device launched in July 2025). "n<5" means the cohort exists but has fewer than 5 responses.
Why screens fail: the causal chain
The same pattern that prior studies found is even sharper in 2026's data, on a larger sample.
Default protector peels
Micro cracks appear
Inner screen breaks
Practical takeaway
If your factory protector starts peeling or bubbling, replace or remove it. The correlation with future damage is the strongest single signal in the entire dataset. We can't prove causation, but the magnitude (multiple-fold odds increase) is consistent across three years of studies.
Inner screen protector impact
Confirming the 2025 result: the factory-applied protector remains the safest option.
| Inner protector | n | Micro cracks | Inner screen broke | Any RMA |
|---|
Note: protector type and device age are confounded — owners further into ownership are more likely to have replaced or removed the original. The table shows the raw association in the cleaned 2026 data.
What does not matter
Three years of data agree on this. If anything, the 2026 numbers are even flatter.
Folds per day vs durability
Whether you fold 5 or 20+ times a day, RMA, crack and break rates barely move.
Inner vs outer screen usage
The 1–10 self-reported screen-usage axis (1 = inner only, 10 = outer only) shows no consistent trend with damage.

Methodology & filters
Why 218 of 745 responses were excluded — and what's left.
Sample sizes
- Raw responses745
- Excluded218
- Cleaned dataset527
Exclusion rules
- Factory new only. Used and refurbished devices have unknown history and age, so we can't trust their condition or ownership duration.
- Outer protector sanity check. The Fold doesn't ship with a pre-applied outer protector — anyone selecting that for the outer display is treated as a misread.
- Outer-screen self-break excluded. Outer-screen breaks "with no fault of my own" almost certainly reflect drops; we exclude these to avoid noise.
- Device-age sanity caps. A Fold 7 owner reporting 24+ months is impossible (Fold 7 launched July 2025). The same logic is applied to Fold 6 (≤ 19–24 mo) and Fold 5 (≤ 25–36 mo).
- "I don't own any of them" and the very small Z TriFold / Z Fold SE samples are excluded because we can't draw conclusions from them.
What we measured
- Generation, ownership duration and acquisition condition
- RMA / repair history
- Hinge flatness when the device is open
- Inner and outer screen breakage
- Inner / outer screen-protector type
- Default-protector peeling or bubbling, if applicable
- Visible micro cracks on the inner display
- Surface scratching of the inner display
- Self-reported inner vs outer screen use
- Folds-per-day estimate
Caveats & limitations
- This is a self-selected online survey — vocal owners with problems are likely overrepresented.
- Sample sizes for some cohorts (especially Fold 1, Fold 2, Fold 3 in early year buckets) are too small for confident inference.
- Self-reported damage labels can be ambiguous, particularly the distinction between micro cracks on the screen and scuffs on the screen protector.
- The Fold 7 cohort is still young — most reliability problems historically appear after month 12. The 2027 study will revisit this.
How this compares to 2024 and 2025
A consistent picture across three independent surveys.
2024 (n = 372 → 266 cleaned)
First study to identify the "peeling → cracks → break" chain. Fold 4 emerged as the worst generation; Fold 5 looked far better in its first year.
2025 (n = 600 → 425 cleaned)
Confirmed Fold 5 / 6 dramatic improvement. First identified the Fold 6 hinge-flatness regression (21.3% in first 6 months) and the rise of the factory-protector advantage for crack prevention.
2026 (this study, n = 745 → 527 cleaned)
Largest dataset to date and first to include the Z Fold 7. The previously identified flatness regression has carried into Fold 7. Otherwise, every other reliability metric reaches a new low for Year 1.
Conclusion
On the metrics that historically predicted Fold failures — peeling, cracks, breaks and RMAs — the Z Fold 7 is the best foldable Samsung has shipped. But the hinge-flatness regression that first appeared on the Fold 6 has carried over, and on this metric the Fold 7 is meaningfully worse than the Fold 5.
Older devices keep aging the way prior studies predicted: the Fold 4 remains the lemon of the lineup, the Fold 5 continues to age gracefully, and the Fold 3 has now firmly entered "the protector is going to peel and there's nothing you can do about it" territory.
Two things still don't matter for durability, even with three years of data and 745 owners: how often you fold, and which screen you use more. Age dominates everything.
A note on practical advice: keep the factory protector intact for as long as possible, replace it as soon as it starts to peel, and don't worry if your device folds slightly less flat than your friend's — the historical data does not link that to broken screens.
