Quick Verdict
OnePlus's FIRST foldable arrived as the best book-style foldable of 2023: 7.82-inch inner display with a meaningfully less-visible crease than Samsung's Z Fold 5, a 6.31-inch cover screen that works like a real phone (proper aspect ratio, no Galaxy-Fold ultra-narrow weirdness), Hasselblad-tuned triple cameras (48MP main + 64MP 3x telephoto + 48MP ultrawide) that outshoot the Z Fold 5 noticeably, thinner-and-lighter design at 245g (vs Z Fold 5's 253g), and 67W wired + 50W wireless charging. The catches: IPX4 only (no dust rating; Z Fold 5 is IPX8), 4 OS / 5 sec updates (short vs Samsung's same / Google's 7), no S Pen support, and the Alert Slider is missing. $1,699 launch matched the Z Fold 5's $1,799 minus $100. Buy this if you want the most refined book-style foldable hardware/cameras of 2023; skip it if water resistance, stylus support, or Samsung's deep foldable software matter most.
Pros reviewers agree on

- Best book-style foldable hardware of 2023 — thinner (5.8mm unfolded), lighter (245g) than Z Fold 5 (253g)

Cons reviewers agree on
Weaknesses flagged across multiple sources
- IPX4 water resistance only — no dust rating; Z Fold 5 has IPX8 (full water immersion)
- Only 4 OS + 5 years of security — short vs Pixel Fold's 7 years
- No S Pen support — Samsung Z Fold 5's biggest software advantage
- Alert Slider is missing from this OnePlus model (only foldable without it)

What reviewers disagree on
Points where expert verdicts diverge — weigh based on your priorities
- vs Z Fold 5 — Engadget/Verge crown the Open the best of 2023; others say Samsung's longer track record + IPX8 + S Pen still win
- Cover screen quality — Open's 20:9 ratio praised as more phone-like; some still prefer Pixel Fold's wider book-aspect
- Hinge durability — OnePlus's first foldable shows promise but lacks Samsung's 5-generation refinement

Long-term Verdict
What creators say after 30, 100, or 365 days of real-world use — the post-honeymoon reality that launch-day reviews can't cover.
Long-term reviews land on the OnePlus Open as the foldable that aged better than expected for a first-gen device — hinge holds up, cameras stay competitive, but the 4-year update commitment and IPX4 rating remain the long-term limitations.
- Hinge long-term: meaningfully less-visible crease after 1+ years of use vs Z Fold 5; OnePlus's first foldable holds up better than expected.— YouTube — OnePlus Open 1 year later
- Camera long-term: Hasselblad processing improved via updates; still leads other foldables on absolute photo quality in 2025-2026.— Engadget
- 4-year OS commitment long-term: support through 2027 — short vs Pixel Fold's 2030; OnePlus's update support is the biggest long-term concern.— The Verge
- IPX4 long-term: real-world rain/splash exposure has been fine for owners; dust ingress at the hinge remains the durability watch-item.— GSMArena
- Open Canvas multitasking long-term: continues to be praised as the best foldable software outside Samsung One UI — daily-driver feature for power users.— Engadget
- Display long-term: 2,800-nit inner+cover panels still bright and sharp in 2025-2026; no banana-curve issues.— Notebookcheck

- Long-term battery: 4,805mAh dual cell + SD 8 Gen 2 efficiency holds up; degradation similar to other 2023 flagship foldables.— Phone Arena
- Long-term verdict: the foldable owners regret least — thin, light, good cameras, solid hinge; only update window limits long-term outlook.— YouTube — OnePlus Open long-term
- Vs Galaxy Z Fold 7 ($2K+): OnePlus Open at $900-1200 used in 2026 still the value pick for book-style foldable buyers who don't need newest hardware.— YouTube — OnePlus Open 2025 review
