Samsung Galaxy Z Fold 4 Review (2026): Is It Worth Buying Refurbished in the UK?

Last updated: 26 May 2026 -- by RefurbPhone Editorial. Our UK-based engineers test every Z Fold 4 we refurbish across 30+ functional and cosmetic checks before sale.

Quick verdict: Should you buy a refurbished Samsung Galaxy Z Fold 4 in 2026?

Yes -- for the right buyer. 4 years after launch, the Samsung Galaxy Z Fold 4 delivers what it always promised -- the first Fold that genuinely felt productivity-ready with the taskbar and refined multitasking -- now at a fraction of its original GBP 1,649 RRP. Refurbished is the smart way to own this productivity Fold in 2026, especially with the newer foldable models now driving prices down across the older Samsung foldable range. This Z Fold 4 is best for buyers who want a productivity-focused foldable on the tightest possible refurbished budget.

What we like about the Samsung Galaxy Z Fold 4

After refurbishing dozens of Z Fold 4 units, here’s what consistently impresses our engineers and customers:

Snapdragon 8+ Gen 1 is still capable

By 2026 standards the 8+ Gen 1 is a generation or two behind, but for everyday browsing, messaging, video and social apps it still delivers smooth performance.

The Fold form factor genuinely replaces a tablet

The large inner display means split-screen multitasking actually works. Two browser tabs side by side, a video over a chat window, Outlook and Teams together -- this is the productivity case for a Fold, and the Z Fold 4 delivers it well.

50MP main camera takes proper photos

The 50MP main sensor with Samsung’s computational processing delivers sharp, well-exposed images that hold up against most non-Ultra Galaxy phones.

What’s not so great about the Samsung Galaxy Z Fold 4

The original RRP was hard to justify

At GBP 1,649 new, the Z Fold 4 sat in luxury smartphone territory. That’s exactly why refurbished is the right way to buy it in 2026 -- the value proposition only makes sense once the price drops.

The visible inner-display crease and the noticeable gap when closed

This isn’t a deal-breaker but it’s worth being aware of before you buy. Most owners adjust within a few weeks.

It’s heavy in the hand

At 263g, the Z Fold 4 is significantly heavier than a regular smartphone. After a few hours of one-handed use, you notice. The unfolded reading position is far more comfortable.

No dust resistance rating

The IPX8 rating covers water only, not dust. Folding mechanisms and dust are a long-term reliability concern. If you work in dusty environments, the newer IP48-rated models (Flip 6, Flip 7, Fold 6, Fold 7) are more robust.

No native Galaxy AI

Galaxy AI features that Samsung promotes today were added to newer models from 2024 onward. The Z Fold 4 doesn’t get them natively, though Samsung has back-ported some features via One UI updates.

Samsung Galaxy Z Fold 4 vs Samsung Galaxy Z Fold 5 -- what changed?

The Z Fold 5 is the successor to the Z Fold 4, launched in August 2023. Here are the main differences worth knowing if you’re weighing which to buy refurbished:

• Chip: Z Fold 4 uses the Snapdragon 8+ Gen 1 vs the Snapdragon 8 Gen 2 for Galaxy in the Z Fold 5.
• Battery: Z Fold 4 packs 4,400mAh, 25W wired vs 4,400mAh, 25W wired, 15W wireless on the Z Fold 5 (the Fold 5 also added wireless charging).
• Hinge design: The Z Fold 5 introduced the new gapless flex hinge that closes flat -- the Z Fold 4 still has the visible gap when closed.
• Weight: Z Fold 4 is 263g; Z Fold 5 dropped 10g to 253g.

Samsung Galaxy Z Fold 4 vs Galaxy Z Flip (2023) -- which form factor is right for you?

If you’re torn between a Flip and a Fold, here’s the decision in plain terms:

• Buy a Z Fold 4 if: you want a tablet-sized inner display for multitasking, productivity, S Pen note-taking and media -- think productivity power.
• Buy the Samsung Galaxy Z Flip 5 if: you want a compact, pocketable phone that folds in half -- think style, portability and one-handed use.

Both refurbished foldables save you hundreds vs buying new at RefurbPhone.

Is the refurbished Samsung Galaxy Z Fold 4 reliable in 2026?

The reliability concern foldables get tagged with is bigger than the reality. Here’s what 4 years of Samsung Galaxy Z Fold 4 units passing through our refurbishment process actually shows:

• Samsung rates fold hinges for 200,000 fold cycles -- roughly 5 to 7 years of typical daily use
• The user-replaceable inner-display screen protector can lift at the edges after 12 to 24 months of use -- we replace it during refurbishment when needed
• Battery health on returning Z Fold 4 units typically sits at 80 to 88% at the 4-year mark
• Hinge mechanism failures are uncommon in our refurbishment testing

Every refurbished Samsung Galaxy Z Fold 4 at RefurbPhone is tested across the inner display, cover display, hinge mechanism, all cameras, biometric sensors, speakers, microphone, charging and battery health. Any battery below 85% capacity is replaced before sale, and you get a 12-month UK warranty on the whole device.
