At a glance
One-line verdict
A seriously capable foldable smartphone for full-size multitasking, provided 215g of very expensive-looking rectangle does not offend your pocket.
Best for
Buy it if you want an 8-inch screen for side-by-side multitasking without carrying a separate tablet in your bag.
Skip it if
Skip it if you need external storage, S Pen support, or a phone that does not weigh 215g in a trouser pocket.
The full picture
The Samsung Galaxy Z Fold8 Ultra 512GB exists for the person who keeps trying to do two sensible things at once on a normal phone, then ends up squinting at a spreadsheet while replying to a message and missing both. Modern life has somehow made a pocket computer insufficiently computer-like. Naturally, the answer is a phone that unfolds into an 8-inch screen.
The practical arrangement is persuasive. Closed, it has a 6.5-inch cover screen; open, it provides the larger main display and supports side-by-side multitasking. That makes it a plausible all-in-one for email, notes, maps, tickets and the administrative opera of arranging a weekend away. We think that is the Fold8 Ultra’s strongest case: it addresses a real annoyance rather than merely asking everyone to admire a hinge.
This 512GB version has 12GB of memory, a Snapdragon 8 Elite Gen 5 for Galaxy processor and a 5000mAh battery. It also supports wireless charging, USB Type-C audio connectivity and IP48 water and dust resistance. The selected Graphite UK version is listed with a 3-year warranty, which is welcome when a device has both a folding display and the social gravity of a small paving slab.
There is, as ever, paperwork. The phone weighs 215g, offers no external-storage support and does not support an S Pen. Those limits matter because the Fold8 Ultra is built around doing more on one device; the moment you want expandable files or stylus input, the tidy all-in-one fantasy acquires an asterisk. Still, for the right sort of screen-hungry organiser, it is the most complete expression of the foldable idea here.
The Irresistible
- An 8-inch main screen in a folded phone is a properly compelling answer to split-screen tasks, rather than another excuse to admire a futuristic object during a meeting.
- The 6.5-inch cover screen means the Samsung Galaxy Z Fold8 Ultra can handle quick phone jobs without every notification requiring the full origami ceremony.
- The 512GB configuration pairs substantial internal storage with 12GB of memory, which suits buyers treating one handset as camera, work device and portable distraction engine.
The Clever Part
- At 215g and 8.9mm thick when folded, it remains a single device rather than a phone-plus-tablet arrangement rattling around a bag.
- IP48 water and dust resistance, wireless charging and USB Type-C audio connectivity cover several everyday expectations without turning the specification into a scavenger hunt.
- Graphite is one of the standard colour options, and the selected UK version is listed with a 3-year warranty.
The Fine Print
- There is no external-storage support, so the 512GB capacity is the capacity you live with; digital hoarders should perform their usual solemn folder audit first.
- S Pen support is absent, which limits the appeal for anyone hoping the 8-inch screen would double as a stylus-led notebook.
- The 16GB memory figure applies to the 1TB variant, not this 512GB model; this one has 12GB of memory.
The Reality Check
- Its 215g weight and large unfolded dimensions make it a poor fit for anyone whose ideal phone disappears into a pocket and is forgotten until needed. This one is more likely to announce itself, physically and financially.
