How much is my Samsung Galaxy S25 Ultra worth?
One generation back from the newest Ultra, the S25 Ultra is among the most requested used Android phones in the UK. Buyers specifically look for it, so clean examples with the S Pen present move fast. Screen burn-in is the fault we check for most on Ultras of this age.
- Storage tier (256GB, 512GB or 1TB)
- AMOLED burn-in after a year or more of use
- S Pen present and working
- Battery condition and charging behaviour
Does Galaxy S25 Ultra storage affect its value?
We buy the Galaxy S25 Ultra in 256GB, 512GB and 1TB. Higher capacities are harder to source second-hand and are valued above the entry 256GB handset in the same condition.
Can I sell a damaged Galaxy S25 Ultra?
Yes. Cracked AMOLED panels, damaged rear glass, camera faults and battery issues are all bought on this model, and parts availability is good — which usually means a better offer than on a brand-new flagship with the same damage.
Can I sell a network-locked Galaxy S25 Ultra?
A network lock is not a problem — carrier-locked handsets are still bought, and UK networks unlock free of charge on request. An account lock is different: the device must be signed out of the previous owner's Samsung and Google accounts, with Factory Reset Protection cleared through official methods. We never bypass security and we do not buy devices reported lost or stolen. Phone locks explained.
Where can I sell my Galaxy S25 Ultra?
Post it to us from anywhere in the UK, or sell it in person at 41 Church Street, St Helens, WA10 1AX or 48 Lowther Street, Carlisle, CA3 8DP. Both counters are open Mon–Sat 9:30am–5:30pm · Sun 10:00am–4:00pm. Bring valid photo ID — it is required for every second-hand purchase.
Every valuation is confirmed after we have inspected and tested the handset. We never quote a final price sight unseen, and you are free to walk away at any point.
