We pay up to £151, paid the same day.
Your Galaxy S20 Ultra 5G's value is driven by condition, so a cracked screen, worn battery or other damage simply moves it to a different condition tier, and the quote still stands. Once we inspect the handset and confirm the offer, that amount is held for 14 days. The quote shown to you is the amount we pay, not an opening position, and it is not reduced on arrival.

Once we send your offer it will not drop, so you have time to decide.
We repair, so faulty still pays
Cracked screen or worn battery is a job on our bench, not a write-off.
Not the Galaxy S20 Ultra 5G storage or condition you were looking for?
We buy a lot more than we list here. Older iPhones, Samsung and Pixel handsets, iPads, Apple Watches, MacBooks and games consoles all get a real offer, and a cracked or faulty device is still worth something to us because we repair them in house. Tell us what you have and we will come back with a firm price.
No obligation, and nothing to pay. We will not give you a number we cannot honour, so if we need to see it first we will say so.
Three steps
How selling your Galaxy S20 Ultra 5G works
No haggling, no waiting on a callback, and no offer that quietly drops when you arrive.
Get your price
Pick your Galaxy S20 Ultra 5G storage and condition above and the price we pay appears straight away, no waiting for a callback.
Get it to us, three ways
Walk into the shop, book a free collection from your door within 5 miles, or post it free from anywhere in mainland UK.
Paid the same day
Accept the offer and you are paid there and then, by bank transfer, or store credit towards an upgrade or downgrade.
Your price
What your Galaxy S20 Ultra 5G is worth depends on
Storage
Bigger storage means a better price. Tell the finder above which Galaxy S20 Ultra 5G you have and it prices that exact variant.
We buy the 128GB, 256GB and 512GB versions of the Galaxy S20 Ultra 5G. Before you request a quote, check the capacity in Settings and pick the matching option, so the storage we inspect is the storage you were quoted for.
Screen condition
A cracked screen does not drop you to a faulty price. You keep the condition the phone is otherwise in and we simply take off what the glass costs us to replace, because we replace them ourselves.
A crack or other visible damage does not make your Galaxy S20 Ultra 5G impossible to sell. When you request a quote, choose a condition option that matches the damage, and the offer you receive already reflects that level of wear, so nothing changes when the phone reaches us.
Body and connector
Dents, scuffs and cracks to the casing are graded as part of the overall condition. A cracked back or a bent frame lowers the offer but rarely rules a device out.
You do not have to post the phone. A free collection can be booked, you can bring it to our Haverhill counter, or you can post it in, and the route you choose makes no difference to the figure quoted.
Once your Galaxy S20 Ultra 5G has been inspected and the offer is confirmed, the figure is held for 14 days. That gives you room to decide whether to complete the sale without the amount being re-quoted in the meantime.
Battery health
We check battery condition ourselves on the bench rather than asking you to self-report a figure online, since there is no single on-device reading we can rely on for every brand. A genuinely worn cell comes off at what a real replacement costs us, worked out once we have the Galaxy S20 Ultra 5G in front of us.
The Galaxy S20 Ultra 5G has a 5000 mAh battery, and its health is assessed as part of the overall condition. A battery that has worn down is a condition choice rather than a deal-breaker, so include it in your description and the quote accounts for it.
Whether it powers on
A device that boots and passes our checks is worth more than one that does not, but a dead handset is still worth telling us about rather than binning.
iCloud or Google account lock
We can only buy your Galaxy S20 Ultra 5G once it is signed out of your Google account, which is what clears Factory Reset Protection.
Before you send your Galaxy S20 Ultra 5G, remove your Google account and remove any screen lock, including a PIN, password or biometric unlock. If it arrives still linked to your account, we cannot prepare the device for its next owner until the account is cleared, and payment is delayed while that is sorted out.
Original parts matter to the price: an aftermarket screen, battery or camera fitted by someone else changes what we can pay. If you are not sure what is in your Galaxy S20 Ultra 5G, our guide on how to check a refurbished phone walks through what to look for.
Five minutes
Before you sell: five minutes that protect you
Do these before you hand the device over and the sale goes through without a hitch.
-
1.Back up what you want to keep
Photos, contacts and anything else you would not want to lose. If an upgrade is replacing it, here is our guide to moving everything to your new phone.
-
2.Sign out of iCloud or your Google account
Turn off Find My before you hand over the Galaxy S20 Ultra 5G. A device still signed in cannot be bought from you.
-
3.Take out the SIM and any memory card
These are yours to keep and are not part of the sale.
-
4.Note down the IMEI
Dial *#06# or check Settings to find it, in case you want a record for your own files.

No surprises
Ownership, ID and your data
Three things worth knowing before you sell anything to anyone, not just to us.
The device has to be yours to sell
We cannot buy a device that is still under contract or on finance, because until it is paid off you are not yet its legal owner. We also cannot buy a device that is part of an ongoing insurance claim, or that has been reported lost or stolen.
"This device is not under contract or finance, is not part of an insurance claim, and has not been reported lost or stolen - I own it outright."
We record name, address and ID on every purchase
We record the name and address of everyone we buy from, and check them against photo ID and proof of address. HMRC requires it: buying from a private seller, we have to raise the purchase invoice ourselves and it must carry your details. Bring the documents into the shop and show us, or send a photo if the device is reaching us another way.
It protects you as much as us: the purchase can always be traced back to a genuine sale rather than an anonymous one. A photocard driving licence showing your current address covers both documents on its own.
GOV.UK: VAT margin schemes, section 6.2Your data is wiped at our shop
Once your device is checked in, it is fully wiped and factory reset at our shop before it goes anywhere else. Nothing of yours is left behind on it.
Locked in
Your price is held for 14 days
Once we send you an offer for your Galaxy S20 Ultra 5G, it is held for 14 days. That gives you time to compare us against the online recyclers before deciding, without the price moving under you.

Selling your Galaxy S20 Ultra 5G
Can mendmyi collect my Galaxy S20 Ultra 5G from my address, or do I have to arrange postage myself?
Yes, we can collect it from your address free of charge. If you prefer, you can also drop the phone at our Haverhill counter or post it in yourself, and the quote is identical for all three routes.
When I sell my Galaxy S20 Ultra 5G, is photo ID a requirement and how quickly do you pay after I send it?
Photo ID and proof of address are required on every purchase, with no exceptions. Once those have been confirmed, payment goes out the same day, whether the phone was collected, dropped off or posted to us.
My Galaxy S20 Ultra 5G has a cracked screen. Would I be better off repairing it before selling it, or is selling it damaged the sensible option?
There is no single sensible option, and mendmyi repairs devices as well as buying them, so this is a genuine choice rather than a sales pitch for one service. What is best for you depends on the rest of the phone's condition and what happens after the crack is fixed, so we would not recommend one route blindly.
How long is the offer for my Galaxy S20 Ultra 5G valid after you have checked the phone over?
The figure is held for 14 days once we confirm the offer after inspection. You have that full window to decide whether to go ahead without the amount changing.
When my Galaxy S20 Ultra 5G arrives, will your team try to negotiate a lower quote than the one I was shown?
No, the quote you were shown is the amount we pay once the phone's condition matches what you selected. It is not an opening position and it is not negotiated down on arrival.
I have a Galaxy S20 Ultra 5G with a cracked screen and a worn battery - would you still buy it in that state?
Yes, we would still buy it. A cracked screen and a worn battery are both condition choices, so select the option that reflects them and the quote you receive already accounts for the two faults together.
