We pay up to £85, paid the same day.
The offer mendmyi makes for a Galaxy S20 5G is set by the condition you report, so mention any cracked screen or worn battery from the start. We buy this phone in any condition, meaning those faults change the offer rather than ending the sale. Once mendmyi inspects the device and confirms the offer, that quote is held for 14 days.

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 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 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 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 5G is worth depends on
Storage
Bigger storage means a better price. Tell the finder above which Galaxy S20 5G you have and it prices that exact variant.
mendmyi buys this Galaxy S20 5G in its 128GB storage size only. Check the capacity in your phone's settings before asking for a quote, because the offer applies to that storage option.
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 cracked screen on your Galaxy S20 5G does not need fixing before you contact us. Select the condition that matches the damage when you request a quote, and the offer mendmyi gives is built from what you describe.
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.
Once your Galaxy S20 5G has been inspected and the offer confirmed, that quote is held for 14 days. You can use that window to arrange the sale without the offer changing.
Free collection is available for the Galaxy S20 5G, and you can also use the Haverhill shop counter or post the handset. The offer mendmyi confirms after inspection is the same no matter which route gets the phone to us.
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 5G in front of us.
Take a worn battery into account when describing your Galaxy S20 5G. If the charge no longer lasts as it once did, include that in the condition you select; a worn battery does not stop the purchase, it just needs to be reported.
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 5G once it is signed out of your Google account, which is what clears Factory Reset Protection.
If your Galaxy S20 5G is still signed in to a Google account, sign out and clear any screen lock, PIN, password or biometrics before sending it. Doing so switches off Factory Reset Protection and stops the phone from remaining tied to your account.
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 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 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 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.
What Our Customers Say

“I needed a Windows 11 reinstall quickly, no worries, would definitely recommend ”
“Took my daughter’s iPhone 11 in due to needing a new screen. Very helpful and friendly. All done within the day and kept informed with the repair. ”
“I’m genuinely impressed with the service I received. My phone suffered water damage and completely stopped displaying anything, so I thought my data was gone for good. Thankfully, the team managed to recover everything — photos, contacts, messages, the lot. They were professional, quick, and kept me updated throughout the process. What felt like a disaster turned into a huge relief thanks to their skill and care. If you’re dealing with a water‑damaged device and worried about your data, I can honestly say you’re in safe hands here. Highly recommended.”
“Really good service and very quick when fixing my iPad screen”
“They fixed my phone right away, thank you”
“Fantastic service”
“Popped in to see if worth fixing my mobile. Was very helpful in weighing up if it was worth it or not. As it wasn’t, I just enquired if he had a phone I was looking for. Turned out although they wouldn’t normally of had one, as new out. He did as someone else wanted to change to a larger version. So with in a few hours I had a new phone, which saved me £200 and stopped me wasting any further money on my old phone. Very helpful and informative. Switched cable for one suitable for my set up and put a screen cover on for me at no charge. Wouldn’t hesitate to use again.”
Selling your Galaxy S20 5G
Should I repair my Galaxy S20 5G rather than selling it to you?
That depends on whether you want to keep the Galaxy S20 5G, because mendmyi repairs devices as well as buying them and is not steering you to either route. If you want a working phone to carry on with, repair is the relevant option; if you are ready to let the handset go, selling is the relevant one.
How long is a confirmed quote for my Galaxy S20 5G held?
Once mendmyi inspects the Galaxy S20 5G and confirms the offer, that quote is held for 14 days. You can use those 14 days to arrange the sale, with no change to the offer.
Will the quote for my Galaxy S20 5G be lowered when it arrives with you?
No, mendmyi does not negotiate the quote down when your Galaxy S20 5G arrives. The offer you saw is what the purchase is based on, provided the device is as you described when you asked.
Will you take my Galaxy S20 5G if both the screen is cracked and the battery is worn?
Yes, we buy a Galaxy S20 5G with both a cracked screen and a worn battery. Choose a condition that covers the two faults when you ask for a quote, so the confirmed offer reflects what we will actually receive.
Which account and lock details do I need to remove from my Galaxy S20 5G before selling?
Remove your Google account sign-in and clear any screen lock, PIN, password or biometrics before sending the phone. Doing so switches off Factory Reset Protection and means the Galaxy S20 5G is no longer linked to your account when we handle it.
If I post my Galaxy S20 5G rather than bringing it to Haverhill, is the offer the same?
Yes, all three routes give the same confirmed offer for the Galaxy S20 5G: posting it in, booking a free collection or handing it over at the Haverhill shop counter. Choose whichever is easiest; the offer does not depend on how the phone reaches us.
