Amazing Value for a Powerhouse Phone!
I recently bought a refurbished Samsung Galaxy S21 Ultra Phantom Black (512GB, 16GB RAM, Unlocked) and I’m honestly blown away by the value for the price I paid. You wouldn’t even know it’s refurbished – it looks and works like new! Performance: With 16GB of RAM, this phone is incredibly fast. Apps open instantly, multitasking is smooth, and it handles everything from streaming to gaming with ease. Storage: 512GB is more than enough for all my apps, photos, and videos. I don’t have to constantly delete things or rely on cloud storage. Condition: For a refurbished device, the condition is excellent. There may be a tiny mark or two if you look closely, but it feels solid, clean, and well cared for. Display & Camera: The screen is stunning – bright, sharp, and super responsive. The camera quality is incredible, especially the zoom and night mode. Perfect for capturing high-quality photos and videos. Battery & Unlock: Battery life is very good, and being unlocked means I can use it with any carrier, which is super convenient. If you're on a budget but still want a top-tier smartphone, this refurbished S21 Ultra is a smart choice. High-end specs, huge storage, and beautiful design – all for a fraction of the price. Couldn’t be happier with my purchase! Thank you

Samsung S21 Ultra Refurbished (excellent condition)
I was a bit dubious buying a refurbished phone having read previous reviews but must say I am delighted with this purchase. I bought this phone in Nov so have had 2 months now and no issues at all. Phone operates well, fast processing and battery life is excellent (much better than my old S9+). The camara quality is also much more superior. The phone came well packaged and included a USB cable and sim pin. The condition of the phone is as advertised in excellent condition with only a couple of very minor scrapes on top corner but this is not noticeable unless you go looking. Screen was perfect with no scratches at all. Overall delighted with this purchase from 4gadgets and have recently bought a S21 for my wife which was also in great condition and working perfectly. Thanks

Avoid
I bought 2 of these phones just over a year ago and the problems started straight away. camera fail error. screens erratic when charger plugged in, terrible signal, loses 40% battery overnight on both phones. and replacement. the list goes on. eventually had to return for replacement. i should have asked for a refund at that time, however customer services offered replacement so accepted. a short time later the camera failed again. reset phone, still nothing. after further investigation i think these telephones are imported from USA and have the screens or back replaced then resold with uk software although original Verizon contract phones. having since had the phones looked at properly it is noted that neither screen had been sealed properly which allows dust to enter, this can now be seen on the inside of the front facing lens so that camera is useless. all i can say is AVOID.

Excellent Condition
Got the phone delivered quick on a Tuesday, way ahead of the quoted weekend. Very satisfied with delivery. It came in a plain black box with USB-C cable (no charger). Phone condition is excellent. Like brand new. Very impressed with condition. For the cost of a brand new mid range phone, this is a flagship with 256GB from a couple years back. Everything works as expected. The ONLY downside to this phone is that the battery condition is around the 85% mark (to be expected for 3yr old phone) and the phone is already a powerhouse of functionality and so is heavy on the battery. Still with my normal regular use a day an a half is doable. or 1 day heavy use. Very clear screen display and capability and if you can think of it, this phone can do it. Of course the main reason for getting this phone was the camera. It does not disappoint. The zoom capability is incredible. Clear photos up to 30x magnification and reasonable clarity up to 100x. Excellent video recorder too with 4K 60fps on all cameras front and back. A weakness in the video is low light but that can be improved significantly by switching down to 30fps and then using something like Davinci Resolve to interpolate back to 60fps. All in all, well worth the money.....

Great Bargain 👍
I ordered the device early hours Tuesday 13th May and was to arrive next day 14th, unfortunately no fault of 4gadets it didn't arrive until 15th but this wasn't a massive issue for me as I had a device to see me through. When the device arrived it was well wrapped even came in a box, I took it out to inspect it, also gave me a wire to charge the device. There's no faults, no scratches or bumps it was like a brand new phone, both cameras work no visual problems, no problem with volume speakers work fine, and no problem with charging the device, I've managed to download all my stuff to the device and still have plenty space for more, very glad I bought it was actually shocked with it as I wasn't expecting it to be that great being second hand, well I was wrong! It looks and feels like a brand new phone, I'm happy with my purchase and will be using again for more devices, no complaints from me, thank you 4Gadgets

Not excellent condition
Stated as, excellent condition, this was not the case with this phone as it had clearly been dropped. It was dinted on the corner also probably had a new screen as you could see where they had damaged the edge trying to do this. Taking in all the above I would definitely say this phone was not in excellent condition it also had no charger in the box which was stated on purchase. With all the above being a problem to me Amazon recommended that I return the item for a full refund but 4gadgets expected me to pay for the return of the phone even though it was their fault it had to be returned which was not cheap. I purchased the same phone from another shop on ebay which was £60 cheaper and this one WAS in excellent condition. The phone itself is a fantastic phone and after a lot of research decided on this model because of good reviews and I can honestly say that all the reviews were right it has lots of features and well worth the money. I would recommend this model of phone to anyone and Amazon was very helpful through all of this and made the return process very easy.

Top-Smartphone mit brillanter Kamera, starkem Display und Premium-Verarbeitung
Ich nutze das Samsung Galaxy S21 Ultra nun seit einigen Wochen als Hauptgerät und bin beeindruckt, wie durchdacht und leistungsstark es ist. Schon beim Auspacken merkt man, dass hier Premium-Qualität steckt: edles, mattes Glas auf der Rückseite, massives Aluminiumgehäuse und ein beeindruckend scharfes Display. Der 6,8-Zoll-Bildschirm ist eines der Highlights – extrem hell, gestochen scharf und mit 120 Hz butterweich beim Scrollen. Farben wirken lebendig, aber nicht übertrieben. Besonders angenehm: Das adaptive Refresh-Rate-System spart spürbar Akku im Alltag. Die Kamera gehört zu den besten, die ich bisher genutzt habe. Der Zoom ist dank der beiden Teleobjektive (3× und 10× optisch) erstaunlich stabil und detailreich. Auch bei wenig Licht liefert die Hauptkamera natürliche, rauschfreie Bilder. Der Autofokus ist schnell und zuverlässig, Videos wirken professionell. Leistung und Akkulaufzeit sind auf sehr hohem Niveau. Selbst bei intensiver Nutzung (Navigation, Social Media, Kamera, Streaming) komme ich problemlos durch den Tag. Laden geht schnell – auch wenn Samsung kein Netzteil mehr beilegt, funktioniert jedes Power Delivery Ladegerät einwandfrei. Kleine Kritikpunkte: Das Gerät ist recht groß und schwer, was Einhandbedienung erschwert. Außerdem wird es bei längerer Kamera- oder Spiele-Nutzung leicht warm. Trotzdem überwiegen klar die positiven Seiten. Fazit: Ein echtes Spitzen-Smartphone mit exzellenter Kamera, tollem Display und starker Performance – perfekt für alle, die keine Kompromisse wollen.

Parfait sous tous les points
Produit en parfait état, on ne dirait pas que c'est un produit reconditionné. Je suis réellement satisfait. L'emballage était également parfait! Je recommande sans soucis ce vendeur. Ps: une protection d'écran est installée et une coque est fourni également. Par contre ce n'est pas une version européenne comme écrit dans l'annonce!
