## Description

From the manufacturer

Review: 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
Review: 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
*by A***R on 27 April 2026*

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.
