Great phone and excellent condition! I’m very happy with my Samsung Galaxy S23 Ultra. The phone arrived in excellent condition and looks almost brand new. The lavender color is beautiful, the screen is amazing, and the camera takes great pictures. Everything works perfectly, and the 512GB of storage is a huge plus. I’m very satisfied with this purchase and would definitely recommend it! ... show more

I am so happy with this little beast! It arrived in 2 days, the seller is Cellfeee. Its refurbished good but I couldn't find ANY scratches on the body nor on the screen. Setting up was a breeze, smart switch did the trick. I was up & running in 30 minutes or less. It's a beautiful phone, I got the S23 Ultra 512g 12g ram for a very good price. The speed is mind blowing after coming from my old note 20 with only 4g of ram. I got the ultra for the Spen. I can't live without the little guy. My case & screen protector arrived same day, cool huh... I do recommend getting the curved glass screen protector bcuz it covers the entire screen. The others just sit on top leaving the edges open to easily pealing off. Samsung took out some bloat but still restricts freedom of choice as to being able to uninstall junk. Not that big a deal for me. It arrived with 10% but after plugging into my fast charger was full in just about an hour. Been taking it thru lots of work & play & still have 65% after nearly 24 hours. Great battery so far. It performs like a brand new phone. It is a bit heftier than my note 20 but I don't mind that. I did notice the price on these going up all over the place on Amazon so I consider myself lucky to have gotten this one at the price of less than $500. I highly recommend the seller & this phone & thank you Amazon. 5 stars all 'round! 😁⭐😎💖 ... show more

My Review Of The Samsung S23 Ultra
I've been using the Samsung Galaxy S23 Ultra for almost a year now, and honestly, it's still the phone that makes me go “wow” pretty much every day. The screen is ridiculous in the best way. That 6.8-inch Dynamic AMOLED with the super-smooth 120Hz refresh rate feels like butter, whether I'm doom-scrolling X at 2 a.m. or editing photos outside in bright sunlight (the brightness is no joke, it legit gets stupidly bright). Colors pop without looking cartoonish, and watching anything HDR on it is basically a religious experience. The cameras… okay, look, I’m that annoying friend who takes way too many pictures, and this thing spoils you rotten. The 200MP main sensor is overkill in the best possible way—zoom in on a photo you took from across the street and you can still read the text on someone’s shirt. 100x Space Zoom is mostly a party trick (it gets shaky past 30x unless you’ve got tripod arms), but 10x optical is actually usable and looks clean. Night mode is straight-up witchcraft; I’ve taken shots in near darkness that look like they were taken at dusk. Performance is boring in the best way possible—it just never stutters. I’ve got 50+ tabs open in Chrome, Spotify running, editing 4K video in CapCut, and it doesn’t even break a sweat. Battery life surprised me too. With heavy use (always-on display, 5G, location on, lots of camera), I’m still ending most days with 30-40% left. Throw it on a 45W charger and it’s at 70% in like 30 minutes. The S Pen is lowkey one of my favorite things. I use it for quick notes when I’m too lazy to type, doodling on screenshots, and signing PDFs without printing anything. Feels way more natural than I expected. A couple small gripes, because nothing’s perfect: - It’s a big boy. One-handed use is a stretch (literally). - Fingerprint magnet on the back, but a case fixes that. - Still some Samsung bloatware, though it’s gotten better. If you’re the kind of person who wants the absolute best Android phone and doesn’t mind the size or the price tag, the S23 Ultra is still holding the crown going into late 2025. Even with the S24 Ultra and S25 Ultra out, I’m not feeling upgrade itch at all. This thing is just that good. 9.5/10, would (and probably will) buy again. ... show more

Vendieron celular bloqueado

me vendieron el celular diciendo que estaba desbloqueado pero lo recibí bloqueado... Intenté desbloquearlo en mi país, Perú, pero es imposible, por lo que procedí a solicitar el desbloqueo a AT&T pero indica que está bloqueado porque sigue vinculada con una cuenta, al contactarme con electronic deals para que me ayuden a contactarse con el propietario anterior para que desvincule su cuenta con el celular o pague sus recibos pendientes, electronic deals no asume su responsabilidad diciendo que porque ya pasó meses, pudiendo contactarse con el anterior propietario y pedir que desvincule su cuenta...mientras tanto, yo seguiré con un celular que no lo he podido usar desde que lo compré... No recomiendo al proveedor electronic deals ... show more

Excellent Condition: 512GB
Color: Cream Service provider: Unlocked Memory Storage Capacity: 512 GB Product grade: Renewed
Received in excellent condition. Boots from sleep snappy enough and fast charging doesn't take long to get to full charge. Large comfortable screen, surprisingly easy on the hand. Bright screen with vivid colors and WiFi + cell connectivity feels quick and sharp. Coming from the S21+, I absolutely appreciate the build quality of the Samsung S-Series devices. The security and OS updates prompted much of the switching, but honestly I don't think I was missing anything. Except maybe for the extra storage space and camera leap. Hands down, S23 Ultra is the sweet spot of upgrade and functionality. I will definitely recommend the S23 Ultra and S24 Ultra as well. ... show more

I just got this phone yesterday and it's amazing. There are a few scratches on the volume button but it doesn't affect how the phone operates so I'm not too worried. It was super easy to transfer my eSIM over. This phone is fast and has amazing camera quality. I definitely would recommend.

Pleasantly surprised!

I have to say, I initially had mixed emotions about this purchase. The initial Amazon listing had 5 star reviews so I was excited. It wasn't until after I ordered that I decided to look at the sellers reviews and rgere were TONS of 1 star reviews such as the phones being damaged, inaccurate listing, phones never arriving, or even not getting a full refund or restock fees for returning. So of course after reading all this I'm terrified I wasted $500. But the phone arrived overnight, and you'd never know it was refurbished. Not a single scratch or dent. No issues transferring everything. So far I'm happy with my purchase! ... show more
