Fast shipping. Received in 1 day. Big performance phone for productivity (Samsung Dex)
So far this phone performs great. It is fast and very responsive. 16GB of RAM! I could open a lot of apps in the background and it is still running without sluggish. It is new and never been used (I think) since the imei is still good and not being registered. This phone with 512GB storage is sold out pretty much everywhere and you cannot even get them from Samsung website. Don’t buy 128GB. It is useless since the storage is so small. Add $50 and you could get 256GB. However, I recommend 512GB.What is great is the camera. It works a lot better than S20 Ultra 512GB. That one was a let down and I returned it. I stuck with S8 Plus for 4 years but I love that phone. The autofocus and nightime mode improved significantly at least for me. The S20 Ultra autofocus is horrible. It seems the multitasking works a lot better to. App can easily works as popup instead of of multiple presses in s8 plus. Speaker sounds is a bit louder and has more bass sound. Wi-Fi 6 and 5G are definitely the best features. With 5G, I am no longer having blackout in certain area around my house area. When there is no 4G LTE, 5G will take over and when there is no 5G, 4G LTE is taking over. In the past, I only have 4G LTE and 3/2G. You have three different customization on how to switch to different apps (multitasking). I haven’t really go out and use the camera yet although it is the main reason why I am buying this phone. Another plus side is this is a t-mobile version.The only downside is no micro sdcard, 100X space zoom (a feature JOKE from Samsung Marketing department), 3 buttons instead of 4 and finger print from the front display. For finger print, I love the rear touch since it is more convenient to use with one hand. Finger print is a bit troublesome to detect unlike the old one. (Update: You have to press a bit harder on the display to get your fingerprint detected. So far it is working better than I first initialed test). I am hoping Samsung will bring the sd card back in the future. Seriously 108MB, 8k (never use this feature ever), 4k size of photos and videos and you do not provide sd card? Even my Sony A7RIII works great with micro sd card in sd card adapter. There is no excuse of not giving customer sd card option. The excuse of sd card is slowing down phone performance is an old myth provided by none techies or those people who never used sd card. Not sure why the hate on sd card. If you don’t want to don’t use it. Recently so many big companies either getting hacked, attacked with ramsomware or services shutting down cloud drives becoming a joke. Samsung shutting down their own cloud for photos/videos services and Google their unlimited photos. With all the security issues and possible shutdown, it is not a safe approach for storing your photos/videos for backup.To work around it, you can use- USB OTG C to female USB A/C port for USB flash drives- USB OTG sd card hub/ports with sd card readers and USB A/C ports.- 4/5 TB hdd drives are still having reasonable pricing with only small increased in pricing. I am lucky to keep up with the news to buy 8TB to 16TB drives before scalpers took over the market. S21 ultra has the ability to read exFat/fat32 by default and ntfs for small usb flash drives. For large drives like 2/4/5 TB or larger in NTFS format you need other special software to read the NTFS. NTFS format has better storage efficient and security than exFAT and fat32. I am using paragon software to read the ntfs ($9.99) and total commander. For the usb hub station I am using, without a pd power delivery I could not read/write to ntfs hdd drives. I haven’t try it on smaller OTG (USB 2.0/3.0) to see if it is working on hdd drives. Will update on that later.- Buy UHS-II readers to get faster reading/writing speed even if you are not using UHS-II sd cards.Buy one of the USB 3.1 gen 2 cable or gen 2×2 USB C to USB C to reap the 10/20 Gbps (theoretical) speed. I will update more once in the future especially the camera part.Update:I bought a hub station with 5 USB ports (2 x 2.0, 2 x 3.0, 1 x C 3.0) 2 x hdmi, 1 x dp port, ethernet, USB c powered port (100w), UHS II regular sd and micro card reader. This thing has one usb c cable attached which you can connect to your phone. This thing is simply awesome. It is better than my old Samsung Dex which doesn’t come with extra USB ports , extra display ports and sd card readers. With 100w to power this hub station, I can connect to several usb devices without the worry of connection loss issue. Since I am doing a lot of reading I don’t have to use my desktops or laptops. I probably will buy a small battery powered monitor to turn this thing into a “laptop”.Using my hub station, my wireless speed is~478.82 to ~480 Mbps Download from Ookla. Upload is not provided but I assume it is above ~22 Mbps~380 to ~438 Mbps Download from Google. Upload is ~23 MbpsHowever, this is my router and ISP dependable and not the phone. I should have test the phone using the 5g speed on clear and country side. Will update later on that.Next month or so I am going to use a lot of the photography so I could evaluate the camera performance. I know that from few shots, the default auto camera is a lot better than S20 Ultra (which I used only for few days). The autofocus is fast and photo taken is not blurry. The HDR processing makes the photo looks better too. I could see the clouds contour enhancement and colors look a lot better too. What I wanted to know now is the nightime shooting. I did take few snapshot in a darkroom and so far it seems to run perform better than S20 Ultra (which takes 5 to 10 seconds) or something not even getting anything during the autofocus.

Great Phone
Had this phone for a week now and wanted to wait on reviewing. Great solid phone from Samsung (as always). This is my 4th galaxy phone from over the years and I keep returning. The refurb seems to be fine, it was listed in excellent condition by seller (Stalion Requip) and seems to be as described (a few very small nicks along phones sides). I appreciate the honest description and fast delivery as I was apprehensive purchasing a refurb. The phone is spectacular in all areas, battery life, fast fingerprint reader, camera(s), snappy performance, fast charging and so on. I will probably not use the phone to nowhere near its capabilities but wanted the premium features just noted. I do not think I would have paid the original price (approx $1,200.00) just 3 years ago at launch but this is definitely more affordable. Thank you Samsung, Amazon and Stalion Requip. Ned D.

Great product but really bad generic charger 2.1A 10W
The Samsung S21 Ultra has exceeded my expectations in almost every aspect. From its stunning display to its powerhouse performance, this flagship smartphone truly stands out in the crowded market. Let me delve into the details of what makes this device a must-have, while also shedding light on an area that could use some improvement.First and foremost, let’s talk about the display. The S21 Ultra boasts a breathtaking Dynamic AMOLED 2X screen with a 120Hz refresh rate, delivering unparalleled clarity and vibrancy. Whether I’m streaming my favorite movies or gaming with friends, every visual detail pops with stunning realism. It’s like having a cinema in the palm of my hand.Performance-wise, the S21 Ultra is an absolute beast. Powered by the latest Snapdragon processor (or Exynos depending on the region), coupled with generous RAM, this smartphone effortlessly handles multitasking, gaming, and productivity tasks with lightning-fast speed. Apps launch instantly, and I can seamlessly switch between tasks without any lag or stutter.One of the standout features of the S21 Ultra is its camera system. With a quad-camera setup including a 108MP main sensor, 10x optical zoom, and 100x Space Zoom, this phone lets me capture moments with astonishing clarity and detail. Whether it’s a scenic landscape or a close-up shot, the photos turn out sharp and vibrant, even in low light conditions.The sleek design of the S21 Ultra is another aspect that I absolutely adore. From its premium build quality to its ergonomic feel in hand, Samsung has nailed the aesthetics of this device. It’s a perfect blend of style and functionality, making it a pleasure to use and show off.However, no device is without its flaws, and in the case of the S21 Ultra, it’s the included charger. While the smartphone itself supports fast charging up to 25W, the included 2.1A 10W ONLY charger feels somewhat underwhelming. In today’s fast-paced world, where every minute counts, having a more powerful charger would significantly enhance the user experience, allowing for quicker top-ups on the go.

Great phone for price! excellent condition even greater store owners
If you are on the fence about buying a used phone because you are afraid it may come with damage, screen and all sort of issues than worry no more MOBILESUPPLY has amazing devices that are very nice. My device looks basically new, some may have small marks here and there but my devices look amazing. Mark really helped me with my order, the customer service here at MOBILESUPPLY is next to none! their customer service is better than some big chain brands. I want to really thank Mark! Im starting to miss him, such an amazing guy. When my device had a issue Mark on behalf of MOBILESUPPLY worked with me to replace my device and made sure it was inspected to my desires. He was such a kind, nice sweet person and most of all Mark is very professional and unlike other sellers and big brands he CARES about us CUSTOMERS. Thank you MARK for everything I will be telling everyone I know to buy phones from you all.

El equipo jamás decÃa que era reacondicionado, en ningún lado, el celular llegó pero traÃa un rayón súper profundo en la pantalla, lamentablemente lo tuve que devolver por no cumplir las notas, si hubiera dicho reacondicionado me arriesgo y se lo que compro pero no fue asÃ.

Product came in mint condition and works flawlessly. Watch out for the screen protectors that are way too complicated if you order some with the device. Your best to not go with the bundle package including a cheap case and cheaper screen protectors. Those extras ended up in the trash right away!

 Al principio dude pues nunca habÃa comprado algo reacondicionado pero me terminé animando y fue una excelente decisión.El celular es prácticamente nuevo, funciona al 100%, la cámara es increÃble, super profesional, un celular bastante rápido y de super lujo.Venia con pocos detalles estéticos en los bordes, pequeños puntitos sin pintura que realmente no se notan nada, de ahà en fuera el celular venia en excelentes condiciones.5 estrellas definitivamente ðð» me hice de un celular de lujo por un precio super bajo para la gama alta que es. Lo recomiendo mucho.
