Samsung Electronics Samsung Galaxy S21 Ultra 5G | Factory Unlocked Android Cell Phone | US Version 5G Smartphone | Pro-Grade Camera, 108MP High Res | 128GB, Black (SM-G998UZKAXAA) (Renewed)

Purchased device in March 2023. Worked perfectly with no slowdown or battery issues issues until I decided to upgrade June 2026.

Excellent!! Arrived faster than expected. Condition is like brand new. Work perfectly. I am very happy with my purchase!

I was very apprehensive about buying a refurbished phone but after reading so many 5 star reviews i pulled the trigger. The first one i got looked brand new cosmetically but any time i would go to charge it it said there was "Water in the charging port" and wouldn't let me charge the phone (there was no water anywhere near the phone, let alone in the charging port). That kept happening until i returned it for another one. This one (got it in March of 2023) looked great too cosmetically but functionality is the big issue. First it wouldn't give me any notifications of emails - I went through all the prompts and settings, changed everything I could...still no notifications of emails. The only time it will notify me is if I actually open up Gmail - then it will pop up saying you have x amount of unread messages but if I'm already opening the program it's completely useless! Then I started having people tell me "I was calling you but it went straight to voicemail" I thought it was odd but maybe it was service related. I went to my wireless provider and they said there is nothing wrong with the service it's probably the device. My wife has the same exact service with a different phone and has service throughout the house. Now not only can i not make or receive calls in my house I can't send text messages! The phone will say I have full service (5 bars) plus I'm connected to Wifi 6 with a 1 gig fiber connection. When I go to send a message it will just keep spinning and spinning until the message times out after a long time. The only way I've figured out how to trick the phone into sending messages is send the message, turn the phone on airplane mode and then switch airplane mode off again and the message will send. To add insult to injury last month I noticed a small artifact on the screen that does not go away. I've had this phone for less than a year and I have a permanent line on the screen that shows even when it's on the charging screen. I purchased this from the seller "TheGadgetDeals" because they had 100% positive reviews - not sure how that's possible if these are the kind of phones they are selling. So with no email notifications, no ability to make or receive calls or send text messages in my house (and a lot of times other places) I effectively have a $450 paper weight masquerading as a phone. If you're ok with spending nearly $500 on a phone that will be essentially unusable within 7 months of purchasing I say go for it, otherwise I'd look elsewhere! 1/10 WOULD NOT RECOMMEND PS. After owning the phone for a month or so i purchased another one for my wife (also from TheGadgetDeals) her phone came in excellent cosmetic condition but every time she would make or receive a call the person on the other end would hear an echo of everything they said so that phone had to returned

Needed a phone, and upgraded to this one. Saved a good amount of money too. Was hesitant at first, but happy I went with this one. Absolutely no problems with the phone, everything works 100%. Has slight cosmetic wear, but thats to be expected with a refurbished item. 10/10 would buy another phone from here.

I’ve spent the last number of years using a slew of different phones from OnePlus, LG, Motorola, Huawei, Sony, and the last HTC. I haven’t used a Samsung since the S7. I’ve avoided them because while they were well built, they had software that was so bloated, it drove me nuts. So, what is it like going to Samsung after so long? HARDWARE Back in the day, only Apple rivaled Samsung when it came to the best hardware. Samsung can no longer make that claim. Granted, this phone is excellent, but OnePlus, LG, and Apple are all on the same level in terms of quality build. This phone feels heavy in your hand. I personally like that, but someone coming from an Apple might be very disappointed. Going light weight was not a big consideration here. It seems like they were more focused on packing as much as possible into this phone. That leads to a big issue. Samsung has been cowed into trying to be like Apple and removed both the headphones jack and sd card slot. I see no real reason for this beyond saving money. Apple and Samsung claim that they can’t fit it in, or that no one uses them anymore. Both of those are nothing but lame excuse. Both LG and Sony put both items into their last flagships. LG in fact released HD audio to go with the headphones jack. After using both phones, I REALLY miss both those items. They added a huge amount of functionality and made doing certain things so much easier. They did add the latest and greatest 5G and Wifi connectivity to this phone. That sounds great, but I haven’t noticed it all. I even live in an area where 5G is everywhere. There might be more speed, but everything in my area was already fast. It’s hard to really notice a difference unless you are running a speed test. So, this phone is S-Pen compatible. Great. It would be really good if it actually came with an S-Pen, but you’ll have to pay more for that. By more I mean $40 for an s-pen designed for the Ultra, that is missing some functionality. That’s right, you can’t do gestures. If that’s important to you, you need to wait for the S-Pen Pro to be released “later” in 2021. That one will have a BT connection. That really seems like a fumble on Samsung’s part. I can understand making the s-pen optional and not having a silo for it, like on the Note, but not having the full-blown version available at launch feels like they are missing an opportunity. If people get the regular s-pen, decide they don’t use it, what’s to motivate them into getting the pro version? The S-pen can be handy, but it only makes sense if you get a case that can hold. Thankfully Spigen makes one that is cheap and works well. On the plus side, this phone has the fastest, most accurate fingerprint reader I’ve ever used. It’s easily twice as fast as the one LG was using. The ultrasonic format really makes a difference. CAMERA When I first used the Huawei P20 Pro, I was blown away by how good that camera was. The things it did were unprecedented in a camera phone. I used a number of phones after that one, and none of them ever matched what Huawei could pull off. Samsung crushed it with this camera setup. The flexibility it offers is unmatched. From wide angle to super zoom, it’s all there. Some of the tricks they pull off with this camera are truly impressive. From how it combines photos for optimal exposure to the foolish 100x superzoom, the things you can do with this camera are insane. The 100x is nothing you’ll want to use a lot. It’s usable, but not overly clear. Still, the mere fact that you can take a usable 100x photo with this phone is mind blowing. When I say “usable” I mean a photo that is identifiable. It’s nothing I’m going to want to hang on a wall, but it might help trying to identify something. If there is one thing camera doesn’t do great, it’s exposure. It tends to over expose, but that’s it. That’s the only real issue I can find and it’s minor. You might see the 108MP sensor and think you can take some insane RAW photos with that. To a degree, that’s true, but with a sensor like that, you’d need a HUGE amount of light to be able to get good results. There is a reason why Samsung does pixel binning to get its incredible results. On its own 108MP in a sensor that size is not really usable, except in ideal conditions. I love a good wide-angle camera. LG was always a proponent of the wide-angle, and over the years, it’s really come in handy. It’s not something you use a lot, but when you need it, nothing beats it. You get two tele-photo lenses here. The 3X is great for framing your photos, and the 10x allows you to do things that no over phone I’ve ever used has allowed. The 10x really comes in handy for sunsets and times when you can’t get close to your subject. CHARGING I usually don’t do a write up on charging, but in this case, I think it’s needed. You have wired 25W or wireless 10W. I love that flexibility. It’s not all good though. You know what really stinks? Paying through the nose for a phone, opening the box, and not getting a charger. That’s right. No charger in the box. If you want one, you’ll be paying for it. It’s hard to wrap your head around the fact that they charge you over $1,000, but couldn’t give you a charger. I can’t remember the last time I got a phone with no charger. SCREEN Till now, OnePlus had the best screen I’d seen in a phone. It makes sense that Samsung would beat them, considering OnePlus got their screens from Samsung. This screen is amazing. It’s not just it’s looks either. They did some impressive trickery here too. The adaptive refresh is amazing. The big issue with a 120 refresh rate is the battery it burns through. With adaptive turned on, it adjusts. Reading a book or something similar – it drops as low as 10. This saves a huge amount of battery life. BATTERY LIFE It’s good. It’s not LG V60 good, but it’s good. There have been times when the LG V60 lasted me for two days with normal use. This one has the same battery, but doesn’t last that long. It will easily make it through the day and night though. SOFTWARE Welcome to the worst part about this phone. I know why Samsung doesn’t fix it too. To be honest, I hate the Samsung apps, I hate the excessive bloatware, and Bixby is the worst virtual assistant I’ve ever used. The UI is the more frustrating of the issues here. The main reason is tied to the fact that this is an Android phone. Why do you want to be so different from stock when it’s actually hindering the experience instead of improving it? I understand what Samsung is trying to do. They want to be Apple. They want their own ecosystem, they control, and reap large profits off of. That’s why they have their own assistant, apps, and UI. I’d applaud them for that, if they grow a pair and divorce Android. The only way all the apps, bloatware, assistant, and UI make sense if they are on their own. Just do it already. Become the third option, because as it stands now, your software is awful. It’s trying to sit on a fence, which means it’s not as good as it could be on its own, and it’s NO WHERE as good as stock Android. Now, if you are a handy when it comes to Android, you can remove a lot of the junk off this phone, via ADB. But, stop and think about that for a moment. You just paid top dollar for a phone, and now, you have to waste a solid hour of your time stripping off all the garbage they piled on there. How is that acceptable? If this phone was running software close to stock and didn’t have the bloatware issue, we’d be talking about a legendary phone. One of the best phones ever made. Instead, we have some of the best hardware ever combined in a phone, with steaming pile of dung laid on top of it. Again, if Samsung finally broke free of Android, I think things would be very different. They might also be watching Huawei very closely to see how everything pans out for them. Huawei was forced off Android and now runs its own OS and ecosystem. If it goes well for Huawei, I would not be surprised to see Samsung finally pull the trigger. They already have the OS. It’s been in their Smart appliances for years. I know I’ve bashed Samsung a lot here, but there are some things that do that are excellent. The first one I’ll mention is something that falls into the useful category. It’s their side tabs. The default is your recent apps or apps you’ve pinned. This comes in handy since I don’t like either of Samsung’s default launcher options. You can also add more tabs like weather and select contacts. I first used this with the S6 Edge and I’m glad it’s still around. Now for the thing that Samsung does best, and by best, I mean no one is even close. A deep dive into the sound settings will take you to an EQ setting. This is not impressive on its own, since most other makers offer this. What Samsung does that no one else does, is it gives you a hearing test and creates a custom sound profile for you. As someone who has hearing loss, the impact this has is incredible. The only thing I don’t understand is why it’s so buried. I mean you need to dig to find this thing. I find it rather ironic that Samsung is more on board with Windows integration than any other maker I’ve used. Samsung imbedded the features needed and allows you to use apps in Windows. The others I’ve used require you to download an app and you cannot use apps in Windows. This is a handy feature to have for anyone using an Windows PC. They also support the cut and paste feature. Copy on your phone – paste on your PC and vice versa. I have to relate one final frustrating issue with Samsung’s software. The last three phones I used all were on board with Google’s autofill for apps. That made signing into a new phone an easy experience. Samsung has its own thing. I spent quite a while hunting down passwords that I hadn’t used in nearly two years. WILDCARD There is a factor to consider, if you’ve only used Apple or Samsung products. You’ve been spoiled. By buying the most popular phones, you’ve always had a massive selection of cases and accessories. As someone who’s been using the fringe players for years, I’ve been stuck with only a few choices when it comes to cases. Sometimes it was very difficult to find cases, or I had to pay more than I would have liked. Having a massive selection does add to the value, since you end up paying less for cases as everyone tries to undercut each other. On top of that, you can find the crazy cases that include extra battery, wallets, and added functionality. If you’re using a Sony or OnePlus, you can only dream about such a thing. This becomes even more of a value I you are one of the people in a program like Amazon Vine. I was able to get three cases for this phone, through Vine. Before this, only once was I able to find a case for my phone. Another factor is that there are also apps on the Play Store that are dedicated to tweaking the Samsung experience. Some of them are quite useful. This is something you don’t find when using the minor players. VALUE Is this phone a good value? No. I’m sorry at its retail price, it’s not. The LG V60 might have a weaker camera and older processor, but it’s a far better value. The OnePlus 9 Pro, is a slightly better value, if we are talking about a full priced phone. If you want this phone to be a value, you need to land this phone for $900 or less. Anything higher just isn’t worth it. If you’re going to pay full price for this phone, you might want to look at the iPhone. I do not like iOS, but they have an excellent build, great camera, no bloatware, and fast updates. SHOULD YOU BUY THIS PHONE If money is not an issue and you love Samsung – yes. If money is no issue and you want the best camera – yes. If money is no issue and you want the best Android phone – maybe. If money is an issue and you want a great Android phone – buy the LG V60. If you want a clean Android experience – buy the Pixel 5 or OnePlus 9 Pro. If money isn’t an issue and you want the best phone – buy the iPhone 12 Pro Max. If you need to have a sd card and headphones jack – buy the LG V60. If you need to have a sd card and headphones jack, but hate LGs software – buy the Sony Xperia 1 II.

Luv the phone it has the best camera on a phone I've ever had shots are clear and precise. Zoom is clear first time I've had a phone where the zoom is clear especially when taking pictures of birds it actually looks like one actually the Samsung Galaxy s21 ultra camera is by far better than the Samsung Galaxy s25

No fault

The phone works but the burn in on the screen is bad, it's obvious that the screen wasn't replaced because you can still see the keyboard even when it's not pulled up. It casts a yellowish/orange tint across where the keyboard usually is.

Al momento de abrirlo y sacarlo el celular se veía nuevo literal Pero ya viendo de cerca me percate que tiene unos rayones poco profundos en las esquinas del crista solo me di cuenta porque se ve a contra luz y fijándose bien porque si no ni te das cuenta que están ahí de verdad parece nuevo Otra cosa que la tapa trasera como que se está despegando Pero eso siempre me a pasado con los celulares de Samsung después del año les pasa eso de hecho me comentaron una vez que cada año hay que cambiar el pegamento para que no pierda la certificacion contra agua y polvo Otra la batería bien pero tiene un 86% de vida Pero en las especificaciones dice que mínimo debe tener el 80 pues cumple ami en modo de ahorro de energia y bajando la resolución a hd me dura unas 10 horas en pantalla y va muy fluido incluso con los 120 hertz apagados La neta por lo que pague que fueron 8600 fue una ganga gama alta premiun tiene de todo lo mejor de lo mejor actualizaciones hasta 2026 todo el año para cambiarlo en el 2027 excelente cámaras y no le pide nada a los nuevos s23 La neta tener un s23ultra a un s21 ultra no se siente la diferencia en experiencia y en mano sólo creo que le gana en batería pero pagarías 30mil pesos que en 6 meses costaría 20 Siempre he tenido gamas altas de Samsung y ahora vengo de un flip 4 con el procesador g1plus snapdragon y es una chingonada el flip me costo 28mil lo vendí en 15 y me compre este porque quería tener todo al tope pero como me gaste la lana en el flip y se devaluado pues me compre este es mucho mejor que el flip pero la pantalla del flip se ve como una oled no como superamoled el hdr super chingon en el flip pero creo que media pulgada más ancha la pantalla del flip estaría excelente en que esta delgada y tiene esos bordes negros eso no me gusto Pero los bordes del los ultra se ven más elegante Bueno eso es todo 👍

El celular llegó en muy buenas condiciones! Recomiendo la compra de reacondicionados en Amazon, ya pedí el segundo espero que llegue igual de bien.

El estado estético del celular fue impecable, como si fuera completamente nuevo, las cámaras están geniales, la pantalla es poco más grande que el iPhone 14 Pro Max, aguanta muy bien la batería, la pantalla está perfecta, tenía solo miedo por el tema del chip por ser versión estadounidense, pero funcionó muy bien con Movistar. Llega en una caja genérica de re acondicionado de Amazon, un cargador genérico y el celular bien envuelto junto su llave para el chip.

La verdad es que la estética llego excelente, 9.5 en ese aspecto, al inició tendía mucho a calentarse pero afortunadamente se fue optimizando y mejoro, llevo 6 meses con el y estoy muy contento, no ha fallado nada, incluso el ip68 sigue funcionando, nade y grabe con el, aunque tuve suerte, no es recomendable hacer esto con reacondicionados, la batería es su punto débil, pues sí lo uso mucho, no llega sl final del día y por ratos aún se calienta en juegos pero nada del otro mundo y creo este modelo incluso nuevo traía eso detalles, las camaras excelentes, por ratos el sensor y actualizará hasta Android 15 entonces super bien, creo que si lo consiguen por menos de 10000-10500, es una super compra, años luz mejor que cualquier gama media nuevo de ese rango de precios.

El teléfono venia en perfectas condiciones estéticas excepto por la tapa trasera ligeramente despegada unos milímetros imperceptible a simple vista ,sin embargo me hace creer que no fue bien pegado o si con el calor se vaya a despegar. En cuanto el rendimiento y funcionamiento en general todo bien.
