    Product Description

    The Samsung Galaxy S21 Ultra 5G phone is epic in every way, with a striking new design, fastest Galaxy processor yet, a battery that goes all day and then some, and the first Galaxy ever supporting super smooth 120Hz screen refresh rate at WQHD+ resolution, it’s no surprise why Ultra easily lives up to its name. We know your life moves fast, and there’s a fine line between what makes a moment ordinary and what makes it extraordinary. That’s why Galaxy S21 Ultra 5G is purposefully crafted so you don’t need to choose between video and photo. With a single tap, you can pull super-clear stills — up to 33MP — straight from high-resolution 8K video. Use the 108MP high-resolution camera for still shots that come out crystal clear whether it’s day or night. Single Take AI transcends the usual restrictions of photo and video editing to capture life’s greatest moments, wherever they happen, in one single take, capturing images and video for up to 15 seconds. Experience the power of the Galaxy S21 5G series. Innovative and beautifully designed, Samsung 5G phones emphasize the brand’s dedication to the latest cutting-edge technology and next-generation connectivity. Enjoy more sharing, more streaming, more experiences, and more connections at lightning-fast speed. The Galaxy S21+ 5G does not currently support eSim in the U.S. Battery power consumption depends on usage patterns and results may vary. 5G speeds vary and require optimal network and connection (factors include frequency, bandwidth, congestion).

    Most amazing phone ever
    5 Stars
    Most amazing phone ever
    This is the most amazing phone I've ever owned.. Up until this point there have been minor improvements on various functionality and speed and so on. This phone has all of that and the most amazing camera you can imagine. As you can see from the photos I posted the night vision is amazing. The picture of my pool area is at night with no moon. If you hold the camera steady enough it will take Photos as if it was daytime. But you can see from the lights on the building that we're in the middle of the night. There's a photo of A naval ship coming in to Naval Station Mayport over the horizon. It's miles away. But as you can see you can zoom in and almost see which ship it is. I also was able to put the camera phone on a tripod, and take that photo of an airplane flying a 30000' or higher. Just holding the phone, I snapped a photo of the moon where you can make out mountains clearly. Amazing! Samsung has really set the bar high on this one.

    I wanted to give this phone some full usage before I wrote my review and I can finally get into full detail. Before I jump into my pros vs cons let's just mention my personal final thoughts.
    Get it! Thought over.
    Whether you are transitioning from Apple to Android or just upgrading, this is without question the correct choice. With the latest chipset, processors, camera array, and intelligent software there are so many possibilities.

    Pros:
    1) The battery life is absolutely insane. Now at first I wasn't sure how I felt about the battery. It seemed average after the first day or two of use. But something clicked half way through the third day of use. I had read from articles and watched YouTube reviews from TechTubers about this intelligent software. I expected them to be referencing the Ai. But it is so much deeper in that. This phone continues to monitor your usage and learn the way you operate with it. Pair it with a smart watch to perfectly shift usage and workload. At no point since purchase has this device seemed to struggle. I can comfortably say this is a 2 day phone easily. 2 days of continuous normal usage before needing a recharge.

    2) The finger print reader is vastly improved from previous devices and can now be compared to the likes of devices like One Plus. Yes you will have to spend a good minute or so letting every point of your finger be thoroughly mapped out but it has proven to be lightning fast in response.

    3) This camera...phew. if there was ever a single reason to choose the Ultra variant over the other two it is absolutely due to the camera. Laser focus, combined with smart lenses, and a true melody of beautiful spec options results in a user paradise. One could literally place a fruit, a leaf, and some random option side by side for a shot and notice visible suggestion. The fruit will display a food shot mode. The leaf will suggest aspect ratio options or even the ultrawide/ Auto-Focus macro shot mode. Truly mastering this camera will not only take time but also lot of practice, something I personally look forward to.

    4) This may seem like something that at first should be obvious. But use of this device just truly feels so effortless and fluid. Everything works how I would want it to, and at just a speed that truly leaves you with a sense of relief.

    Cons:
    1) Inevitably as with all Samsung products of course there is some bloatware. But from what I've seen it at least is not overwhelming. A few apps I know I'll never used sprinkled around. But those have just been compiled into a folder and forgotten about.

    2) To some this may be a nuisance so it's worth mentioning. Although this device has an Android OS, it is noticeable the amount of strictly Samsung branded apps/Widgets available. It will take some navigating to better arrange your set up to one's preference. Especially when it comes to something such as utilizing the Google Play Store vs Samsung Store.

    3) Third but maybe most importantly, given the circumstances everyone is facing due to Covid-19 the price is certainly a factor. Even with sales yes this is a price handset. Yes there was a price drop from last year, but that doesn't really soften the blow.

    4) No charging brick. No matter how it is explained or reasoned, the absence of the brick is felt! On first charge I did use a prior usb-C to usb-a charger and wow.....talked about watching paint dry. There was absolutely no way that is truly the best option across the board for all the relevant phone companies. (Ended up buying a usb-c IQ charger from Anker. I think that was like $14 approximately. Definitely an immediate and noticeable remedy, thanks Anker for that save.)

    If one were to say is this phone worth the 999$-1200$ price tag. Honest answer, absolutely, depending on how one plans to use it. If you want the BEST experience out of the three variants (S21, S21+,S21 ultra) there is only one choice. However if that price point just isn't within your budget or path of purchase, I can still say the other two options will suffice also.

    Wireless Provider: UnlockedColor: Phantom BlackMemory Storage Capacity: 256 GBVerified Purchase
    I upgraded from the Galaxy s8 to the S21 Ultra with 256 gb of storage and 12gb of ram. I will start off by saying go with the Ultra or the base, you pay $200 extra for half an inch of screen on the plus (this is called decoy price, you see this at movies where the popcorn medium is only 1 dollar less than the large, but is 3 more than the small, so you might as well go large.)
    I'll give more detial at the end.

    Camera is super high quality, zoom is incredible. Front camera even takes good pics (I mean I looked good, so should you)

    Processor is as advertised, insanely fast, even at the standard limited benchmark (there is an enhanced processing mode to take away cpu 70% limit). Desktop mode is great, this phone is almost as fast in Dex as my actual Acer laptop.

    Battery life is phenomenal, can get 2 full days out of 1 charge if you use the phone less than 4 or 5 hours a day at 1080p res.
    1440p, super clear and one of the bargaining point for the Ultra over the base. The refresh rate of 120 hz is incredible, I spent the first 10 minutes just swiping on the phone in awe of this. The ultra is also the only version with the curved screen,, the s21 and plus have flat screens.. This phone does an excellent job of cooling, even witha case on. (FYI heat causes the major wear and tear on the internal components like the cpu, so better cooling means better lifespan and performance).

    Customizable routines allow you to add features to your phone, from automatically silencing when you show up to work or school, automatically going into power save mode at certain times like when you are asleep, or even for when you turn on your Bluetooth headphones your phone can automatically switch to 1440p resolution and turn Dolby atmos on movie mode sound. Dozens of scenarios or time stamps for each feature.

    If you are the friend that walks on the grass, don't worry about bringing that bulky charger for when your friends' phones are about to die, this phone can wireless charge other devices (will stop charging when the phone drops to 30% minimum).

    If you are concerned about no color options, just remember, I had that beautiful orchid gray s8, and who got to see it? Nobody, because it was hidden behind a lovely teal case for 4 years.

    If the fact that Samsung dropped their charging from the 45w of the s20 series to a 25w for the s21, rest assured, there is very little added time for charging, and the 25w is less volatile than the 45w. This means, charging does not get the phone as hot, and the battery will have a better lifespan since slower charging is better long term.

    If you multi task a ton and/or save tons of files, consider spending the extra money to get the 512 gb edition, as it comes with an additional 4gb of ram (16gb total).
    Ram is what is used to have tabs open, so more ram means more tabs open while still maintaining speed and smoothness. The s21 ultra also has Spen support (need a case that can hold it).

    Why the ultra or base and not the plus?
    The s21 has a better ppi (pixel density, higher the density, better the picture) than the s21 plus. They both have the same 8gb of ram, the same storage sizes, same resolution, same cameras, same material, same flat screen, the same backwards wireless charging capability (same for ultra), etc. The only difference is the screen size and that the s21 plus has a 4800 mAh battery while the s21 has a 4000 mAh. The ultra however, offers higher resolution, much higher ppi, the larger screen, larger battery than both (5000mAh). The ultra has much more powerful camera as well, the curved screen, camera features and settings. So if you want all the features and performance and screen resolution (I like the stream movies on my lunch breaks) then go with the Ultra, if you just want to upgrade to the newest and fastest phone, and you don't need to have 100000 tabs open, get the base s21.

    5.0 out of 5 stars El mejor smartphone de 2021

    Sin duda el mejor Mobile de 2021, la mejor pantalla, la cámara está en el top 3 y si descargas la Gcam ya la conviertes en la mejor cámara del año sin ofender al Pixel y al iPhone (las fotos que tomas con el iPhone 13 Pro son prácticamente las mismas que toambas con el iPhone 11 Pro), el zoom de este móvil destroza al iPhone y a cualquier Pixel, además la ergonomía también es mejor que los anteriormente mencionados; lo único en que si es mejor un iPhone es en la batería, pero no significa que sea una mala batería la del S21 Ultra.

    La mejor compra que puedes hacer pero cuida que sea la versión Snapdragon, sino no puedes descargar la Gcam.

    Compré aquí el Samsung Ultra después de dudarlo muchas veces. Me termine convenciendo por que tenía más de un 35% de descuento y pensé en caso de que haya algún problema después de la garantía de Amazon podré arreglarlo con menos de lo que ahorré.

    A un mes de uso les digo que todo va perfecto. Me llegó al día siguiente el equipo, sin ningún defecto y ha funcionado excelente. No hay tema con la red celular. Las fotos son buenísimas, la rapidez del equipo también.

    A 5 meses de uso les comento que sigue funcionando al 100, no he tenido que recurrir a garantía. Cambié de compañía telefónica 2 veces y no hubo tema tampoco.
