    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. Based on average battery life under typical usage conditions. 5G speeds vary and require optimal network and connection (factors include frequency, bandwidth, congestion).

    Customers are mixed about the quality of the cellular phone. Some mention that the build quality and design is amazing, while others say that it's not a perfect camera. The video quality of this phone is years behind the iPhone and is absolutely horrible. It is a massive disappointment and largely unable to take a usable photo.

    Customers are mixed about the performance of the cellular phone. Some mention that the speed is astounding, it's beyond user friendly, and is excellent and trouble free. Others say that it stops about 3 times a day and says no reception, and that they have to restart it quite a bit. They also mention that when the re-charging exceeds 90%, the phone keeps shutting down and that just pushing the power button causes them to crash.

    "...From the ease of connecting Samsung peripherals (I have Galaxy Buds+ and a Galaxy Watch 3) to the extended screenshot feature to the baked in screen..." Read more

    44 customers mention15 positive29 negative

    Customers are mixed about the storage space of the cellular phone. Some mention that it has so much more memory than they need, and the camera is incredible. Others say that it's also a pity that it doesn't have a memory expansion slot, as previos versions did. There is also no way to add to your storage with a Micro SD card, so if you need a lot of space, you'll have to buy a different phone.

    "...The only draw back is not bring able to add an SD card me I could on previous models...." Read more

    "...They both have the same 8gb of ram, the same storage sizes, same resolution, same cameras, same material, same flat screen, the same backwards..." Read more

    "...It's almost laughable. A phone that can record 8K video has no SD card slot to capture those huge files. Samsung, you're losing my loyalty!..." Read more

    "...Finally, the biggest issue for me, is the total lack of an SD card slot...." Read more

    44 customers mention24 positive20 negative

    Customers are mixed about the value of the cellular phone. Some mention it's worth the money, while others say it' s expensive but delivers. However, some customers love it and say it is the best phone they have ever had.

    "...It’s a very good buy, but be prepared for cloud storage down the road, that is if you plan on taking tons of pics, an/or videos...." Read more

    "...I definitely will recommend phone to others, but the expense is high...." Read more

    "...The price makes this even better." Read more

    "...I can't really get the negative comments. Yes, it's not cheap. The best camera ever. The best screen ever. Great sw, great hw. How could it be cheap?..." Read more

    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.
