Customers are saying

Customers often highlight the Galaxy S21 Ultra 5G's superb camera quality, ease of use, and impressive battery life. Many appreciate the large screen and fast 5G capabilities. However, some users find the phone's weight to be a drawback, and the lack of expandable storage and a headphone jack are also mentioned as shortcomings. The phone's size is a point of discussion, with some finding it advantageous and others not.

    This phone... i dont even know where to start. This phone is amazing. The camera.. it really does zoom into the moon, and all other pictures are amazing. You can put your camera right up to something it focuses. Sure i use my phone for calls and texting, any phone can do that. But not any phone can have this good of quality for a camera. Only downside is voice-mail, you have to call in to your voice-mail or pay a subscription to not have to call in.

    The quality of this phone all around is poor. I am very disappointed with this product and the response I have recieved from Samsung. This camera caved in and shattered just being in my back pocket. I now can not get this phone fixed becasue the authorized Samsung repair centers don't carry the parts to fix the Navy Blue colored phones.

    Galaxy S21 Ultra, When you want a exceptional smart phone and great camera. I really like the interactive and user-friendly camera. Its great having a flagship phone with many features, great design. Prior to my purchase, the weight was my only concern, and after a week, I didn't notice, as I am accustom to it. The 120hz screen is very sharp, good detail, showing off the pictures I took earlier. Battery is strong and gets you though the day! I got the 128gb, which has plenty of storage, or use external drive or cloud. When talking on the phone, a friend commented how clear the reception is; when I switched from my car system. I enjoy the S21 Ultra,

    Much faster and smoother operation than the S20. Also, once in 5g, it is lightning fast and the Verizon network has been very stable and dependable. Apps run quickly and smoothly. Overall seems to run a bit faster than the predecessor. One minor flaw....no storage card slot or capability. I did not know this and had to load my music in manually. Im not a music streamer. Camera is super sharp and easy to use. I will be keeping this phone for a while.

    Huge upgrade over the Galaxy S8. Super-fast, sharp looking screen, great cameras. Some issues that I saw regarding this phone were the fingerprint reader, but I think I like the version on the screen better than I ever liked the dedicated sensor. I also saw people complain about only having 128gb of memory, but I think it is better to just make sure your data is backed up in the cloud so this kind of encourages that. Happy with my purchase

    This phone is a big step up from my Samsung Note 8. The feel of the phone is about the same but it is much faster and the camera is awesome. I feel like a real photographer. I don't feel that it is as sensitive as my Note 8, but I have gotten used to that. there is a lot of bloatware that I removed before I downloaded the apps from my old phone. This phone is nice but a little pricey.

    Super expensive, we will use them until they die(my husband and I got the same phones). Overall we like it, even though it has some issues. Battery life is pretty good and I love the camera. I am still learning to use it even though I've had it for at least 2 years

    The phone is great- quick, responsive, and the camera is amazing! The videos it takes look like they could be on TV. Downsides-the lack of the SD card slot. I didn't have time to wait for a larger capacity phone to be available. Everything other than 125GB is unavailable/sold out. Hella dumb that their is no headphone jack, but you can get an adapter. Lastly, why have a phone that can utilize the stylist but not include one, or a place to store such a small thing?

    I honestly have to say, i have had a Samsung Phone since the Note 8 debuted. Although I really liked everything about the note8, it was time for an upgrade. I read the specs for almost every phone in the Samsung lineup and decided on the S21 Ultra+5g. Although it has some really good specs such as improved battery, better camera(s) 120hz, HDR+ , and a decent processor, the overall feel and performance of the S21 is mediocre and uninspiring. I gave the phone 4 stars for the specs, not the excitibility. I should have waited for the S22 ultra 5G!!! I miss my Note8 which is ancient in today's world

    I have been a long-time Samsung follower since my first Samsung smart phone from 2011. I have been holding on to my Samsung S9+ for years and realized that it was time to upgrade. Typically Samsung comes out with new devices, often. So I waited but when I saw the S21 Ultra, I knew it was tome to upgrade. So far, I love it! Like most quality Samsung model classes; the ultra feels great in my hand... though it took me awhile to get used to the screen being where the finger lock is and the giant fly eye cameras in the back. But once I got used to the feel, I have found that I am excited about using the phone, again. And taking lots of pictures! The pictures are amazing! And the apps, as of now, run smoothly. It's much easier to play games on it, too. If you are looking for something new and of quality, this has to be the best camera phone in the market.

    Samsung Galaxy S21 Ultra 5G - good phone

    Replaced my Samsung Galaxy S7 with the S21 Ultra 5G. At this time, I've only had the phone a week. It takes a little getting use to after using the S7 for so many years. The screen is bigger, all icons, images, text, etc. are very crisp and clear. I still have much to learn on this phone. I do like there are new and more sounds to choose from for notification for text message, phone calls, alarms, etc. So far, I like it. The couple of things I find hard to get use to, there is no LED indicator to show I have an unread message. The S7 had a button at the bottom of the screen. You tap the button and it activates the phone to come out of sleep mode. The S21 does not have that button. Instead you have to use the button on the side of the phone. Its an adjustment.

    Amazing camera and speed, much faster than my Note 10 Plus! I don't find it's size to be huge, my Note 10 was about the same size and I got used to it. Battery lasts all day, go home after work and is still at 50% or more!
