    Samsung just does not disappoint with their phones. Screen crystal display and their cameras in the Ultra are just amazing!

    Best of the S21 Family but not of the S family

    Compared to older versions you are getting less for about the same price. S7, S8, S9, S10, S20 series all had MFT, SD Card slots, heart rate monitor, some had iris scanner, 3.5mm audio jack, advance download (used wifi and mobile data to accelerate download), more flexibility with the Hotspot settings, among other things. Samsung has kind of gone backwards removing all these features and only focusing I guess on camera. If you don't need 5G stay with your older Galaxy S phone for now and wait it out. In my opinion losing 3.5mm audio jack, SD card slot, and MFT for 5G and 120Hz display is not worth it. The only positive thing about this phone compared to older galaxy phones is that finally eSim was enabled.

    Very good camera, speed, screen, many apps and features/settings. But also has bugs, and many updates that are slowly killing the user experience by changing the original state to some unusable conundrum. Avoid downloading updates!

    Great Phone But Get A Screen Protector

    Really great phone, fantastic camera but only lasted 16 months because I dropped it and the screen significantly cracked wrecking the display but the phone actually still worked. I made the mistake of thinking the Gorilla Glass was tough enough to avoid using a screen protector, which I hate using. So now I have the S23 Ultra with a screen protector. The screen gets gets finger prints all over it and the print reader doesnt work as good but the screen is protected. Lesson learned the hard way.

    Bought for my wife. It’s held up very well. Camera was better than my iPhone 12 Max! (about on par with the 14 but at half the price)

    Solid flagship phone from Samsung

    Phenomenal camera for photos, a bit large for smaller hands, great software support from Samsung, great screen, good battery life, maximum available usable screen real estate. A small upgrade from an S20 FE, but definitely feels more premium/flagship. Wish it still supported external memory, but it seems Samsung is following in Apple's footsteps and doing away with external memory.

    It's a great phone. I upgraded from my old LG V60 ThinQ. The battery life is a bit of a downgrade, same as the charging speed. I haven't noticed any other issues. I love the quality of the phone, aswell as its camera. Not quite worth what I paid, but what good phone honestly is nowadays?

    I was due for upgrade on my phone. I looked at other phones and chose to go with s21 ultra because of its camera. This phone has the best camera on the market. It is also fast.

    My wife's old Samsung S8 was starting to slow down and she wanted an upgrade in speed and the quality of the camera since she's always taking photos. The S21 Ultra 5G ticked all the boxes, allowed her to upgrade to the faster 5G network, and takes beautiful pictures. I don't notice a huge difference in processing speed compared to my S10, but the camera on this phone is a very noticeable upgrade. Make sure you get a good case that will protect the lenses though as they stick out from the back of the phone and are prone to scratches.

    It has incredible and flawless hardware but I don't like Samsung's software. For example, I want to set Google Photos as default gallery app. Can't. Even though Samsung could let me if they wanted to. And they could let me delete a lot more apps if they wanted to also. Just don't feel like I control my phone with Samsung. So I use a Pixel instead. Much less powerful hardware but I love the software when it's not buggy
