    Fragile screen. I have been with the Samsung note from 5 to 20 and i switch to galaxy s22. It just falls from my hand to the table and the screen cracked. It was spectacular... unbelievable...

    Worst phone I've ever owned! This phone is cheap and has lousy battery life. Plastic with only 5G or switches to LTE+ only! If you have wifi enabled when you're in the car you will not be able to connect to anything using mobile because the wifi takes priority evidently! You have to manually disable wifi to connect to mobile! I hate this phone with a passion and plan on taking it to the range! Verizon or Samsung needs to fix this major flaw immediately!

    Customer support can do nothing of professional help when the product you order online and is shipped is not the condition that was ordered and expected. It was an open box excellent condition order. They don't try to make the order good and make changes that are not helpful.

    The Samsung Galaxy S21 Ultra 5G 128GB is a powerhouse of a smartphone. With its stunning 6.8-inch Dynamic AMOLED display, the visuals are breathtaking, and the 5G connectivity ensures fast internet speeds. The 128GB of storage provides ample space for apps.The camera system is great, capturing sharp and vibrant photos, and the 100x Space Zoom is a fun feature to play with. The phone's performance is top-notch, thanks to the Snapdragon 888 processor and 12GB of RAM. Overall, it's a great device for those who demand the best in terms of display, camera, and performance.

    I upgraded from the galaxy S10+ to get this phone and WOW what a huge deal...... I'm talking about speed, the refresh rate, everything about this phone is just great. The camera quality is something that people should definitely look into if you're looking to get this phone you won't go wrong. The laser focus isn't the best when zoomed to 100. But it gets the job done. I go to work from 7:00 in the morning and at the end of the day I have at least 30% left of battery. When I get off work because I'm not on my phone as much I have 80% battery. I love what Samsung has done with the battery. One thing I wish Samsung would have done was make it easier to transfer an older watch to the newer phone I had to buy a new watch because it would not link with this one and I tried everything that I could. Overall great phone!!!!!

    A Professional Camera With a Phone attached

    I have used IPhones ever since there has been a OPhone Thay was until the Samsung Ultra woth its cameras blew away IPhone beyond explanation. Yhe forst photos I took were wiyh the zoom at 60X, they were of a full moon, I Would have zoomed in more but at 60 the moon filled the frame I could see every creator in detail when I went past I went past 60X all all I could get at a 100 X was X was part of the moon and it was so clear you couldn't tell it was a digital zoom. The features in the zoom on these lenses has enabled me to produce content for YouTubeAt a professional level I will say the only shortcoming is they don't have an SD card so I need to off load my high definition I hide definition 8K not 4KI definition 8K it's indescribable

    Switched from an iphone and i am beyond happy. Have had for almost a year now and i still love it. Center screen did crack right down the middle and im unsure why but insurance covers the screen replacement. Camera is great, i only charge it every couple days. All around a great phone.

    I've had this phone for over a year now and have had zero issues! I use it for work and it lasts long shifts no problem! And the camera quality 9/10 times leaves me having the nicest quality out of any group of people I'm with; can't complain!

    This is my first modern phone. (Everything was either a cheap knock off or a hand me down). The camera is amazing, Samsung wallet is super convenient, the UI is really simple and highly customizable. You can set it up so that it's all at your fingertips. The battery lasts me the whole day; the memory size is good since I have a plethora of apps that I use (mainly games) speaking of, the crispness of the screen makes games and videos look amazing (even if on YouTube it's only 360p) The phone rarely overheats (only when I'm charging it and playing a game on max settings). I'm sure this phone will last me for the next 5 years (when I plan to upgrade again).

    I have been using this phone for a while. I had an s10 and figured it was time to upgrade. So I chose Samsung's new flagship. The best they had to offer. After a few months of using it, I will say that is isn't bulky, just a bit large. If that's your thing, more power to you. The phone's display, camera and battery life as well as performance on streaming and most games is wildly impressive. Low light, no light, too much light, the cameras don't care. Couldn't be happier.

    Few takeaways: 1. The Galaxy S21 Ultra offers the best premium Android experience, thanks to powerful hardware and a more refined software that closely integrates Microsoft services and the connected ecosystem experience. 2. The high-resolution primary camera, coupled with an ultra-wide lens and two telephoto lenses for zoom, offers a versatile photography and videography experience. 3. Elegant design, classic black finish, stellar display and a battery that lasts a day, all make the Galaxy S21 Ultra a fully loaded smartphone for power users.
