A Professional Camera With a Phone attached
Posted .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

Do NOT get there S21 Ultra!
|Posted .Owned for 3 months when reviewed.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!

Galaxy S21 Ultra
|Posted .Owned for less than 1 week when reviewed.I wasn't exactly sure which type of phone to purchase when I first walked into Best Buy. I was deciding between the Google Pixel 5 and Samsung Galaxy S21. However, after talking more to the best buy associate, Taylor, I came to realize that the Galaxy S21 Ultra was tailored more for my needs. Thanks to Taylor, I realized that the Ultra existed and was capable of producing such high resolution photos, along with special features such as the director's view. That was enough to sale it for me. Although I was a little worried about how large the phone would be compared to my prior one, I do not regret the decision. Overall, I love the phone's capabilities and I'm so impressed by how well the photos turned out on my recent hike! I am so fortunate to have been helped out by Taylor in my phone selection process. Taylor was easy to talk to and provided exceptional customer service by going out of her way to answer all of my questions, as well as offer honest advice in my purchasing decision.
