    WOW! The camera on this phone is totally and mind-blowingly amazing! We take thousands of pictures for our online auction cataloging and this phone will make our inventory stand out like no other. The only thing I hate is that they removed the external SD card slot for expanded storage capacity.

    Camera Makes This Phone Bulky and Heavy

    I am a Samsung loyalist, and when it was time to upgrade I had a hard time finding phones in stock. I settled on the S21 Ultra because there were not any Note20s available. I wish I had waited. The camera on the back makes the phone extremely bulky. There is no S-pen included which was a hard transition for me after having the Note10. As far as functionality of the phone, it's great and exactly what is expected from Samsung. The battery life is great, and this phone has never left me with a dead battery at the end of the day. The phone is fast and camera quality is great. Samsung has the best phones out there, this model was just a miss for me.

    A very quality phone with an amazing camera setup. Battery life is a huge plus and the build feels very solid. Samsung has made the best screens I have ever seen for years and somehow keep getting better.

    The galaxy S21 Ultra is an extremely powerful phone even two years after its release date. The phone is beautiful and just works. The S21 Ultra can take a beating as I am extremely rough with my phones and this is the first phone that has stood up to my daily use patterns. Two years after release it still has jaw dropping features such as 100x zoom and other cameras that work exceptionally well. I highly recommend this phone for absolutely anybody.

    I needed a new cellphone, decided on the S21 Ultra. So it's a little bigger of a phone than I'm used too. Still getting used to it. I like it, but man it's big. The camera is amazing.
