    Hands down the best phone I've ever owned. Perfect size for my hands. Lots of memory and quick response with everything i use. Cameras are amazing. See far away things from miles away like they are right in front of you. Highly recommended even if you've never owned a Galaxy before.

    Love this phone. Camera is really nice. Kinda having issues with At&t network connecting to 5G since it is an unlocked version. Went to At&t store and they said this is a common problem. I know of people who have same unlocked phone and can connect with no issues. Overall this phone was a nice upgrade from previous S9+.

    Upgraded 4 year old phones to this model. Everything is great so far but have only had it one day. Camera is fantastic. If I had to say anything negative it would be that they no longer provide the home charger in the box. Not sure why they would do this aside from additional income.

    Best phone I have had so far. I use to use lower end Androids, switch to iPhone for the 7 and 8, then instead of the new iphone, this was a lower price so I decided to give it a go. My parents used Samsung products for a while and they always seemed reliable, and so far, this phone is no exception.

    This thing is the definition of fast, it's smooth ,the display is out of this world. The speakers are loud and very clear. The spen feature makes this and even better experience. But the 120 refresh rate is wow wow wow wow. If you have the money this is a must if you like/love Android and samsung

    This phone is great and right on the edge of being amazing. The camera takes great photos, but it doesn't always work when i push the button, so sometimes the moment is gone. My iPhone 12 Pro Max always gets the shot, and the main camera is just as good. I love that i can swipe left to the Google news feed now and the screen looks amazing. Battery life has been very good.

    The camera on this phone is by far my favorite one! You can zoom in across the room and it will show you in the upper right corner a zoomed out version. The videos also look amazing, even if you move fast from one spot to another it will catch every detail and not look blurry like other phones.

    This phone is amazing, it is really an ultra phone! Huge screen, perfect pictures and very fast to do anything! The battery life is really good, I can use a full day without think about charging. Maybe only the S22 can be better than this one!

    I switched to this from a Pixel 4XL for the camera. It was a very good decision and great investment. I use it exclusively for my product and family photos. It's full of features and takes the most amazing photos I have ever seen from a phone, even at night!

    I was without a phone for 3 weeks - something I never thought would carry such weight. This phone is completely overkill for me, and I use my phone all the time. Definitely looking forward to continued use. Love it so far though! It's gorgeous and the battery life is crazy.

    I have always purchased Samsung phones and am highly satisfied with this one. The camera is great which is an added perk. I have seen reviews that say the camera isn't that good but it just took a few changes of the settings (thanks reddit) and I am very pleased.
