Customers are saying

Customers commend the Galaxy S21 5G 128GB for its exceptional camera quality, impressive battery life, and user-friendly interface. Many appreciate the phone's size and performance capabilities, along with its 5G connectivity. However, some users express disappointment over the lack of a headphone jack and an SD card slot. The positive feedback on the camera and battery life significantly outweighs the negative comments regarding missing features.

    With the exception of the fact that you can not longer add an sd card for memory and they have done away with a headphone jack, I really like this phone. The camera is really fantastic and i still havent uncovered all of the features it offers.

    I was surprised how fast this phone is. Feels good in the hand. Camera is crisp and 8k video is really good. If deciding between apple and this phone, this phone has better response and navigation through the apps. 4 stars because it is a bit tall.

    Works great! I enjoy how bright the screen is and colors look great. Phone is not too big and still fits into pants and coat pockets.

    This is my third Galaxy phone. I absolutely love the phone! It takes great photos and video. Samsung has one of the best screens you will find on a phone. So far battery life has been excellent.

    A Great Phone at a Good Price

    The Galaxy S22 is right around the corner, so that means right now you can get a good deal on an S21. The S21 is not Samsung's flagship phone (for that, you need to get the S21 Ultra), but it's still a great phone for a reasonable price. The S21 is a nice upgrade to my Galaxy S10, which itself is still a great phone today. The S21 has a fantastic display, and it's extremely smooth. It also boasts a top-of-the-line camera. You can't go wrong with this phone at this price.

    Good phone but I don't like the volume very well. I'm not happy that they took the heart rate sensor off.

    Great phone. The auto correct function on my last phone was easier to deal with, but that's a small thing. Very fast. EXCELLENT pictures!

    Great phone and love the 30x camera zoom and totally flat glass screen. NOTE: Samsung is no longer putting MicroSD card slots in their phones. Keep this in mind when deciding how much internal storage you need!

    Moved from an s20 ultra to this. Screen image is amazing chargers fast. Good camera. Issue which is why I have to give 4 stars this thing but s through the battery. I did all tricks I could to save battery life that I had on my s20 ultra. I got 6 hours of use and dropped 70% from full. My s20ultra would last me a full day easily and be at 30%. S21 should only be 25% less battery spec wise but sure doesn't seem like.
