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.

    I love it! The size is not too big and the colors are sharp and clean when taking pictures or video! I like the way you can zoom in close on something high up or far away and can crop pictures from a video! I have more storage now and love the colors you can buy! The price was very affordable too!

    Upgraded from a S10 to the S21. While the S10 has been a great phone, the S21 has already surpassed it in performance. The button rearrangement has taken some time to get used to. And the lack of SD slot is sort of a bummer, but other than that it's a much better phone.

    Great phone, but too many useless apps.

    This is probably the best phone I've ever owned, The only downside is my carrier which has preloaded the phone with useless apps that cannot be uninstalled. If you have the option of getting an unlocked version, which won't have these apps, I would recommend doing so.

    Bought this for my son who is 14. It was a tremendous upgrade from his previous phone. It works great, great camera and he had had no complaints. He is able to stream to our car's video screens which he absolutely loves!

    My daughter was going to buy a refurbished phone but I splurged and got her this one…needless to say she was happy. Transaction was smooth. Hone is sleek. Screen bright and camera wows. She loves it.

    I just got my phone last Saturday. So it's been a week. So far so good. I don't like the fingerprint login. I can never get it the print just right so I always end up using my password.

    Love the ease of access for this phone. It was a bit saddening to lose the SD card slot but as I have never maxed out the memory, it's fine with me to lose it.

    Aside from the salesperson, who didn't do anything i asked. My phone already is at 28% full after less than a week, my battery life is half a day. I had to buy a charging tap, phone doesn't have a headphone jack. I do not know how to delete any apps I don't need. My photos are in three different locations. I really need some physical help who wants to help.
