    This phone is amazing. The extra internal space is so useful, I'm so glad I can download apps now without worrying about having little to no room on my phone. The camera steals the show, although the night mode is not as impressive as some people make it out to be. I find that photos taken with night mode have a high amount of visual noise that detracts from the image quality: this is not an issue exclusive to Android phones. During the day or with night mode off, my S21 takes amazing pictures. I am pretty rough with this model, but with an Otterbox case of any kind, it will not crack from regular drops. I haven't noticed many scratches on the display either.

    Fast, responsive with great screen and camera. The plastic back is a downside, particularly if you use it without a case, but since I don't, I don't notice it.

    I absolutely love my S21! I upgraded from the S8 Note. The phone has worked amazing with no issues and the camera is one of the best qualities I've seen in a phone. Be aware though that it does not come with a charging base, just the cord. Base will have to purchased seperately. It also doesnt have a headphone jack or slot for an SD card.

    Liked the color so much but realized screen size was way too small for me. Always owned bigger phones, note 20 ultra was my last phone. Ended up getting a Samsung s21 ultra. Way better!
