    I absolutely love my new Samsung galaxy S21. It is the best phone that I have ever had. Super fast. Amazing pictures and videos. Amazingly sharp screen. I traded up from the Samsung galaxy S9 that I never thought I would get rid of, and I am glad I did.

    Good introduction price. Excellent quality, well is Samsung. Nice rear camera new design. But I liked more my Galaxy S20 FE that I gave in trade in.

    I love it, best purchase I have ever done, this phone meets all of my expectations and then some, I had been eyeing this phone down since it had come out and I'm so glad that I got this phone after debating on buying it for 20 minutes

    Solid phone ugraded from iphone 10s to samsung galaxy s20 to now s21. The s21 feels and operates smoothier then s20. Miss the iphone keyboard for texting and typing. The iphone screen does not touch the 120hz refresh rate of new galaxy phones.

    Love my new phone replaced a Galaxy S7 that I had for years. Good little solid unit I wish the time would show on the main screen all the time I miss that but other than that it's as good as my old one

    Great phone. Love the feature of directors view when recording videos. However, was sad when i noticed that there is no jack to plug in headphones. Not a fan of wireless buds/ headphones due to having to charge another item.

    One of the best S series so far. The s21 has amazing features and the quality of the screen and the refresh rate at 120hz is very crisp and clean. Has to be my favorite feature

    The Victus glass is no joke, can't believe the drops this thing has absorbed without a crack. Love the size, resolution and responsiveness is awesome, but the camera controls could be improved.

    Samsung has a good name. Pricey, but reliable. Performs as expected. Most features are standard across all phones. Hatebthe fingerprint reader being in the face of the phone. Hard to get it to recognize sometimes.
