    I have had this phone for a while now. I use my phone a lot both for business and pleasure. I rarely have to worry about not making it through the day as the battery life is great.

    This phone is great! I purchased primarily for the camera and so far I am very impressed. The kind of product I've come to expect from Samsung.

    This phone is really great, the camera looked like the iphone or even better. The internet is more faster and great memory space.

    I could not stand my iPhone. I was sold on the pixel 6, but the pixel has not released yet. I decided to purchase the S21 Ultra to hold me over. I do not regret my purchase. I have more control over my device and I am not forced to use apple products or services. You can customize your phone which is a plus.

    The phone is great. However, I came to the conclusion that phone got too big in recent years. I would love to have an option to get a smaller phone from Samsung.

    By far the best phone released at the moment. Super quick. Excellent camera. Even with high usage the battery still has plenty left at the end of the day.

    I purchased a Samsung Galaxy a21, unlock and used with any carrier. When I arrive home the phone was T-Mobile and had to spend the extra time to return the phone and get it replaced with an unlocked version that will work with my carrier. My carrier was not T-Mobile but the phone that I purchased originally was not unlocked. After returning the phone the only Samsung Galaxy 21 they had in stock was a used one returned and overlook buy geek squad. I ended up purchasing that one for a cheaper rate and so far the phone has been great and works as it should.
