Proven winner
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love this phone. Battery life is still amazing after owning it for over a year and a half. Camera is hands down amazing. Makes iPhone users jealous with the zoom features. I don't want to upgrade it because it's still a awesome phone. Photos are of the of a cabin across the lake and half way up the mountain. You can't even see the cabin in the picture from the lake shore. It zooms in very far. I also use the zoom feature on this camera as a spotting scope at the gun range.

||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Nice phone. Fingerprint sensor not always working is an issue. My wife has same issue thiugh on her iphone 14 ultra. No rear sensor for AFIB and oxygen levels like my S8 did. A failure by Samsung here. Cameras are very good, 100x zoom allows me to take great pictures of the moon. Macro feature is also phenomenal. Battery lasts forever.

Galaxy S21 Ultra
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I wasn't exactly sure which type of phone to purchase when I first walked into Best Buy. I was deciding between the Google Pixel 5 and Samsung Galaxy S21. However, after talking more to the best buy associate, Taylor, I came to realize that the Galaxy S21 Ultra was tailored more for my needs. Thanks to Taylor, I realized that the Ultra existed and was capable of producing such high resolution photos, along with special features such as the director's view. That was enough to sale it for me. Although I was a little worried about how large the phone would be compared to my prior one, I do not regret the decision. Overall, I love the phone's capabilities and I'm so impressed by how well the photos turned out on my recent hike! I am so fortunate to have been helped out by Taylor in my phone selection process. Taylor was easy to talk to and provided exceptional customer service by going out of her way to answer all of my questions, as well as offer honest advice in my purchasing decision.

Indescribable.
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.So, have you been looking for a phone that actually DOES what you want, when you want? THIS is it, AND more. I've had it for a week, been playing around with it as much as I can, and it's STILL keeps revealing more stuff to play with. Unbelievably smooth, wonderful to hold, (even though I've now wrapped it with a USG protector), great to navigate around on. SO many camera options, SO many ease of access apps. I love it. The price is up there, but it's SO much more than I've ever had on my S8. It's extremely worth it, and I've only had it for about a week. Can't wait to get that camera out there, and earn it's keep!

Q: QuestionCan't activate galaxy s21 on cricket wireless or any company
Asked by Anonymous.
- A:Answer Having the same issue and I bought it unlocked from best buy?! My cricket sim would not even show up in the phone or a tmobile one. Or a brand new sim from cricket. The phone isn't on crickets list either because it's not 5G compatible allegedly. So I'm trying to figure this out. Exchanged the phone to see if it was a faulty phone. Literally so frustrating. What carrier can I switch to?
