  • Exceeds all Expectations
Color: Phantom Gray Size: 256GB Style: S21
Samsung hit the nail on the head with this one. This phone has everything I need and more. The camera is top notch. I find myself leaving my DSLR at home, unless for special occasions. The screen is super clear even in direct sunlight and collects very few fingerprints (its like sorcery). The screen refresh rate also lends itself well to make the phone feel snappy and smooth. It's honestly heaven in my hands. The fast charging is a must, but fast wireless charging is even better. In glass finger print sensor is fast and accurate, you just have to get used to where it is (way better than face ID. However, the battery life is a little short (for heavy loads), but fast charging more for makes up for it. I considered getting the Ultra, but this phone exceeded my expectations in every way. The law of diminishing returns plagues the Ultra waaay too much. Take it from a person who values fast, robust, and cutting-edge tech that the S21 5G will not leave you short handed at nearly half price. It's not the cheaper option, it's the smarter one. ... show more

  • Great phone with great functionality
Color: Phantom White Size: 128GB Style: S21
After a bit of researching for a phone and what I want to use it for, I decided to go with the Galaxy S21. It's on the higher specs for phone capabilities so if you want the basic functionality of a phone then this is not for you. The phone is very responsive along with the 5G capabilities. I really only bought this phone for the use of Dex. Everything else is the icing on the cake. I've had this phone for a few days and I enjoy it. There's really not much I can say that is bad. The ONLY thing that's "bad" is they DO NOT include a wall charger. All in all, a great phone made by a great company. ... show more

  • Very good Android deal
Color: Phantom Gray Size: 256GB Style: S21
Camera and picture handling is quite good, the 3 lens comb is great. It's not iPhone though... Sometimes camera is leggy, sometimes it doesn't fast enough. And people sometimes look pale. Night mode is great. Battery life is OK. Screen is great, even in the sun. The handset is light! Worst part is Samsung launcher (home screen app) since it doesn't let scroll down on app-drawer, and instead you have to go left-right browsing pages. Just bad design. Luckily, android let you change the launcher easily! ... show more

Color: Phantom Gray Size: 256GB Style: S21
It's taken me a little while to get used to. I am getting it. I miss the fact that I can't seem to make the widgets I need to put certain things in a grouping. Plus, I can use the same phone cover.

  • Gets the job done
Color: Phantom White Size: 128GB Style: S21
Brand new out of the box, no issues so far. I'm upgrading from a 2017 Samsung J7 V so this is a decent upgrade for me. Does the job, Loving it so far. Battery life is comparable to my old phone, not bad. Face recognition and finger print scanner is awesome in my opinion, fast and easy. Again,I'm coming from an old model phone so these perks are all new to me. I'd say that it's worth the money for sure. ... show more

  • What's not to like
Color: Phantom Gray Size: 256GB Style: S21
I just upgraded from a Galaxy 6 to this Samsung Galaxy S21 5G. I should start by saying, I am very pro Galaxy phones. Great features, excellent screen and a lot of bang for your money. I am certain I have more phone than I will use. Still, I like the ease of use. And, of course, the photos are so much better than my poor S-6. I made this move because the S-6 is the last phone Samsung will update. It won't belong before that stops. And, although 5G has barely rolled out, it will be nice the transition will smooth for me. ... show more

  • Sluggish and faulty-returned it
Color: Phantom Gray Size: 256GB Style: S21
This was hands down the worst phone I have ever purchased. I have been a Samsung user for years and loved every phone from galaxy s4 through to my previous galaxy note 8. The S21 was very sluggish with every action. It was as if it disconnected constantly from celluar and wifi and you had to wait 20 seconds or more for it to 'wake up' to do anything. Within weeks it began to malfunction and freeze up. I constantly kept having to restart in safe mode. I eventually had to erase all data and ultimately attempt several factory resets. After several tech calls with amazon repeating the same troubleshooting steps, the last resort was to take it to an authorized repair service 30 miles away from me. However after working with the repair service they said it likely needed the mother board replaced. The Amazon customer service said it was clear it was faulty and to return it...I would be fully refunded and then I could buy it again. Well they refunded me $100 less than I paid without explanation. When I inquired they claimed it had been returned outside the 30 day window and this was a restock fee. I am now protesting this as I spent hours and weeks trying to get the phone to work before returning it. Trust me....this phone has major glitch issues. I also advise you save your money and sanity and NEVER buy a high end product from AMAZON. I can accept that sometimes a product just is faulty but this issue was amplified by the Amazon customer service methods and refund policies. The headache and hassle I've been through has been exhausting. If you do order from them I suggest you save copies of the order details page and all chat history if you ever want your money back. I've asked my issue be escalted to a manager but in the meant time because of this fiasco I have had to buy a lesser phone as I'm out $100 not to mention the case, pop socket and screen protector i got for the S21 that is wasted now! :( ... show more
