    I am loving my new Samsung S21 device!!! This device takes beautiful pictures, runs fast, and has many little options not available on previous Samsung devices. Also very pleased to have not gotten the Samsung S21 Ultra because due to the size it fits perfectly into a back pocket even with it an oversized Otterbox. Buyer beware, does not come with charging port and it has changed from previous Samsung devices.

    I bought this phone over a year ago for my girlfriend, she had been using an extremely old galaxy. So old that it could barely load any apps, the browser and she needed it for her work. I knew this was going to be the gift I needed to give her, and knowing she uses it everyday and it’s so much faster and cleaner than her old one, makes me the happiest I could be!

    This phone is fast and intuitive. It's a nice size and weight as well. The camera quality is great. I'm a somewhat light user, but I haven't had any problems with it running too hot. The setup process was easy, and if you liked previous Galaxies, this one retains the best features of the series.

    I purchased this phone to replace an aging Samsung S7 phone. Staying within the Samsung family made it very easy to transfer my contacts, messages, texts, emails and more. The only downside was that the saved passwords did not transfer for the apps. I have had this phone for a little over a week and am still discovering new features. The greatest feature so far is the battery. I am on my second day since the last charge and I still have 59% battery life left. I should also point out that I get a stronger signal and am getting 5G where I live in rural Southern Wisconsin. I haven’t put the camera to a full test but I will in the coming days and weeks.

    I was skeptical about initially buyinv the phone because of the reviews with people saying it was overheating but i personally have had any issues. I will say since Samsung got rid of thd sd card slot i had to get use to naking sure everything was in the cloud orherwise youll use ALL your internal storage FAST

    Beautiful phone still haven't figured out all the features but I am a galaxy baby. I would've like 2 have the Ultra but 2 pricey. Overall looks good and feels good in my hands.I use supershieldz screen protector cost less than 10bucks its easy to apply works well no issues with fingerprinting or usage of the touch screen. Overall I am jn love with my phone look 2 have years of joy with this one especially since I have geek squad protection. I actually brought my galaxy s8 from best buy it still performs well.I upgraded due 2 5g changes and honestly I wanted a new phone. The speed of this s21 is great no lacking really the only downfalls are there's no option for adding a sd card having 2 which up on charging a block the phone didn't offer stylish pen or come with a charging block and no earbuds that we are use to with these galaxy phones. I truly think 4 the prices of these phones and samsung eliminating the sd option we should've gotten the stylist pen cord and charging block and earbuds...besides that I am happy with my purchase.

    Great phone for $750 and I have no complaints. I only use the phone for basic functions like surfing the internet, taking basic pictures, shopping, texting, etc. ... there isn't much to dislike other than it is a bit bigger than my previous S8 (I like phones on the smaller side).

    I was looking to upgrade my Samsung S9 to a more advance S Series. Caught an awesome sale going on during the holidays with unlocked phones. After owning this phone for almost 8 months decided to do a review. The features I like about the S21 are: 1) Picture Quality 2) Battery life is pretty good 3) Storage Space is 128 GB (however, wish MicroSD card slot was available for expansion) 4)Scratch Resistant Glass 5) Connects to Bluetooth devices quickly. 6) Can have quite a few apps running at once. 7) Can work on documents on my online drive. (Love this feature) 8) Can play all sorts of games on the phone. Cons: 1) I'm old school and love the ability to connect headphones to my cell phone with the port. 2) Miss when the phones automatically came with earbuds and other accessories. Overall great phone. I would recommend this phone to others and be sure to purchase a screen protector and case for your phone. This is an investment.

    Bought this phone for my wife to replace her note 8. She is so happy to have a purple phone but one that is also faster, lighter, and doesn't have a game burnt into her screen. I recommend this phone not just because its purple but because it was in expensive compared to upgrading through Verizon.
