    Excellent performance from my Samsung Galaxy S21+! The camera on it is our family's "go to" for the clearest and sharpest photo moments.

    Great phone, long battery, fantastic camera, beautiful screen. Only cons: no headphone jack nor expandablememory. Samsung did not need to follow in Apple's footsteps.

    This was an upgrade from my S7 and yes that S7 lasted me 4+ years! And yes, my old phone still works, but the camera, for some weird reason, stopped working so I decided to purchase a new phone. I do like Samsung phones, never had a problem with them, their cameras are superb. The S21 so far, has been easy to use, slightly longer screen but not bulky. It's a great phone. Because i upgraded from an older phone, i had to separately buy charging cords which are completely different from my old S7. I highly recommend the S21 5G, it's a nice, efficient phone.

    This was an upgrade from the Galaxy S9+ and my hubby is very happy with his new phone. It's fast, has double the storage of the old phone, the battery lasts longer. Although we don't live in a 5G area, we're ready. There are lots of options to customize the setup. The data transferred seamlessly from the old phone. Although we don't live in a 5G area, we're ready.

    I got this phone for my wife because her other android device was giving up on her. She is not into apple so I got her this Samsung and she LOVES IT. I mean the camera and the 128 GB memory? like why not? The phone is fast, the screen is great and battery life is awesome. Again it depends on usage but she can't get enough of it.

    So far I love this phone. It is light weight, the pictures are very clear. My only problem is not have an SD memory card, but as long as I can copy my pictures over to my computer I am happy. I am not into gaming so this is the reason I purchased the less expensive model.

    This review is written after 2.5 year of ownership. I really haven't noticed any problems. Battery life seems good, charging port is is good shape. No cracks or chips in the screen though there are so scratches in the bezel where the case doesn't cover it

    Super Samsung Smartphone

    Just the right size for viewing everything. The phone is light, bright screen, fast boot and shut down, and the battery lasts at least a full day of emails, web searches, and mostly idle time when I have the phone ON for at least 12 hours. I mostly use the phone only when not at home. Only when on a vacation do I have a phone on 24/7, bu haven’t been on a vacation in a year-and-a-half. Can’t wait to get back on the road and use this wonderful phone — which is the BEST smartphone I have owned, and this is my fifth one. I usually keep a phone for 2-3 years before upgrading. Samsung now provides four years of updates, which was a major reason for my buying this phone — along with all the positive expert reviews.

    Love this phone. Finally traded up from a Galaxy 7, (I know, I hate change and phone payments). Anyway, my old phone was just like me, slow moving. So, I am hoping for a change, meaning I am hoping that I will become more like my new phone, faster, sleek and beautiful. So far, no disappointments. I get great service in locations I did not get service in before. It is fast and easy to use.

    I've had the S21 for about a week...enough time to form some opinions after upgrading from my S7. It's a screamer. Apps run so much faster, it's incredible. I'm not sure whether it's the 8GB of memory or the chipset, but it's noticeable. The camera is awesome. The display is impressive as is the color depth. Battery life is fine for my use. On the downside, I miss the LED indicator horribly for unacknowledged alerts, the heart monitor, the headset jack, the absence of a card slot and the fact that GPS altitude is for some reason not recorded in the exif data on my photos. The edges of the phone are slick, and you'll definitely want a TPU sleeve to reduce the risk of dropping it. Nonetheless, I'd buy this phone again in a minute, and highly recommend it. Samsung has done a good job with the S21.

    Worthy upgrade from S9

    This was an upgrade from my Galaxy S9. I was hesitant to do the upgrade because the S9 had good specs, like more pixels per inch than the S21 and a Gorilla Glass back versus plastic on the S21. But having made the switch it's a real improvement all around. When using a case the back material is irrelevant, and regardless what the tech specs say on paper the S21 display overalljust seems better. One feature I used a lot on the S9 was the rear fingerprint sensor. The on-screen sensor on the S21 is better though. The phone looks better in person than in photos, it's not as quirky looking as I thought it might with the 3 lenses on back.

    I purchased this phone to replace 3 year old LG v30 that was starting to act weird, was losing battery life, and had dated cameras. That said, really the two thing better about this phone is its cameras and faster processor. The battery life only a little better despite its larger battery pack. I used to go 2 solid days on a charge on my V30 with normal use. I find myself leaving power saver on most of the time and with light use could make two days. Pretty disappointing when the v30 would go 4 or more days with light use when new. Then there's the software. So much Samsung bloatware, much of which can't be disabled or easily removed. Going through the apps and looking at battery usage, it appears these are eating about 20% of my charge for apps I don't use, nor want. If it wasn't for the incredible trade in value that I received for my old phone (which I had to spend a few hours on the phone with Verizon to actually get applied), I would have returned this phone.

    No, I would not recommend this to a friend

    Very pleased with the S21 5G! Would rate 4.5 stars if that was an option. Size is very good for me, Camera is amazing. Would rate 5 stars but optical recognition isn't as effective as I anticipated. 5g is worth the upgrade if you live in a 5g wide band area.

    I love my new phone so far. It works great. HOWEVER, I didn't like that it didn't come with a charger cord. I had upgraded from a samsung galaxy s7 and they had changed the charger type on the newer version. I had to run to the store for a wall charger cord before I could even start activating the new phone. THEN i realized I also need another cord to charge in my car...ok, got the new charger cords, thought all was well and realized when my bluetooth wireless headphones battery needed charged the samsung didn't put a headphone jack in the phone??? I had to order an adapter. MAYBE now I am done buying accessories for this I didn't realize i would need...Didn't like that, but I love my new phone otherwise.

    I was looking for a Samsung phone (my previous phone was S6 Edge) that's not too big. I don't like these newer phones that rival notepads for size. I like the shape, design and features of this phone. The cameras are great! Have run into some issues few weeks ago. The phone would just restart frequently, sometime while I was in the middle of working on it. I think this was a software issue which seem to be gone now. It was really annoying for a couple of weeks though. The battery life is great on this phone, typical of Samsung phones I believe. Overall, happy with this purchase.
