    Worthy upgrade from S9

    Owned for less than 1 week when reviewed.

    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 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 upgraded from Note 9. The Note 9 is the best phone ever made but it wasnt holding charge after havung it almost 4 years. The last update did it in. I bought the S21. At first i wasnt happy becaue the battery barely lasted a day with moderate use and there was heating issues. However, after the first update and the phone getting used to my use there is no longer a heating problem and i end the day with 50% battery left with moderate use. The audio is great. It's loud. The bottom speaker is louder than the top. The camera is great but Samsung's camera always had softness to it that i was never crazy about. I can't speak to gaming as i dont game. I do wish Samsung would include a charger. They include the cable but not a charger. No expandable storage. I dont like 5G. Verizon doesn't give an option to disable 5G but you can download a Band app that can disable it. The staff at Best Buy in Hartsdale are the best. They go above and beyond. Nice group of people.

    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.

    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.

    This turned out to be a huge update from my old friend, Galaxy S8. They have the same features but the S21 has a lot more. Now I spend a lot of time trying to figure it out. I was surprised that it didn't come with a complete charger but I can use my old charger with it and also our wireless charger.I realize I can learn about this phone on YouTube but I learn better with a good face to face teacher and hands on.

    So far, so good. I purchased this for my 14yr old daughter who really loved the color of it. She was a fan of the iPhone, but I decided against any of the kids using Iphones because of the inability to use apps like Bark on the Iphones. Also, I have kids plans through Verizon and it allows parents to add the allowed phone numbers to their child's phone to limit spam calls and unknown callers, limit internet access if needed (like at night when they are supposed to be asleep or during school hours), tracks location (which helped a TON when her phone was stolen), and many other helpful parental tools. The iPhone allowed them to remove the content filters from the Verizon app working properly. The android phones require a specific code that can't be bypassed unless they know the code. She hasn't complained about anything on it so far and seems to like it. Has a great camera!

    I have never had a phone that I liked more than this one. After 9 months and constant usage, the charge holds for over one day. And it came with the super fast charger so it recharges in less than an hour typically. The quality of the photos is better than any camera I've ever had, and I'm a senior so that's saying something.

    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.

    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.

    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.

    Needed to replace a broken Galaxy 8+. Wanted to stay with Samsung because I was comfortable with its operation and didn't want to scale a steep learning curve. Bought the base S21. 5G is a little bit of future proofing. Camera is just fine for casual usage. The transfer of data took a long time but for the most part went smoothly. There are enough differences so after a couple of weeks I'm still trying to groom it to behave like the old phone.

    My 5 year old phone would no longer hold a charge for the entire day. With the help of Ashley (Marina Store in CA), I was able to get all my questions answered and select a replacement device. I chose this phone based on our discussion AND highly rated Consumer Reports' review. I am happy with the phone AND the expert help & advice received from Ashley. She even helped my get the new phone set up and data transferred from my old device. I highly recommend her

    Nice new phone. Transfer of data took longer than I expected, but once it was completed, everything else has been smooth. The team at Best Buy was very patient and helpful. It is not the top of the line, but has enough bells and whistles for me.

    Upgraded from an S7, so the differences are huge. I like the extra security biometric options. The camera is great, The Smart Switch app for moving things from my old phone worked pretty well, but needed to be run 3 times to transfer to the new phone. Not all stored sounds transferred which is aggravating. I now have to install new ringtones and notification tones. Over all, it was worth the upgrade.

    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.

    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.
