    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.

    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.

    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.

    New Galaxy S21

    Had to replace my S6 so this S21 looked like a good option. As could be expected, there are dozens of steps required to replace all the missing contacts, etc from my S6. S6 took a swim which essentially destroyed the phone and of course, nothing was backed up. S21 might be a tad larger than the S6 but not enough to make a difference. Camera looks to be excellent, volume and reception on the phone is equally good. Everything else is still in the process of being re-generated.

    A fast phone and solid performer

    We upgraded several generations to this phone, so there is a learning curve with the newer interface, but it's still a pretty intuitive phone that works well. It's fast with great call clarity and solid construction. No glitches thus far in function after a few months of use. It holds a charge through a workday with frequent use (though not streaming or the like). The size is a good compromise between a large screen and carry-able phone.

    It is a good size. It does have a little trouble connecting to wi-fi signals sometimes; but other than that, it is a nice phone. It takes great pictures. Battery life could be better--has to be charged late in the day after being fully charged the night before.

    Bright, clear and large screen! Battery life so far has been great. Camera has lots of features too, but have not played around with it to much yet. Great experience with Best Buy transferring data, etc. from old phone to new one.

    Bought this phone to replace my mom's old Samsung. The size is not too big. Easy to transfer everything and use. Battery life is amazing. The photo quality is amazing. We could not be happier with the upgrade.

    I bought this new phone because the battery on my S-10 would no longer go a day without recharge. I could have skipped the S-21, it discharges just as fast even tho brand new. Otherwise, a fine phone. Its faster, sharper, a little bigger but not too big.

    Good phone, first one in a while. Not crazy about camera/video operation, but have only had a few weeks. Does not seem to be saving videos. Good size, a bit smaller than my last one which I actually like, easier to hold. A bit pricey, but they all are!

    I bought for my mom, she loves the phone . It is more durable than advertised, fast, huge screen of course and good amount of storage. Battery life is longer than expected, it easily can go a full day.

    Awesome phone for years now. Never lags. Only gripe is the battery but what do you expect with a screen like this.
