    Samsung flagship. Expensive (though I got a 1/3 off deal, as it's last year's model and non-foldable) but top screen and camera in the industry. Great signal reception. Cons: no headphone jack, no expansion card slot, no charger block included, just a USB C to USB C cord. With continuous usage, battery lasts less than a day.

    Samsung Works Great As Expected

    Works great. I upgraded from an early 2018 Samsung A8+. This phone has newer features like multifreq wifi that gets 200-300Mbps down at home, it supports t-mobile call over wifi whenever in a building that is blocking 5G/LTE signal strength and has wifi. The newer OS has betterment's than my old cell, such as putting to deep sleep apps that I have installed, but rarely use, more features for the user in the newer OS. The only complaint is the lack of earphone jack. The charging is faster even than my old cell, which had fast charge. The price is also a bit steep to me, I was fortunate to find a Christmas special discount and got the last S21+ in house. The staff at best buy also was great, they worked out some issue getting the sim, they transferred using smart switch, which mostly got ever app, data and information.

    Love this phone. Alas I did have to have a replacement after maybe a year because the screen died. I am still using the replacement to date and will probably get a newer model and use this to replace my backup old flip phone.

    Upgraded from the S8 to this. It was a easy smooth transition. I really like the smart switch feature. Also the floating window feature. Battery life is really good and the camera is excellent.

    Maybe I waited a little too long to purchase me from smartphone. I had avoided the world of smart phones mostly due to the fact that I didn't want to deal with the things that I would have to deal with from work as long as I could honestly say "I do not have a smart phone". It has been an extensive learning curve and I still learn things about this phone every day. It's capabilities, clarity of photographs and the sheer convenience of all of the included apps, some of which I did not know existed. Previous to this for the only thing that I had been associated with was my android tablets, that are also Samsung and have performed beyond my expectations. I can only hope that this phone meets my expectations that I have grown to expect from Samsung products… Only the best!

    Battery life is amazing on this device, love the display and camera. Wish they would've kept the sd card slot but it's not a deal breaker for me. 120Hz display makes scrolling look and feel way more smoother than a 60hz panel.

    I love this phone except for one thing. Starting with the S21 Samsung has has removed the slot to expand the storage memory of the phone. I purchased this phone to replace a damaged Samsung S20 +. Transferring the data from my old phone to this one went very smoothly. I had no problems with overheating that others have mentioned.

    So, I really like Samsung and all, but I was disappointed with the Galaxy s21+ that I got; that is why I returned it. The design is good, and the camera was amazing! However, even though I know that Samsung used quality materials to make it, it kinda felt cheap to me. The main issue, and this is one of personal opinion, was the screen ratio. It seemed far to wide. I wish that the screen was thinner and taller. On a more positive note, I loved the High Refresh Rate!! It made it enjoyable to scroll down even the settings lol! However, since Samsung is starting to roll out higher refresh rates on their midrange phones, it seems like buying the A52 might be a better option.

    No, I would not recommend this to a friend

    Initially was reluctant to get the S21 plus (i had an old samsung & didn't want to change). The phone has been nothing but amazing. Smooth scrolling with 120 hz, excellent camera, 5G, very fast. Plus the battery is AMAZINGGGG sometimes i don't even charge it for days. Also the little features, make the phone so much more enjoyable to toy with. It's extremely adaptable holding up for work, gaming, my photography & socials. So happy I got this phone id definitely recommend & after having it for a year id say if need be i'd definitely buy again.
