    Amazing phone, super fast and beautiful display. The cameras work wonders and produce beautiful images up to 30x, any more than that and I wouldn't use the zoom personally. The videos look crystal clear on it as well. I also love how there are speakers on the top and bottom of the phone now so I can hear from both sides as I'm watching a video

    Pros: Camera. Screen. Processing speed. Battery. Price(200 hundred dollars cheaper than previous model). Bulky but still has this slick Look. Got an additional discount from Sprint. Cons: No traditional headphone jack. Cutting corners to make it cheaper. Does not have a charger that comes with the box. No more micro USB slot for additional memory. I got the 128 gig and now I am struggling with phone memory. Samsung Galaxies are prone to screen burn .(crossfinger this one does not) Still a decent buy and even though 2021 has just started it can already be considered as an android phone to beat this year.

    Best Phone Out!

    Best phone I have ever had! This phone is unbelievably amazing, I never used my phone so much. I've had galaxy phones ever since the S6 Edge, and by far this is something I never expected. The camera quality is by far way better then any phone on the market, the 5 lens rear camera makes phone look amazing for far away and it has the ability to zoom in close to the moon and you clearly can see the craters. It comes with amazing apps that let you draw cool stuff if you have the sylist and much much more. And the best part I use my phone constantly and the batter lasts me all day or half way into the next day. I recommend this phone for anyone who wants great features and the freedom to customize your phone to your liking.

    Got to pay the cost to be the boss. Samsung paid that cost because this phone is fantastic. Coming from Ios, I was a bit nervous but I can gladly say that this is better an every way. I never knew how limited I O S was until I got this android phone. 10 stars! Would absolutely recommend this product!

    Wow, I love this phone. I was not really in the market for a new phone but a friend of ours had the S20 and the camera option was amazing, so I went in to look at it and yep I caved in. The phone quality is outstanding. Speed, operation, looks, etc, on point! The camera is amazing!!

    This phone is exactly what I was looking for and hoping that it would be. I take thousands of photos and the camera and multiple lenses was what sold me on this model. I was truly impressed by the different lenses that are used to get the best shot and how easy it was. Pictures come out beautifully. Zoom lenses and nighttime lenses are awesome. Of course the screen quality is a big factor in all of this and it's great. I'm so glad I waited for this particular model. I know this is supposed to be about the product but the salesman was excellent,

    Love the new phone. Hefty at about a half pound but feature full. Camera is insanely nice. Screen is bright, crisp, and clear. Slightly bigger then the S10 + which puts the biometric fingerprint sensor a touch higher. Different for those with smaller hands. My only complaint is the print sensor operation could stand to be improved. Even after enrolling 4 prints, I often have to use facial recognition or PIN to unlock the phone.

    Love the phone. Runs smooth. Cameras are awesome! Love the wide screen angle and the ability to zoom in really close! Only issue I have is they ditched the expandable storage. Onboard storage is acceptable so may not need extra storage.
