Phone works great

Love the cameras and can really tell the difference with the display and it's variable refresh rate. This phone is blazing fast. Wish Samsung didn't remove MST, but other than that, this phone is about as close to perfect as you can get.

Samsung hits all the right notes for an excellence

[This review was collected as part of a promotion.] I purchased this back in February and had to actually wait a month for it to arrive. The wait was well worth it. I am very happy with this device. My previous device was a Galaxy S6 Edge, which was also excellent but was now fully worked it's life. I have had iPhones before as well as older Galaxy S4, Original Galaxy S and HTC smartphones previously. I have to admit this is one of Samsung's best effort yet. The camera is awesome, battery life is exceptional, beautiful screen and of course performance and software updates has bee. Surprisingly very good. My only feature that I miss and which could have been useful due to covid is the heart rate and blood oxygen sensors from older models. I mean the simple fix would be to get a smartwatch to do this so it's not a deal breaker. You wouldn't think of watching a movie on a device this small but your eyes will be in for a treat. As per usual Samsung's vivid AMOLED screens are the best in the industry. The battery life for a moderate user is easily two days. I rarely charge to full, just plugging in for a quick top up and I'm good until the next day. That being said, remember you have to buy your own super fast charger as it doesn't come in the box. Also you should note if getting a 3rd part charger you need to make sure it has the PPS feature for super fast charging to work. I learnt this the hard way :( Overall there is very little to no issues I have had with this device for the past 4 months. I am very impressed with the progress Samsung has made. The device is stable and performs near perfect each and Everytime. I would consider this a workhorse of a device this especially for business users. I look forward to many more years of great service. As a side note, this device supports UWB so if you have the Galaxy Buds Pro they pair seamlessly with it. It's an overall good user experience. As I finish my review I have to repeat that the camera is absolutely beautiful. The photo and video quality is amazing and you won't be disappointed. There is some slight lag however the latest software update has reduced this lag greatly. I'm sure features and performance will keep improving over time. Great job Samsung!

Overall pretty solid

Went from a OnePlus 8 Pro to the S21 ultra, overall I'm happy with the performance and screen. The battery life was a little worse than I expected but overall still very good. It has a weird quirk where when the phone is "moving" basically while you're walking, it will try to keep the cameras from moving so you don't hear it rattle. This in turn causes the battery to drain. If this was fixed then I'd be extremely happy.

Truly Ultra.

[This review was collected as part of a promotion.] I've had this phone since February 2021, and I upgraded from a Pixel 3a. The jump was incredibly significant. What stood out to me was this gorgeous screen. Since we spend so much time looking at our phones, why not have a great quality screen. The 120Hz made it a true game changer for me as well, I'll never go back to a 60hz phone ever again. Other aspects of the phone also wow'd me and made me appreciate Samsung's flagship this year. One UI is a pretty smooth experience, and I'm sure some polishing of the animations will just continue to improve the experience. It's battery has made me pretty happy as well, I have yet to charge it in the middle of the day, I usually end the day at 11pm with about 40% battery. The cameras are fine, what you expect from a high end phone, but I know the software can still make this a better camera to compete with a Pixel. I now have this paired with my buds+ and active 2! A wonderful little interaction within their devices. I think I'll continue to purchase the flagship when possible, unless they keep taking away features.

[This review was collected as part of a promotion.] I was an avid HTC person. I have had my 11 for years. It was starting to get hot so I knew the time had come. I was skeptical because of the bloat wear and how excessive it used to be. They have cut back a ton. The camera is to die for. Smooth operations, great battery, amazing graphics.
