Great camera

[This review was collected as part of a promotion.] I upgraded from a note 10 which I love, still this phone has not disappointed, so far maybe the only think is the pen not been inside the phone but with the case that has the pen holster built in, has worked fine so far.
I would recommend this to a friend!

liked the s7 better

Posted by: my review of S21
from Boston, MA
Expertise:Intermediate
The Google speech texts text is not as good as it was on the S7 the Bixby was actually worse I have had the phone for a month now And I'm still having issues with the speech text I spend more time editing than if I had just typed it out. Other issues are the volume control, they need some kind of lock, it'
I'm constantly turning it up. next I'm getting too many advertisements Notifications on the lock screen from Samsung, that they don't let you turn off. The last issue is the size itself, the phones are starting to to get too big, if I want a larger screen I'll buy a tablet. I am in Construction and in my back pocket. I feel like I'm going to snap it
No, I would not recommend this to a friend.

I have had this phone since it came out and would be lost without it. I literally use it for everything and it never leaves my hand. This phone is fast and powerful enough for me to do anything I need.

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.
I would recommend this to a friend!

Samsung hits all the right notes for an excellence
on June 29, 2021

[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!
I would recommend this to a friend!
