Phone owned for more than a year

I have had this phone as a daily since January 2022, will be replacing the battery. Overall, I had an excellent experience with it. It feels so premium, solid frame, has got some weight to it (which is good for me), still good as a daily in 2024.

2021's best flagship is 2022's great option; what I think after one year of usage.

Phone owned for more than a year

I originally switched from iPhone to Samsung in 2020. I was getting bored of iPhones and thought I'd try the Galaxy S20+. That phone was awesome, so when I saw the trade-in values on the Samsung site, I had to get the Galaxy S21 Ultra.

To summarize this device; It's Ultra. Everything about it is what you'd expect, and more. I've never been consistently impressed with a phone, especially after the novelty wares off. It's also improved a lot since launch, from better camera processing and shutter speed, to longer battery life. Overall, what we have here is one of the greatest Galaxies, and one of the greatest phones avaliable.

Good but not worth the price tag.

Phone owned for less than a year

Been using this Samsung Galaxy S21 Ultra for 6 months and hace found its to be a good handset but just not worth the price tag. The phone is too large to use singlehandedly. I chose the Ultra over the plus for the upgraded camera. Six months in the camera has been somewhat disappointing. There's a S21+ in our household and the photos between them are not very different. The telephoto lenses on the ultra are a cool addition theoretically, but in use the super zoom is pretty unusable and grainy.
