I love this phone and no issues so far. I had a Note 5 but it was time to get a more currant one. It was a toss up between another Note and this one. The only negative for me is I wish it had a media card slot but my Note 5 didn't either so I still have to Smart Switch as I don't do the cloud storage. This phone takes beautiful pictures and I'm still learning everything it can do. I hope its as reliable as my other phone.

when you buy a flagship product, regardless of the manufacturer, you get all the bells and whistles. 1:camera is proper and user-friendly.2: s-pen..is a bit of hype but the programs are solid and useful.3: battery life is solid with minimal heating issues.4:only issue is where did i leave it. senior tattoos and memory loss may not be improved by using the phone.

This phone is amazing, the camera is fantastic and the up to 100x digital zoom makes getting those further away photos a breeze. I upgraded from a Galaxy S9+ and I'm glad I was able to buy this phone. Only thing I don't like is that it doesn't come with an SD card slot for expanded memory. Other than that it's perfect. (To me)

Just got this guy not too long ago and there are many pros to this phone but also some very annoying cons
Pros: great cameras, good battery life, can effortlessly multitask.
Cons: the under screen finger print censor is very picky with the type of screen protector:
A soft screen protector is easy to scratch but works with the finger print
A typical glass screen protector is more scratch resistant but dont work well with the finger print
I finally have to go for the liquid adhesive screen protector
Oh, and it's expensive af

Not bad, camera is great of course, but the OS I am already having problems with it and I baby my phone, never dropped, or got it wet, and it just freezes up more frequently now than when I 1st bought it, and nothing I can do to unfreeze it, sometimes I can't even power it off to restart it. I still have my note 8 that has fewer problems, not only that almost all of my live screensavers that I purchased for my note 8, none of them work, they just crash.

Wow. I decided to switch ecosystems from IOS, to Android. Coming from Iphone 12 and ipad pro, I could not be more happy with the switch to the s21 ultra. Super fast, camera looks great, the screen is incredible. Wish I would have switched sooner.

I am Samsung customer for 4 phones. This phone boasts a fantastic camera and it's true. It takes practice and reading the options, but the results match SLR quality. Te trade in eased the cost,so it was good buy. Battery lasts longer than the S10+5G. I am a Samsung patron in an orchard of Apples!

Hands down, without a doubt, the best phone on the market. Extremely intuitive design and interface as well as powerful processing and camera capabilities make this phone unrivaled.. but all that comes at the cost of a pretty penny. GET A SCREEN PROTECTOR. The glass scratches really easily, I left mine in my pocket with my keys for 2 minutes and got 2 scratches on the screen.

To dive right into it , yes the s21 ultra is very very expensive. Plus at the price point it should probably start with 256gb as samsung did a few years prior with the note `10 plus. Money aside though, the s21 ultra is the best all around android phone you can buy , maybe even best smartphone period. The camera system is the most versatile on a phone yet, the zoom is ridiculous but surprisingly good much improved over the terrble 20 ultra from previous generation. The still phots trade blows with the best that the iphone and google pixel has to offer. Plus love or hate samsung's one ui software it is chock full of features and customizations that no other phone offers . If you want to take notes the phone supports a premium stylus in the s pen,want to use the phone as full blown pc in a pinch? fine just fire up samsung dex and youre off to the faces. One thing thats often overlooked is that Samsung has built an ecosystem that almost rivals apple with its galaxy phones , watches, tabs , earbuds and even PC. All of which flow together nicely albeit not quite nice as apple. Price aside there is no other android phone that ticks every box like the s21 ultra does , Just be ready to pay up and also deal with a pretty large device.

This is the best phone I have owned to date. It has all the battery life that I need and it has awesome cameras. Sure it costs a lot but you get what you pay for. The only downside is certain apps sometimee have some issues but they're usually fixed pretty quick. Im taking a star off for that becausw sometimes you do have to find work arounds. But when it comes to the hardware and operating system software in general its pretty good.
