Best Phone I've Ever Owned
It's hard to know where to really begin with reviewing this phone, because everything about it is simply amazing! But here goes: Build Quality & Design: So I was at first a bit apprehensive about the curved display because I wasn't sure how I would feel about it (every other phone I've had had a flat display), but the curve is subtle enough that it's very easy to get used to and actually adds a bit to the ergonomics of the design. The color looks just as stunning in person as it does in photos and the overall design of the phone looks incredible. The phone feels sturdy and the buttons have a very satisfying click to them and the fingerprint sensor has a great placement and works wonderfully. Display: The 1440p, 120Hz, display on this phone lives up to its reputation of being the best display you can get on a smartphone in 2021. The colors are vibrant and punchy, the clarity is top-notch, the high refresh rate (variable) really makes the phone feel snappy and quick. The touch sensitivity is also great and never feels like I have to put too much effort into moving around the UI. UI: I was a bit apprehensive of One UI as I hadn't used a Samsung phone since the Galaxy S4 (and the days of the old TouchWiz) and I have been using Pixel/Nexus phones for the last 6 years. I have been pleasantly surprised, though, by how much it retains the core functionalities of stock Android while adding in features that are actually more useful than I would have guessed they would be (having Google One feed to the left of the homescreen is a great addition by Samsung). From the ease of connecting Samsung peripherals (I have Galaxy Buds+ and a Galaxy Watch 3) to the extended screenshot feature to the baked in screen record and everything in between, Samsung has really matured in their UI to now offer a lot of useful add ons while limiting the unnecessary bloat. Battery: This is the first phone I've had where I really can feel confident that my battery is going to last me the full day if I'm going to be out and about and away from the charger. Even with full 1440p and 120Hz enabled, I'm easily able to achieve 5 to 6 hours of screen on time with roughly 20 to 24 hours of total battery endurance. On days that I don't push the phone as hard, I can get up to 8 or even 9 hours of screen on time and up to 2 days of overall battery endurance. Only on days that I'm scrolling through videos on TikTok, taking a lot of photos and videos, and really just having the screen on all day do I need to charge it even a little before the day is up (and even then getting it to even 50% is enough to give me confidence for hours). Camera: My last phone was a Google Pixel 3XL which, at the time, was basically the leading smartphone camera and could produce amazing shots every time. I wouldn't say that this camera is as consistently and easily good, but the potential for great shots is even greater with this phone. Occasionally I have to take a few different shots to get the one that I want, but when I get what I want, it looks incredible. And this applies to all of the cameras, which brings me to the second point ... The variety of cameras here makes the experience wonderful. I'll frequently take 3 or 4 different shots utilizing all of the cameras to gain different perspectives and image profiles and nearly every time I get impressive photos from every lens (yes, even the 10x zoom camera can pull off pretty stunning imagery). The camera is definitely a high point for this camera, but you do need to be willing to work with it a bit more than you would on a Pixel or iPhone which are better quick point and shoot cameras, but lack some of the diversity of use that you can get with the Galaxy S21 Ultra. Conclusion: Overall, this phone is just incredible from top to bottom and is by far the best phone that I've ever owned. I would recommend this to anyone that is willing to pay a bit more for a premium device. ... show more

Best Galaxy phone I have ever owned!
Color: Phantom Black Memory Storage Capacity: 128 GB
I switched from a Samsung Galaxy S8+ that I owned since 2017, and boy can I appreciate the upgrade! The phone is super fast, with great visuals and an abundance of features. Some of my favorite features include the Wireless power sharing, DeX (turning your phone into a computer with a tv or pc monitor), live caption (especially when I have to keep my phone on silent and want to watch something) and the amazing cameras, just to name a few. In regards to the cameras, the selfie camera is clean with great quality and the 100x zoom feature is in a league of its own. I will admit that going all the way to 100x zoom for pics will not give you best quality, but even at 20x zoom, it is amazing how this camera can behave like binoculars and pick up objects without any issues and maintain good clarity. The battery life is also quite amazing! I had to charge my s8+ 2-3 times a day with heavy usage, but I can easily go a day and a half with this bad boy. One negative I will say is that the phone does not come with a charger, which can be annoying if you don't already have any existing charger on hand. In my opinion, to preserve the quality of the battery, Samsung should have included a charger that was made for the phone, to prevent persons from possibly sourcing 3rd party chargers that may not be the best for this particular phone. On another note, I know some individuals are unhappy about the expandable storage not being a feature anymore, but as an S8+ user I never used expandable storage and will not miss it. With cloud storage and other ways to upload and store your data, it is not that big of a deal in my opinion. I can go on and on about this phone but I'll just conclude by saying that I am extremely happy with my purchase. Great job Samsung! ... show more

So after having this phone for a while now..
I have to say, it is the best phone I ever owned and it's simply amazing. I never thought I'd pay this much for a phone, and I don't think I ever will, even if this stops working or breaks. But for what you get, this is probably the best damn phone you'll ever get. If you're a smart person who prefers androids over iphones (just like you'd prefer a PC over a mac, exactly the same comparison) then this is the best one out there. Get it. I've read through other reviews here and I felt like there were too many weird or dumb complaints. I'm keeping it real here. The phone itself is fantastic. There is no problems loading anything, it's super fast. If you like games it'll run anything. The camera is as good as you could possibly need it. The only problem I have with this phone is that I have to restart it quite a bit, and that would be very annoying but it restarts very fast. The reason why I restart is because whenever I move to a location, the connection will become unstable/slow. But if you go into settings, turn off mobile data, then restart, then turn it back on and turn mobile data back on, the connection will work fine again. It's stupid, it's annoying, I'm using At&t gophone prepaid, so you either have this problem or maybe you don't. Like I said this thing restarts very fast. Sometimes I turn off mobile data for 30 seconds instead/airplane mode, but in the end restarting/turning off mobile data works for me. I'm not entirely sure what the cause of this is, but I don't really remember having this problem with other phones. ... show more

No issues to be reported.
This phone routinely goes on sale on Amazon but a couple of reviews mentioning things like damaged goods on arrival, the phone not being unlocked for all providers, or even the phone having bootleg software installed on it nearly scared me off. Fortunately, when I got my phone, it was in brand new condition and was in fact able to be used with my provider (AT&T). One popular review mentions the phone came with bootleg software installed as the startup screen simply says Samsung without the model name beneath it in addition to having the Android mascot appear at the bottom. As it turns out, this is in fact just the regular startup screen of the phone, a fact that I looked up multiple videos of because I was scared when my phone had that same startup screen. The battery life is very good, dropping maybe 10% or less overnight with multiple applications open in the background compared to the 40-50% my S7 would drop overnight. This phone is also incredibly fast; nearly every app or web page I pull up loads instantly, which was again a huge shock after upgrading from my S7. Speed tests indicate that the 5G capabilities of this phone also work very well. The fingerprint reader is excellent, taking only one press most of the time and very rarely requiring two (even with a screen protector as well, although I do not use a tempered glass screen protector, so I cannot speak for how well it works with one of those). Overall this is a phone I highly recommend buying if you haven't upgraded in a few years and if you can get it on sale. In the past month I've seen it go on sale for $999.99 twice and it was even $924.99 on Prime Day. Just make sure to not cheap out on a case and screen protector as well. ... show more

For the cost, could've been better
Color: Phantom Black Memory Storage Capacity: 128 GB
So I spent nearly 3 weeks reviewing the Note 20 ultra this phone and the S22 Ultra comparing everything I could watching videos ect. I ultimately went with this over the S22 just because there was a lot of complaints with the S22. I've had this phone for just over a month now, and my first impressions on it are somewhat lower than I was hoping for. All of my feelings toward the s21 Ultra are based off of my prior experience with the Note 10+ which I switched over from after I cracked the screen. I figured 2.5 years was a damn good run for it. The Bad: So to start things off I noticed right out of the starting gate that he battery life isn't quite as good as my Note 10's was and it tends to get a little hot, however it's not horrible I still average a day to a day and a half if I let it go all the way dead. Next thing I was a little sad to see the micro sd slot removed, as I've liked having a removable memory card for backing up stuff just incase. I strongly feel not including a charging block is just a cash grab, but we won't get into that lol. The finger print reader was something a lot of video breakdowns raved about, however I feel its pretty bad. I only have my thumbs set for all 4 scans and more times than not it still can't pick it up. Size is somewhat bulkier, primarily due to the raised camera overlay, which results in the case being somewhat bulkier. Again not horrible but the Note 10+ was just so much slimmer and more comfortable in the hand. Lastly the cost. I bought my Note directly from Samsung for $700 brand new with a pair of galaxy buds and a charger included, so at $1200 this phone should have outperformed my 2.5 year old Note across the board, but to be quite honest its mediocre at best. The Good: So even with all the ranting there is some good with this phone. To start things off the camera has some nice new features. The fact that you can zoom in 100x is pretty impressive, even though at that distance any picture looks like it was taken with a potato. The camera also has a laser auto focus which is pretty interesting to watch in video, the camera will literally adjust to movement without you actually moving. You can notice some slight rendoring differences comparing to the Note 10+ but nothing crazy. Pretty much the only key differences is the Laser Focus and the higher zoom and telephoto capabilities. Next I can say the overall functionality is almost Identical to the Note 10+ aside from slightly faster operating when it's in 120 hz, so you will notice slightly faster touch response at times. Last but not least the memory on this thing is pretty much on par with the Note 10, both feature a 12gb chip of RAM which is just ridiculous for a phone, so with good internet connection both phones can run videos or games with ease. Conclusion: To be honest the phone is nice, I can't say it isn't. It does everything I'd need it to do and a bit more. However when comparing it to my old phone that had a hard 2.5 years of life filled with dusty environments and plenty of drops, it still averaged a full day of battery and fairly decent operation speeds and functions. I just don't know If I could recommend this phone, if you have an older generation Note (9,10,20) I would honestly probably say to save your money. However If you are in the same boat as I was and need to upgrade due to it being damaged it isn't a bad phone to go with. That being said I'd almost say it's worth looking into just having your current phone repaired. All in all the phones good, It suites my needs, but it seems more like an Android Iphone with everything it lacks at this point. I hope maybe Samsung will can make some better improvements in future models, but I guess only time will tell. I'd say I've rambled enough though, thanks for reading hopefully my input can help someone make a decision on which way to go. ... show more

Very useful in 2022.
Color: Phantom Black Memory Storage Capacity: 128 GB
Going into the process of buying a new phone, I was very skeptical about buying it on Amazon because you never know what you'll really get. I took the risk and bought it. Once it was delivered, it wasn't damaged at all and appeared brand new as listed. BATTERY: this phone really has a giant battery that can last you up an entire day, possibly two days if you're not a heavy user. DISPLAY: the screen looks so damn beautiful and the fact that you have the options to switch between FHD+ at 90hz and QHD+ at 120hz is so cool. The colors are vibrant as well. FINGERPRINT: Very responsive, though it will take some time for you to remember where it is on the phone. CAMERA: I love the amount of options you have at your disposal when taking videos and photos. From Night Mode to Director's View, there's so much to take advantage of to make your videos and photos look amazing. BUILD: The build quality looks and feels premium, though the matte back can cause your phone to be very slippery. Strongly recommend getting a case. VERDICT: The Galaxy S21 Ultra is such an incredible phone that packs so much for you to take advantage of. It's a phone that has gotten better as time passed and that's due to Samsung releasing software updates. I would absolutely recommend picking up this phone, even though the S22 series is arriving very soon at the time this review will be posted. Whether you choose to purchase this on Amazon or your specific phone carrier or wherever is entirely up to you. You won't be disappointed with what the S21 Ultra can offer you. ... show more

bloatware drives me crazy
Color: Phantom Silver Memory Storage Capacity: 128 GB
Samsung is famous for bloatware and their new flagship phone has more than any other phone they make. I like the new phone but the display scratches easily and Samsung’s bloatware is overwhelming. I turned off all notices, alarms, reminders, and notifications and still I am bothered at least once or twice a day by some notification for something I don’t want. It’s very troublesome and distracting. The first S21 Ultra I received had a scratched display and emitted warnings that the storage was full--although it was brand new. I received another one and within a month the screen had two scratches even though I only kept it in my empty pocket. I’d like to write about the great features and performance (it’s faster than my PC and the camera is out of this world!) but the bloatware is very troubling and bothersome. The notifications are annoying and disruptive. The user is forced into the Samsung world and it’s difficult to stay in the Google world that I prefer. Right off the bat Samsung downloaded 12 Samsung apps that I have no idea what they are for or any use for--just more bloatware. I had a support question and phoned their support line but had a difficult time understanding the tech because of her accent and the echo. I’m usually not bothered by accents, but this woman’s accent was impossible to understand. I was forced to hang up and phone another tech for help. ... show more

S21 Ultra, recommendation for all
I upgraded from the Galaxy s8 to the S21 Ultra with 256 gb of storage and 12gb of ram. I will start off by saying go with the Ultra or the base, you pay $200 extra for half an inch of screen on the plus (this is called decoy price, you see this at movies where the popcorn medium is only 1 dollar less than the large, but is 3 more than the small, so you might as well go large.) I'll give more detial at the end. Camera is super high quality, zoom is incredible. Front camera even takes good pics (I mean I looked good, so should you) Processor is as advertised, insanely fast, even at the standard limited benchmark (there is an enhanced processing mode to take away cpu 70% limit). Desktop mode is great, this phone is almost as fast in Dex as my actual Acer laptop. Battery life is phenomenal, can get 2 full days out of 1 charge if you use the phone less than 4 or 5 hours a day at 1080p res. 1440p, super clear and one of the bargaining point for the Ultra over the base. The refresh rate of 120 hz is incredible, I spent the first 10 minutes just swiping on the phone in awe of this. The ultra is also the only version with the curved screen,, the s21 and plus have flat screens.. This phone does an excellent job of cooling, even witha case on. (FYI heat causes the major wear and tear on the internal components like the cpu, so better cooling means better lifespan and performance). Customizable routines allow you to add features to your phone, from automatically silencing when you show up to work or school, automatically going into power save mode at certain times like when you are asleep, or even for when you turn on your Bluetooth headphones your phone can automatically switch to 1440p resolution and turn Dolby atmos on movie mode sound. Dozens of scenarios or time stamps for each feature. If you are the friend that walks on the grass, don't worry about bringing that bulky charger for when your friends' phones are about to die, this phone can wireless charge other devices (will stop charging when the phone drops to 30% minimum). If you are concerned about no color options, just remember, I had that beautiful orchid gray s8, and who got to see it? Nobody, because it was hidden behind a lovely teal case for 4 years. If the fact that Samsung dropped their charging from the 45w of the s20 series to a 25w for the s21, rest assured, there is very little added time for charging, and the 25w is less volatile than the 45w. This means, charging does not get the phone as hot, and the battery will have a better lifespan since slower charging is better long term. If you multi task a ton and/or save tons of files, consider spending the extra money to get the 512 gb edition, as it comes with an additional 4gb of ram (16gb total). Ram is what is used to have tabs open, so more ram means more tabs open while still maintaining speed and smoothness. The s21 ultra also has Spen support (need a case that can hold it). Why the ultra or base and not the plus? The s21 has a better ppi (pixel density, higher the density, better the picture) than the s21 plus. They both have the same 8gb of ram, the same storage sizes, same resolution, same cameras, same material, same flat screen, the same backwards wireless charging capability (same for ultra), etc. The only difference is the screen size and that the s21 plus has a 4800 mAh battery while the s21 has a 4000 mAh. The ultra however, offers higher resolution, much higher ppi, the larger screen, larger battery than both (5000mAh). The ultra has much more powerful camera as well, the curved screen, camera features and settings. So if you want all the features and performance and screen resolution (I like the stream movies on my lunch breaks) then go with the Ultra, if you just want to upgrade to the newest and fastest phone, and you don't need to have 100000 tabs open, get the base s21. ... show more
