[Samsung Galaxy S21 Ultra] Max128:
@mc_365 So you have the phone with what I have understand? Well I know is since the s7 I think the us and Canada having a locked bootloader and I find it stupid from Samsung really. For the NFC payment , my last three phone having it I think and I am still not using it.. Still not really interested by this. Well the root for me is still pretty important , I am using it for some reasons...

Well my last two HTC devices I have buy the global version and everything work.. and the phone work great too, and warranty on this. Is for Samsung phones I am a bit lost.. for the global version ( because the bootloader is can be unlock and also global version phone is always less expensive I buy my phones full price) what is working in Canada and what not...
[Samsung Galaxy S21 Ultra] mc_365:
Yes I own the Phone.

I bought the phone outright as I do most of the time.

The non US/CAD phones are unlockable because from my understanding the law requires it in Europe. In the US the I think the carriers are concerned with subsidized phones being hacked for use without paying the phone off. That in combination with the US credit card companies concerns about fraudulent payments from hacked devices. These 2 major industries (Telecom and Banking) force the manufactures to adhere to these demands. So US/CAD and EU being the 2 major regions with strong governing laws force companies to comply or not be allowed to sell direct to consumers. Samsung has decided to just make it easy and keep everything coming to the US and CAD locked down tight. Europe must have their phones unlockable and the Chinese probably have some rules, and that's why they have Snapdragon chips and the rest of Asia has Exynos. There's probably some back door built into the Chinese variant for the CCP to monitor or to enforce the firewall etc.

Global version is less expensive because it has Samsung's Exynos processor which was somewhat inferior to Qualcoms Snapdragon in the past. Also in my experience you only save on the Global models after the phone has been on the market for a while. When it is relatively new you pay a premium to get that device from an importer. And again you get no warranty or support.
[Samsung Galaxy S21 Ultra] Max128:
How do you like the phone?

Not exactly , the global version I am talking about is the SM-G9980 and is the Snapdragon model ( Hong Kong ) is unlockable. I have buy my last two phones at launch day and is 200-300$ less like the s21 ultra right now... And I have got a support and normally a warranty.

However, not very precise for the bands network here. I am looking for that is will be the same for all Samsung phone I guess.
[Samsung Galaxy S21 Ultra] mc_365:
Well as far as I have ever know, Samsung does not offer any warranty or servicing on devices purchased outside the region it was intended to operate.

Maybe the specific vendor your buying through is willing to warranty the device. But according to everything I've read and every place I considered buying from its always been stated up front,"Intl version NO Warranty" and the Exynos versions were cheaper but the Chinese version were just as expensive and more in a lot of cases. I've also heard of people receiving the phone and the language be set to Chinese and they could not operate the phone, LOL.

If my S10+ had 5G or 120hz screen I would have stuck with it. S21 Ultra is a great phone but in reality overkill for me. But I got $700 worth of trade in credit 500 for the phone and 200 worth of new accessories. So for ~$750 tax included and my old phone, I got s21 Ultra 512GB, Buds Pro, Soft touch Silicon + Spen case, Soft touch Silicon case, Clear TPU case, Rugged Hard Shell case with Kickstand, and a tracker tag thingy.
[Samsung Galaxy S21 Ultra] netnerd:
the s21 ultra is FAST and smooth.

i going to keep it for a few years unless the newer phones are a lot better.
[Samsung Galaxy S21 Ultra] joancolmenares:
I have the 988B/DS and I love it. I had a note 20 Ultra and I traded it for the s21 Ultra and I don't regret it.

Durability: Phone has Gorilla Glass Victus (latest one) on the screen and on the back as well, really premium look (love the phantom black color). I don't plan on dropping the phone to test it lol, but videos show quite a lot of durability in drops up to 10feet. I will get a case to protect it just in case.

Storage: I don't miss the SD card (havent used one in over 7 years). I have the 256GB model one (12GB ram) and with cloud storage I don't think i will ever get close to filling the phone.

Cameras: I love the cameras, but it does get a bit to get used to the different options and mastering it for pro photos. It really is something else.

Processor: i have the Exynos version and I can't find any lag or issues with it. no overheating (this seems to have been fixed with an update), no issues at all with the phone.

Battery Life: With the 25W charger, from 0 to 100 in about 100 minutes give or take. It does charge fast, keep in mind that the battery is 5,000 mah so I don't think it's bad charging time.

Honestly? It is worth it... Not sure if changing from HTC will mean a lot of getting used to, but it's a nice experience.

I don't think flashing firmware to other models will result in 5G band compatibility, you can enable other market dependent services, but I believe network bands are more of a hardware thing.

About rooting, I used to root all my samsung phones and play around (and brick some phones) along the way, but I don't know why, but tripping knox and messing up banking capabilities is not of my interest. I'm happy with the phone as is and don't intend on rooting (disappointing I know).

Hope these comments help a bit on your decision making process
[Samsung Galaxy S21 Ultra] Max128:
Thanks for your answers! When I have buy my HTC phone global version I had always every languages even the French ( the French is my principal language ) but with what you are saying the global of Samsung do not have this, China language? Can you flash firmware of another country on it like Canada? I do not much how Odin works... Yeah I am still not sure about the network bands compatibility and if is a software things or hardware? I saw posts that said it was one or the others things... Not really specific!

Disappointing? Yeah? Haha! Well in your place i wouldn't stop myself if the device you can unlock it !l Also in the reviews I have see is take approximately 1h11so 70 minutes to charge completely the phone with a 25w charger , why a big time difference here?
[Samsung Galaxy S21 Ultra] joancolmenares:
I used to root all my samsung devices (I stopped in Note 8). About the battery charge time.. I haven't let it go to zero lowest I have gone is like 35% and then charge so my calculation was based on the time to charge from that point, so 70 minutes is NOT bad at all...

My version has French language as an option in intitial setup (it has a bunch of languages - pretty sure it covers all needs).

Also, reading further in the forum, 5G bands are more software related (enabled), so it seems flashing firmware will enable/disable bands.

There are many posts in the forum on how to flash different firmware or change CSC codes so youmight want to take a look there. Odin is pretty safe to use if you follow the instructions. I haven't used with recent samsung devices, so I'm not sure what considerations you need to take.

I love the phone, but then again, I do not get to deeply play with it (unlocking the bootloader, rooting, flashing) as I did with other devices but I'm ok with it (for now). Given it's a pretty new device, it's kinda hard to find stuff for it yet.
[Samsung Galaxy S21 Ultra] mc_365:
I think the time difference is because we are not testing the battery with stop watches we are just telling you what it says on the screen when we plug it in and giving you an ball park estimate. It always says a longer time to full charge but ends up being faster as the battery calibrates during the charge process. Its like when you down

load a large file from the net it first starts off saying 20 minutes but then only takes 5.
[Samsung Galaxy S21 Ultra] oae08:
If they don't fix the camera, especially taking photos at night (Exynos2100 version), Do NOT buy this phone
[Samsung Galaxy S21 Ultra] Max128:
@mc_365 I understand now what you are saying... Thanks!

@oae08 What is the problem exactly with the camera? I do not see that on the reviews , good to know if you have a problem! Do you know if is Snapdragon too ? Or only exynos
[Samsung Galaxy S21 Ultra] Max128:
So your 988B/DS is the global version ( china and global is the same thing as a know ) on Exynos if I understand? And you have French on it and many others languages!

Do you have some links near for what you are talking? About the 5 bands and the software flash? No need for how to flash a firmware of CSC codes I know is easy to find this, but it is quite possible to do it, to flash the firmware of the country you want right? No problem on the device after this? Also you only need the bootloader unlocked for flashing a firmware on a another country I Guess ?

Well I know magisk is not working yet on the s21 but is will be soon.
[Samsung Galaxy S21 Ultra] oae08:
The camera is really disappointing. I have bought this phone for just over almost 1600$, which is above my budget actually) but I was really anticipating to buy a phone that has a monster camera that I can use to get decent photos point to click. However, this is not the case. The night time photos especially, are bad quality and there is too much flare. I have tried it in many different scenarios and cleaning the lenses in every possible way but still the flare is way over the acceptable. I even compared with iphone 11 photos taking the same photos back to back and the older iphone 11 results in much cleaner and better photos.

Please note that i HATE the iphone, but this is the truth unfortunately. So until samsung releases an update to fix this (if its even possible), the phone is not up to standard.

EDIT: I have the exynos version
[Samsung Galaxy S21 Ultra] joancolmenares:
Odd, I have the Exynos version and haven't had any issues with the camera in the many modes even night mode and it's awesome. I don 't know if the latest software update had something to do with it, but when I bought the phone and turned it on it updated and the update said camera fixes, so that might have been the case.
[Samsung Galaxy S21 Ultra] oae08:
Try the exynos version in a night photo but not night mode. It will be bad!!!
[Samsung Galaxy S21 Ultra] Max128:
@joancolmenares Do you have some answers for me in my last message? Thanks!
[Samsung Galaxy S21 Ultra] bartjeh1991:
Yes it worth it.

Battery ✅

Screen ✅

Build quality ✅

Performance ✅

Camera ✅

This is the best phone for android. You want the best, you have to buy premium.
[Samsung Galaxy S21 Ultra] mc_365:
So I did some further test and in fact it charges much faster if you have a "Superfast" charger.

Since the phone does not come with a charging brick, I was using whatever but began to feel like it was too slow.

So I got out every charger I had quick charge 3.0 , I bought a cheap (fake) quick charge 4.0 charger and went 1 by one charging from 0% Then I got to my LG v60 charger which is my back up phone so its fairly new. When I plugged it in the phone said "Superfast" charging where it had always said "Fast" charging. When using the a "Superfast" compatible charger the phone will go from 0% to 50% in 20 minutes and full charge in around 60 minutes.
[Samsung Galaxy S21 Ultra] whitehawk66:
Coming from an exceptional, flawless Note 8 experience for $648 to a Snapdragon S21 Ultra, i am very impressed.... awesome cameras, screen, battery life, design..etc.

And with a super pre-order promotion, I got this for $648 as well. They sure know how to market to me.

I like the bleeding edge toys, but I don't imagine I will ever be willing to pay $1250 for a phone.
[Samsung Galaxy S21 Ultra] Quazza:
Yeah, I really love this phone so far
[Samsung Galaxy S21 Ultra] Gzoom82:
I upgraded from the S9, Samsung gave me a good trade in for it against the S21 U, and than some additional discount on top.

It is very expensive but for me worth every penny. I love taking photos and I've never owned any other camera system that gives me so much creative possibilities in my pocket.

I genuinely cannot understand complaints about the camera, I have the Exynos version and the photos speak for themselves.

What's more crazy is the S21 U also has the best display I've seen on any phone, am getting 7hr+ screen time, and I can play games in max graphics modes inaddional to work emails etc.

I haven't even touched on work flow possibilities of DEX!!

For me the S21 U is worth every penny over the cost of my S9. I will be keeping if for a few years and will have no issues upgrading to the S24/25U in 2025 :)
[Samsung Galaxy S21 Ultra] arsenal74:
The FPS feels like a big upgrade. The actual difference is probably not much but it is noticeable in every day use. I always found the note and s20 ultra sluggish.
[Samsung Galaxy S21 Ultra] joancolmenares:
Exactly my point! I love how this camera setup works,,, I have taken great photos in daylight, night, indoors, outdoors...
[Samsung Galaxy S21 Ultra] Berserker900:
which variant you own?
[Samsung Galaxy S21 Ultra] Max128:
Hello guys! Your pictures look so great! Good work! Do anyone have got problem like overheating? Especially with the camera.. I have see some people here to complaint about this. Also what variant do you have? Exynos or snapdragon?
[Samsung Galaxy S21 Ultra] joancolmenares:
I have Exynos and have not experienced overheating when using the camera. I have recorded a 4K 2 min video, and taken pictures for over 10 minutes and I cant notice overheating.
[Samsung Galaxy S21 Ultra] mc_365:
I have the snapdragon model for the ulUS market.
[Samsung Galaxy S21 Ultra] cro-co:
Went from oneplus 7 pro to the ultra. Came from htc too before they died. Moved to essential phone which was terrible, then to oneplus. Really like oneplus, if I were you I'd wait for the oneplus 9 release and see what they have to offer.

Have a huge itch to fix some ui elements on the ultra but without root it's kinda hard (have US snapdragon variant, and updated before I realized I needed to stay on previous version if I wanted the boot loader unlock to work). With oneplus you can unlock the bootloader easy and install twrp plus magisk no problem.

Nothing particularly wrong with this phone though, it's just that one ui feels like it needs more professional polish. Also charge speed on the 9 is gonna be amazing with the 30/45 watt wireless charger and the 65 watt wired.
[Samsung Galaxy S21 Ultra] s3axel:
Coming from a Mi10 Ultra (and an Oneplus 8 Pro before that) I must really say Samsung has come quite a way and so far I indeed like my S21 Ultra.

The UI feels very fluid and smooth, the display is really great and the cameras are also very nice. Battery life is also pretty good, e.g. fully comparable to my rooted and tuned 8 Pro - but unrooted and full stock on the S21U !

I myself am pretty happy with the ultrasonic FP reader, though others claim issues - maybe something to do with the skin and so I am just lucky :)

Of course there is always room for improvement and maybe some will still happen over firmware updates.

All in all it is a true and solid flagship phone with (for me) most boxes ticked. "Most" because what buggers me is charging speed. I use wireless charging most of the time and have been spoiled by the faster charging speeds (25W and even 55W with the Xiaomi), the "fast" wireless charging in combination with the large battery means I have to get accustomed to charge it over night - no longer a quick wireless "top up"....

Oh, and it is indeed a heavy and large phone, just marginally on the comfortable side of it for me.

Is it worth it ?

Well, thats a good question with the prices for phones having risen as they did recently. I got mine over a carrier subscription, thus spreading the cost over 24 months - still a heavy investment, though. Having said that in comparison to the other flagship candidates it is in line pricewise....

WIth the prices rising as they are and the differences between phones becoming rather evolutional than revolutional it may become an increasingly valid tactic to buy last years flagship.
[Samsung Galaxy S21 Ultra] eldrid:
It depends on what you are looking for. The s21u is a great phone, probably the best money can buy right now. But its very expensive if you plan to buy it new. I had bought one when it launched but returned it as I was unhappy with the cameras. I found it to be versatile but lacking in quality i.e in lower lighting conditions the images were noisier than other phones ive used. But looks like they've fixed some of the software issues now but its still not perfect. I bought a note20u now for half price and can see that the software is a lot more refined and the prices are lower plus you get more in the box. If money is not a problem and you want to have the latest get the s21u. Else I think you're getting much better value with the note20u now. Also im getting really good battery life on the note20u and this is the exynos variant.
[Samsung Galaxy S21 Ultra] kipue:
Haha, Dex totally saved my *ss that day I forgot the charging cable of my Surface... Could do my presentation work nearly as well!

Really a good feature.
[Samsung Galaxy S21 Ultra] amirage:
Ok..so here's my 2 cents:

Camera - Absolutely the best that's out there across any platform by far. And this is only going to get better with more software updates over the coming months

Software - quite cartoonish but the level of customizations that it has is mind-boggling. I have had the phone for over 2 months and I have yet to figure out all the software components. My previous phone was the OnePlus 7pro and it's UI was just a level more than pixel. I knew the ins and outs of Oxygen OS in just 1 week.

The updates to the S21U have also been quite regular but I guess this would be so until the Note is released. But, I'm sure Samsung would be in much better shape than Oneplus 7 that's still in Android 11 beta when Samsung S10 is already on Android 11 (a device that's 1 year older than the Oneplus 7)

Screen: beautiful. Again, just like the camera, there isn't a device in the market that can match the S21U's screen

Heating issues - This is bound to happen if you have an app that is resource-hungry like camera/ gaming. This is not just limited to the S21 but can be seen in any device - mid-range, low-range, iOS. Both these apps use the CPU, GPU and RAM at

Overall, I like the S21U...Is it worth the asking price? No! But, it will be worth it in 3-4 months or closer to the launch date of the Note 21. Of course, by then, there will be a whole new slew of devices...
[Samsung Galaxy S21 Ultra] varcor:
Whether or not it's "worth it" is highly subjective based on one's usage preferences. If you're trading up from a 4 or 5 year old device it's likely to offer a number of improvements, useful features which make a difference. If you're trading up from an S20 Ultra or even the S10 Plus there's really not much of a difference. Coming from an S20 Ultra doesn't seem to make much sense, you're losing features like MicroSD and Internal Storage Capacity is reduced, no earphones and more. From a cost valuation it's hard to stipulate the device is "worth it" If Samsung didn't offer high dollar amounts on a trade-in the S21 Ultra would have disappointing worldwide sales volume. When you can receive close to the original cost of a trade-in that's hard to beat. I'd be very surprised if S21 Ultra total sales volume comes anywhere close to the S20 Ultra and it has zero chance of out selling the S10 Plus. Sales volume will have the final say on whether or not the S21 Ultra is "worth it".
[Samsung Galaxy S21 Ultra] Max128:
Great to see some news reviews here! I have read many of you in this page who made the switch to Samsung from oneplus. I can ask you all of you the major reason of this change? Is the software update? have see some people that said OnePlus is getting slow, and bugs for the software update.... I have already considered the OnePlus 9 but I do not want another brand with a poor support in update so I am not sure. OnePlus look the have a solid hardware though and the 9 pro look pretty good. Personally always buy the phone outright for some reason... I can choose the plan I want without limitation... I normally buy the global version of the phone, is dual sim, is always cheaper too and for Samsung the bootloader is perfectly unlockable for free with a snapdragon variant.... Only the 5g now is not the same bands but I don't really care also is bad on the battery life and 4g is fast enough... I am still looking for now
[Samsung Galaxy S21 Ultra] sanghaviraj:
Coming from note 10 plus, I think it's not a worthy upgrade at all, as the note Camera was literally same other then just night mode, which I guess will never use, plus I'm loosing s pen, and SD card, plus the phone feels bulkier to my note 10, the only thing improved is battery life and refresh rate
[Samsung Galaxy S21 Ultra] Kawaisa:
Coming from the Note 10+, The refresh rate is a noticeable upgrade for me.
