As far as i know , in india ecg and bp are not official at the moment .

I saw a youtube video , where he told to install 2 apps from a samsung mobile ( one of which was samsung health monitor)

And he was able to run ecg and bp .

Is that true ? Are those apps reliable ?
[Samsung Galaxy S21 Ultra] Sukrith:
Nope they aren't reliable! I bought the watch basically to monitor bp and whatever is the bp you measure during calibration, it'll show +/- 10 of that! If you simultaneously measure with the bp machine, you'll understand! So once I got the new phone, I didn't bother to install it again! Only thing is you can set up Samsung pay if u change the csc but it won't give you rewards but will give you convinience because of which I use it at times but the process is a mess!
[Samsung Galaxy S21 Ultra] aj7400:
See bp is something a smartwatch cannot measure .

It requires tightening of arm to measure the blood pressure .

I guess no smartwatch can give accurate readings as they all just use light based sensors which reflect the light and they try to give a close reading to what actually is .

Heart rate could be measured easily and a 2k band can do that as well.

Ecg should be preety accurate in a smartwatch because that uses actual procedure of sending electric waves from one arms and measuring it at the other arm .( heart it between)
[Samsung Galaxy S21 Ultra] enigmaamit:
Looks like my source was correct. Redemption for watch active is now open for customers who activated their phones upto 25th March.
[Samsung Galaxy S21 Ultra] abhi021:
So I got the device with the screen replaced on 12th March along with battery.

After using couple of days I noticed when using camera it asked to clean the lense. Inspite of doing that it still kept on asking.

On close check I found out the service centers had done a shaddy job while replacing the screen where all lenses had dust particles inside with finger print mark. Took back to the service centers and they called for the new camera modules to place the same along with the back glass.

This time around my device stayed with them for 4 days. On receiving it, it was no different than what it was earlier with pathetic service. See the attached pic.

Decided to mail Samsung CEO office and raise the issue with them.

After which was asked to send the unit to another service center which would again check and carry out the repairs.

I did submit the device at suggested service center However this time around I asked for replacement or refund of the invoice amount of the device that I paid.

Finally after 10 days my device being in service center they have agreed to refund the amount.

Overall it's a great devide but the service centers are pathetic. The 2nd service center I went to pointed out the back glass was not fitted properly as it should be and would have risked the device it any water or liquid would have spilled in.

Clearly it's not a device that can be repaired that easy.

Although I liked the S21 ultra as a device but am dreading to back with all the issues I faced with it.

Considering S21 any suggestions would appreciate it.
[Samsung Galaxy S21 Ultra] Sukrith:
There aren't many devices you can consider right now! You can go for Mi11 Ultra or wait for the next fold or flip but would be more expensive than the S21 Ultra! If not I would suggest go back to the S21U itself because it actually is a no compromise phone!
[Samsung Galaxy S21 Ultra] enigmaamit:
I feel very bad for you man. Would never wish for anyone to go through something like this.

At the same time I'm happy that you will get the refund! That's better than running from one service center to another trying to get your device in perfect shape.

If I were you, I'd consider this a second chance. Not many people get to return their device and get full refund. You can now choose to go for whichever device you want.

Honestly speaking, if it was me, I'd get a new S21 Ultra. In the two weeks that I've had this phone, I've fallen in love with it and wouldn't buy any other current generation phone.

Enjoy your second chance. Do let us know what device you go for, even if you leave this device forum.

Happy hunting!
[Samsung Galaxy S21 Ultra] abhi021:
I had my device for 40 days until the screen died on me. Someone else to from Bangalore here faced the similar issue. Clearly the LTPO display is more prone to have this display issue than other S21 models.

I had my device purchased in prebooking delivered on 30th Jan until 10th March when it died.

Am not too sure how many people are facing similar issues. But until one is not stern samsung will take you for a ride.

I can have new S21U for 85k under corporate. Have the watch, tag, led case since it was pre-book device and I purchased the leather case too. Just have to get device. But not sure if this display issue may creep in anytime again within a year of usage.

Fold 2 is available for 132k with the freebies. But this time more inclined towards small formfactor of S21.

Mi11 ultra is around the corner but don't think would like miui skin or that bulk of the camera plus I doubt Xiaomi will have optimise software.

iPhone 12 is something I would consider but spoilt using that 120hz refresh rate after using 90hz on OnePlus 7 pro.

So not many polished choices.
[Samsung Galaxy S21 Ultra] enigmaamit:
Tried looking into it, found multiple reports of the same.

https://r2.community.samsung.com/t5/Galaxy-S/S21-ULTRA-WENT-BLACK-SCREEN-SUDDENLY/td-p/7306192

Maybe this is seriously a problem... Hope it's just a bad initial batch and not a problem in the screen design itself.

Any details of the manufacturing date of your phone? It might help narrowing down the problem if its batch related...
[Samsung Galaxy S21 Ultra] abhi021:
Remember manufacturing date around 28th December.

Guess this is more common issue like I said with LTPO display. Living with the fact that screen issue may creep up anytime is crazy
[Samsung Galaxy S21 Ultra] enigmaamit:
That would mean OnePlus 9 Pro users will also face similiar issues? (If LTPO tech is to blame?)

Will be watching this with interest. I just hope it was a bad batch and the issue has been fixed in later devices. Otherwise Samaung has a big s***storm heading their way.
[Samsung Galaxy S21 Ultra] aj7400:
Mi 11 ultra is a good option .

But miui and mi optimizations and poor software updates and support kept me far away from mi .

I can never go back to 60hz screen now.

My wife's 12 pro looks slow , sluggish and pathetic while scrolling .

I get easily irritated using a 60 hz screen

Either buy the oneplus9 pro or stay with s21 ultra ..

There are million others with s21 ultra , i dont think there will be an issue with display , else samsung would recall all phones just like the note 7 battery issues
[Samsung Galaxy S21 Ultra] Virgo_Guy:
Faulty displays or such cannot force Samsung(or any other maker) to recall a product as per history, but exploding batteries certainly can as they are bound to, to avoid ban to say the least.
[Samsung Galaxy S21 Ultra] aj7400:
But at first place ,i dont expect samsung to make faulty displays .

It could be an initial batch ,

But those screens are being used in samsung , apple , xiaomi , oneplus and many more devices.

If such faults arise in this technology, then every brand using these displays are bound to expect a tsunami of complaints.
[Samsung Galaxy S21 Ultra] Virgo_Guy:
Cheque or coupon refund? Based on past experience, coupon only works in Samsung exclusive stores even though Samsung management said it would work in other authorised outlets for Samsung products that didn't.

The batterylife is a concern with the vanilla S21. The plus model doesn't have that issue, while still being light and handy in comparison to the Ultra.
[Samsung Galaxy S21 Ultra] abhi021:
Was given the choice of coupon, but asked Demand Draft.

S21 does have smaller battery but like the fact it's good form factor for one hand use
[Samsung Galaxy S21 Ultra] enigmaamit:
Do you remember it's country of Manufacture? Might have something to do with the assembly line ? I'm just guessing here but if we collect all possible variables, we may be able to see a pattern if this happens to more devices as time goes by
[Samsung Galaxy S21 Ultra] abhi021:
Vietnam
[Samsung Galaxy S21 Ultra] enigmaamit:
Thank you.

To the best of my knowledge, the S21 lineup is being manufactured in one of 4 countries as of now: Brazil, Indonesia, Korea and Vietnam. The India factory (Samsung's largest) isn't making the S21 phones right now.

Need to ask around if the black screen units share anything in common. The three variables I can think of currently is the processor, the manufacturing date and manufacturing country.

Incidentally, my unit is also made in Vietnam, Feb 2021, Exynos.
[Samsung Galaxy S21 Ultra] abhi021:
Manufacturing country are allotted certain countries they manufacture for. India could be one of them. I doubt if any country are supplying s21 series in India
[Samsung Galaxy S21 Ultra] Sukrith:
In case none of you know... The s view case with S pen costs 7k!😑😖
[Samsung Galaxy S21 Ultra] lendawg:
I got the oneplus 9 pro from tmobile but I'm considering exchanging it for the s21 ultra. Tell me why I should.
[Samsung Galaxy S21 Ultra] enigmaamit:
Why are you considering shifting from the OnePlus? You must have your reasons already if you are having second thoughts about your device.
[Samsung Galaxy S21 Ultra] aj7400:
Watch offer live for customers who activated uptil 31st march ..

Redeem it go go go
[Samsung Galaxy S21 Ultra] lendawg:
Not having any issues with the phone I actually like it a lot and the screen is great, it's fast af etc. Just wondering if the s21 is much better battery, smoother, much better camera etc. I hear great things about both phones so just want to know people's experience with the s21.
[Samsung Galaxy S21 Ultra] Sukrith:
This wouldn't be a good place to get an unbiased opinion!😅

Having said that I'll give my prejudiced opinion... I've never owned OnePlus but nowadays it's becoming more oppo and Vivo than what I used to feel about OnePlus (this is based on years of following tech)! That's why I didn't get or even wait for a OnePlus... Having used the S21U for almost 3 months, I actually feel it's a non compromise phone! Software updates keep coming, non buggy, I don't play games but overall really good performance and the camera is actually good! I went for a trip recently and the phone helped me get some great photos of wildlife... But since I haven't owned or used a OnePlus, I feel the S21U is superior to that... Some reviews even favor the S21U on the camera front! This is my 2 cents... If you actually wanna have a phone that you wanna keep for atleast 2 years+ without much of a headache (in terms of service and software updates) get the S21U if not the OP is also good!
[Samsung Galaxy S21 Ultra] enigmaamit:
Most of the questions you've asked, I'd recommend the S21U over the OnePlus 9 Pro. I am a long term OnePlus user and had OnePlus phones from the out original OnePlus 1 to the OnePlus 6 (my last phone)

This year, I decided to skip the OnePlus in favour of Samsung. I made that decision after trying out both phones at my local electronic store (display pieces). The S21 Ultra just feels better in the hand. OnePlus feels like a cheap toy in comparison with a generic design that looks like a every other phone in the market.

Battery life is undoubtedly better on the S21U. Heating issues are worse on the OP9Pro.

The only things OnePlus has going for it is the fast charging, the gaming performance (on SD 888 vs Exynos 2100) and the price.

If you've already used the S21 Ultra, you will regret shifting to the OP9Pro unless the above 3 things are very important to you.
[Samsung Galaxy S21 Ultra] lendawg:
Very good answer and I appreciate it coming from a previous oneplus owner. What is your average screen on time / usage like on the ultra? On 50% wifi 50% data I'm averaging 7 to 8 hours screen time for the oneplus 9 pro and having no heating issues. Does the s21 ultra do better then that?
[Samsung Galaxy S21 Ultra] Sukrith:
I'm getting 7hrs+ sot with 16hr usage and 23% remaining
[Samsung Galaxy S21 Ultra] lendawg:
Awesome thanks!
[Samsung Galaxy S21 Ultra] enigmaamit:
Not sure. I've never killed the battery in a day so far and I charge my battery partially every day to around 80 to 90 percentage before it drops below 30.

Maybe someone else here can answer that question better.
[Samsung Galaxy S21 Ultra] Sukrith:
I know this is out of context but I'm planning on getting a new head unit for my car and I'm torn between android auto one or full android unit... Which would be better based on experience?
[Samsung Galaxy S21 Ultra] aj7400:
I think the full android one is going to be laggy due to poor hardware . I have never experienced a 3rd party android based system that is not laggy and slow.

But it will have loads of extra features.

Android auto will use the power of your phone to display all content and process it.

It has basic functionality like calls ,music , maps but i guess that is all what you will need while driving .

Another point is updates , the full android one is never going to be updated , and the android auto one , since it works through phone, it will get updated and may bring new features as well .
[Samsung Galaxy S21 Ultra] Kiran-Kumar:
People who bought in Jan received 10k cashback?
[Samsung Galaxy S21 Ultra] Rattlesnake3:16:
How many of y'all are having Auto Brightness issues with the phone? Mine doesn't work properly 70% of the time or takes a long time to adjust according to the ambient lighting.
[Samsung Galaxy S21 Ultra] enigmaamit:
No issues here. Working fine.
[Samsung Galaxy S21 Ultra] karan2012:
Not yet maybe next month
[Samsung Galaxy S21 Ultra] dhanabalan19:
Not yet. Waiting for it.
[Samsung Galaxy S21 Ultra] Sithlordpt:
Yup. Sometimes it works, sometimes not. It's inconsistent.
[Samsung Galaxy S21 Ultra] Rattlesnake3:16:
Just hope they address this in an update. I've had phones costing a fraction of the S21 Ultra with much better auto brightness adjustments. This one behaves a bit too erratic.
[Samsung Galaxy S21 Ultra] aj7400:
I had problems before the factory reset .

Now it seems to be fine after the factory reset .

I still think its inconsistent may be because its under display.

I do have problems with the proximity sensing though .

( proximity sensor and light sensor are same this time , i think )

Anyone who bought the phone in april? The watch redemption was to go live today
[Samsung Galaxy S21 Ultra] enigmaamit:
Right now it's only open to those who activated their phones in or before 31st March.

But I've noticed that the update in Samsung Shop usually occurs on the late afternoon or evening. The eligibility update from March 17 to March 25 deadlines happened at 6:30pm, and later the update for 31st March deadline happened at 3 pm.

So maybe check later in the day if your information says that the offer for May activation is supposed to go live today.
[Samsung Galaxy S21 Ultra] Veestaai:
Thanks for the info! Do the stock finish instantly or they have plenty?
[Samsung Galaxy S21 Ultra] enigmaamit:
They didn't have silver colour when I ordered. Black and pink were available.

Didn't wait long enough to find out if it goes out of stock. Ordered within 15 mins of offer opening up. 😂
[Samsung Galaxy S21 Ultra] Bidyadhar:
In Love with this piece of tech.. Thank you Samsung for the watch offer!!
[Samsung Galaxy S21 Ultra] Veestaai:
Did anyone redeem active 2 watch, who bought the phone in april?
[Samsung Galaxy S21 Ultra] enigmaamit:
Right now, redemption is only open to people who bought and activated their phone on or before 31st March 2021. If you bought it in April, you can't redeem the watch right now. Will have to wait till they extend the dates.
[Samsung Galaxy S21 Ultra] deepakpc007:
Contacted Samsung customer care regarding this today, they said that the redemption date has been postponed by 3 days. They told me to check after 10 am on 28th April.
[Samsung Galaxy S21 Ultra] aj7400:
A new update is seeding in germany ,

Expect it in a few days in india.
[Samsung Galaxy S21 Ultra] sasha8200:
Any update on HDFC Cash Back.

I purchased on 25-Jan with first billed on 3-Feb. But have not received cash Back till date. Its more than 90 days
[Samsung Galaxy S21 Ultra] enigmaamit:
Have you called up HDFC customer care? They are the only ones who will have any real clarity.

If you've used the exchange bonus, then the bank cashback may not be applicable. Or at least that's what the reliance digital salesperson told me when I bought my device. He said you can get either one of the offers. I still paid using my HDFC credit card, hoping he was wrong, but haven't heard anything about the bank cashback yet...
[Samsung Galaxy S21 Ultra] Kiran-Kumar:
Yesterday was the 90th day....feb had only 28 days and a couple of days for emi processing.

I called them yesterday and they said it will be processed today and will reflect in 7 business days.
[Samsung Galaxy S21 Ultra] Veestaai:
Any update on this?
[Samsung Galaxy S21 Ultra] enigmaamit:
That's very good to hear. Did you opt for the exchange bonus too?
[Samsung Galaxy S21 Ultra] deepakpc007:
The redemption is available for devices activated till 10th April 2021. I was able to redeem successfully.
[Samsung Galaxy S21 Ultra] Veestaai:
Black color is available?

Also, how was the rollout for march activations?
[Samsung Galaxy S21 Ultra] deepakpc007:
Black was available when I ordered. I think the other two colors were available as well. It is showing May 6th delivery date. Not sure how that will pan out because of covid.
[Samsung Galaxy S21 Ultra] Veestaai:
Great! Enjoy the tech brother

Thanks bro👍
[Samsung Galaxy S21 Ultra] enigmaamit:
I wish I could answer that but I rarely run out of battery so I honestly don't know. I top up when I can and my battery hovers between 30 and 80 percent. It's healthier for the battery. So I don't have a full discharge cycle yet...

However if I was to extrapolate based on my usage I'd say SOT would be around 6 to 7 hours with moderate usage including camera, 30 mins CODM and usual apps.

Wish I could be of more help...
[Samsung Galaxy S21 Ultra] Kiran-Kumar:
I bought it on launch day....it was either 10k cashback or 10k exchange bonus.
[Samsung Galaxy S21 Ultra] Kiran-Kumar:
Got my HDFC 10k cashback credited yesterday. Raised a req for emi closure.

Done with S21U.

Sold it long back when the power button broke. :p

Got z fold 2 and I'm mighty pleased with every aspect of the phone, except camera.
[Samsung Galaxy S21 Ultra] aj7400:
Still no may update for india ?

Why dont samsung release an update worldwide just like Apple?
[Samsung Galaxy S21 Ultra] Veestaai:
You can download the latest update using frija and flash using Odin.

Was just seeing unboxing of the phantom silver s21 ultra... Seems that there's no need for buying a camera protector or skins for the side and back because unlike the black one, everything is transparent on the silver phone!😍
[Samsung Galaxy S21 Ultra] nick191:
I am waiting since N20U launch as there was EXYNOS 990 I had to skip it otherwise that Bronze colour is just something different. I don't regret waiting as Silver one is just 🥰😍. Although I have experimented with two other phones just to keep my self occupied. 😂
[Samsung Galaxy S21 Ultra] Virgo_Guy:
I wouldn't that much depend upon phone storage and be unafraid of losing some data somehow without backing up somehwere in the first place and then free up enough space to be at peace.

Several stores will be able to start selling 512 GB variant from 25th anyways as far as I'm aware.
[Samsung Galaxy S21 Ultra] krkdesigns:
Anyone here pre-ordered the S21 Ultra using the VIP Pass?

It says in the email "You will also receive a free Smart Clear Cover with your next Galaxy smartphone"

Also, I checked with the Samsung chat support team and they informed us that once we place an order and once the phone is delivered, we will have to log in with the new phone to the Samsung app and we can redeem Samsung Active 2 for 999rs, Free Smart Tag and then because of the VIP Pass a free Smart Clear Cover.

Can anyone confirm the same?
[Samsung Galaxy S21 Ultra] kannanX10:
It seems N20U will be last one in the note series.....Iceuniverse has tweeted about it
[Samsung Galaxy S21 Ultra] zaydenQ:
I ordered using the VIP pass. The Samsung chat support guy said the cover will come with the phone (he couldn't say if it would be the same package). Same with the smart tag. But for the watch active 2, it would be redeemable 3 days after activating the phone with the same number. It will show up on "For you" tab on Samsung shop app.
[Samsung Galaxy S21 Ultra] nick191:
Yes, I have also been told the same regarding the Watch part. Although I haven't ordered using VIP PASS !

Samsung Galaxy S21 Ultra review: A capable but costly flagship

In many ways, the Galaxy S21 Ultra is a by-the-book upgrade — it’s faster, its cameras are more polished, and its software is a little cleaner. Calling it a thrill would be a stretch. With that in mind, the Ultra absolutely shines this year, not because of game-changing updates, but because it...

www.engadget.com
[Samsung Galaxy S21 Ultra] Virgo_Guy:
This was very much expected. And since developers historically have been optimizing games for the Adreno only and Mali rarely gets that love, the gap will not shrink, would increase.

This Mali GPU would be the weakest of all flagship GPUs in 2021. Saying this because this 14 core Mali GPU is weaker than the Adreno 660 in the Spadragon, that itself is weaker than the 24 core Mali G78 in the Kirin 9000 chipset and even last year's Apple GPU in the A14 Bionic! Probably one shouldn't go for this Exynos ver. if the person is a heavy gamer.

I am way more interested in batterylife and performance throttle results.. 🧐
[Samsung Galaxy S21 Ultra] Sukrith:
Every tech reviewer is complaining about the video quality of the S21 series... But seems battery life, display and performance is good!
[Samsung Galaxy S21 Ultra] Sukrith:
I usually don't play any games on my phone's unless I am that bored... Then I'll download something and play and uninstall! But I really just wanted to know my phone will handle everything I throw at it!
[Samsung Galaxy S21 Ultra] Kiran-Kumar:
