[Samsung Galaxy S21 Ultra] Collin80:
Yes, i would suspect this. Unbeknownst to the average person, LED lights tend to flicker A LOT. They do this at a given harmonic of the line frequency. If you're in the US then the LED will flicker either at 60Hz or 120Hz. Most people can't see this at full speed as the light has a bit of persistence and we're geared to see smooth motion. But, when you slow it down you find that at 240Hz or 480Hz the video is now fast enough to catch the dark patches in between the pulses. So, the video seems to strobe. Not all LED bulbs will do this and those that do won't all do it the same. But, it's there, you just can't see it. Keep in mind when shooting video in other modes this could still happen. At 60Hz or 120Hz video even though it's full speed you are still potentially capturing some frames in between pulses. This could cause a sort of beat frequency to appear. So, if anyone is having that problem when trying to shoot video your options are 1: do it in the sunlight. The sun doesn't flicker. ;) or 2. Get a constant light source. Fluorescent bulbs have greater persistence as do the old incandescent bulbs. Professional lighting will be consistent too. But, $4 LED bulbs are going to SUUUUCK for slow mo video.
[Samsung Galaxy S21 Ultra] Keyvannn:
Yes. You were right. The problem was the led bulb.

That was interesting. 😁

Thanks guys

I follow the instructions to get YouTube Premium under my account - however only a 1 month trial offer is available. Does anyone know what I am doing wrong? I also went to youtube.com/premium/samsung and get the same result - 1 Month. Please advise.

Thanks,
[Samsung Galaxy S21 Questions] tfn:
I believe if you ever had the 3 months free offer before, it won't let you use it again on the same email/I'd.

It was like the free 1 year onedrive offer that you would get with Samsung devices.

If you used it once it wouldn't let you get another unless you use a different email.
[Samsung Galaxy S21 Questions] netnerd:
i currently have Youtube Music premium, it only shows 1 free month trial.

you right, i logged in Youtube with a different email, it shows 4 free month trial, i thinking of going this route. i love to save money, 4 months free is like 40$ for Youtube Music.
[Samsung Galaxy S21 Questions] aaronc_98:
ah ok. But I don't think that I ever signed up to any free trial in my case, so not sure what is happening here.

Thanks,
[Samsung Galaxy S21 Questions] SiNJiN76:
I know that when you first boot the app it offers 1 month...but I believe if you go into settings and select Get Youtube Premium it offers more. What's weird is that I thought it was 4 months as well. Maybe the 2 offers stack? I wont be redeeming the offer since I already have an account with premium.

I sewed the Indian version of the firmware using brom and the SP Flash Tool, lost imei without backups. I studied the topics in detail, I need engineering firmware for recovery, but neither of the two versions is installed. The error is as if the firmware is not for my region (0xC0050005).

thank you very much for catching this, it is absolutely a note 9 pro (joyeuse) .. havent looked up name recently until i had trouble with it.

Have had it for about a year, never a problem until Iast few weeks.

I d o get service when i am in an older zone that has 3g towers.

Hi!

Is there any solution without rooting for good quality call recording on S21 Ultra?

Okay, i know it google disabled this function since android 9/10. But on Mate20Pro there is an apk thats working on android 10 with good quality,recording microphone and incoming voice.

Every apps i tried works only on microphone side. Incoming voice is weak and bad quality, its only recorded through microphone if you set up the volume.

Any solution? Thanks!
[Samsung Galaxy S21 Ultra] peppegrecio:
I am also in your situation, I tried to flash with ODIN firmware THL but nothing to do, the phone always remains with csc OMN, unusable for me without call recorder, thanks for suggesting a solution.
[Samsung Galaxy S21 Ultra] westeight:
Call Recorder - Record Phone Calls From the Line (skvalex.com)

Have you tried that yet? Works perfectly on my S20 Ultra, but haven't (yet) set up my S21 Ultra, so haven't tried it.
[Samsung Galaxy S21 Ultra] peppegrecio:
it's the program I've been using for 4 years. I bought the full version, but without the native recorder you can't hear the voice on the other side
[Samsung Galaxy S21 Ultra] HUNRain:
Not working...
[Samsung Galaxy S21 Ultra] carlitobahsoun:
the only solution for me till now , is to flash XID home csc that will not wipe ur mobile .

i have exynoss s21 ultra , my csc was MID/MID/MID/XSG

now its XID/XID/XID/XSG

i got ota update.

and my csc was oxm multi csc .

xid not multi csc its OLE csc .

that why it work for me , THL not work coz its multi oxm csc same xsg or mid so will nit change till u use THL sim card.
[Samsung Galaxy S21 Ultra] peppegrecio:
the problem is that whatever firmware I try to flash with ODIN it seems that the phone does not see it and remains with previous firmware, I notice this because the progress bar never reaches the end and restarts first restarting with oxm firmware

your suggestions seem to work, I want to thank you infinitely

Thank you :)
[Samsung Galaxy S21 Ultra] y2kkingboy:
I'm here to report that thanks to @carlitobahsoun I was able to get native call recording working.

The steps are as follows.

1. Download the Indonesian firmware. You can download it from Sammobile here and I uploaded it to MEGA here

2. Download Odin tool. from same page on Sammobile or MEGA here

3. Unpack both files.

4. Run Odin and attach the files on the right side as shown in the attached image. Note, in the CSC field, If you want to keep your data and

not

format your phone use HOME_CSC. To format it use CSC_.

I used HOME_CSC.

5. Put the phone in DFU mode. While the phone is unplugged and adequately charged and completely off. Plug the USB to your PC, then hold both volume buttons and then plug the USB .

6. Click Start. It will take some time and should say Pass in green color and it will reboot automatically.

That's it.

I'm a total newb, so please excuse my ignorance. I'm on a Verizon s21U in the U.S. Do I need to root to do this? Adding this feature does not wipe anything on the phone?

Everything is running as expected so far. Can't see anything missing.

You can find which firmware you have now and download it beforehand. After flashing the Indonesian firmware, if you noticed something missing from how it was before, just flash back the original firmware in the same way I illustrated. You will be back to it as nothing changed.

Hello, just a question.

But only Indonesian firmware permit to use recording call function ?
[Samsung Galaxy S21 Ultra] carlitobahsoun:
nope , there are 7 or 8 country , but we cant change csc to this csc country coz its multi oxm csc , so if u flash nothing will happen till u use thiere sim card , thats why we use XID csc as its OLE csc not multi oxm csc and without Indonesia sim card.

hope i explains well.

post region or csc that have native call record by default , but all are multi oxm csc

Anyone know if any firmware that supports call recording will work with QUALCOMM variants?
[Samsung Galaxy S21 Ultra] carlitobahsoun:
nope , u will break ur mobile as no snapdragon firmware for Europe and asia , as snapdragon not MULTI OXM CSC .
[Samsung Galaxy S21 Ultra] carlitobahsoun:
egy : egypt csc .

to be clear : samsung csc detect by ur sim card .

for example : my csc was MID .

if i put egy sim card it will change to egy csc.

but IF I FLASH EGY FIRMWARE OVER MID without egy sim card it will not change coz :

1- detect csc from sim card

2- egy and mid are MULTI OXM CSC .

BUT

XID CSC IS OLE NOT MULTI OXM CSC .

so if flash using odin over MID it will change and once reboot the phone detect that ur csc not same that ur sim card and asking u to change OR keep current , simply select keep current and mobile will work normally .

hope i explains well.

sorry for my english too.

Sorry but I am not an expert on this topic. On the attached pictures there are the details of my uk firmware version, Vodafone UK. I would like to install the Indonesian firmware to get the call recording working using the home_csc option. I have few questions if you could help

1) is the Indonesian firmware the most appropriate and is going to work?

2) am I going to receive software updates (even if related to Indonesian schedule) ?

3) is SamsungPay still working with uk cards after the update?

Thanks a lot!

I understand that the firmware is made of multiple files. When you suggest to flash only home csc, do you mean to flash only this single file ? Or do you mean to flash with home csc option (and so to flash all the firmware files) ?

I guess that if something should not work I could just flash back the original UK firmware and everything should be back as it was.

Really appreciated

[Samsung Galaxy S21 Ultra] eyeatoma:
So this is really weird. I just did this with the UK software (BTU). It worked and flashed. It says I have the new firmware, but my CSC is still XID and not BTU. But weirdly enough things have changed. When I donwload the samsung pay app from google store, it doesn't immediately reject me. It loads and then says theres a problem, but I need to restart the app or check that i have the latest version of android. This is all in German btw, which is odd because I got the BTU version. I clearly still have Indonesian apps though (this is an Indonesian S21 Ultra). My galaxy store is still in rupiah. However here's another weird thing. The Indonesian version of Samsung Pay is gone. I'm so confused what has happened. I chose the HOME CSC so it wouldn't format my phone. SHould I have chosen the normal CSC to get it to change? You said I didn't need to, so I'm confused haha! Any ideas? Thanks!
