New Oreo Update Change Log/Release Notes?

Hi guys, a new Oreo firmware was released for the N950F under build N950FXXU3CRC7.
Is there a way to find a change log for this. Unsure if worth updating from CRC1 which is a custom rom. Whereas the new firmware build on stock could be better.
Thanks

Me too. Very curious.
There's a feature on Oreo that when you dismiss a notification it clears the app badge on launcher (even if you didn't read it), i've read somewhere that the last S9 update reverted this situation.
Does anyone know if crc7 reverted this ituation as well for note 8 as it's keeping me on Nougat although i really wanted to do the update.
Thanks

I'm not seeing new/second Oreo release for XEF or multi/OXM. What country & is it a first or second release? Sounds like it just may be a carrier specific 1st time Oreo release.

He is from Australia.

I see, yeah as I suspected, I wouldn't consider that an upgrade from CRC1.

You can easily update the phone yourself using odin to flash the newest firmware version! You don't have to wait for your carrier to do it just go download the newest firmware for N950F and flash it and just do that every time a new one comes out.

If you're only updating you should be fine however I would still suggest you use Smart Switch from the play store and make a backup of everything on your phone so it saves the backup to your SD card so if anything goes wrong you still have everything and you just use Smart Switch to restore it all.. You never do anything to your phone without making a backup!

Note 9 stuck on Android 8.1.0

I just got the Galaxy Note 9 (SM-N960F/DS) and it's still on Android 8.1.0, security patch level December 1, 2018.
It won't update OTA, nor via Smart Switch.
The build number is M1AJQ.N960FXXS2ARL4, CSC is N960FOXM2ARK2
Is there a way to update it to at least Android 9.0?
Thanks in advance.

I do not know what you mean by genuine, it's original and unlocked.
How do I update it via ODIN if the firmware for this model hasn't been released yet?
Can I use any firmware to do it?

Man, the firmware for that phone with Pie has been release about a year ago..
Just because you didn´t get the OTA does not mean it hasn´t been released.
Just do a search here
https://www.sammobile.com/samsung/galaxy-note9/firmware/#SM-N960F
for your country code to get the latest
Also search the forum for the latest ODIN version, and you must know if your phone has a SnapDragon CPU or an Exynos CPU if you would like to install custom roms and/or TWRP recovery
Go for it..

OP your so lucky to be on oreo I'm jealous

Better to Stay on Oreo That Update it to Pie/10

Waw.. How lucky you are.
i think better you stay in Oreo that updated it to Android 9 (Pie) Or Android 10.
IMHO, true Power of Galaxy Note 9 is on Oreo. The Multitasking menu is far usable in Oreo than Pie. The Pro Video mode is basically available on Oreo. also, you can slide the Shutter button to Zoom-in/out. Thats only on Note 9's Oreo.
Believe me, you'll regret it once you've successfully update to Pie. CMIIW

Can safely say that Android 10 OneUI 2.1 is the best software for the Note9.

When I play Asphalt 9 it gets really hot but I'm not a gamer so that's a rare event for me xd That said that's the only game which really heats up my phone so much, others make it normally warmer.
Otherwise i haven't seen any issues at all the last 4 months since I bought the phone, Exynos version as well. I'm on OneUI 2.1 since 1 month ago. I never had the famous screen tint issue that others were reporting.

Mine was stuck on Oreo too. Always said that my device was up to date every time I would check... I downloaded android 10 from some where and used patched od to install it. Had to do a lot of updating of apps when it booted up but that's how it is.

Downgrading android 10 to pie

Hello forum.
I am on the latest BTU UK version
Of android 10, but I wish to
return to pie. Do I basically just flash
A pie stock ROM? I Want to
Use the light ROM or galaxy project ROM .... So is it straightforward?
Thank you
GARY

Check current bootloader version if it is higher than on old pie firmware than it is a no go otherwise just use Odin

So...SK1 wouldn't work???

Bootloader version is 5th character when you count back from end of build number. It will be S4 or U4..the number is the bootloader you are on.

Did you manage to return back to Pie?
And do you mind me asking why you didnt get on with Android 10 UI2?
I'm on Pie UI1, and I'm concerned about updating and 'breaking' some of the current features that work on my Note9
Thanks

Android 10 takes a bit of getting used to (so does Android 11 DP1 on my Pixel 3XL) -
I downloaded Odin versions of pie SK1 and latest android 10 build, as well as the twrp for the different OS, have gone back and forwards between 10 and different roms on pie, and no problems, as long as you got backup, odin and a stock rom

I tried downgrading to pie Odin reads everything but doesn't flash. It says write failed after a long time. I am using Alienware laptop I'm not sure if there is something I'm supposed to do. Any ideas. Thanks

This is best your note 9 is on a newer bootloader. it is not possible to flash the old bootloader required for android pie

I was able to downgrade my Note 9 from android 10 to Pie pretty easily, but that was with the 1st release of android 10 for the Note 9. I think the newest version of android 10 has a different bootloader. So you would need to unlock the bootloader before you can downgrade to Pie.

that would be because youre on bootloader 4 and thus can downgrade to the latest pie version on bootloader 4

First, sorry if my english is not the best.
I have buyed second hand an s9 note, wich was updated to android 10 Pie. I need call recording to work, i have call recorder pro, but as you know gogle removed ability to record calls. I want to downgrade to oficial oreo 8.0 or 8.1, but on odin 3.13.1 in download mode i get binary error ( bootloader locked). I can not understand policy that samsung fore user. If i have an pc and want windows xp on him, what is the problem ? If the phone has initiali oreo, why is forced the user to update and cannot revert back ? I am deeply disapointed about samsung methods. Why you pay past 1000 Euro (on release) on something that canot help you in the long run ? Why samsung dont listed to user need to revert back ? Internet is full of thread with this problem, is full of thread that promise to show how to downgrade to oreo but most of them did not work. I am not a geek of phones, i have some background in it repair shop, but that is all i know.
I need desperatly to get call recording, as i need in my daily work, tried more than 10 apps in the store none of them working good (only my voice is recorded and no asigned contact number)
Is there a way to officialy downgrade to oreo or achieve call recorder corectly in android 10 ? My phone dont have knox triped (any way is out of waranty). I fear to root because i use internet banking. If i go to a samsung service will be able to help me ?
I am in romania (europe). I DON'T care if we put an firmware from india (readed that in this country work call recorder,) if language for phone is at least enghlish, and all other apps work well.
Please help me !

You are on latest bootloader so Downgrade to oreo is impossible once you upgraded to android 10.
One thing you can do is to root your phone and flash custom rom that supports built in call recorder in dialer app.
Alexis rom 1.4 has built in call recording feature so you can have call recording working with android 10.
But you have to unlock bootloader and install Twrp recovery to flash this custom rom.

Many thanks. Although i do not want in principle to rooting, seem that is the only way. I feel so cheated by samsung and google. I have some background in pc repair and here you can put whatever os do you like, my hardware my software. But this android makes me crazy, and hammer my liberty of actions. It is real unfair that canot revert to oficial rom, from the begining of product life, I am sory becouse maybe i had to make my leson before to buy this pretey device.
Thanks a lot, Is it posible to downgrade in cascade, to 9 and after to 8 ?

No it's impossible even to downgrade to pie because you are on latest android 10 bootloader 5 and pie is on bootloader 4 & 3 and oreo is on bootloader 1 & 2 so forget it.
And even if you downgrade somehow to pie the call recording will not work on pie either it's only work on oreo or earlier android.
Only way to get call recording is to unlock bootloader and install custom rom via Twrp recovery.

Some banking apps and samsung apps dont work with rooted phone such as samsung pay and some knox related apps but with magisk root you can hide root from banking apps .
If i ware you i won't risk to root my phone just to get call recording.
I rather buy a cheap used or any budget phone with earlier android and use as my secondary phone to get call recording.
But if you flash custom rom you will get lot of features that are not available on stock firmware.
The developers put lot of effort to make this roms and enabled lot of cool features that Samsung has disabled.

What? You had an update notification for OneUI 2.1 ?
It's not supposed to be out yet: https://piunikaweb.com/2020/06/06/s...e-ui-2-1-update-to-release-mid-of-this-month/
About call recording I'm pretty sure it's carrier / country dependent so that's why some users have it and some don't.

Install samsung phone info. Most of the firmwares are multi csc. If I'm not mistaken, you could switch to other csc easily as long as your csc listed in the firmware. I'm not sure which csc(s) have call recorder though.
I myself with custom rom, so I'm not sure if stock has call recorder.

You can try flashing the Indian firmware as I too saw that topic on Samsung forums but there's no guarantee that it'll work. If not flash some custom ROM and it'll work then.

SOLVED
Finaly solved my problem, with help from some info and users on romanian softpedia forum.
First, download latest oxm firmware for your phone if exist (for my phone s9 note 8gb 512, exynos it is).
Second, flash phone with this firmware.
Last. Put an thailand sim in your phone, reset to factory with new sim (this make your phone to accept new csc). i have now (02, first, buyed from uk, rom, and thai). After that restart phone and change sim with your curent sim carier. If everything worked, native cal recording apear. As a plus, cal recorder pro working now behalf cal recording, wich is very handy, becouse it has a lot more options.
I am not a geek, but i was desperete, suficient to long time find a way to achive but worlds, a good phone and call recording.
