Hi Liam. Same happened to me.

Did you find a solution? I suspect is may have something to do with Bluetooth/wifi antenna... I tried to look into internet for schematics or something like this, didn't find any.
[Moto 360 2015] bluefish196:
The antenna is that sheet of metal paper around the case, it can get loose when putting it back.

Look for a full tutorial that includes the display and try again, if it was damaged you can try with a piece of foil to increase the surface. I have done this to notebook wifi antennas.

I like the possibility to make my phone emit a sound when I connect the charging device. But unfortunately, the system doesn't suppress these sounds when "do not disturb" is activated.

I noticed this behaviour on several different devices and on different Android version, that's why I put my question here, as a general question.
[Samsung Galaxy Note 9 Questions & Answers] Amr Mohsen:
i just upgraded my note 9 SM-N960F from dutch 8.1.0 to German 9.0 pie via Odin . and to be honest im so disappointing with this UI and the whole update i was wondering if is it still possible to downgrade back to Oreo again ???

thanks alot
[Samsung Galaxy Note 9 Questions & Answers] joedellosso69:
I think that it should be possible with Odin but honestly I never done it before so don't know. By the way, is the black mode feature implemented it this version of Pie in the toggles or in settings ?

Because I read someware that the initial version of this black mode or night mode or however it's called is not fully implemented like the final version should be.
[Samsung Galaxy Note 9 Questions & Answers] Amr Mohsen:
toggles and settings both of them in night mode , but its not stable i have the feeling its slower my phone down some unknows issus
[Samsung Galaxy Note 9 Questions & Answers] joedellosso69:
First try clear cache in recovery mode maybe can resolve. also try to update apps with play store or with galaxy apps because some apps must need an update to the pie version.. After that if all is worthless, maybe a factory reset will resolve Sometimes corrupted data may do this after an update specially after a big OS change like this.
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
Hey let me know if you succeed, as I’m thinking of downgrading as well. ONE UI PIE-9 isn’t all it’s made out to be Oreo 8.1 rocks!

i heard somewhere flashing wrong firmware, can make you lose OEM LOCK!! Why not try this launch SAMFIRM.EXE and input firmware from pic or try this first launch SAMFIRM.EXE and select auto to see if it picks up the firmware you need to download Oero 8.1!!
[Samsung Galaxy Note 9 Questions & Answers] dexter10478:
I have never used ODIN before and wanted to know if I need to be rooted to be able to downgrade from Pie to last Oreo firmware?

Also if doing so will cause a factory reset and will I loose the data.

Thanks.
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
No root is needed to dowgrade!! You will lose all your data! So make a back up before you proceed!
[Samsung Galaxy Note 9 Questions & Answers] dexter10478:
Will that affect Knox and Secure Folder feature in anyway?

If not, then this seems to be the Samsung approved official method of flashing firmware. Is that so?

Thanks
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
No Knox will stay 0x0 as your flashing official firmware.. Root and Roms trip Knox and secure folder S,Health etc. So you can flash away regular firmware without any issues!
[Samsung Galaxy Note 9 Questions & Answers] Birdsfan:
I'm hoping someone can further clarify the steps needed to downgrade to Oreo. I have the 96OU unlocked US version and I upgraded using the modded Odin method for US Snapdragon versions in the Guides section. I do not like the carrier bloat that was added to my phone and would like to revert back to 8.1. I went to SamMobile and looked up my firmware which I believe is N96OU1UEU1ARL1, my actual model is SMN96OU1ZKFX. I have downloaded Odin3 v3.13.1. I originally used Odin3 v3.13.1 3B patchedD to upgrade. Do I run Odin (non-patched) then input the BL, AP, CP and CSC files from the extracted 1ARL1 file and select Auto reboot and F.Reset Time only, not re-partition? Can I use the patched version of Odin if I want?

I have been looking for a step by step tutorial for this but just can't find one.
[Samsung Galaxy Note 9 Questions & Answers] TWiiTCH:
I downloaded the firmware for Oreo again. Last time I downloaded to FAT formatted SD card, should have been exFAT to accept that file size. This time I downloaded firmware to internal storage & it unzipped just fine. I downloaded both Odin3 v3.13.1 and the Odin3 v3.13.1 3B modded version, i am not sure which to use, or does this matter? I Was going to use the modded Odin3 v3.13.1 3B first. Also thanks for the idea of pulling the Sim card until set up phone so it won't immediately try to get me to upgrade to pie again.
[Samsung Galaxy Note 9 Questions & Answers] Blakestr:
Not exactly a downgrade question but hopefully this is less involved - I downloaded the OTA update file, but did not install. (just wanted to have on hand in case when I signed up at Tmobile it somehow got blocked or something). After reading the various issues, I decided to wait. But now I have this software notification and 1.6 file sitting in my storage.

I tried wiping cache but the notification to install is still there. I read somewhere that you can hit "install" and it will fail since the cache supposedly got wiped and supposedly deleted it. I'd just like to confirm here to make sure.
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
Try 3.13.1.3B first.It is not for exynos.

---------- Post added at 06:45 PM ---------- Previous post was at 06:15 PM ----------

If you downloaded the OTA file you can only delete it with reset of the phone.It's not on the cache partition.
[Samsung Galaxy Note 9 Questions & Answers] TWiiTCH:
Hi there friend, just to update you and anyone else with the Snapdragon model note 9. Today I succeeded in downgrading to Oreo 8.1 .0 November Edition esk which is Eastlink Mobility Canada. I had to use Odin version 3.13.1 3B Modded version. First I removed all accounts that would have tripped FRP and then I did a factory reset on the phone. After that I booted into download mode, connected phone to Odin which was recognized right away, I then added all the firmware files (don't use home CSC tho) to the proper file selection areas, and then I started the firmware downgrade. I should have mentioned this first but I pulled the SIM card right before I started to downgrade so that the phone would not try to update once it was powered back on. After the downgrade was completed I enabled the developer menu and turned off automatic system updates, I then clicked on software and changed software updates to manual, and then finally I went into Biometrics and security and then turned off the security updates last of all. The second last time I attempted this I tapped on the wrong item trying to turn off the security updates and it caused my phone to check for a software update which ruined my mission. Please research first which you need to click on because there are two items that look similar but one will cause your phone to immediately upgrade and the other will give you the option to turn off security policy updates. If you can figure out how to turn off all three of these options I think you will have success. My phone has been on for at least six to eight hours and hasn't had any update message yet so fingers crossed everything is the way I was hoping it would work out. I just wanted to update all those who want to downgrade to Oreo 8.1.0 and to thank those that led me through the process. Make sure you download the correct firmware for your cellular provider but this method worked for me after a few trial-and-error runs. Do not insert Sim card or connect to wifi or add Samsung or Google accounts until after all three of the update options have been disabled. MSG me if you need help. I'd be glad to share the knowledge that others shared with me. If or when I do get an update notice I will be sure to add that to this comment but the first two times I had to upgrade within the hour after downgrading my firmware and today I've reached hour 6-8 and all is great so far.
[Samsung Galaxy Note 9 Questions & Answers] BoojaBaandar:
Some clarifcation please

I'm looking to downgrade back to Oreo 8.1. I've read and understood (I hope) the process but just wanted a bit of clarification on a few things:

1. Can I use SamFirm to download 8.1 even though my Note 9 has upgraded via OTA to Pie? If so, can someone tell me how as it only finds the latest firmware for my device (which is Pie)

2. If the above is not possible then I suppose I have to download Oreo from sammobile, but when I search for the firmware I will need using my device details (SM-N960F, BTU) I get a list of about 5 or 6 variations of Oreo for my device. Which one do I need? I don't know the original Oreo firmware that came on my phone, which would probably make things a whole lot easier, so what do I do now?

If it helps any here are the current firmware details I have of my phone:

Bootloader: N960FXXS2CSB3

PDA Version: N960FXXS2CSB3

CSC Version: N960FOXM2CSA7

Baseband: N960FXXU2CRLT

Lastly, I bought my phone direct from Samsung sim free
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
1.You can not use SamFirm to download Oreo because it downloads you the latest software that is PIE. You have to search Sammobile or updato.com for the latest OXM Oreo or BTU Oreo ARL3 software.OXM is multicsc and you can use enything european csc like PHE,PHN,DBT.....with Oreo and your csc BTU is not change.As you wish.

2.This software you need

PDA N960FXXS2ARL3

CSC N960FOXM2ARK2

Hey guys,

I've been considering to downgrade Oreo as battery life is quite disappointing and WiFi Calling randomly keeps turning off (even when my phone is in Airplane mode).

I've read the last couple of pages but I am quite confused regarding the steps to downgrade.

Could someone please do a quick summary of all the main issues to look out for? It would be useful for me and others.

Specifically:

What Odin version is required? (for Exynos & Snapdragon, if it is different)

What bootloader version must I have to downgrade?

Thanks!
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
If you read this page you realize the whole operation.You can not repeat the same things indefinitely. More than a few pages and one would find someone to ask for a summary.

1. Odin 3.13.1 exynos and Odin 3.13.1.3B snapdragon

2.Exynos U2,snapdragon i do not.

[Samsung Galaxy Note 9 Questions & Answers] BoojaBaandar:
Something I forgot to ask was that if I back up my data/settings using Smart Switch before flashing Oreo will I be able to restore everything without any issues considering that I'm going backwards in OS version?

Also, do I need to remove my sd card before flashing?

Once I've got Oreo flashed and start the initial phone setup process, will the OTA update get triggered? If so, is there a way around this as I obviously don't want Pie getting downloaded at all? Please don't misunderstand, I mean while the phone was setting up during first bootup it checked for updates and I believe it installed a security patch. I just don't want it downloading Pie (since it clearly is now available through OTA updates) then endlessly bugging me to update. I'd much prefer to disable updates once the phone has fully booted. I hope I'm making sense lol

Sorry if I'm asking loads of questions but this is all new to me and I couldn't find the answers anywhere else, or maybe I'm not looking in the right places lol.

[Samsung Galaxy Note 9 Questions & Answers] TWiiTCH:
After my nightly sleep I woke up to a new version "pie" upgrade notice. I have two ideas of what the issue may be, or occured from.

1 is what I might have done that caused the issue and the other is an idea how to make sure it does not happen again. When you go into settings and then device maintenance I noticed that icon (far right) it says device security, well underneath it, it stated "deactivated" so I thought I'd better activate it to keep my device somewhat protected. I'm thinking maybe that turns on the security updates but I'm not sure if that is true or if that even was the issue.

My second comment is the steps I took after reflashing my phone and setting it all up again the way I described in the process. I have adguard paid version which comes with a firewall but you could also use netguard firewall. First I used netguard firewall and turned on the option in settings to allow blocking of system applications. After that I did a search and typed in "update" and disabled all the Samsung update packages, I learned which ones needed to be disabled by trying netguard first. When I selected and disabled one that I was sure from research that was related to firmware upgrades, it then disabled all the ones that were related to that package. There are four items that I had to block from connecting to the internet.

After doing that with netguard I then realized my paid adguard subscription had a firewall built in and I then knew which packages to block after I learned from trying with netguard first. I blocked all four from wifi & mobile data, and It is now about 12 hours later and I have yet to receive an update notice and am having no issues or bugs with my phone.

I also did not enable device security this time under system settings and then device maintenance. I will keep you posted tomorrow in about 24 hours and we will see if what I did worked. It would be nice if since we own the devices we could choose which version of Android we wish to use and not be forced to upgrade. Anyway good luck everyone, and last of all the first thing I resorted to was trying many package disabler apps but it seems none of them work on my device and I see that they have stopped working on many Android devices now. Just a little tip in case that was an idea that you had also.

[Samsung Galaxy Note 9 Questions & Answers] carlitos66:
In my case I have factory reset the phone before I downgraded back to Oreo. It was automatically done by enabling OEM unlock in Developers options anyway . For downgrade I have used patched Odin version v 3.13.1. B. for Galaxy SM 960 F international version with Exynos chip!! I have downloaded the Oreo software from Sam mobile, because it had the latest December Oreo update for my country. ( XEZ ) unlocked Czech republic. ( that's where I bought the phone ) N960FXXS2ARL3_N960FOXM2ARK2_XEZ. IZ ARc didn't open it, I had to use Total Commander to unzip and open the files. I didn't use home CSC since the phone was factory reset anyway. I have backed up all my data to Smart Switch and also to Samsung Cloud, just in case. For data restore I have used Samsung Cloud. Everything was set up more less same except home and lock screen wallpaper, I had to sign in into all apps again. Also in to my email account.

After succesfull Odin pass I have entered into endless boot loop so I had to reboot by holding volume down and power button for about 5 seconds. Then I have re booted into recovery by holding volume up and bixby and power buttons together for few moments, and then performed factory reset.

I am back on Oreo, but even if I have un clicked all automatic updates, I still have permanent notification about software upgrade, which I just ignore, until I root the phone. I hope Samsung will not automatically update my phone in which case I will have to do this all over again. I hate pie update.

I have downgrade to Oreo with Odin 3.13.1 on exynos.No problems!Why odin 3.13.3B?
[Samsung Galaxy Note 9 Questions & Answers] BoojaBaandar:
Hold on, I was under the impression that once flashed back to Oreo all I would have to do to stop further automatic OTA updates was skip any network setup (wifi, data) and once fully booted just go into the update section under settings and turn off updates. If there are any update settings in the developer menu they can be turned off same time. Then restart and continue properly setting up the phone. Am I missing something here?

I won't be using any custom roms, just flashing back the last official Oreo firmware (which in my case is from 4 December 2018).

I have the following downloaded to my pc:

Odin 3.13.1

BTU-N960FXXS2ARL3-20181217152710

Smart Switch

There isn't anything else I need, right?

I just back up my data/logs/settings, flash the firmware via Odin then setup the phone as described above, correct? Last thing to do will be restore my data/logs/settings from Smart Switch.
[Samsung Galaxy Note 9 Questions & Answers] TWiiTCH:
I'd say find the firmware that you need but if downloading from sammobile be prepared for a slooooww download unless you are willing to pay a fee. I recommend...

https://updato.com/firmware-archive-select-model

Much faster download! Look at the last 3 characters for carrier/country info, mine for example is...

Canada (EastLink) (ESK). Each carrier or country or phone model has these 3 letters for quick reference. ESK is for my carrier in my country.

Try using this app for all your phone info (in full detail)....

Or this one too, I like both...

https://play.google.com/store/apps/details?id=com.finalwire.aida64

If you read the full thread or at least my posts I must state in my final post I thought I was good 2 go after turning off all the things that can trigger an OTA update and even blocked the update packages with a firewall, but some time after hour 12 I woke up and saw the damn pie update notice again. All in all it was a waste of time on this phone. Canadian SM-N960W Samsung Note 9 6GB/128GB Snapdragon Type: crownqltecs manufacturer Vietnam, Qualcomm sdm845 chip/board. This snapdragon (all I assume) don't have OEM Unlock option in developer menu (only exynos does I believe) I Followed everything to the letter but downgrade would not hold. :(

Good luck with your trial, everything you need to know about has been posted already in this forum. Just gotta thumb through it.

[Samsung Galaxy Note 9 Questions & Answers] _Sparks:
Cheers mate for the detailed reply.

I decided to stay on Pie, as the battery life was my main concern and it seemed to improve after a factor reset. I guess even if I did go back to Oreo, the update is inevitable as you mentioned.
[Samsung Galaxy Note 9 Questions & Answers] :
Yeah this Pie stuff sucks. I did the stupid and updated. I figured since I'm getting my S10(E) this week and that I still have my rooted One Plus 6T why not try this One UI stuff on this Tmo Note 9. First I had an error screen after updating so I had to boot into Safe Mode in order to get my files then factory restart. Then I notice that my spare S-Pen, the big one and the big S-Pen that came with my Tab S4 don't work at all. I have to take the Note 9's S-Pen out then the phone recognizes my other two S-Pens. This was not the case when I was still on Oreo. I liked to use the bigger S-Pen I had when playing games and stuff because it's more comfortable in the hand.

What a waste. I'm going to keep tinkering but for now I put my SIM card back into my One Plus 6T until I get the S10(E) at the end of the week/weekend.

ETA: I just saw this setting. Why was this needed? Why did Samsung feel the need to add this setting when it was working fine for all the past generations of Notes?
