Sound Bug on speaker and headphones - Samsung Galaxy S7 Questions and Answers

Hi, I'm having a distorted sound while I'm playing videos or listening to music on speaker and headphones. I'm on stock MM, rooted and TWRP installed. I updated the system to 1 december patch and can't upgrate to Nougat because I'll lose the IMEI, that's what they told me so I hope someone can recommend me a fix or anything to avoid this bug because started to happen when I updated to this december version.
Greetings from PerĂº and thanks in advance.

Turn the volume down?
Or is it distorted even at low volume?

Yeah, even at low volume and ringtones are affected tho. It's a 1 sec distortion but when I use *#0*# to test the speaker always sounds great so maybe it's something with this G930FXXU1BPLB firmware version.

When you updated to the december version was that via OTA or an Odin flash?
Also lose the IMEI? Who told you that? I've never heard of updating android erasing your IMEI, sounds like a miscommunication to me.

I updated via Odin. Yeah, I lose the IMEI when I update to Nougat and I have to take the phone to a service center and they will change the IMEI in MM.

You flash all 4 firmware files (CP, BL, AP, CSC) at the same time?
Also that sounds very shady. A phone shouldn't lose it's IMEI phone updating, I have a feeling the phone was stolen, IMEI blocked, then resold, and they're using an IMEI hack to change it.
Is Xposed on the phone currently?

Yeah, a friend told me the same. This phone comes from another country and here they did that IMEI hack and that's why I lose it when I update to Nougat. I flashed all 4 files at the same time. Phone was working fine with november patch so I'm guessing I'll have to downgrade or update to another MM version and then go to the service center for IMEI hack to fix this distorted sound. I'm also have xposed installed but the sound stills there with or without xposed installed.

You could note down the IMEI that works, upgrade to Nougat, put Xposed back on, and use an Xposed module to set the IMEI back.
I assume an Xposed module is what's doing it right now on MM?

They gave me the phone just rooted and oem unlocked on developers settings, once I disabled It and a FRP error was showed on boot. So tooked to them and told me to not to disable It and not to update to Nougat because I will lose the IMEI.
You think that updating to Nougat via Odin and setting the IMEI that it's working on xposed will do the job?

In theory yes, but honestly if I were you I'd just be asking for a refund and buying a new phone. Way too much nonsense for a phone.
Do a full backup in TWRP with everything ticked, if anything goes wrong you can restore that and it'll be back to the way it was incl. IMEI - so you won't have to take it back to the centre.

Ok, thanks! Maybe You know a xposed module that could help me with it?

I'm only aware of one personally https://forum.xda-developers.com/xposed/modules/xposed-imei-changer-t2847187

Probably just a software bug that could be resolved by downgrading to an earlier version of Nougat or MM (depending on which firmware you are on).

I wouldn't trade my S7 for the 6P, it's just not worth it really. I think Global versions are marked as Global in Samsung's repository

maybe backup the EFS and restore it after installing nougat(?)

Can anyone help me downgrade g920i 6.0.1 to 5.1.1 without flashing stock or without losing my data.?
AmazingAura01 said:

That pretty much depends on the version of the phone, for example Vodafone phones have a custom bootloader, so it can't be easily modified, and even if you successfully flashed another bootloader, most probably you'd trip knox, in the best case, or brick the phone... Bootloaders are always very tricky...
I'm not sure of the model number in that case, I think it's G920F/25F (S6/S6 Edge).
In my case I have a G925i, and would love to know if it can be downgraded from Android 6... I don't have the latest patch yet, I didn't want to install it because I want to eventually root this phone without tripping the blessed knox thing.... I recall that PingPongRoot can root the phone without tripping knox, but I'm not sure of the android version that it works with.

There shouldn't be, not as far as the User Data is, as long as you don't wipe the /data/media partition, which shouldn't be the case when you flash stock FW. What is lost however, is the applications, those are lost along with their internal data, like SMS, Contacts (if stored on the phone), MMS, Whatsapp chats (recent ones at least if you didn't backup the latest chats), email app (if you use the stock one), saved games (if local), etc.
so what is the solution?
Yeah man I figured it out. I'm back on 5.1.1 now when I was on my s3 flashing stock would erase the whole internal storage. And coz s6 doesn't have an SD card I thot my internal would be wiped

Use smartswitch emergency recovery , samsung have put in place some issues with the Bootloader, moreso if you're on a newer bootloader then you cannot install a firmware which has a lower bootloader

When you downloaded your firmware for odin, was it the very newest update? Or an old one, I've noticed some older firmwares fail to flash due to being on a newer bootloader

Hey, so I have the bootloader problem too and I think we have to wait for the nougat update for the type of phone you have. I have a galaxy s6 tmobile so I think I have to get nougat and flash that when it comes out for tmobile. You have to do the same I think but for now Im gonna send it to samsung and act dumb. Hopefully maybe they fix it and send it back. Do you think they will accept my phone though? It was rooted and had nemesis rom. for nougat port from s7 edge. Also current binary is: Samsung Official. System Status is: Custom. They can see knox is tripped since the counter is void: 1.

Hey, it depends if you have warranty on the phone or not. If you have warranty, it will not cover your expenses because it's void after unlocking bootloader and rooting. If you don't have warranty and you are paying them anyways, they should have no trouble accepting it. Who would deny taking money. I hope they can fix it for you and I'm sorry we couldn't figure out how to. What you said about Nougat is true. I have checked that information as well. There is no Nougat for TMobile yet. We just have to wait. Again, in the mean time if I fix it, I will post my solution here.

Samsung S7 not receiving updates

Hi guys, I bought a Vodafone-branded unlocked S7 here in Ireland.
Never used it with Vodafone and I've never received any updates for it.
OTA, Smart switch and Updato they all say my device is up to date but I can see there are more recent firmwares for my CSC.
Here are my details:
PDA: G930FXXU1DQEI
CSC Version: G930FVFG1DQE3
BASEBAND Version: G930FXXU1BPJJ
CSC Code: VDI
Am I missing something or is it possible that under VDI there are more update channels and my phone is not supposed to receive the other updates?
It's working fine and everything, I'm only concerned about security patches to be honest.
Hope you can give me a hint.
Cheers guys.
Boot into download mode and double check it is definitely the G930F
If it is, then just flash the latest firmware with ODIN 3.12.3 or newer

If the device is showing as "Custom" system status it won't OTA
Otherwise no idea, and yes just use HOME_CSC, it'll update it as if you got an OTA

Thanks for your help. I guess I'll end up flashing the firmware manually. System status is showing as original BTW.
Any chance I might have screwed up accidentally denying an update once and losing the "updateability" of my device forever? Although it's weird Updato is detecting my device as up-to-date too. This story is really weird to me.
Thanks again anyway!

Actually it's usually the other way around, people trying to deny the updates and asking for help to permanently disable them, so it's unlikely you broke it
Possibly just a bug of some sort, or the firmware you think you are on is not the actual firmware?
What security patch does it state in settings > about > software info > scroll to bottom
The updato app is getting extremely bad reviews lately so I wouldn't trust that anyway
A lot of people update manually, this isn't the first case I've seen with your problem either so I wouldn't worry too much, just flash it yourself

Security patch level is May 2017.
The firmware the phone says I'm on in the software update section reconciles with what Phone INFO detects which is the firmware released for VDI the 2017-06-11 on sammobile.

Yea definitely a strange one, should be seeing an update
Could be anything though, some change within the OS that's not reporting something to the update servers correctly
The flash should fix it, if not, backup and factory reset for the next OTA, or just keep flashing manually

You can test this by borrowing a Vodafone sim.
Or better just backup and flash an unlocked stock Rom to your device.

Tripped knox is forever. There is a fuse that blows on the phone. That said, there are workarounds on rooted phones (you might as well stay rooted). Try looking for edits for the build.prop to restore functionality to Samsung Health and other affected apps. Dr Ketan still makes ROMs I believe and should have something for you.

I don't want to be rude, but your question was answered already. You can't untrip the know counter. It's an actual fuse, that physically becomes blown. This isn't a software setting, but an actual, physical fuse.
It goes back to the days of people using exploits, and in rare cases would damage their phone in the process, but the phone worked enough to relock the bootloader. Then the person would send their phone back and blame it on the manufacturer. So now Samsung decided to put in an actual fuse so that if you decide to unlock it, your warrenty is permanently void.
Bottom line, your out of luck. I know any unlock would have given a warning that it is PERMANENT and that it would VOID YOUR WARRENTY. Wether you read it and ignored the warning, or didn't bother to read it, it's on you for unlocking your bootloader.

Yea I remember those days... Well truth is I haven't rooted.. I was considering it until I read the warranty part... My point is, the reason I want it rooted is because I want to use some modded applications. I researched further and found out I could use some without even rooting. So i tried downloading Spotify mod app, but unfortunately it didn't work. I couldn't get recent application for it, what I kept getting was an outdated mod app. In all it didn't work. So am asking if there's a way to use mod apps without rooting the phone. Thank you

You'll have to wait until someone mods the latest app. Or, you could just pay for Spotify. For the record, I used to use a modded Spotify, and they typically patch within a day or two of a modded apk being released. They may have finally switched to server side authentication which is why your likely not seeing an updated version. I stopped bothering because it's just a cat and mouse game. I didn't feel like Spotify was worth it, so I moved on.
I find Google Play Music is a better deal. I get add-free YouTube, and all the same music as Spotify, for the same price.
On a side note, I don't believe Xda allows modded apks that bypass paid features. There are sites that cater to such things, but I'm pretty sure it's a no-no here. They tend to support devs / companies as opposed to cheating them out of money.
Hi dude, I have 2 questions, I just buy S9+ 965U sprint unlock running U3ARH7 can I flash this 965U1's fw? and What is CSC in U1 fw? thanks

Hi, you can flash the U1 firmware on the Sprint 965U. You need to use the patched Odin linked in the OP. The CSC file included is for multiple carriers. When flashing it will read your sim and setup accordingly.
Umm what's new? The "I" September patch Odin's have been out since mid September.

The thread provides detailed instructions and the most current firmware. The instructions are new to the thread and so are the links. Didn't realize I was required to explain what was new to you.
Uploading G965USQS3ARIB firmware now.
Hi, Q. If I install the ARIB version in my U1 under att, I still can use another carrier sim right?
I'm traveling to Argentina soon and I want to know that.
Thanks
Should be fine , your U1 is unlocked. The sim card in Argentina might not set up the APN for you regardless of what firmware you're on. Personally, I would use the U1 firmware though.

I don't use the "B" revision firmwares, but there was at least one listed as a BOYD firmware. Since your already on U1 and loosing wifi-calling, HD voice, volte, etc, that might give you the best luck. Might be something to look into.

Sorry, didn't understood your response. Is that an yes besides regaining the features of HDVoice, volte and Wifi Calling?

You asked about sim swapping for traveling. The BYOD firmware makes for easier sim swapping. It's designed to populate the carrier settings when you insert a sim instead of needing to wipe your device.
As for ATT features, I believe those firmware are for the U firmware, so yes, you'd regain those features, but you'd get the ATT bloat. I don't mind the bloat personally. I just remove the junk I don't need.

Question Removing Retail Mode from S21+

Hi XDA, first time poster and I could not find a similar thread with the answers I was looking for, if that thread exists I apologize!
So basically I started a job in a retail phone shop a few months back. We have a drawer in store that has a bunch of old demo units in there that, once they have been removed from display, just sit there unused. There is phones in there from almost 10 years ago. They are never given back or requested back, nor are they logged in any way.
Well I noticed there was an almost perfect condition S21+ in there so I asked my manager if we could use it as a sales incentive and he replied saying the phones are useless because of the software on them. I said I was pretty sure you could remove the retail software and use it as a normal phone and he said if I can do that and get it working, I can take the phone for myself.
Well, I took it home and did some digging / experimenting. The phone has a proper IMEI already, you can put a SIM into the phone and it registers to the network. The problem is, the phone has security restrictions on data sharing and it does not have the playstore on it and there is no factory data reset option in the settings, nor in recovery mode.
I have tried flashing a stock firmware on using Odin which I thought worked, however when the phone restarts and you go through set up, Samsung Knox pops up and installs settings which forces the phone to set up in retail mode again with the same restrictions as previous (no play store, factory reset etc).
Any idea how to get around this issue? I would have thought flashing stock software would be the obvious work around but something on the phone forces it to install on retail mode every time.
Any advice on this is much appreciated.

Have you tried following the steps in a video such as this?
DO THIS COMPLETELY AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF ANYTHING GOES WRONG, INCLUDING BUT NOT LIMITED TO BRICKING YOUR DEVICE, GETTING A VIRUS OR STARTING A LITERAL WAR.
Everything i was able find on the subject was kind of sketchy-looking (probably because doing this without permission would probably be illegal) so I included a warning.

Thanks for the reply!
So I also came across this same video on the subject last night, it seems to be a workaround for bypassing Knox but I couldnt find any further info on what kind of state that leaves the phone in after, if it can still get official updates and such or if it triggered to eFuse that causes you to lose access to Samsung Pay and other official apps.
I'm aware this is at my own risk, the phone will sit in a drawer if I cant figure it out any way so no harm no foul as far as I can see. I've thought about rooting the device (I know this will trigger the eFuse) but I cant find any info on if that would get around the specific issue I'm having of Knox forcing the phone to install in retail settings or not so do not want to go down that road just yet.

I'd say that the Knox workaround would probably (do not quote me on that) leave you with un-tripped Knox (=e-fuse intact) if it even still is. Even if Knox would be tripped, you would still most likely be able to get software updates. But because you said that you have already used Odin successfully on the device, that would lead me to believe that OEM unlocking might already be on in which case there probably isn't any more to lose by rooting the device. On a rooted device there are instructions o WikiHow on how to remove the Knox , but I haven't personally tested them. If I were you, I'd check with a Knox warranty checker app or through recovery mode, etc
whether the e-fuse is already triggered before continuing with anything.
And if I confused you, feel free to ask anything!
With the root approach you would also have to worry about passing Safety Net, but that'll only be relevant if you decide to go with that path.

Interesting, I may give the workaround a shot when I get home later then.
So I have used Odin but it was with official firmware obtained through Frija and, according to reading, that does NOT trip the eFuse. I did turn on OHD in dev options but from what I can tell, the fuse is only tripped when you load an unofficial image onto the device which I havent done yet. I can check when I get home by booting into recovery mode and checking the warranty line AFAIK it will say either 1 or 0 indicating if it's been tripped or not.
So my issue with rooting is I dont know if I root, will the phone still install in the retail setup that it does currently. I know I can run apps or code to remove Knox once rooted, but I dont know if then just reinstall firmware and it will be back to default like I want, or if I'll then need to figure out how to get the playstore loaded, if the security issues persist etc. Also as far as I can tell to root, I need to install Magisk on the device first to alter one of the image files, then move that file back to the PC to flash with Odin, and I'm not sure I can do that with the retail settings enabled.

So quick update on this: none of the workaround videos on youtube seem to be capable of doing anything. They all rely on being able to connect to Wifi then get around the device before Knox settings apply, however on my build as SOON as you connect to wifi, it immediately starts applying knox settings and cannot be skipped.
I am wondering if this is because the version of software I flashed on using Odin was the most recent firmware, being android 12, and most of these workarounds are for android 11? Is it safe to locate the original firmware for the S21+ somewhere and flash that on to the device instead do you think?
Also the eFuse is still currently in tact.

You could flash an older Android version, but if and only if it has the same bootloader version as the current one, otherwise it won't work and might even brick your device. I am unsure though if the downgrade would help but if the bootloader versions match, you can try!
On SamMobile.com you can see older versions of firmware. Just check the bootloader version before flashing!

It's most likely as simple as comparing the bootloader filenames between the Odin flashable files for the old and new software. I could verify whether that's the case if you send the filenames for both bootloader files here. (The file that goes into the BL slot in Odin)

So the first image is of the current firmware that successfully flashed to my device via Odin.
The second is firmware from August 2021 that is on a build of Android 11. You can also see by the file modification dates.

Yeah, it seems like the current bootloader is version 4 while the Android 11 one is version 3 so these versions seem, unfortunately, incompatible.

Hi there, I can help you out! I have some experience with Samsung.
So first off, I take it this is an Exynos model? Snapdragons require the use of a paid service to get an unlock.
It seems you've flashed stock firmware before but it didn't work out due to Knox. Did you flash all the files including the CSC (wipe all data) file? Also, you could try flashing TWRP and that would trip Knox, at which point Knox is disabled due to detecting system modifications or it will try to rollback your modifications.
So the only thing I personally can think of to get rid of the problem is going the TWRP route, but this will trip the Knox warranty byte to 0x1, so think about it. There might be someone more experienced than me that might be able to help without tripping Knox, but this is right now the only thing I can personally suggest to fix the problem.
Edit: It seems like someone more experienced appeared while I was writing this! Sweet!

Are you able to enable developer options? If so, you might be able to use ADB commands to disable the Retail Mode app. I doubt they're enabled though.

With official firmware, I'd be pretty certain that you can't. By the way, please look at the latest messages as there is someone else with fresh ideas here, too.
