The only known fix is downgrading back to Oreo if it's even possible.

First THANKS for the answer.
Second is there any chance at future system updates to add us a choice to disable that?


This "option" it is happening to all region samsung galaxy s8 & s9 or only at European mobile phones samsung galaxy s8 & s9?

No bluetooth, no headset.

And I don't know the process.

So you say that I have to downgrade to root? Well I don't know. Also I'm still doing research about what tools the Xperia users do use. It would be useful to do some analogy to Samsung devices since I'm more familiar with these.

Hello there, well I am a little rusty but in order to install TWRP and of course root you need to :
1- unlock bootloader on Sony web https://developer.sony.com/develop/o...ck-bootloader/
2- Flash using Emma https://talk.sonymobile.com/t5/Andro...-p/307318#gref
3- Flash TWRP image https://forum.xda-developers.com/xpe...ia-zr-t3744868
https://www.xda-developers.com/how-to-install-twrp/
4- To reboot on recovery with button ...... hold power + vol up or down , or "adb reboot recovery"
Done, you have TWRP to flash magisk ( root ) flash ROM etc

OPEN BOOTLOADER WIPES ALL YOUR PHONE, BACKUP WHAT YOU CAN

PS : I hope you understand my english and good luck

Thanks for helping. I'll give it a try and I'll reply. Hope I can backup this stock rom and settings before rooting. Also hope I can find an unbranded stock rom. Write you back about.
Pd. It's ok about your English I can understand.

I can't answer that for sure, but I think it's a good bet that a future update will address the issue. My experience with Samsung devices in recent years, has been very positive. They do seem to keep up on fixing bugs. As far as I could find, it is affecting all variants of the S8 and S9. (Haven't seen any mention of it happening on the S10 yet.)

I have an idea that might lead to a fix. Somewhere in your system partition, most likely /system/etc or /system/csc, you should find 2 files that would be worth checking for a "max starting volume" setting, or something very similarly worded. One is the feature.xml and the other is literally named, "other.xml" which is usually in csc.

Additionally, it would probably be worth checking out your build.prop(s). Just remember, that there's at least 3 prop files. One in oem, vendor, and system. You might have something like, audio.safemedia.force=true in there, which would definitely cause the problem you have. Actually, I'd check those first. They should be smaller and easier to skim through.

One last thing I can think of, is checking your settings_system.xml, settings_global.xml, and settings_secure.xml. All them should be found in, /data/system/users/0/. You can also use a terminal app or adb to list them with,

su (or "adb shell")
settings list secure
settings list global
settings list system


I would definitely check those last though. They're always pretty big, and painful to read through. I wish you the best of luck! If I can find anything more about it, I'll definitely drop you a line.

Why is this happening and how i can solve that?

I want every time i power on the mobile the volume will me at max.

Everything that others have said, and also maybe have a read of the post with a link https://forum.xda-developers.com/sho...e#post76341856

I would not be surprised if Samsung explicitly made the choice of resetting the volume to help users get their audio working again by rebooting the phone. I would also not be surprised if they do not enable rebooting the phone with an unsafe headset volume. I know custom ROMs I have used give such an option (with a warning and user confirmation), but a big company like Samsung may be a little more careful regarding possible legal ramifications. For example, my car is speed limited electronically by the manufacturer.

Thanks but unfortunately third party app lock is useless because there's a slight delay between clicking the icon and locking it by blocking with overlay. This delay can be easily exploited by my kid: he keeps clicking the icon and crawls his way through.

In fact I had blocked Security using the parental control app (Qustodio and Screen Time Labs), but he exploited that delay.

So I would love it if there's a built-in method to hide, lock or block Security app.

When you flashed your custom ROMs, did you factory reset and wipe cache before rebooting the device into system?

When you flashed your stock firmware, did you boot into stock recovery and choose the factory reset option and then wipe cache partition?

Another thing it could be is if you are installing too many apps or storing too many files and you aren't leaving enough empty space for your device to function correctly. If this is the cause, delete some data or store it in another location to free some space.

When I was installing custom roms, I wiped everything(both caches, system, data) and formatted data. After flashing both rom and gapps, wiped cache and booted. When I was installing stock rom, I wiped everything and formatted data with twrp, then flashed rom using ODIN. Both internal storage and sd card have more than 10 gb free space each.

It´s a funny thing; security apps are incredible unsafe and easily mocked or removable, then to post I found that the data can be deleted for any user.

Maybe you´re not familiar with but probably the best would be unlock bootloader, root it and installing a custom rom (I ever do this) in this way the app Security Center is easily controlled. Or installing a different rom by i.e. an AOSP where this app is not present.

You also can delete it using adb but probably this get in other troubles so is an in-built system app on Miui firmware very dependent of. For this It has to be considered which other apps work with so they have to be also deleted to not cause conflicts.

Finally freeze it, hide it or disable it is not an option when someone else is determined to break with. Your last resource would be delete it then to unlock it, root it but again I don´t want to anticipate before you try it but probably device will have a back-door that can be exploited for a smart user stubborn to break the rules.

Would you be kind to point how to do it? Because I think it seems like the safer method. And that way I can also keep the built-in App Lock.
