Galaxy Note 9 Disable Security Log Agent

How to Disable the Security Log Agent Notification on the Galaxy Note 9

After you install TWRP on the Galaxy Note 9 the Samsung Experience software recognizes that changes have been made. Specifically, a service called the Service Log Agent notices this and warns the user via a notification about unauthorized actions. This notification will constantly come back unless we use a free application to prevent it from happening.

Some OEMs are okay with letting people modify the software on the smartphones they sell to customers. Some will limit various features (like Samsung does) if there have been any modifications made. But then there are some (Samsung again) who may want the user to be aware that such changes have been made. This is particularly useful if you bought a used phone.

What is the Security Log Agent?

Samsung does want to make sure that you are aware of any major system changes that have been made to the Galaxy Note 9. Samsung isn’t the only one who wants to make their customers aware of these changes but most of them just have a text message that is displaying during the bootup process. Samsung loves doing things differently so they do it with a system application.

This system application is called the Security Log Agent and it sits in the background constantly monitoring your device for any such changes. For someone like you or me who have purposefully installed TWRP and/or gained root access, we don’t need this notification sitting in our Notification Shade. But again, if someone bought the phone used then they may not be aware of the changes.

This notification tells you that “authorized actions have been detected,” and that you need to “restart your device to undo any unauthorized changes.” Installing TWRP isn’t something that can be undone by simply rebooting the Galaxy Note 9 but we can uninstall the application that is displaying this notification (this method does require root access).

In the tutorial I wrote about how to install TWRP on the Galaxy Note 9, I listed some of the benefits that we get along with having TWRP and Magisk installed. Granted, this notification is a result of having those installed so it’s a bit of a catch 22 here, but still. Being able to uninstall a system application thanks to having root access is incredibly useful.

There are many, many ways that we can go about uninstalling the package that creates this Security Notice notification but I found this method to be the easiest. That will always be my goal here at Android Explained, to show you the easiest way possible to get something done. I know there are a lot of people who are intimidated by ADB/Fastboot and the command line interface.

Why is Samsung Annoying us With a Notification?

I wish I could answer this question. Smartphones from companies like Google and OnePlus display a warning message during the boot cycle. I’m guessing that Samsung did some data collection and found out that people ignore things that show up while the phone is booting. Whatever the reason is though, this is what Samsung has chosen so this is what we have to deal with.

Remember, this is all about Knox and the security protections that it adds to features of the Galaxy Note 9. So, now that we are no longer protected by Knox, we see errors pop up when doing certain things (like trying to create a Secure Folder). So it’s possible that this notification is a reminder for those times when people are confused by those types of errors.

Most OEMs also choose to not show a notification when the phone is in Safe Mode either. However, Samsung does this too so I guess all of this is par for the course.

Will This Make the Galaxy Note 9 Any Less Secure?

Since we have already unlocked the bootloader of the Galaxy Note 9, and then we installed TWRP on the smartphone, there isn’t much else we can do to make the phone less secure. There are enough malicious applications out there from untrusted sources. People are enticed into installing free versions of premium applications and games all the time.

Your bootloader can be locked and the phone could not have root access and those malicious applications can do a lot of bad things to your device. This is why there are so many different layers of protection when it comes to sideloading applications. We have the unknown sources toggle, the Google Play Protect scanner and the verify apps feature.

All of this isn’t even taking into account that a phone could have an unlocked bootloader or TWRP installed and rooted. My main point here is to not install applications from untrusted sources. It’s pretty easy to jump on a forum like XDA-Developers and ask if an application or source is trustworthy. I would say that places such as XDA Labs, APK Pure, and APK Mirror are all trusted sources.

Use Your Common Sense

These sources aren’t promising premium apps and games for free though. So that’s a big sign that they are trusted by the community. Just use your common sense and you will be okay to install thousands of useful mods and apps from those trusted sources. I also want to tell you to be careful with what you choose to uninstall with this application.

Just like I showed you, we can easily uninstall a system application in a matter of seconds. If you were to uninstall a vital system application then it could prevent the Galaxy Note 9 from booting. It could prevent certain apps from opening or you could lose access to even more Samsung applications and services (like we lose when we tripped Knox).

You may be okay with “debloating” the Galaxy Note 9 and doing so could save you some battery life while also increasing the overall performance (by a small amount). Again, just use your common sense and at least create a backup via TWRP so that you can restore from it in case something goes wrong.
