Hi.
Bought an unlocked Samsung Galaxy S3 LTE (GT-i9305) but found out it has this SuperUSer app.
Does this mean the device is rooted? Will i have issues in installing it with the official Android 4.2.2 or 4.3 (if it comes) to the device?
Or can i install 4.2.2 or 4.3 with much ease? (As i am not famailiar with rooting a device)
Please advice. Thanks.
Doesn't exactly mean your rooted but it is a root app that you MUST have . without it your not rooted basically...
If you install on other device it will do nothing unless you've actually rooted the device.

Superuser is the app that manages what apps on your rooted device have access to su. Apps that are granted su have elevated permissions and can modify just about any part of the system. The app was originally written by zinx, and I took it and made it much more useable. The app consists of two parts, Superuser.apk and the su binary.
Superuser.apk runs as any other app and gives you, the user, a place to see what apps you have allowed or denied, as well as view a log of what apps have used su when.
The su binary is what other apps call when they need superuser rights. The binary checks the database maintained by Superuser.apk to determine if you have already granted rights to the requesting app, and if not tells Superuser.apk to display a prompt asking you for permission.
My S3 LTE is currently running Android 4.1.2. Still waiting for the official 4.2.2 (or 4.3) update from Samsung(UK).
I haven't noticed anything unusual or asking for a "SU permission" in installing an app.
So, my question is:
Do i delete the app or not?
Will it "block" or not allow any future OS update from Samsung or Google?
Please advice. Thanks.

In the past I read a thread from someone claiming that he had
Appbrain App Market installed on his phone which is a Non-Root app the last time I checked, Well anyways he said that he was Receiving Popups from the app to Grant it Superuser Permissions.
I really Didn't think much about it until now when I Received a Popup of my own, After I Installed whatever Stupid Basketball 3D game from the Market myself...
I checked and it Wasn't a Root app, and it Didn't even show up in the Superuser app Log, even though I Didn't Grant it Permission. I just UnInstalled it as soon as I saw the Popup!
So my Question is...
What the Hells up with that? Is that some type of Virus app or some ****?
Thanx in Advance!

i'm not familiar with random apps from the market asking for superuser permission but i am familiar with the superuser app and how the permission structure/process works.
essentially, the superuser.apk file replaces your /system/bin/su binary with its own binary. the superuser custom binary, whenever any user or application executes a command using the su binary (executing a command as root) the superuser su binary redirects to the superuser application then prompting the user to accept or deny the request.
i know i have seen it is possible to spoof these requests, but it was done by a very knowledgable friend and i don't think the spoofing of superuser requests is common place or well known (might have been patched recently too).
without knowing the application's source code that requested superuser access, i personally would not trust the application unless the application stated it would need root access and performed functions which required root access. example, if the application were a game, i don't see any reason it would need superuser access.
once an application has been granted superuser access on an s-off evo 3d, it essentially has write/read access to the majority of the android partitions including the kernel, system, data, cache, etc.
from what you've described, i think you're correct in not granting an unknown application superuser access. as a developer with applications in the market, i would appreciate an email from a user who experienced such a situation and a screenshot attached would be even more helpful. might be worthwhile reaching out to the developer to confirm or ask them to explain.
thanks for posting this information. always good to know. hope some of the information i provided helps!

Yeah man I Never really Experienced a App Requesting Superuser Permission, that Wasn't even a Root App... Just Didn't seem right to me either... A Game Shouldn't need Root Access!!
Thanx for your Reply!
I recently had the same op-ups from Tasker. But since I had been using Tasker even before rooting, I denied the request.
Are there any more precautions we need to take with regards to this.

Great question. If anybody else has experience/knowledge feel free to chime in.
Regarding precautions, there are a few basic steps which I think we're all fairly familiar with as being general computer precautions. These are a few which come to mind:
1) Don't load software you don't trust.
2) Always thorougly check the permissions being granted to an application. Example, once you grant an application permission to load at startup, it now has the potential to always be running in the background. Potential bad situation: the application *could* be gathering user/system data and if it has network access, sending this data back.
3) Superuser provides a great basic level of security to protect root access. Without superuser, any application can execute the su binary now running with root priviledges and there will be no required notification to the end user. This could all happen in the background w/o a log, audit trail or notification to the user. Root priviledges, as I mentioned above on an S-OFF EVO 3D will give write access to /system, /data, boot (kernel), recovery, etc. This is potentially very dangerous and important to protect the su binary.
Important to realize, once an application has been granted superuser access, it has the potential to destroy the device or grab extensive system/personal information and send it out. This makes it essential to trust the application.
As with any type of security, there are always ways to bypass. Essentially, these three steps should help avoid the majority of issues.
On a brighter note, there really aren't many Android viruses or malicious applications in circulation. For the most part, people who post on XDA and android application developers/posters in the market have are trustworthy. The comments on Market applications are usually fairly helpful. Might be worth skimming thru a page or 2, maybe 3 or 4 of market comments on a suspicious application or emailing the developer.
I know as a developer I'm more than happy to explain any function or question regarding my applications, especially if it raises a security/privacy concern to a user.
Hope that helps round out some simple precautions!
So, my ROM comes preloaded with a root app that I've never heard of, and I want to use Superuser (and the Elite I paid for).
The bundled app came with a 'cleanup/uninstall' script, that I ran, that promised to remove itself and it's root-granting abilities.
Now, even though I've got Superuser (Elite) installed, apps are saying I don't have root.
How do I configure Android (or SU) to use SU as my root-granting application?
Thanks.
Fix permission by recovery! It should work
In the stock firmware, was it always there? I just rooted my phone and I just noticed it. I don't remember if it was there before I rooted.
Lol
Rooting does nothing to the firmware it just places the su and busybox binaries into the correct directories so that when an app requests root access, another app like superuser or supersu is launched to grant that access with said binaries.
therefore, yes it was there before.
Hi, when cwm SuperUser done a update to app and binaries the root not work in my device, can someone give me SuperUser cwm.apk v0.9 or some work please, i searched but I didnt found

Very thanks for answer, but the link is a .zip and I want an apk or can I put it (.zip) with default recovery and not have problems?
Extract that zip, apk is in there
Tapped from my RazR

thanks now I understand I dont knew that...but the apk is not that, I tested that app and not worked because I dont have root chainfire installed , the super user that I have is SuperUser of ClockworkMod, I need a previous version.

Look man, superuser is ROOT. Either your phone is rooted or it is not. A rooted phone can run apps that require it like ClockworkMod ROM Manager, Titanium Backup, Greenify, Wireless Tether for Root Users, File managers like Root Explorer or ES File Manager if you want to be able to access the system areas of the phone. So far as I know, there is no "SuperUser of ClockworkMod". If your phone is rooted (You will see superuser or "Super SU" in your app drawer. Here is a free app from the playstore that will tell you if your phone is rooted or not.
Root Checker
Install it and use it to see if your phone is still rooted or if you lost root somehow. If you still have root, then when CWM starts, it will ask for root privileges and the first time it asks, you will be prompted to grant it, once, for a certain time period, or forever. For stuff like CWM, root file managers, and Titanium Backup, you always grant root forever and you will not be asked again until the app updates and requires you to okay granting root privileged or not, then you grand forever and leave it alone.
If you find out you do not have root or lost your root, then you have to root the phone and the procedure is different for different devices, versions, and ROMS. For that kind of help, you have to search for rooting <your particular device and android version number>

Thanks for answer, well I thinked that too, because my phone cant use root privileges if the aplication superuser isnt installed, however with te superuser aplication my phone have root privileges but with the previous version, with actual version my phond dont have root, even the people in google play say the same "with the new version my phone losed root" and similars comments...
maybe the root version (clockWorkMod) work in this way and need the app for work.
maybe this one??? http://d-h.st/l91

Solved it? No problem
One thing that I keep reading about android malware, is that it needs to gain root access to do its dirty work.
My android phone is already rooted and I have SuperUser (SU) installed. And whenever an app runs that needs root access (such as titanium backup), SU asks me if I want to grant root to that app.
So, my question is this - can I rest assured that I won't get infected because if for some reason malware makes it into my phone (through one of the many exploits like the MMS/Stagefright thing), I will see it try to run because SU will ask me for permission, and I can simple deny it?
Yes, Lookout security recently discovered a malware that does the exact thing you mentioned.
