[Q] Do all applications get root priviliges on a rooted android phone?

Or what is the exact mechanism behind this in Android? I have been using GNU/Linux for many years so I understand the original concept and would not want every app to have root privileges.

The Superuser app allows you to accept & deny all root apps. You can also choose to always allow certain apps, but you don't have to.

I don't quite understand this. Who gives the apps the privileges. I suppose the Superuser app is only the frontend for some system service. And does it work as a white list or as a black list. Meaning: Does every app get root priviliges by default on a rooted phone or do I have to manually give root privileges to desired apps but the rest doesn't even realize it's on a rooted phone.

By default, apps are denied root privileges. If I restore an app that runs as root in the background -along with its data - the app won't work until I launch it & grant it superuser permissions. Droidwall is a good example of this. Droidwall works by denying or allowing 3g and/or wifi access to apps based on your input. It does this by changing the iptables. If I flash a new ROM & restore with Titanium Backup, I usually forget that Droidwall isn't doing its job until I notice ads in an app that isn't supposed to connect. Once the app is launched & I choose to apply the rules, Superuser prompts me to allow the changes. If I do not make a choice within 10 seconds, SU automatically denies the root request.
In short, an app will never run as root (aside from superuser itself, if that counts) without you first allowing it. Also be aware that most everyday apps will never ask for root access as they don't need it to run. Only apps that are making changes to the system (reading or writing) will need root access. As far as accessing your contact data & other stuff you may worry about, any app can do that if it has permission (not root) to do so. When you first install an app, you will see a list of permissions - usually an app needs those permissions to run and there's nothing to worry about.

OK, thanks I understand it more now. What would happen if I didn't install Superuser. Is there a built in daemon for superuser privileges?

Don't fight the powers that be. Install superuser. You need it.

I'm pretty sure you'll get error messages from most root apps. I could be wrong, though. Next time I'm about to flash a new ROM, I'll remove Superuser after I do my backup, just because I'm curious. I'm pretty sure that Superuser or an alternative - if one exists - is necessary. I know the ability is there in the os, but I would think that it would need some kind of vehicle (such as an app) to relay the information. I certainly hope apps wouldn't automatically be granted root privileges, but I'm not sure. It's an interesting question, though.
Roms come pre-loaded with Superuser, and any auto-root method does as well. You would only be without it if you root manually, stay on stock, and choose not to push the app. Or, I guess, if you choose to remove it.

[Q] When an app get root access, what can it do?

Hi
I recently rooted my phone and started using a few "root only" apps.
When I look at app permissions and let's say it example says that it can access "Phone" and "Other". By other it means root.
Does that actually gives it permission to anything? So if I accept the permissions "Phone" and "Other" it can actually access my camera too (just an example) or do I understand the root access wrong?
Thanks in advance

what i understand if an apps ask for a root permission, the apps will ask for the permission to read/write in a secure area, eg : /data, /etc
It is different from the permission of using camera, message, etc like when we install apps from playstore.

Thanks. Was what I was curious about. As I understood root, as the app could do whatever it wanted to.

No. It is not as you think. By allowing an app root permission, it means you're allowing it to do more than controlling limited applications. It can do more than that. And dont worry it wont damage your phone because everything has its limit but yeah be careful of what you're doing as sometimes you can risk your phone if you(not by allowing an app root permissions) but by using it after giving it root permission. So be careful and know what you're doing.
Please press the thanks button if you think I helped

[Q] Looking for a way to make an app think a device is not rooted

I have a certain app that I need to use that will not run on a rooted device. My root app is SuperSU, and by disabling superuser in the settings the app will run, but I can't make it work without disabling it. It doesn't even give me a prompt to ask for root permission - the app must just be looking somewhere for the su binary or something.
Is there a way to make an app think that a device is unrooted without disabling root access?

Xposed framework with Root Cloak module. It doesn't always work, but it often does, so give that a try.

[Q] SU binary exists but no root access

Hi,
I have a banking app refusing to run since it thinks thatmy phone (Nexus 5 running 5.1.1) is rooted. Only problem is that it's not. Or at least i think so....
I have understood that the banking app concerned checks if the phone is rooted by checking for SU binary in system\bin and system\xbin, and fair enough, by xbin contains the SU file. I was rooted on 4.4 (or 5?) using towelroot. The bootloader has been locked all the time. I never rooted on 5.1 and above since I didnt want to wipe, and as it didnt matter much to me.
My questions are
1) Can I restore the root in some way, given that the SU binary exists without wiping the data? I tried Superuser app but naturally it failded to update the binary.
2) Can I delete the SU binary somehow without root access? At this point i only have read access to the system\xbin directory.

Every ROM has su in it, afaik.
You might have a hacked su in /system/xbin since 4.4, even though 5.x changes might have blocked that root access. Be advised that there's apps that can cloak root from apps.

So even stock ROMs contain the SU binary? I only read somwhere that this is how tha apps checks if the phone is rooted or not. I'm aware of the cloaking apps, but those require me to be rootad, right? Som my problem root continues: I dont wan to root (or should i say wipe data) but the bank app wont run since it says that the phone is rooted, which it's not...
EDIT: I just checked on my galaxy tab s, and it does not contain anh SU file in bin or xbin.

root rights without rooting

I've got hope. The GSAMBattery app said it needs rights to display more data. If you have root, the app does that for you. If not, you should enter this command:
adb shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS
The way I see it, it simply means that I'm granting rights here that I could otherwise only do with root. Now the question: Is it possible with ALL rights? I would need the superuser for the App Automate, so that it can automatically move my device into the flight mode and out again.

Try this
You can use Magisk root and use Magisk manager to hide root status from your device to use all applications.:laugh:

Thats not the point. Huawei doesnt give away unlock codes anymore (dont know why) and I also want future OTAs. So actually rooting is no option.
I just wonder bc the line above IS some kind of acting as root. So isnt it possible to gibe rights to other apps the same way?

Is it not possible? Then why did it work with the battery app?

The command that you used is not the same thing as root permissions, you merely granted the app permission for a certain action. No, you cannot use this methid to acheive the sane thing as full root permissions for all apps.

I dont want to do a full root permission with this command. The app Automate need "superuser" rights for putting the device in flight mode. I only want to grant that one for the one specific app.
