block internet app access by deleting permissions - Android Q&A, Help & Troubleshooting

good morning, I need your help.
I'm trying to understand if it is possible to delete an app's internet access by deleting the permissions.
so I intend to remove access without having to install other apps.
do you think it's possible?
how can I do?
os: android 9.0 with root!

Even with root access, you cannot do this without installing another app.
There are many apps that help you block internet access of apps, like NetGuard NoRoot firewall. Try those.

[Q] install apk as system app

Is there a way to install an apk as a system app? I want to 'unroot' a device but still run an app that requires root access. I'm unsure of how this can be done, any advise would be very much appreciated!
Thanks
I know that the Z4 root app has an option for temp root functions which goes back to an unrooted state once you reboot.
My guess is that you can run that, place your apk in the appropriate system folder, install the apk from there & then reboot.
But again I'm not to sure if temp root functions work on our G-Tabs & if it does if it's as simple as I explained. Worth a try I guess.
Again I'm assuming that your not already in a permanent root state. If so then you'll have to unroot completely first & then try what I mentioned above.
Unless someone has an easier method?
convert user apps to system apps

Titanium Backup Pro (paid version 3.8.1 and higher) has a function that allows one to convert user apps-->system apps (as well as system app-->user app ... though this sometimes causes initial FCs, which generally disappear with reboot).
Not sure if the effect will remain after unrooting.
Just to clear up a bit, not because an app its on /system it will have root access. If you want to run an app that needs root, you need root, thats it. You cant unroot and use the app after that.
So, no you cant do that. Its 2 different things installing an app on /system than having root for an app.

So then how do proprietary apps like Sprint Nascar (as an example) run on an unrooted phone?
Why would Sprint Nascar need root permision?

It probably doesn't or it might I have no idea. The op never pointed out which apps he wants to use.
However & this is a big however, as I have no idea which apps require root access, one has to assume that any of the preinstalled apps that come on our G-Tabs do in fact need root access, yet they can run on an unrooted device. Again I could be wrong.
That being said, how does one go about determining which apps require root access?
Thanks for the replies guys. The issue is supporting proxy servers on unrooted devices. There are several proxy apps that require root access as well as a kernel that supports proxy. If the proxy app were installed as a system app, would this have enough rights to access the kernel as required? I don't know enough about this but was led to believe this might work if it was running as system. Same for apps that use CIFS, like mount manager. I guess I'll give it a try and see what happens...!
Like I said, being installed on System doesnt have anything to do with having root or not.
Im 95% sure about what I am saying.
edit: I confirmed it..so 100% sure, if the app needs root, you will need root no matter where the app is installed.

superuser is dead?

hi. why after root google maps can't work? I have monit that this app need data transfer. super user is blind-don't see apps who need root. and sometimes crashing. I see that process called com.noshufou.android.su doesn't react. and two options.

SuperUser not asking for root access in Nox App Player

I was opening up a few apps that require root access after Nox updated to 5.0.0.1 just to find that they freeze up. So I close out these apps and try to restart them and that is when I am presented with a "Root access is required to run x" and SuperUser is not asking for root access.
Root is indeed enabled in Nox, and since SuperUser is built into Nox, there is no way to clear its data or anything. I am at a roadblock
does anybody know what the problem could be or how to fix it?
Try bluestacks or leapdroid, because there are the best android emulators for root.
nox already rooted
go to sittings and check on root and save sitting + delete super user app

If your device has root access, you can remove King root with other applications or from the King root settings. Uninstall the application with link2sd. If you can not delete the application, you will have to install the stock rom.

Thanks , but after three dots -> i have option to uninstall OR convert to user app.
Under both i get the same error:
"Link2SD could not obtain root access.
Maybe as i formatted my phone, i am no longer rooted and hence the error.
Also, i tried disabling Kingroot from phones builtin "Applications manager" and yes it seems disappeared from my App list on phone, Is it safe to say its no longer working on my phone even in background ?

The application that you deactivated will not run again, but if it really was malware, it probably installed other malware applications. I recommend you to do a complete analysis with several antivirus programs starting with Dr. Web.

Hiding root

Hi, I hope I'm located rigth (please don't judge)
Forvarious reasons I definitly need to root my phone.
But on the other hand, I gotta use a banking app, which is able to detect root and crashes on startup.
I use Magisk Manager to hide root from apps like Snapchat and that works without any problem.
I started decompiling the banking app and even found the line where it chrashes, but couldn't make my way to the place where it really detects the root.
Does anyone have an idea what I could do. Any better method to hide root. Any ways that apps detect root, so I could try to find it in my banking app and find a method to hide.
Thanks for any effort. Feel free to ask anything I forgot
