[Privacy] Modifying Permissions for System Apps - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi there,
For the benefit of increased privacy, how can I modify the permissions (such as microphone, camera, body sensor access) for system apps, like System UI or Accessibility etc?
I wish to have access to such permissions to choose what I feel is required/necessary.
My phone (G985F) is rooted with Magisk and I have already removed/frozen a bunch of bloatware but like I mentioned would like to revoke some permissions for 'system apps'.
Please can someone assist me or point me in the right direction, thanks heaps.
Andy.

Thanks for your reply. I think you may have misunderstood what I'm asking here, while what you've shared is relating to modifying app permissions installed on the phone, it does not allow modification of 'system app' permissions as I stated I'm trying to do in my post. Currently, upon attempting to do this for say System UI (a system app/service) for example - I am unable to revoke microphone permissions due to it being greyed out and saying "Device needs this permission to operate".

Its probably because those permissions are a must for the phone to operate. Somethings are just needed to make a device work.

Not exactly what you want but Package Disabler Pro can disable system apps completely without root, I tried disabling certain permissions but couldn't find a way, just to disable it completely

Theres also CCSWE app manager which also has the ability to disable system apps and i think individual processes within the app, if you know exactly what your looking for.

Any idea for apps permission control ?

It seems the App Ops cannot work properly on Firephone without root, so any idea for apps permission control?
This is an Android 4.4.4. based device, so root it, install app-ops or Xposed and similar modules.
An app like "Advanced Permission Manager" is no feasible option either, free version is limited and with the concept of this app, you would have to make more than one compromise.
"APK Permission Remover" is just as bad, because you would be forced to change the permissions each time before installing an app (same general idea, since it's from the same developer).

How to prevent apps to detecting from permission has refused?

if app requesting permissions at runtime, it's may be through API:shouldShowRequestPermissionRationale to detect that whether permission has refused, same app e.g. Alipay need dangerous permissions to read and write sdcard but i thought that permission isn't necessary, if refuse it has will not to use, but i just use it to pay, can i hack into the android permission mechanism to change API:shouldShowRequestPermissionRational alway return has granted?

I guess you could, but transactions won't work since Alipay couldn't save 'temporary' data to the SDCard.

My another phone is Android 5.1, XPrivacy has restricted access sdcard, at the same this time the Private Guard has restricted all dangerous permissions on Alipay but that no complaints and it's work fine. since Android 6.0(RR ROM, Xposed Version 85) Xprivacy can not restrict storage permissions even though i selected restrict all storage subitems.

Xposed for A7 2016

Hello Sirs
I want to install xposed on my (SM-A710FD) phone which is 5.1.1 android
This is a 2017 series.
For what do you need Xposed? I have tried it on my tablet and there is little to no use for Xposed. Maybe I change my mind if you tell me some good modules.

The problem with Xprivacy is that it is quite hard to understand. There are no community driven settings like in uBlock Origin (adblocker for pc). Nor there are options for temporary allowance. Besides, Android 6 already has permissions per app.

What is there to understand? My 13 year old nephew managed to set it up.
Android 6 does not offer this many options. Can you stop an app getting your IMEI or Phone serial details? Why does an app need your IMEI?
It comes with default settings such as location (Christmas island) IMEI 00000000 etc.
1-Install the correct version of Xposed for your device.
2-Install Xprivacy app.
3-Launch, allow Root, click on Template and set each permission request to block.
4-Reboot phone, launch Xprivacy, see if template has been applied.
5-Install an app or game. You'll get notification from Xprivacy with template applied.
6-Allow the permissions that the app needs. Eg Firefox browser needs Internet,Network,IPC,System allowed to work.
For games I don't allow any permissions and it still works.
If you need to allow temporary permissions just launch Xprivacy and turn it off for that app.

Blocking everything isn't a solution as apps need for example the shell and filesystem to store setting files at first startup.
There are sub permissions which are quite unclear if you can disable them. Plus, after every app update the new nag screens come up and apps might not work anymore. You say Firefox needs ABC. But how to know what each app needs at bare minimum?

You are not blocking everything for ever.
The template is set to block all at first app install so that the app doesn't get access to sensitive information that it doesn't need. You can deny the sub permissions if you want but this can effect how the app behaves. You don't need to mess with the sub permissions.
At every app update Xprivacy will re apply the permissions that you've already set for that app. You don't need to re do it.
As to allowing Shell and system at first start up go back into Xprivacy and allow these permissions/ re launch app.
The ABC for Firefox was an example. Firefox is a web browser so obviously it needs data access. Root Explorer obviously needs Shell, and System and so on.It is easier then you think.
Once you have setup all the permissions for your apps and they are working Xprivacy has a function to save or export your setup. So that if you change ROM all you need to do is import it and it will do the rest.
If you read the link I included all the answers to your questions are there. Google is useful too.

Question With Root Moving app to system app.

I have never created a thread before because I normally can find my answers by browsing. However, in this situation, I come up snake eyes each and every time. If this is the wrong place to post, I apologize. I am trying to move a GPS app to a system app. However, when I try to move it, I get an error that there is not enough space in the system ROM (/system) for this. (There is only 2.73 MB free.) I do not need much as I am only looking to move this one gps spoofing app. I have tried everything I could find to do from uninstalling system apps, etc., but no matter what I do, it stays free space 2.73 MB. Any help is most definitely appreciated as I am at a loss, and this was the only thing I rooted to do. Please help!
Edit: I forgot to say it earlier, but I am not a pro at all this so speak to me as if I were 10 yrs old. Thanks alot!
You can use lucky patcher to rebuild/install fake gps apps as system apps. Copying by hand is not gonna do the trick.
There should be plenty of tutorials out there, just search for something along the lines:
Spoof GPS Pokemon Go Luckypatcher
Beware though, that those tutorials will not have been written with Android 12 in mind; I have not yet meddled with GPS spoofing with my P6 and do not know whether Google has implemented certain mechanisms to prevent spoofing system apps. You might get into a bootloop or even softbrick your device (I'd say rather unlikely, but there's always a certain chance).
Magisk is your friend. Not very complicated. Create a module with a /system/app or priv-app directory.

He said that he is not a pro and needs everything explained like a 10 year old, you're sure that creating a magisk module isn't a tad too much to ask?
There are solutions that only require a couple clicks in a premade app interface, intuitive and easy. Going in and coding a couple lines is not my definition of 10 year old not pro stuff. I mean it's not a big deal breaker, there are plenty of tutorials to go around (topjohnwu even offers templates), but it still requires some knowhow and poses more risk.
I appreciate your help but I have already done all the recommendations. As I said, when I uninstall apps from the system ROM I gain no space. I have been using lucky patcher to move files to system apps but it says there is not enough room. This is why I asked, according to what I read, it should have worked. I don't know if I am doing it wrong , but when I try to move app to a system app, I click on it and choose tools and move to system/app in lucky. Any help to help me with this issue is really appreciated.
Install the attached version of the App Systemizer Magisk module and reboot. Open a terminal (install Termux app from Play Store if you need a terminal app), su [enter], systemize [enter] and follow the instructions.
If you are willing to share the APK, I can make a magisk module to install it as a system app.

At the menu, type 1 and hit enter. It'll bring up a list of all installed apps, with a number next to each one. Type in the number of the app and hit enter. It'll probably throw an error, but the app should still be systemized - I've seen seen errors since Android 11 but it's always worked

Thank you! I got it as a system app but for some reason when I click on the app it doesn't load and freezes. Any ideas are much obliged!

Question My banking application will not allow me to enter that I am using Whatsapp PLUS

Hi.
Today I needed to pay something through my banking application, but the application did not allow me access because it detected malicious software on my phone and it is Whatsapp PLUS, which I have to uninstall in order to enter the banking application.
What should I do now if I use Whatsapp PLUS all the time, but at the same time I need access to my banking application?
How does a banking application detect that I am using an illegal Whatsapp Plus application?
Is there a way around it?
Thanks a lot.
And for info root I have over Magisk.
This might seem trivial, but have you tried revoking the "Get info about installed apps" permission?
Most apps use this to index all your apps and check for so-called "malicious" package names.

What should I do?
Even if I freeze WhatsApp via titanium backup, the bank's application still notifies me that there is malicious software on my device - WhatsApp.
That I should just uninstall it.

go to your banking app's "App Info" page, under permissions, look for "Get info about installed apps" and if it is "Allowed", change it to "Deny"
this is assuming you are on MIUI. I'm sure other ROMs also have a similar permission.

What is the package name of your whatsappPlus app? You should find it in the "App Info" page for the app. Should be something like "com.whatsapp"

There is no such setting about allowing the installation of applications under permissions - allowed / deny

In that case you either modify the app itself - use apk editor to decompile app , edit manifest.xml and remove permissions like "query all packages" from it . Compile the app and run it again. This might work but if app is protected in some way that it detects modification you might get banned from it or worse :/
Other way is to isolate WhatsApp Plus by using tools like virtual xposed - basically a virtual container. You can install WhatsApp in there and it shouldn't cause any issues but I'm not sure you'll be able to receive notifications... ( You can try installing bank app in there instead but I'm not sure how that'll work... Either it will detect root/xposed or the container itself will allow querry all packages to seep through into main os - this depends on whether virtualxposed has declared permission for querying packages or not )
Third option is probably the best one - Uninstall and use web browser to access banking.
maybe whatsapp plus is indeed malicious
use malwarebytes for android to check whether whatsapp plus is malicious or not
