Android ROM that can feed fake data to an app when a permission is requested
Is there an Android ROM that has the ability to provide the app with fake camera stream, location, microphone stream, gallery, storage files etc...?
It would be incredibly useful to allow apps to work while giving no info / no access to private informations / permissions.
There was an option for a fake gps app somewhere in settings a while ago, not sure it still exists.
Other than that, I doubt it. Android is incredibly locked down. Maybe if you root your phone and install magisk there is a module? But then you risk losing banking apps, netflix etc.
Edit: Spoofing GPS seems to still be possible. Download a GPS spoofing app, enable developer options, then in there search for "Select mock location app"
I think XprivacyLua (an LSPosed module, which LSPosed is a Magisk module) can be used to interfere with sensitive permissions, but recently the developer announced the end of its maintenance. I still use it though.
Can also confirm that it works, at least for GPS spoofing.
Does it still work with android 12/13?
Don't know about 13, but I'm using it on 12 without issues. I mostly just block things though, so I've not tested spoofing data.
You can look into shelter app on fdroid that uses work profile to isolate any installed app in that profile form your contacts or sms or any data.
Perhaps /e/OS might be something to look into. Supports wide amount of devices and has a built in tracker blocker, location / Ip spoofer. Been liking it on my Oneplus 6t
