What information applications without permissions can see on my phone?
I already know that apps can communicate with each other with mutual consent, but what else?
For example Obtanium knows versions of installed apps (so it can prompt to update them) and 1Password showed me push notification "Google play services are disabled, enable them...". So Apps know what other apps you have installed, and even if they are disabled?
What else apps can know or do inside the same profile on my phone?
