What is the explanation offered by manufacturers and vendors for why this is the case?
Have there been legal challenges to this practice?
For instance, I can’t remove the apps ‘Facebook’ (not OS-related), ‘Analytics’ and some non-essential apps by the phone’s manufacturer.
Using the network protocol feature of the NetGuard firewall I can see that very frequently data is (attempted to) being sent via these apps. I have not investigated the content of the data being sent but maybe somebody else will do so for common system-apps and phone models until new Android alternatives exist.
Furthermore, is there a way to disable such apps in a way that has similar results on phone performance, security and privacy as uninstalling them (like sandboxing the app) without rooting the device and using default Android OS on the hardware?
