Can I block background processes from using mobile data or Wi-Fi on Android?
Background processes often consume data without your awareness, leading to privacy risks and unnecessary data usage. Android doesn’t have a native solution to block background processes and services. But don't worry.
Fyrypt is an iptables-based firewall which - in addition to being an app firewall - lets you block background processes from accessing mobile data or Wi-Fi. Using Fyrypt you can block apps and processes based on their UIDs as well as PIDs. Plus it offers many other features to control and monitor the network activity on your device.
Alright. It's been configured. But how do I know it's working? Fyrypt also shows you what's being blocked. See How do I monitor which apps are connecting to the internet on my Android device?.
