I've installed a firewall (AFWall+) on my phone, and I've manually whitelisted every app I wanted to allow accessing the Internet, including system apps. So everything is blocked by default, and I add apps to the whitelist as necessary until what I need works and nothing beyond that.
I've just discovered some apps in the whitelist that I never whitelisted myself and don't even remember ever seeing before to be honest. These are:
- "Intent Filter Verification Service"
- "Market Feedback Agent"
- "Print Service Recommendation Service"
- "Google Partner Set Up"
From what I can see, these are from Google, although I'm not clear on what they do (except the Feedback Agent).
How could this happen?
- Device: Samsung Galaxy S5 Duos (SM-G900FD)
- OS: LineageOS 14.1
- Android version: 7.1.2
- The phone is rooted with SuperSU.
