Hi Fedi. I have a question about @GrapheneOS
Some acquaintance of mine tried to install GrapheneOS on Pixel 8a and encountered a weird problem.
Apps doesn't have internet on WiFi if you do not enable "nearby devices" access for them.
Some apps like GrapheneOS store doesn't have this setting so no internet on WiFi at all.
What can ever be a reason and how can it get fixed?

@yura Android apps with no reason to access local network addresses should not add it as a requested permission.
It works the same way on the stock Pixel OS and other up-to-date Android devices. Most Android devices lack current standard privacy and security patches/protections. Comparing GrapheneOS to out-of-date Android forks by OEMs is the wrong way to compare the behavior. Comparison should be against an up-to-date Android 17 OS. 17 QPR1 and 17 QPR2 are Pixel OS exclusive for now though.
@yura There's no difference between GrapheneOS and standard Android 17 when it comes to this. Nearby Devices is not required for internet access. Apps targeting Android 17 or later require Nearby Devices for local network access. They don't require it to use the internet via Wi-Fi. It sounds like the network may be tampering with DNS results and trying to redirect traffic in a way that's visible through using local addresses. It wouldn't impact internet access on a normal network at all.
