What does it mean when the connectivity icons in the status bar go white/gray?
I've been searching google for this and I haven't been able to find a clear answer for this. Some say it's "insecure connection to Google servers", others say it's only blue when it's syncing etc.
The idea is that connecting to two different WiFi routers I get different icons. One shows blue, the other grey. The only difference between them is that the one that shows grey uses a certificate to authenticate, while the blue one uses a password, like any regular router.
So what's up?
Answer
It is the internet state indicator - grey means that your internet connection cannot reach Google's test server, and the blue icon means that you have a strong connection with Google's test server.
If it is grey, you may have issues accessing some internet services on your device, blue should work fine.
This is available on all types of data connections.
