Anybody with an Android device (usually it doesn’t matter which OS and/or ROM you are running) has encountered the situation, when status bar icons (e.g. WIFI and/or GSM/UMTS) are either blue or gray/white. On a sidenote: whether it’s gray or white depends on the OS and the color settings, so from here on I will just write using the word “gray”.
Throughout the internet you can find various answers to the question why icons are either blue or gray. The short explanation is this:
- BLUE: the device is “connected” to Google services
- GRAY: the device is NOT connected to Google services
So what’s the long answer then, and what does it mean to be connected to Google services?
