I’m trying to work out what the different color glowing lights mean on the front of my Nexus 5, any ideas? I couldn’t find a list anywhere on the Android site.
You mean the notification LED lights? Whilst researching this previously it turns out that apps can use the LED light to shine in different ways in different colours. So there is no standard answer, it depends what apps you have installed.
Typically apps will use a colour associated with their icon, so Facebook glows blue, gmail glows white etc.
