I recently noticed that the wi-fi icon on my new Nexus 7 appears in orange for 2 seconds, after being connected to a network and then becomes white again. It is not a problem, since it connects without any problems, however it seems curious to me why this happens? Any idea? This happens ever since I bought the tablet. It runs on Android 4.4 (KitKat). Turning airplane mode on/off didn't change anything. Should I worry about anything in the future? Thank you.
