On previous phones I've had, whether they ios based, Android or Windows Phone, the screen illuminates when an email or Whatsapp/SMS message is delivered.
With my N5 I hear the phone vibrate on the desk but it doesn't light up for me to have a quick glance to see if it's worth picking up and reading.
Is this normal with 4.4 or have I overlooked something in settings?
This is normal with Android.
