A number of people have run into a bug with the notification LED on the Moto G. Their notification light won’t ever turn on, regardless of incoming texts, emails, and calls. As best we can tell, this is caused by restoring settings from a Google account, which could include an instruction from an older phone where the LED was disabled, or nonexistent.
FIX:
- Motorola released a widget called Notification Light Widget.
- Stick it on your home screen, use it to enable the LED,
- and then you can get rid of it.
