There is no notification light on this phone, you can use the LED flash as one, but you will need to get an app, just search the store for "flash alerts" and such and chose the one that best suits you. play.google.com/store/apps/details?id=com.manzy.flashnotification&hl=en or play.google.com/store/apps/details?id=net.megawave.flashalerts&hl=en
*update, I just learned that there is an option if you didn't want to DL yet another app, It is under settings/my device/accessibility, scroll down to the hearing section and there it is - Flash notification, camera light blinks when you receive a notification. Why this isn't under the ringtones and notifications settings? Your guess is as good as mine.
