If you are considering buying a Samsung Galaxy A3 (2017), you might also want to know if this model has a so-called Notification LED installed. This is a LED light on the front of the smartphone, mostly to the left of the earpiece. Via such an LED the user can be informed about different new notifications.
The answer to the question of whether the Samsung Galaxy A3 (2017) has such an LED is unfortunately "No".
Instead Samsung has integrated an Always On Display to the Samsung Galaxy A3 (2017). New notifications are also displayed to the user. The only drawback here is that the Always On Display needs more battery power than it is the case with a simple LED light.
You now know that the Samsung Galaxy A3 (2017) has no notification LED.
