How to make a front camera flash for notifications
Notification LEDs at the top of the screen will usually flash when there are incoming notifications whether from phone calls, SMS, WhatsApp, or other notifications.
But unfortunately the light from this notification LED is actually not optimal because the size is too small, especially if the smartphone is in a bright room, this Led notification is almost invisible.
After trying a number of ways, I finally managed to get a solution, which is to make the front camera flash as a notification if there are phone calls, SMS, or incoming WhatsApp chat.
And to do this, I use the front & back flash notification app, for those of you who want to download it please click here: https://goo.gl/dUYa9k
Please see the tutorial video to find out how to use this app to make the front camera flash as a notification.
Thank you
