How to make your phone camera flash light when receiving calls, messages, or notifications
Method 1:How to Check and set your phone’s notification LED light
To enable the feature, you should first check if it isn’t already built into your Android phone’s software. For Samsung owners, it should be under Settings > My Device > Accessibility > Flash Notification. On recent LG phones it may be found under Settings > Accessibility > Hearing > Flash Alerts. Regardless of your phone’s make and model, the accessibility settings menu is where you should look first. If the option is not available there, you can make its camera LED flash when calls are incoming using an app made for the purpose.
So here is how to configure Call Flash. After downloading it from the Play Store by CLICKING HERE, you must launch the app and go through the “First Time Settings” menu. The reason for this is to let the app figure out how to access your camera’s LED. Don’t worry, the process is painless and has to be performed only once. Now tap on “Test Flash” and see if it lights up. If it does, then move on to the next step. If it doesn’t, choose an alternative method from the drop-down menu and try again until the LED blinks.
This method works on all android e.g TECNO, GIONEE, Samsung (most of samsung android has this feature it advisable to use METHOD 1) .
