Android smartphones like the Samsung Galaxy S1 do not have an LED notification light to indicate when a text message or phone call was received by the device. If you’re used to looking for a notification light but no longer have one on your newer phone, there is a solution. Thankfully, there is an app called NoLED that provides a great solution.
Simply Download and install NoLED from the Android Market and you will be prompted to configure the app for your Hangouts, Messaging, Email and Call notifications and add the widget to your screen. The app will then light up a pixel on the screen when a notification is triggered.
