On the top of the Galaxy S3 has a LED notification followed by couple of sensors and a front-facing camera. LED notification? Yes, I like it! Galaxy S3 LED notification easy me to know the status of my my phone whether I receive email, miss call, Gmail, low battery and more. Without press the power button (wake-up s3 screen from sleep) and enter password, i can get all of these status by simply looking at the LED notification light color and flashing frequency. We know that you can enable this LED notification by go and set at settings>LED indicator. Here, we can enable the LED Light up when device is connected to charger, battery is low, when you has missed call, messages or any application events.
Yes, it sound good. But this S3 LED notification default system setting not allow you to set the LED notification color and flashing frequency. If your galaxy has been rooted (Link tutorial how to root Galaxy S3), then you can go to the system file and manually set the LED notification . But if you don’t want root your galaxy s3, then you can the application- Light Manager to set the LED notification and flashing frequency on your Galaxy S3. Light Manager allows you to take control of your notification LED colors and the flashing Frequency. I have tested this free application, Light Manager on my Galaxy S3, it works perfectly. I love it so much and hope you enjoy it!
