Led Music Effect is a free Android app developed by LVP under the category of Utilities & Tools. It is an application that blinks the LED lights of your phone in sync with the music played on your device. The app supports all devices with LED or flash, and you can change the LED color in the song for phones that have one LED RGB, such as Xperia L, Z2, Note 2, etc.

One of the best features of this app is that it runs in the background, so you can play your favorite music on any music player and still enjoy the LED blinking effect. Led Music Effect also allows you to blink LED with three different colors, each led as SP, P, U.

However, some users might face issues with the app. If the dialogue shows "cannot start visualizer," it means your ROM is missing certain required libraries. In that case, try playing with Google music or PowerAmp. Also, if the application crashes, please send logcat or report through Google Play. Lastly, it is recommended to use a supported music player per the above description and contact the developer by email if your player is not supported yet.

Overall, Led Music Effect is a fun and unique app that adds an extra layer of entertainment to your music listening experience.
