LED Illumination not working

[PhoenixMani]

Hello

I have got my Xperia in Feb 2014. My experience with the phone was quite good. Recently all of a sudden the LED doesn't light up when its supposed to. Sometimes while charging it will never light up but after a few restarts it will and later it won't again. I have tried the service tests and even there it'll work whenever it wants to. But only when i use the Music app it works absolutely fine. All of my light settings are on, I have downloaded the "Illumination Bar", and I'm not using stamina mode.

I am on stock 4.3, updated to the latest firmware last year, and i haven't installed any new apps.

Thank You.
