My L730 switched off automatically when I hearing songs or using any chat apps. I didn't run any high end apps in BG. But it happened. What is the cause

How long have you had the phone and has the phone been normal ever since?

Well my 830 used to do the same thing. I couldn't figure out what the issue was but a simple rom reflash fixed it. I also have all my applications installed on the phone memory and not on the microSD card

past one month and it happened 5 to 6 times recently. hard resetted one time

If the ROM trick doesn't work then you'll have to bring the phone back to the store and ask for another one (If your warranty still covers it). Otherwise you will have to live with the fact that you have a faulty device.

Mine recently died as well after displaying this exact pattern.... But I had my phone for a year
