My speaker starts making rattleing sound at some nodes while Playing music in YouTube or any app.I simply destroys the effect of music. Is anyone facing same issue ...

Factory reset your phone and see it it fixes the issue. If it doesn't, then call our support to get it repaired. I know it's not fun to reset your phone but it will get reset either way when you send it for repair so it won't be for nothing. Plus, you can always make a backup first.
