a static noise starts when i connect the earphones

[sam2801]

Even when the volume is zero noise just doesn't stop. Is it a software issue or a hardware issue? This problem has started just after I exchanged my phone at the service centre

does it happen when you are in safe mode?

if it does, this means it is more on the hardware problem. try to have your phone checked again at your local service center Local support
