Volume controller change

Can't you add or remove sound, are the buttons stuck or don't respond to pressing at all? Often it's a worn internal flex cable that transmits pressure. We will quickly replace the module so that you have full control over the volume of your device again.

The service includes

• Diagnostics of mechanical damage versus electronic error.
• Replacement of the side flex cable controlling the volume buttons.
• Test of tactile response and smooth sound level control.
