volume buttons and sound on/off not working.
I replaced my moms iPhone 4 screen and now the volume buttons and silent on/off button stopped working.
I thought maybe it was the headphone jack and volume control cable but the headphone jack is still working.
Could the cable still be bad even though the headphone jack is still working?
I have already tried to restore and hard reset it. so it must be a hardware problem.
Let me know which part it is i would need to order.
Thank you so much for you help :-)
Is dit een goede vraag?
