I bought a Z30 on ebay used. and I got it today, and I upgraded to 10.3 hybrid. When im calling on the earspeaker, the sound is really staticy and not very clear but the voice is hearable. Any help?
Was it like that before the update? If not, then probably best to go back and either load the OS again or go to an official one. There's not a whole lot that can be done really.
