Why is there a cracking noice during calls?
Hi, I replaced my friends screen and battery on her iPhone 6s. The phone was heavily damaged on the screen and had been in for repair before in a studio. So of course there were 2 loose screws in the phone and two that were bearely attached. Anyway, she got her phone back and during calls she says she hears a crackling/sparkling noice, both on loudspeaker and normal calls. But its fine when using headphones. It also makes crackling noice when playing music on the speaker. Anyone knows what could be causing this? I wouldent think that both speakers could have broke at the same time so I dont know if replacing these would help.
Sorry if my english is bad it is not my native tounge.
Any suggestions would be appriciated.
Is this a good question?
