Hi all. I have an iPhone XS in my shop, that i’m experincing issues with. There is no sound in the bottom speaker, no matter what i do, it seems. I have replaced the charging conn. flex, along with the speaker itself - i’ve done this a couple of times on the phone to exclude faulty sparepart. I’ve also done a complete reset to exclude software (no recovered data) - and i’m starting to accept the fact that it may be mainboard-related. Has anyone come across a situation like this on XS? Is it perhaps audio-IC like on iphone 7, or something else? Thanks in advance :D
Hello Mikkel. As you suspect, this is most likely logic board related. The problem could be the audio IC although I suspect it has more to do with the interposer layer between the two boards. This can happen following drops or over time through repeated micro-flexing. In a sense, the same root cause for the iPhone 7 Audio IC issue but a totally different result on the sandwich-like design of the X series.
