iPhone 7 audio problems - GSM-Forum

timvandenboo · 08-25-2018, 11:42

Got here an iphone 7 with the greyed out speaker button during calls. So this means broken track under audio ic. So removed audio ic with pre heater and repaired track and replaced audio ic.

Had already more than 15 units fixed but this one is doing weird.....

Speaker button isnt greyed out anymore but still no mic or sound during calls. Mic in voice app works fine also speaker works with normal audio outputs..

Does anyone had a suggestion.

HI,

Did you fix this problem. I have one where voice memo works now but no sound in calls. Reballed 3x but still the same.

Also, after trying a call and getting no audio if you go back to voice memo it doesn't now work.

Thanks

I've tried in good housing, still the same. Loud speaker isn't greyed out in calls but there is no sound besides a quick hiss from the top speaker then nothing.

Voice memo works.

Thanks
