IPHONE 7 SPEAKER GREYED OUT AND NO SOUND ON CALLS
The iPhone 7 and the 7 Plus has a common issue in which your phone will have the speaker grayed out when you're making outgoing calls. Other symptomps of this issue is that your microphone doesn't work, trying to record a video will result in no sound in the video. This is usually caused by the iPhone 7 dropping, there isn't necessarily a need for a physical damage on the phone, the fact that it dropped will cause this problem to occur.
The iPhone 7 speaker grayed out is usually caused by a chip on the iPhone 7 logic board, this chip is called the Audio IC Chip. There is a slight chance that it may be a software issue (which will require you to factory reset your phone simply to just “test” and see if it is), but based on our experience, this is definitely a hardware issue on your logic board. When your phone constantly drops and or gets hot this audio ic chip becomes loose and therefore causes your microphone not to work and your speaker getting rayed out when you make calls. This audio IC chip is soldered on the logic board (a logicboard is the same as a motherboard, it’s what controls everything on the phone.).
