iPhone 7 Speaker Grayed Out And Microphone Not Working Solution

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.).

How to Temporary Fix

unfortunately there is no way to solve that issue, a workaround to it would be to use a bluetooth enabled headset to make calls. Keep in mind, if your phone does decide to turn off (such as battery dying on you), the only way to turn it back on would be to follow these steps to get your iPhone 7 past the apple logo:

1. Turn off the device, if the phone is currently on and you can’t turn it off, you can force shut it off by holding the volume down and the power button together until it shuts off.
2. Turn on your phone by pressing the power button, let go once its on.
3. Hold and put a lot of pressure with your fingers at the location shown in the image below.
4. Keep holding until phone turns on and then you can let go.
