iPhone 7 Plus: Callers can't hear me

I found a solution for my iPhone 7. The OtterBox I was using on my iPhone 6 was blocking the rear microphone, a small black dot next to the camera, in the top left corner. It doesn't appear to be covering it, but it appears to be just enough to block it. I filed the OtterBox down just a bit in that area and it works just fine.

I have just received yet another replacement 7 Plus and once again people are struggling to hear me. That's with 2 different networks. Phone is not in a case, have tried noise cancelling on & off. Now, I also have an Honor 9 and a Galaxy S7 here and the same sims in those phones have no problem with call quality whatsoever. In the UK and I have tried a 3 sim and a Sky Mobile sim. It must be an issue with the hardware.

Looks like it was the clear plastic cover on top of the screen. Is there one that fits perfectly out there?

I'm on t-mobile, iPhone i7 plus, brand new. Here's what finally worked for me...ALL of the following. Now it works.

1. In Settings, make sure WIFI is turned ON

2. In Settings, turn OFF Noise Cancelling

3. In Settings, Set Enable LTE to Data Only

4. Hold top of phone near ear/head…angle voice receiver/bottom of phone away from face somewhat; don’t press phone like a slab against your head.

5. Speak firmly and kind of loud…but not abnormally loud. Don’t mumble.

I'm having this problem with an iPhone 6.

Try this as a test: find the back microphone (which is right next to the camera bump). Place a call, and try talking with a finger covering the back microphone, and without. I'm finding that with the back mic covered up, voice calls are crystal clear. With the finger not covering the back microphone, it's muffled.

Although this seems like a problem with noise cancellation, turning that feature on or off didn't help.

My earlier post wasn't quite correct. The soft inner shell of the OtterBox didn't stop the rear microphone picking up my voice, but the outer shell did. Even filing it down didn't help.

The solution was to buy an OtterBox for the iPhone 7 to replace the one I had for the IPhone 6. There's just enough difference to make a difference!

Do you have cases on these phones? What kind? Have you tried calls without the case? Are you all using the same cell provider?

I recently had a Genius Bar appointment regarding this issue. I took with me 3 different network sims, all uk, 3, O2 and EE. The assistant allowed me to call him from outside the store so he could hear what I was trying to explain. He admitted with all 3 sims my voice was only clear when holding the phone horizontally to my mouth. Now the problem is my phone passed all diagnostics so they just blame the networks. I left the store without a replacement and am now thinking of an alternative.

I ended up calling tech support with the 7plus and laughed a little when he needed me to keep repeating myself. They told me when I get my phone today to not update it to 11. Don't waste your time with them. Get transfered to customer relations. They have the ability to give you a different model. If this one doesn't work I'm suppose to get an 8. I'll keep you updated.

Check out your LTE in settings. What I had to do was make sure it was set to data only and everyone can hear me well now

Had my phone over a month and it's the same started of ok now afew weeks old and I cannot even ring anyone cos they cannot hear me and I'm sick of repeating hello can you hear me everytime I make a call, I use my phone for work and its resorted to me borrowing a colleagues phone to make calls!

Again, try the troubleshooting steps in the support document I provided, and as a last resort, make a Genius Bar appointment at the nearest Apple Store, or you can use the Contact Support link at the top right of these pages and set up a mail-in service if necessary.

Try to update iOS to 11.0 version

I've tried it with and without the case - in different states even. My workaround is to use headphones (with the adapter provided with the 7). The sound is crystal clear that route. But I certainly can't carry headphones around everywhere just to make a call. It actually seems like it's happening more and more lately (nearly EVERY call).
