The hefty number of iPhone 7 users reported a problem concerning the in-call disturbance.

Today we prepared for you some optimal solutions for distorting and hollow sound, and/or bad microphone performance while making a call.

How to improve bad call sound quality on iPhone 7

One small disclaimer before we start. If your iPhone 7 or 7+ variation are having the hardware issue, this steps may help. However, our advice is to contact your Apple Support.

Disable Noise cancellation on iPhone 7

Noise cancellation is a built-in option that helps you by reducing ambient noise while speaking on the phone. Good intention but some of the users found it unsatisfying. To disable it, follow the instructions:

  1. Tap Settings
  2. Select General
  3. Choose Accessibility
  4. At the bottom, you will find Phone Noise Cancellation 
  5. Turn it OFF

Select Data Only in Mobile Data Options

There may be a problem concerning your Mobile Data. Maybe your VoLTE ( Voice over LTE) is the one that makes calls distorted, so try disabling it. To that follow this path:

  1. Tap Settings
  2. Select Mobile Data
  3. Choose Mobile Data Options
  4. Tap Enable LTE
  5. Choose Data Only instead of Voice & Data

Try using the phone without the case

There are some reports that your case can be the issue while speaking on the phone. Because it covers rear microphone, sometimes may cause the distortion.

Remove your case and check your in-call performance without it.

Turn Off the Bluetooth

Interference may also occur because of your headset and phone speaker. To be sure that is not the case, disable Bluetooth:

  1. Go to Settings
  2. Select Bluetooth
  3. Turn Bluetooth OFF.

Try restarting the phone

If the problem is somehow connected to the software, the reset may be of help. To reset your iPhone 7, do the following:

  1. Press and hold Wake and Volume Down buttons
  2. Wait until the Apple logo appears.

Try updating to the latest version of iOS

Keeping your phone updated is a good way to overcame slight software issues, probably even the sound ones. To update your system, follow these instructions.

  1. Make sure your iPhone 7 is connected to a Wi-Fi and charging.
  2. Go to Settings
  3. Choose General
  4. Select Software Update
  5. Tap Download & Install

  1. go to Options>Cellular>Cellular Data Options>Enable LTE……. make sure it’s on Data ,not on Voice Data. It fixed my problem

  2. I’m on my 2nd replacement – so 3rd iPhone 7 in 6 months & every one of them has terrible sound issues. Callers constantly say my voice breaks up, or is garbled, or muffled, or like I’m talking through water. This is my business phone and I deal with a lot of clients so it is a real issue and no one seems to have an answer. Apple has to be aware of the problem but doesn’t seem to have a fix. Very frustrating.

  3. Believe it or not. My husband bought an iPhone 7 plus two months ago it was a disaster as every one said they can’t understand because the sound is hollow and distorted. He went back to the dealer and got it exchanged but for his bad luck the second was the same. Yesterday he went back to get the third one and it was the worst. I could barely understand him when he called me from work. He is so disappointed and upset. Every single phone should be tested for defects before releasing such garbage into the market.

  4. I second that the phone cases might have been the issue that affects the call quality. It happened to be my experience that every time I was on the call, the other end would tell me that they couldn’t hear me, or my sound was muffed, while I could hear them just fine. I have been using wallet cases for over a year…and ever since I remove my phone from the case, everyone, I repeat, EVERYONE, on the phone told me they could hear me very clearly. My wallet case only slightly covers half of the two microphones my iPhone 7 has…I even made a cut out from my case to make sure it doesn’t cover it, but oh well.

    I still use a case for my phone, but I now make sure none of the microphones is covered. Seems to work so far.

  5. I have purchase iphone7 on 25th September 2017 , I find very poor call sound quality (with incoming & outgoing calls). The shop vendor from whome I purchase did some calling options & said he don’t find any problem which I m experiencing with calls. I feel so bad. I feel so embrace saying I m talking from iphone7 which has bad sound quality. Kindly help.

  6. If I purchase a 1000$ Smart phone I expect that it is in perfect working condition.The apple developers had time enough to test the device before release.The best way to loose costumers.

  7. Literally have had the same issue and told I am shit out of luck.There has to be some way to get a refund or something done about the issue. This is absolutely ridiculous

  8. I’ve had a number of iphones–the 7 is without a doubt the worst regarding sound quality and connectivity. I rarely get through a call without loss of the call or distortion so great the call is a burden. Awful, awful, awful.

    • We hear you, Jim. It seems that they chased flashy improvements while neglecting fundamental phone features.

      • But I can’t believe they can sell you a phone for £850 that doesn’t make calls properly and your stuck with it!!!! In this case you should be given a full refund as it’s unfit for use

        • I have the same issues for 5 weeks. I even got a new iPhone 7 and then today a new sim card put in. It improved for one call and I am back to needing to use the speaker feature to speak with anyone. I asked for any other phone today that I could talk to people on. Verizon said any other iPhone would have the software problem too. Left me hanging…
