My iPhone is making random calls. What should I do?

A lot of iPhone owners reported that their phones have a pretty peculiar issue: the device dials a number on its own repeatedly or even making random calls, using numbers in the address book, while in a pocket or without anything touching it.

As mentioned in our previous guides, no operating system is perfect and iOS is no exception. Still, like in most cases, there are solutions for issues like the phone dropping calls or similar. Fortunately for you, this one is no exception.

If your iPhone is making random calls, you can try following some of the tips in our guide and see if the problem persists after applying them.

How to stop an iPhone from making random calls

Apparently, this issue is predominantly present among iPhone 7 users, but 6S and 5S users are also affected, according to some users. Specifically, users report the phone app, besides making calls on its own, often freezes and requires a hard close

However, a discussion on an Apple board revealed that there are actually four solutions to this issue. Therefore, if – no matter the model – your iPhone is making random calls, try following the steps below and see how it goes.

Solution 1: Reset the Settings

First thing first, a simple reset can actually be the easiest to apply the solution. Go to Settings > General > Reset and tap Reset all the settings. After this, observe how your phone acts throughout one or more days.

Solution 2: Turn off voice control

Even though this feature was designed to help users, it can cause problems as well. One of the reasons why your iPhone is making random calls is that you’re accidentally asking it to do this, by using the Voice control mode. Turn it off and get rid of the problem once and for all.

Go to Settings > General > Passcode Lock > Turn Passcode Off. This will deactivate the feature and stop the random calls.

Solution 3: Put the phone into DFU mode

Apparently, this is a method which a lot of users reported to be working. Follow these steps in order to apply it:

  • Plug your phone into your Mac or PC and make sure iTunes is running
  • Turn off the phone
  • Press and hold down the Power button for three seconds
  • Press and hold down the Volume Down button while still holding the Power button
  • Keep holding both buttons down for 10 seconds. If the Apple logo appears, it means that you pressed them for too long and need to start again
  • Let go of the Power button, but keep holding the Volume Down button for 5 seconds. Again, if you see the ‘Plug into iTunes’ screen, it means that you pressed them for too long and need to start again
  • If the phone’s screen remains black, your iPhone is now in DFU mode

After putting the phone into DFU, wait until iTunes detects it as in recovery and prompts you to restore. Pick this option and wait until the process is over. After this, set up the device as new.

Solution 4: Update to the latest iOS version

Finally, let’s not forget about Apple’s past and how some new iOS versions do more damage than improve the phone’s functionality. Therefore, you need to update to the latest one, in order to fix the problem and stop your iPhone from making random calls.

Connect your phone to a PC and launch iTunes. Shortly after, you will see the update option. Choose it and select Software Update in order to get the latest iOS version, which will fix the problem.

  • Get an Android. No issues along this line. However, a long time ago, I had somehow dialed 911. The phone was still in its case. So on the phone rang and I picked it up, it was emergency services asking me police fire or medical. I insisted I did not make the call. Then I found out you can dial 112 and it’s the same as dialing 911. But I wouldn’t try the 112 thing unless there’s an actual emergency. I never got an answer to why 112 worked. I guess it’s because those two numbers are right next to each other, whereas 9 is a long diagonal from 1. Well, that was in the age of early cell phones, so hopefully things have improved.

  • My s7 has a mild and inconsistent flicker. sometimes there is a gray “film” over the screen, but I can still see and use the phone with no problems. If all this means my phone is going to die, I need to replace it (I have ordered A51). BUT if the flicker does NOT mean the phone is dying, I have other things to spend $$ on.

    Can anyone tell me if the flicker means the phone is on its way out?? I can keep or SEND BACK the replacement I might have ordered too soon…

    Thanks so much.

  • turning off the passcode is a security issue, what kind of site would suggest this?

  • Hello my iPhone 8+ in midnight time make call to my hubby phone while we are sleeping. It,s happens two time but hv space like 26 mnt how can be like that??

  • I got a strange sudden call from 200-69 it didn’t give me the option to continue or hang up, it was an automated system say the phone number didn’t work.

  • Useless directions tell you to use non-existent menu items. Specifically, there is no such menu item “Passcode Lock” on my 6S, nor anything else resembling that.

  • First; there is no passcode lock on my Iphone 7 Settings>General>Passcode, so frustrating when someone says this an d there is no such with these directions, was there a step missing, or do they now call it another name?

    I strongly do not recommend solution 3 without backing up all of your information, as IPhone Supports says to go to default and what you are saying here sounds like it. Why not warn the readers they will lose everything?

    • Hi Sarah, my iPhone 7 has Settings>Touch ID and Passcode. You will be required to enter your Passcode before you can Turn Passcode Off. I have just tried it. Let’s see if it works because the auto dialing of numbers is such a bother to me .

  • My Iphone 5C makes calls to people all hours of the night and day, including long distance and international calls. Nothing, not even the above steps helps. It also sends messages, pictures, lights up and takes random pictures. MAKE IT STOP

    • 5c’s were/are notorious for “false touch” issues with the displays. If your phone often taps and opens things you are not tapping when the phone is in use, it is defective, and the phone itself will need replaced. Replacing the display only will not fix the issue.
