iPhone randomly calling contacts while in pocket or idle

Please keep the iPhone screen locked when not in use.

1. If Voice Control is turned on, your iPhone may dial a number accidentally if you say a number that is similar to a contact's name. To turn off Voice Control, go to Settings > Accessibility > Voice Control and toggle the switch to the off position.
2. If your iPhone is connected to a car stereo via Bluetooth, the stereo may be programmed to automatically dial the last number that was called on certain conditions. To check this, consult your car stereo's manual.
3. Some cars or car accessories come equipped with motion or proximity sensors that can trigger certain actions, including automatic dialing from the recent call list when your iPhone connects to the car's Bluetooth system. Here's how it might work:
   1. Motion detection: Some cars have motion sensors that detect when the car is in motion. When the sensor detects movement (e.g., when you start driving), it can trigger specific functions or actions in the car's infotainment system, including initiating a call from your iPhone's recent call list.
   2. Proximity detection: Additionally, some cars have proximity sensors that can detect when your iPhone is in close proximity to the car's Bluetooth system. When your iPhone comes within range of the car's Bluetooth signal, the car's system might automatically establish a connection and perform preconfigured actions like redialing the last number.

To disable this feature or adjust its settings, you may need to explore the car's infotainment system settings or consult the car's user manual to find information about controlling automatic dialing or other features related to Bluetooth connections.

It's worth noting that the presence and functionality of these sensors can vary depending on the car's make, model, and year of manufacture. Also, the way they interact with your iPhone and its settings may vary. If you're unsure about how to manage these settings, it's a good idea to check the car's manual or consult with the car manufacturer or dealership for specific guidance.

If the iPhone is dialing from resting on a table, it’s probably a hardware problem.

Ghost touches and missed touches can be a symptom of a display or digitizer problem.

If you are using a protective case or screen-protective film, remove all that, and clean the iPhone, and test again.

If the problems persist, contact Apple Support.

Keep the iPhone screen locked when not in use.

When you're moving around with your iPhone in your hand or in your pocket, the buttons on the side of the phone can be easily pressed, which can accidentally dial a number.

This is especially likely if you have a case on your phone that makes the buttons more sensitive. Use a case with a folio cover: This will help to protect the buttons on your phone and prevent them from being accidentally pressed.

Please keep the iPhone locked when not in use. If you can't do that, then try this...

Go to Settings > Accessibility > Touch, then tap Haptic Touch or 3D & Haptic Touch. Choose the touch duration—Fast or Slow. On an iPhone with 3D Touch, you can also choose the pressure needed—Light, Medium, or Firm. Test the new setting on the image at the bottom of the screen.
