Hello AdHern,
Thanks for connecting with us. We understand that your iPhone is placing calls without your input. We’ll do our best to sort this out. Let's complete the following steps:
• Restart your iPhone
• Go to Settings > General > About and verify if you have an update available. If so, check out: Update iOS on iPhone
• Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.
• Remove your case or screen protector to see if that helps.
• Clean your iPhone
If you continue to experience the same behavior, please provide us with the following details. Having this information will allow us to have a better understanding of the issue:
• Does this occur while you’re using several apps or one in particular?
• Has you phone suffered from any type of physical damage?
We look forward to hearing back from you with the results!
