Do you have trouble with your FaceTime calls dropping or freezing? If FaceTime randomly hangs up for you, this is most likely due to an unreliable internet connection on your end or the recipient's end. If you like to use FaceTime for long periods of time--like when you're using the app to virtually hang out with someone overnight--call fails could also mean your device is overheating. Here's why FaceTime keeps hanging up and how to troubleshoot it.
Why Does FaceTime End By Itself?
FaceTime can automatically hang up if you have an unstable internet connection. If you're using FaceTime for hours at a time, your iPhone or iPad could overheat and hang up FaceTime calls.
