There have been a couple instances when my son calls me and asks if I called him. I didn't, and when I check my phone log there is no indication that I called him yet his phone, an iPhone, says I called. He maintains that only happens from me and occurs when I have my phone in my pocket and accidentally call. I'm not convinced and if that is the case then it must be a bug in the MAXX that only registers a call if you terminate under these conditions. Help settle this; please.
