Interesting correlation, I would not have thought to check that, especially since on tapatalk it does not show the user side panel with their location and such.
Sad to say I have not talked on my phone since that day, although I did miss a call today from my dentist reminding me of my root canal tomorrow... I had a good reason not to answer that one.
If it helps though, my messed up call was incoming and I called the person back without any issues.
