She doesn't understand that most smartphones are capable of calls and navigating menus simultaneously.

So whenever my mother calls in need of help with her smartphone, can be anything from installing a new app to posting on FB.
I have to explain 2-3 steps, then she will hang up, and call again in 5 minutes, where I will then explain the next few steps, and so on.

How she even manages to navigate that much and calling in between, and then struggling with simple task is unimaginable to me..
