Contact info available in Task
So when you create a Task from within a Lead the contact info needs to be available inside of the Task on the Android/Iphone App so that when you are reviewing your task you can make a call from within the Task list.
Thanks for posting!
In the Android app, you can long-press on a task to see a menu that lets you jump directly to the contact (or deal, or lead).
You can also tap on a task in the iOS app to do the same thing.
I hope this helps!
