I doubt it is the Network's fault that I have been experiencing calls terminating. Rather, the design of the Phone App.
The Phone App could use some redesgining. For instance, when every you recieve calls, you need to SWIPE to pick up the call. Why not SWIPE when hanging up? It is important to remember, the Droid's screen is quite sensitive. I have a feeling that because of that senstivity, my face causes my phone to hang up.
Quicker access to the phone app would be much desired for the Motorola Droid. But to which hardware button should better access to the phone be assigned to? I suppose this should be something the people at Motorola should think about in the future. Perhaps they were a little too excited when they worked on the Droid, they forgot to make it a priority.
