I have had a Galaxy Grand New for about 3 weeks now. Bought after about six months of loneliness and misery, to replace my lost Galaxy S4. Looks like it does more than the S4, but superlatives are no bedfellows of this fine device.
Apart from phone specifics not Handled by Android, there is so much in common between Android phones, especially if the same make, like Android. I don't even know how to set things up nicely for switching windows, copy&pasting etc, and I'm sure so many other cool tricks my phone can do that still amaze me.
Now I'm asking, what guidance is canon for being a touch-screen master over such a simple thing as a Galaxy Grand.
