How do I do screen shots?

Screen shots are done by pressing the power and the home button simultaneously for roughly one second. Then the screen corners will flash a white border, with acamera snapshotsound and a notification will pop up.
In the second image is the result that appears in the pull down notifications panel. This is accessed by simply swiping from the top of the screen to the bottom.

How do you switch between apps?

If you hold the home button for roughly two seconds, when released the screen should switch to have the currently open apps,as in the image.
Click on the app to open it up or to close it by swiping it right off the screen.

Starting up the device

After placing the micro sim and battery into the device, I connected the power cable provided and the device turned on. Got the fuzzy feeling of excitement mixed with anticipation.
Start with setting the time and timezone. The initial steps are pretty straight forward as seen below.
The thing I was very impressed with, is the additional 50gb of Dropbox space.

Exciting start

As always getting new tech or gadgets is a very blissful event. This case for me it was the Samsung galaxy s4! Pre-ordered through Vodafone on Saturday and arrived on Monday. Very happy!
