Guess you are right - my hands are too small. But since they won't grow anymore I have to look for small devices if I want to use them with one Hand only. N9 was perfect. Jolla 1 is just a tad too big (for me)

Back on Topic: I also try to arrange those apps I need the most next to the right border (I am right-handed) The problem are the four apps in the first row. It is wonderful that I can use them easily if no other app is running. However, when there already is an app running, using any of the first row apps is awkward (for me, with small hands) because it is hard to reach to the top row while trying to hold the phone securely with one hand.
