Hahaha, I don't have issues finding its home, I can't find the button on the side of the pen.
I like being able to copy text that isn't selectable normally but with the SPen if you hold the button and hover over the text, if a cursor appears you can select that text and do copy and paste. Most of the time you can long press on text but for times when you cannot this usually works if the text is text and not a photo of some kind or if the site or doc blocks normal copy and paste. You also have to use the button on the pen for some air gestures, which I don't use too much but would likely use more if I didn't struggle to find the button. With the lighter color in photos the button seems to be more visible. The black pen has a black button and the shadow around the button that might offer a clue to which side of the pen the button is on as well as it's location on the pen, half way up, closer to the bottom, like that, makes it difficult in dim or low light to find. IDK about you but I do a lot of stuff in the evenings, sitting in front of the TV with the lights out. So struggling to find the button just makes it a pain.
On a side note I use several Good Lock features including Pentastic. My S-Pen says, What can I do for you?, when I pull it out and, I'm home, when I put it away. I tried a custom icon too but they all get in the way when trying to write. Why make the default icons off to the side like a normal cursor but make the custom ones dead center? It covers your text as you write. SMH.
