Using Fingertips on the Touch Screen

[Tri3Dent]

Hey Androidforums mates,

Just got a question for you guys. When I use my fingertips (index finger) on the touch screen (not my fingernail but just below it), it's not as responsive as using the flat part of your finger. Does this happen to you? Every time I use my fingertip to scroll around, it would always accidently open an app or accidently open up a link. If i use my thumb by the flat surface, it's fine as well.

Example:

The fingertip I was talking about is labelled "A" which I am having problems scrolling around with (seems like not sensing that part of the finger sometimes). If i use the part labelled "B", it's fine and 'connects' with my finger. It's fine when I press harder using "A" but that's cuz it is sensing more of my finger.

Is it same as you guys?

I personally use my thumb but I see what you mean, this has been the case for me for all my touchscreen phones, not sure why though, maybe the way they are made?

Its because Capacitive touch-screens use a layer of capacitive material to hold an electrical charge, touching the screen changes the amount of charge at a specific point of contact but using the tip of your finger is a smaller surface area and the screen does'nt detect it compared to using a larger flatter part of your finger which makes for a better electrical connection.
