Hi yes, I get that, more recently in particular. It's getting to the stage where it's uncomfortable to use the phone. And it's not limited to any one finger. I've tried a few touch phones but they all seem to have an effect so far. I suspect it's the electric field and some people being more sensitive to that than others (without wanting to sound too new age!). In damp environments it's not so noticeable (or after having a shower). It is worse in dry air conditions. The effect is less on an ipad for whatever reason than a nexus 7. And is noticeable on an iphone and android phones, even with the haptic feedback turned off- to the point where I use a stylus now when I can reasonably do so. Some screen covers seem to reduce the effect a bit- the zagg ones especially. Also the otter box defender which covers the screen also makes a difference. I'm seriously thinking about going back to using a blackberry with a keyboard! I thought I was the only person but I met someone else who's also having the same experience. The iphone 5 seems better than the 4s. Not sure if the aluminum casing makes a difference.
