Well, I don't have a big problem like that on my phone, but
sometimes the touchscreen coordinates seem to be off a bit.
That is, if I use for example the matchbox onscreen keyboard and tap
a key multiple times, maybe 1 in 10 taps or so is recognized 1-2
millimeters off (usually below where I touched).
And if I start numptyphysics and just shortly touch the same spot
again and again, I sometimes get little 1-2mm strokes instead of
just a dot.
