I was frustrated to see my wife to use Jolla for the first time. The click accuracy is too tight and she tried to tap with one finger but nothing happened. Then she tried to tap slow and after that she tried harder - still nothing. The problem is that detecting of tap needs the finger to be upright and not askew. The detection area is bigger if the finger is not upright. I have had similar issues with camera app. It's quite hard to make a shot for me, e.g. with thumb, and one of the biggest reasons is the tight accuracy of the tap event area.

Does she have long fingernails? My wife does and she had similar issues.

Not really but touch interface was new. The old phone was s40. Anyhow, I think the touch interface should recognize the tap with finger independently of the angle of the finger and not just graze.

+1 here, this is especially noticeable in the Lock code input screen and in the terminal. Haptics are an issue as well.

From what I've seen with some people new to touchscreens, often the problem is with the touch being made in a rolling fashion (touchpoint grows and shrinks in various directions such that the center is not stable) and interpreted as a drag. That'll be more likely the larger the total contact area

sp3000: I'm particularly talking about the same touch I apply to unlock my N9 - it doesn't always work in the Jolla. You always roll when you touch anyway, the trick is to judge better.
