Swiping is too sensitive about direction

When I swipe down to close an application or to lock the screen I've noticed that the gesture is very sensitive on direction. Unless you make the swipe only very close to orthogonal to the screen border it is not accepted as a "close" swipe. Instead it's regarded as a downward drag movement and only the pulley menu is activated, the content is scrolled or, if the home screen is active, move to the lock screen, even though the movement comes from outside of the screen.

Edit: Since there seems to be a problem with reproducibility I wanted to find out why it happened to me on a regular basis. It seems to be dependent on the straightness of the movement more than direction. Using my index finger I do a fairly straight swipe and then I can do that almost diagonally and my Jolla still regards it as a close swipe, but if I use my thumb (which I do most of the times) the movement is more like a small arc and even if I start perpendicular to the screen border it still isn't handled as a close swipe most of the times.

Edit2: Did a small video showing the issue. http://youtu.be/5-4SDLcK0_M

As reported by @lomo in https://together.jolla.com/question/13256/fine-tune-swipe-gesture-for-pulley-menu/ it seems that a side swipe has the same issue. Changing heading to reflect that.

I've started to see this again on my Xperia X since the SfOS 3 upgrade. Not only slight deviation from orthogonal, but also straight down swipes. Feels like a poll frequency issue or similar.

Haven't experienced anything like that.. Just tried those swipes and I can make them nearly horizontally but making sure I start from the outside of the screen and they always get recognized correctly.

@jjaone: I did some more tests and added extended description to when it might happen.

I use the swipe down very often to lock my screen, never experienced anything like you describe. Usually use my thumb for this too. Now I tried to reproduce and it was really hard not to make it a swipe down. Even when I swiped in a zigzag motion it was still registered as swipe down.

I can easily reproduce this on my device. In my case the critical angle is something like 30 degrees of vertical. When swiping in an 45 degree angle I can only get the pulley even when starting the motion far outside the screen.
I do not think the shape has much to do with it. Perfectly straight motion (along an ruler) also produces this.

I can also reproduce this.

Based on my experiments, the critical thing for a motion to be recognized as a swipe (from outside of the screen) is that your finger crosses the screen edge in a single, smooth motion. If there are multiple crossings, or if the finger jumps at the crossing, the motion is registered as a pull (from within the screen). If the motion is smooth, it can be nearly horizontal, and still get recognized correctly. It is slightly more difficult to accomplish a smooth motion with the thumb of the same hand that holds the phone than with a finger of the free hand.

changed push/"swipe" to terms used in the User Guide: Gestures - swipes, pulls, taps and flicks

please watch the video and tell if that's not a smooth motion.

This is clearly not the reason on my device, I can reproduce it with very smooth motion. I wonder if the reason is more on the hardware side as many people seem to have trouble reproducing the issue.

My experience is that it only takes some lightness of contact: fast motion with dry skin (like mine) does it very often. I can pretty repeatably either swipe or pull with the thumb motion shown in the video; it only depends on if I start at the speaker or closer to the edge.

and thanks @phle for correcting the terms.
