Touchpad is too sensitive on BlackBerry PRIV

[v6ak]

Environment:

• BlackBerry PRIV, Android 6.0.1. The phone has a touchpad combined with the physical keyboard.
• OsmAnd+ 2.4.6 for Android
• offline maps

Unlike older BlackBerry phones, the phone runs real Android, not BBOS.

Steps to reproduce:

1. Open the map
2. Slide vertically on the physical keyboard/touchpad.

Expected behavior:

a. OsmAnd moves the map vertically. (Preferred.)
b. OsmAnd zooms the map decently.
c. OsmAnd ignores the touch. (Even this would be better than the actual behavior.)

Note that some apps seem to take advantage of some standard Android motion API, so that they handle touchscreen and touchpad by the same code.

Actual behavior:

OsmAnd zooms the map very aggresively even after light vertical movement. The zoom has some “velocity”, so that is scrolls roughly a minute after the finger movement. One can hardly want to do this.

Update: This seems to be too sensitive only when I quickly release the finger (so that it has some momentum). Nevertheless, I consider the momentum effect unwanted for zooming (it might be welcome for scrolling, though), because:

1. While user might want to scroll something massively, user can hardly want to scroll from 1m scale to 500km scale (i.e., 500 000).
2. The current implementation makes the application unresponsive for about a minute (time measured by guess) even on high-end phone.

Same occurs on the BlackBerry KEYone with Android 7.1.1 when trying to use the touch-functionality of the physical keyboard.

On KEYone, it is the same issue, just more annoying, because you can't hide the keyboard and because the keyboard is more at edges. I've found no way to disable this feature in OsmAnd. 😔 And of course, you don't have to worry about touching spacebar on KEYone. I wonder what device it can be useful on. I remember there is some old (2010 or so) Motorola with touchpad, but I am not sure if it behaves this way. I am not even sure if OsmAnd can run on such device. Also, there are laptops (and tablets with docks), but the touchpad also probably works in some other way. If the feature is useful on no device, the best fix would be removing it. It is annoying on PRIV (Android 6), KEYone (Android 7.1.1) and it might be also annoying on Passport (a device with BBOS10 and Android compatibility layer).
