[Tizen Application-dev] Touch events in Tizen

It's highly unlikely the Z1 hardware is the problem here. Every modern
touch kernel driver I've seen will support at least 10 input points.
The problem as I recall it (it's been a few years since I've touched
the input stack in Tizen), is that touch input is translated to mouse
events, before getting passed up through the web api. That is, indeed,
limited to just a few simultaneous touch points.

There is support up to X / Wayland, but in or above that layer, they
could be getting translated to mouse events.

Best regards,
