[Q] Is the threshold for registering a touch event adjustable? topic
I'm using an Adonit Jot style stylus on a Android phone (ZTE V5 Max on Android 4.4.4, but I experience similar problems with other devices), which generates less signal on the capacitive touch screen than a finger. The phone's software appears to be configured with only hand touch in mind, and drawing with the stylus results in broken lines a lot.
On the pointer location debug display the minimum pressure I can get for a touch point to register is 0.09, and with this stylus I get 0.10~0.11 most of the time, so the head room is really low. With a finger the pressure level is usually above 0.15. This makes me wonder if I can tweak the threshold for a signal to be registered as touch to make inking with the stylus more stable.
I'm aware of some Build.prop configs suggested here and there. However after playing with several versions and reading some of the documentation I believe those values only change the touch behavior after a touch point has been registered. The actual threshold for a signal to be recognized as touch is not changed, and my problem remains.
Is there anything I can play with to change such a threshold? (I have root access.) Or is it hard-coded in device-specific drivers?
