Your code is a bit odd:
#1 You want to get a touch position but query the mouse position.
#2 And you query the mouse (!) position not at the time of touch but later.
#3 You ignore the index property of the event. This may lead to “misunderstandings”.
Android devices can actually have mouse devices attached but i doubt that this is your intent. Touch event may also trigger mouse events if the touch->mouse emulation is set on in the project settings (and vice versa) but this is unnecessary here.
If you don’t want to completely process the event in the _input handler then you should at least save event.position for later use in a Vector2 variable. In _input this position is the viewport position of the touch (not the local position inside the control where _input is triggered).
If you ignore event.index then the touch_hold variable may have a wrong value at times if the user touches with multiple fingers. I.e. press with index=1 for finger 1, then 2nd press with index=2 for another finger, when finger 1 is now released then touch_input would be set to false even though finger 2 is still pressed. But this may not be a problem for your app.
With my code I want to know if the player is touching his phone at any time and be able to get his finger position for some calculation, even when dragging his fingers.
As for the index I only need the first touch thus ignoring the event.index.
I used the get_mouse_position() on the _process because if I don’t know how to find the touch position, a similar func that get the touch position doesn’t seem to exist to my knowledge ( get_touch_position() )

It is not a question of preference, but mainly what worked to a degree, when I try to save event.position at _input() for some reason I get nothing.

When you say android devices can have mouse device you are talking about physical device, is this intent to mouse->touch ?
what I understood is you can call the mouse position on your code and it will be equivalent to touch position.
If you drag across the screen the event InputEventScreenDrag will be triggered (multiple times). It also has a position attribute to query the drag position but no pressed attribute.
Saving the touch position should work somewhat this way: (untested)
var touch_pos = Vector2()
var touch_hold = false
func _input(event):
if event is InputEventScreenTouch:
if event.pressed:
touch_hold = true
touch_pos = event.position
state=1
else:
touch_hold = false
elif event is InputEventScreenDrag:
touch_pos = event.position
func _process(delta):
if touch_hold:
x = touch_pos.x
y = touch_pos.y
#and so on...
If this still does not work then you could put some print statements in the touch pressed/!pressed handling. Perhaps this will show what is happening while debugging.

Thank you so much !!!
touch_pos = event.position was the key I didn’t know that we can do this (again I’m beginner but I probably need to re-read the documentation with a different set of mind ) I though event.position work only with the mouse thus my odd code.
Mouse and input coordinates
