I tried other brands and models and the cursor is visible. (Ex. Huawei Y6 )
I hope we find a solution.
Yep. I contacted Samsung support but got the "well, we don't support graphics tablets" speech, so brick wall there. Emailed Huion and they asked me to check my OTG and pointer settings and to contact Samsung support. I just replied that I did those things and that others were having the same problem so we'll see if we get any progress on that. In the meantime we'll just have to wait until someone decides to code something up for us muggles.
Speaking of code, and I'm no expert so grain of salt and all that, I've got a few theroies:
Option 1: Force cursor visibility always
The cursor DOES pop up when a mouse is plugged in, therefore by changing some variables, we should be able to force the cursor to always be on (root likely required). I know that the phone tracks pointer location when you hover the pen over the tablet because, when plugging in both a mouse and the tablet to the phone, one can see the cursor moving. Unfortunately, the cursor only appears when the mouse is wiggled and disappears once the pen moves the cursor (so basically we get a cursor that flashes in and out really fast). On top of that, we can't click and drag while the cursor is doing the flashy thing.
Option 2: Edit device recognition
This, I imagine, would be a lot more work, but it would offer a nice quality of life feature. If we could get the phone to recognize the tablet as a connected mouse, the cursor should appear when we plug it in and disappear when disconnected. I'm not sure, however, that drawing tablets send the same type of data as mice do so the phone may not be able to interpret it regardless.
Option 3: An overlay app that tracks pointer location
While this would need to be made from scratch, I think it the most straightforward approach. An apk that puts a symbol over wherever the pointer location rests! Just enable it to draw over other apps and voila, instant cursor. This would require that the phone monitor cursor data without the stock cursor being on, though.
But yeah, until either something gets coded up, Samsung gives us an update, or Huion gets their stuff together, we're kinda stuck. If you're dead set on using the tablet regardless, the best I've been able to do is mark off the boundaries of "phone mode" with a pencil on the tablet, put a dot in the center, download a "crosshair" overlay app, and position the crosshair so that it lines up with the drawn dot on the tablet. Then you should have a point of reference for where you're about to tap! Scuffed? Absolutely. Functional? You bet.
