Calibration works but ui is bugged, so it took me a while to figure out what to do cause there seems to be some text, but it's white on white and sais no and ok buttons after going through it a few times I got the pen working quite well though which is nice for finding some hardware for a console and still being able to use it outside that

Just got the Sonar Pen today. It doesn't work with Median, but it does work well with ibis Paint. The pen pressure works great. 👍(UPDATE ON REVIEW) The Sonar Pen seems to be working great with Median on my Galaxy A32, but not my Kindle. I draw on my Samsung devices more so overall, the Sonar Pen is great!

When I try to calibrate it, it won't take me to step 2 even though the pen is plugged in

Doesn't recognize the pen. Plugged in via USB-C to 3.5 mm port dongle.

Doesn't work well with median paint, it connected and worked well at first, but after several touch the pressure sensitivity and brushing function doesn't work at all. I don't know whose problem it comes from.
