All I get is TouchScreen. Multi-Touch is never there.
https://www.gsmarena.com/samsung_galaxy_j3_(2017)-8438.php did finaly write multi-touch but TWO fingers is multitouch!
Others complain about it too. https://forum.xda-developers.com/galaxy-j3-2016/help/fingers-multitouch-samsung-j3-t3630535
My bet is nope, just 2 finger support.
I have a game that i would like to play with 4 fingers but my phone can only detect 2 of my fingers when i add a third my screen just kinda locks.
It's a Samsung J3 (2016)
