Smae peobleme for my galaxy A70, i did some tests, when i'm gone to safe mode the probleme disapear, also when i enable the pointer tracing in developper mode it shows correctly and constantly the place where i touch by more than finger, also it works fine with some multitouch test apps, so the conclusion is that the problem does not came from the hardware, it has a software probleme, wich has to be resolved by samsung, i did contact samsung assistante and they said that's normale that your phone stop recognizing your fingers when you put more than one on the screen, but why this issue does not exist on my other samsung phones. Please make us a solution because this issue is so disapointing people especialy when playing games like pubg.
