Why does holding with a finger get cancelled when i tap with another finger?

[Android Central Question]

I have a samsung a10 that it's screen and magazine was broken a while ago, and after i fixed it, whenever i hold or drag something with my finger, it goes back when i tap with another finger, is it because the magazine/screen wasn't original? (the one i put was 500 bucks and the original was 750 bucks.) I also tried restarting my phone a while and did not work.

Welcome to Android Central! Test the multitouch capability using an app like MultiTouch Tester. If it only allow registers one touch at a time, then something's wrong with the digitizer (or you got a digitizer that doesn't support multitouch).

You did the installation?
500 is kinda expensive for screen and digitizer
