Collision detection failure with high dpi/ppi phone devices.

I have a game very similar to knife hit, game works fine in normal devices and collision between two knifes detected properly.
Whereas, in the high dpi/ppi phone devices, the collision isn’t detecting and directly hits the target though visually it looks like it overlaps with other knife.

How to overcome this issue of collision detection issue in high dpi devices ?

Thank You So much.
