Wrong Collision on emulators instead of real device

Hi, let me explain better, my English sux sorry.
When I build the game all feel good, all colliders are in his place.
But when someone try to record a video playing on an emulator, some invisibles walls appears or throwing an item to the floor could disappears.
Should I review something in my physics before to do a build?

Hi!
Unity doesn’t officially support emulators.

Yes, I understand, but let me search if someone have this issue any time and got a fix, I want to learn why this is happening.

Testing in some devices with less memory, I have found some bugs than never appears under Unity Editor, could be a problem related with the use of the memory is taking my project really?
