Why External Extensions usually do not compatible with non Samsung devices?

Hi all,

I tried to test several external extensions with Samsung devices, Its works very well. But when I try to test it on non Samsung devices for example: SONY Xperia Z1, It shows error message say “Unfortunately, MyApp has stopped”, And my app closes.

I also tried to use Export an App By QR code. Not a Live test Companion.

Is this happen with anyone? Or anyone know why this error message appears?
