Installation of apk in android phone problem


So I sent my game, which is nowhere close to completion, to my android phone for testing. When it finally got there, if I open it, the “Your Splash Screen Here” screen flashes between it and a black screen for a seemingly random amount of time, then the app crashes. Any ideas?

Same here.i build game for all versions(x64 x86 arm64 armv7)just able to install only one armv7 in my all three devices and it only run in redmi note 4.and also if i build new project for android it works fine but my project apk is crashing in 2 devices.
Worked in redmi note 4 not in asus zenfone 5…
Any idea??
