Build and Run mobile game doesnt work like editor!

Hi guys,

I have a little problem, when I ‘play’ my mobile game in editor its all ok, but when I try build and run, just on my phone start a logo of unity and then only 1 sec and game is shutting down…

P.S
The assets in editor are okay, but when I build the assets they reduce…

Please help me guys! :frowning:

Okay closing is now ok!

The assets still reduce when I build apk, so what can I do?
