Construct 3 APK not working on my phone

So, in Construct 3, I made a mobile game on my chromebook. I get the apk, on android version 5.1 (my phones version, it can't update its old). When I play it on my phone, there isn't even the C3 loading screen. It's just pure white. It works perfectly on my brothers phone, and I'm not sure if this is relevant, but it is at android V12. I would like to get my games on my phone. Does anyone know why it isn't working (If you need more details, ask)?

It should work, as Construct still supports Android 5.1. It's difficult to say any more without more information. To find out more about what's going wrong you'd need to check for errors in the console (which with an APK will mean setting up USB debugging).
