Crash game - ios big scene.

Hi , I've just launched my game for app store in beta test (test flight ) . So i tested on different "hardware" , and work great for iphone x , xs ,xr , but I get crash when I loading big scene/gameplay (the project has 3 scenes : menu (small scene just ui) , dealership (small scene) , and big map ) on iphone 6,7,8,se2 . I think I get crash because of RAM . Also I tested on android device (with 2GB ram) and same results(crash) . Do I need to split big scene in small scenes and load dinamically ?

 

Yeah , if anyone have this kind of error , splitting the big scene in small scenes is going to fix problem most likely , and also try to not use direct references , instead you can use Resources , or even better Addresables https://docs.unity3d.com/Packages/com.unity.addressables@0.4/manual/index.html
