Smaller package, BloomKernel(32mb) in APK?

Hi all,

I made an Android app on unreal and I am trying to make my apk as small as possible.
The app is very simple, I hardly use textures.

I have already done some things to make my app smaller and I have now got it up to 60mb.
Because I still think 60mb is too big I went to look further and I saw the following.

In: ‘Project\Saved\Cooked\Android_Multi’ I see 2 folders.
One has the name of my project and is 8mb and the other is called ‘Engine’ which is 47mb.
When I looked further into the folders, I saw that 1 file is extremely large.
You can find it in: Project\Saved\Cooked\Android_Multi\Engine\Content\EngineMaterials.
The file is ‘DefaultBloomKernel.uexp’ and is 32mb.

I went to search on google and as far as I see I don’t need this file but I can’t manage to get it out of my apk. In project settings ‘bloom’ is unchecked so why is my APK so big?

I hope someone can help me with this!
