Hey Warlord,
The next thing I’d recommend is looking in the project directory for Saved\StagedBuilds\Android_ETC1[package name]\Content\Paks for a pak file. This is the result of the cook and packaging.
There is a utility call UnrealPak.exe in the Engine/Binaries/Win64 directory. Extract the contents of the pak file using this tool:
unrealpak [full path to pak file] -Extract [full path destination directory]
This is everything included in the OBB so you can see if there is content that shouldn’t be included and what size they cooked to.
