We're resolving this as won't fix for now. Various phones are going to handle both asset bundle data and addressable bundle cache similarly, these issues don't occur in later versions of Android, and eventually as the cache builds and dependencies are created it should level out on all versions. The cache being 8k without addressables means that more data is being read from the phone memory than with addressables and it's cache, this is not necessarily a good thing. If you see the cache continuing to go up after 6 or 7 runs in 1.5.1, and it goes up exponentially filling up the phones storage, we can take another look. But realistically 800k for an app isn't too concerning.
