Metamask - where is wallet file stored on Android/Samsung devices?

My friend did not backup his 12 word seed. He then uninstalled metamask. He now has re-installed it and has lost access to his wallet I am trying to help him and wondering where the wallet file for Metamask is stored on Android. Hoping we can find this in file manager and then import to newly installed metamask in order to regain access to his coins. He remembers his metamask password so would be able to decrypt the wallet file.

Any advice would be genuinely appreciated. Please help!
