The script below actually syncs between a plugged in Android phone and BlueStacks, an Android emulator used for gaming, but it could just as easily do two different phones.
The script is very specific to a specific game, I’m just posting it because other people might find it useful, especially in the era where you can’t touch any of these files on the phone itself so you can just use DropSync or whatever.
The script is intended to be run on Windows using Git Bash (https://about.gitlab.com/blog/git-command-line-on-windows-with-git-bash/).
