I have to switch phones and wondered where the save data is located so I can transfer it to my new phone.

Anyone know?

I would hope it would be on the SD card like your Contacts and such are.

Some phones don't have SD cards, in fact most newer ones are moving away from the practice so carriers can charge more for a 64GB version of a phone...

But I digress. I was more looking for a directory location.

For when this thread is inevitably indexed by google's crawlers I found the files in my phone under

Android/Data/com.gamesas.falloutshelter

Vault1.sav

Vault2.sav

Vault3.sav

Are all there and should be copied to the new device to the same directory.
