If you are using an anonymous account then bind your account to an email address. That way if you have to unintall you can log in with your email address and not lose your progress. E-mail address, or Google Play account, or iPhone-type account, Facebook account, etc. Any of the identifier things that exist "outside" of your physical device.

The original MSM game is very tightly tied to the game servers; every change you make in your game is immediately stored on the server, and will be restored if you have to uninstall and reinstall, or log in from a different device. (You can have the game installed on multiple devices, and access "your own" game from any of them.)  That's why the game instantly locks up as soon as you lose internet contact.

The DoF game is less tightly tied to the servers, and some progress can be lost if you lose net contact or don't shut the game down properly. This has been getting better, gradually... or at least that's my impression.
