I'll be honest, I've never experienced this but I would like to help by giving some ideas and a bit of information.

First of all, have you tried restarting your phone, or manually stopping the application in your mobile tasks? Your device might be lacking in memory (RAM) therefore it forcefully closes your SIF application. Closing unwanted applications might help your case.

Regarding your love gems, you won't lose your love gems as long as you don't transfer accounts from iOs to Android or vice versa.

Also, do you have your passcode? Before uninstalling, back-up your SIF files in your computer if using android or save it on your iCloud if using iOs.
