Q: How to avoid loosing my settings?

A: To avoid loosing your settings follow these steps:

Android OS: backup /NeutronMP folder with all its contents to the safe location. /NeutronMP is not affected by uninstallation.
iOS: backup /NeutronMP folder which is located inside the /Documents folder. To access /Documents folder use iTunes for PC -> select iOS device -> Apps -> File Sharing -> Neutron -> drag and drop to PC the /NeutronMP folder.
BlackBerry OS: close Neutron's process -> create folder NeutronMP inside the /misc folder (you will get /misc/NeutronMP) -> start Neutron -> Neutron will copy its current setting files to /misc/NeutronMP folder and will use settings located in /misc/NeutronMP.
