I ran across this :
" How do I upgrade from v17 to v18?
Main page: Installing
ANDROID USERS: Don't uninstall an earlier version of Kodi/XBMC before installing the new version. Uninstalling first would remove all of your settings. Just install the new version and it will replace the older version and retain your settings.
In most cases you can just install Kodi v18 over Kodi v17. All your settings and library are saved and will continue to work in the new version. See Installing for specific install instructions.
Most basic (video, audio, etc) add-ons that worked in Kodi v17 should still work in v18.
If you have any issues (settings not being copied over, blank screens, etc) when updating from versions older than v14: remove the new version, install the older version of Kodi/XBMC from
Code:

, and then upgrade to the next version. In other words, if you have v14, first install v15 and run Kodi, Quit Kodi and then install v16 and run Kodi. Quit Kodi again and install v17, then run Kodi. Quit Kodi again and install v18, then run Kodi."...!
In case anyone is Interested in what to Load Kodi 18.0 on...!
