It is very important, to keep the KODI setup running smooth, that you clear temporary files from the devices every once in a while. Clearing the Cache will help resolve many performance issues with KODI.
In order to Clear cache from the Amazon Fire TV device you have to go to the Settings of your device. Device Settings can be accessed by pressing the HOME button of your remote. To learn more about the Amazon Fire TV Box / Amazon Fire Stick, please check this post.
While on the HOME menu, Click Settings. Then Click Applications – Manage Installed Applications – KODI. You will have a screen like the picture to the right. When on this screen click Clear Cache. Remember: Never hit Clear data as that will remove all KODI setup.
