Kodi’s decision to not support Android versions older than 5.0 for their Kodi 17 Krypton build is highly frustrating. Especially if you have a perfectly useable Android TV box sitting waiting to be used.
There is nothing quite as frustrating as an app that won’t start. Or it goes to a black screen, particularly when it’s a popular app like Kodi. Fortunately, fixing Kodi is fairly straight forward, however, it may mean losing the add-ons you’ve installed and starting again from scratch.
