I prefer SPMC to Kodi. It is a fork of Kodi that is coded for Android operating systems and runs much faster.
You can get it on the google play store or download the apk here. http://spmc.semperpax.com/
I prefer a vertical menu that can be adjusted to my liking. The MIMIC theme is available from the Kodi repository. Just go to the settings/appearance and click on skin. Then get more. Then choose MIMIC.
