Koying released the Alpha version of SPMC 17 (Krypton) . You can install it alongside with Kodi and/or SPMC Jarvis.
https://github.com/koying/SPMC/issues/936
Tested it on firmware 1.1.09 (Android 5.1) and it works fine. Still prefer SPMC Jarvis, but maybe it solves some problems with Krypton and Android 7 (or Android 5.1)
