I tried in every way, nothing to do with Android 7 these are the problems encountered.
1- the MediaCenter App, shared folders are available, but if I try to open them I always get the message
"network error, please check network state".
2- in Kodi are available both the shared folders and their content, but the files are only playable with Kodi Video Player and not with the Wrapper, which gives me the message
"click" OK "when playback has ended".
3- with the ES File Explorer App, you can play files shared with the HiMedia VideoPlayer. Finally this App works.
In conclusion, after a day dedicated to the new firmware, which I really appreciate for its additional functions and the background walpaper, I was forced to downgrade to the custom version 1.1 with my displeasure.
For now, waiting for any solutions I'm stuck to this version.
Greetings
