I had updated to Kodi 17 RC4 which was just released in late January. I am running latest Android 7 firmware (2.0.1).
So far it has worked very well for what I want: quality playback from attached USB drive, internal drive and multiple NAS drives on network.
The new interface is fresh and the default skin quite good.
It removes the duplicated drive names of Kodi 16.1 and they show up with correct names now
I note the official release of Kodi 17 is now on PlayStore from 1st Feb. Suggest full back-up of Kodi 16 folder so it can be restored if needed.
I have an extensive Kodi library and it all smoothly updated for me.
The wrapper is still working fine for me, so all 1080p full remux of blu-ray videos and 7.1 audio passthrough are working perfectly.
I still use the "0" stop key patch as I got used to it
Happy to recommend members here try it out for themselves.
