Apparently to use SuperSU currently working Android version is Nougat - yesterday I’ve buit an image for VIM1 - with GApps and SuperSU - all works (I have SuperSU Pro licence - all got updated fine).
As for VIM3 Pro, I tried it with TS050 touch screen - it did not work at all with Android Pie built from source. Also audio is not passed via HDMI. I also plugged in Tone Board, but it was not giving sound either.
Currently I have Ubuntu Bionic Xfce built and burned to VIM3 Pro - there both HDMI audio and Tone Board works fine. After @numbqq updated Kernel also TS050 touch screen works with Ubuntu.
So to sum up, Android Pie on VIM3 Pro:
- Touch screen TS050 doesn’t work;
- There is no audio via HDMI and via Tone Board;
- SuperSU is not installed when using ˋhttps://github.com/khadas/supersuˋ;
- There are no controls to enable/disable top status bar and bottom bar;
- I couldn’t find how to reach typical Android settings - only right menu opens. In Nougat you can select More settings and see full list of usual Android settings.
