4.3" Waveshare Touchscreen
So, I have loaded Emteria onto a RP3. If I hook the RP3 up to my computer monitor with HDMI, it works great (no touchscreen of course). If I put the Waveshare on the RP3, I only get a white screen. I have added the contents of the "4.3.img" to the MicroSD card. I have also tried to play around with the "Config.txt" file to set things as required in the Waveshare instructions. I also tried setting the HDMI to safe mode. Then I got a rainbow pattern (instead of white), but it still didn't work. Removing the Waveshare from the RP3 and connecting them with an HDMI cable (separate power for WS and RP3) looks the same. Anyone?

same here with 10.1 inch waveshare.
There are two different things to solve:
1) Set the correct resolution. Here you can refer to other forum posts like https://forum.emteria.com/discussion/99/emteria-android-on-rasppi3-with-makibes-7-1024x600-screen#latest
2) Enable touchscreen support. It depends on the drivers / connection type. Most of USB-connected touchscreens work fine out-of-the-box (unfortunately not all of them). If we find a way to integrate more USB drivers for touchscreens, we will be happy to do so.
