ROCK PI 4 - Raspberry Pi 7 inch Touch Display

Hello everybody,

i have a few questions below:

  1. Is there a possibility to change the display brightness of the Image Android7 (DSI 480P)?
  2. As soon as the display is locked, the display stops responding.
  3. When is Android 9 support planned?
  4. Is there a way to automatically hide the status bar?


  1. Not at the moment, we haven’t adapted it.
  2. Is the touch screen unresponsive? Right now we don’t have a power button, so we can’t wake up.
  3. I don’t know for sure, but there will be.
  4. Maybe you can hide it in app.
