Beginners • RPI 4 Model B DSI LCD Display Issue on Android 13

Hello Everyone,

I'm new to Raspberry Pi and facing issues getting DSI LCD displays to work on my Raspberry Pi 4 model B running Android 13. Here are the details:

– Upon booting, the DSI display initially shows the rainbow colour screen, but then turns off and stays off. HDMI works fine.
– Running Debian GNU/Linux 12 (bookworm) on RPi 4.
– Restarted several times, but the DSI display remains inactive.

**Hardware and Configuration Details:**
– Raspberry Pi 4 Model B
– Android OS version (13)
– DSI LCD screen details: [5inch DSI LCD](https://www.waveshare.com/wiki/5inch_DSI_LCD)
– Interface used to connect the rpi to dsi -an FFC cable to connect the 5-inch DSI LCD to the 15-pin DSI interface on the Raspberry Pi board.

**config.txt Settings:**
# Kernel

**Additional Information:**
– When using Raspberry Pi OS, the DSI LCD display works correctly.

I'm new to this, so any suggestions on how to troubleshoot this issue would be greatly appreciated. Thank you!
