I have a Raspberry pi 4 with 2GB and a touchscreen https://www.elecrow.com/7-inch-1024-600-hdmi-lcd-display-with-touch-screen.html

I installed this android 13 image https://konstakang.com/devices/rpi4/AOSP13/

Added to config.txt

hdmi_force_edid_audio=1
max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=87
hdmi_drive=2
display_rotate=0
hdmi_cvt=1024 600 60 6 0 0 0

Having:

  • dtoverlay=vc4-fkms-v3d:
    • touch screen - stuck on boot with ANDROID letters
    • HDMI monitor - same
  • dtoverlay=vc4-kms-v3d
    • touch screen - black screen
