Tinker Board Forum

i have a Tinker board S with a
Raspberry Pi 7" Touch Screen LCD in a
Raspberry Pi Touchscreen Case
I have installed android Version 14.4.0.5

i need to flip the screen 180 because of how the case is designed

when i go to setting/display/HDMI/HDMI rotation/ 180
the screen dose the flip animation and doesn't flip but the touch screen flip and it make it very hard to undo.

any idea on how to flip the screen
the screen is connected to the MIPI DSI connector
and pins 3-6 on the gpio

I tried the build prop method last year with a older android version and had the same affects.

Hi warwolfx0,

Since you are using android..
have you tried to install Apps like..
Rotation Control... APK here...

Hope it helps,
k,

yup i have tried that same app and have the same issues.

i figured it out
so it turns out i was missing a command in the
build.prop
this is stock
ro.sf.hwrotation=0
sys.hwc.device.primary=HDMI-A
sys.hwc.device.extend=DSI

i was just doing the ro.sf.hwrotation
once i did the device.primary to DSI the screen works.


ro.sf.hwrotation=180
sys.hwc.device.primary=DSI
sys.hwc.device.extend=HDMI-A

also the app works now.
