We have a Rock 5B which will be running a specialized app on a small touch screen which will be in portrait orientation. I can’t get the display to rotate to portrait even after setting the auto rotate to off and using
adb shell settings put system user_rotation 1
I’ve tried with 0, 1, 2, and 3, but nothing. Unplugging and plugging back in the HDMI doesn’t fix it, nor does a reboot. I tried the other suggestions in this link but they didn’t work either: https://stackoverflow.com/questions/25864385/changing-android-device-orientation-with-adb
I am using the latest Android image Rock5B-Android12-rkr12-20230315-gpt from here: https://github.com/radxa/manifests/releases
OK while writing this up, I decided to test on the previous Rock5B-Android12-rkr12-Tablet-20221129-gpt image, and using the above adb command DOES work. So something is broken in the most recent 20230315 release.
This is a problem because I am currently working on a custom Android image I built by modifying a few parameters in the Radxa Android source code, and I must be using the most up to date code because my custom image has the same rotation issue.
So does anyone know:
A) How I could check out the code for the 20221129 release and make my custom image from that point
B) How I could fix this by fixing/modifying the source code
C) Or how I could fix it some other way?
