How to change the display Orientation in Android 10 hdmi port

[subash_p]

Hi,

I am working on an i.MX8MP custom board with Android 10_2.3.0. I am trying to change the display orientation from landscape to portrait in my Android image, so I added the following changes in my .mk files.

$ settings put system user_rotation 3 command in android 15 means gives me the correct_portrait_view

However, this command does not work on Android 11.

I will attach an image showing the orientation I am expecting in Android 10

Hi,

surfaceflinger rotation information will not pass to HWC in Android10, please try the attachment in HAL and use 'settings put system accelerometer_rotation 0/1' for test.

Hi @Zhiming_Liu 

After applying your patch, I can see some changes on my screen, but the resolution is not good. Also, when I connect a mouse, it works in the way of landscape navigation, not in portrait navigation. 

And also, the navigation bar is not visible.
