Problems with rotating the screen on edge1 android

Edge Android
1

Hello. Installed the Android firmware offered by khadas
I use khadas captain and TS050 screen. The problem is that when rotate the screen, the following happens:

  1. The touchscreen adjusts to rotation and the sensor works in vertical mode.
  2. The screen still displays the interface horizontally and stretches the image, as if it considers the horizontal screen to be vertical.

However, when connected to a monitor via HDMI, the screen flips and scales correctly.

What’s the problem?

Hi @technicalMi ，
Because the TS050 screen is physically vertical, the screen display has been stretched.
What is the firmware version number you are currently using?

I tried to use different firmware offered by the official Khadas website in the section “/products/edge1/firmware/android/”.
I also installed the firmware, which was assembled according to the instructions on the same official website.
But in each case the firmware with Android 10.

@technicalMi Please follow the steps below to first pull the build.prop file through adb, remove persist.sys.app.rotation=force_1and, then push this file in, and finally restart the machine.

C:\Users\25348>adb root && adb remount
adbd is already running as root
remount succeeded
C:\Users\25348>adb pull vendor/build.prop

remove persist.sys.app.rotation=force_1and in the build.prop file.
adding persist.demo.hdmirotates=true attribute in the build.prop file

I followed your advice. I followed each step and successfully changed build.prop and rebooted the device. However, this is not quite what I need. The screen really stopped scaling, but the touchpad switches to a different screen orientation.

Tell me, is it possible to make the screen orientation exclusively vertical? That is, so that the interface is only in vertical mode, and so that the sensor also works in vertical mode?

@technicalMi Sorry, I missed a setting at that time: adding persist.demo.hdmirotates=true attribute in the build.prop file again.

Thank you! Now everything works correctly!

Tell me, is it possible to specify the vertical screen orientation by default in the source firmware files before assembling? This is necessary so that every time after reflashing the device you don’t have to change build.prop via adb.

@technicalMi The firmware we release defaults to landscape display. How many machines do you have to brush?

I can’t say for sure, but there could be many. In addition, we often reinstall the firmware on one device. It’s not too difficult to rewrite build.prop every time, but I would like to set vertical orientation as the default orientation for the firmware. Is it possible to do this?

@technicalMi We can make the startup default vertical screen through the configuration file, but the touch is not accurate. So it is necessary to modify the touch driver code to achieve it. Please contact the business department.
