Update 2/2025:
Starting with Core App version 2.8.1, Tizen 7 can change orientation in a same way as previous generations. Team crafted custom API to overcome Tizen limitation.
Notice 3/2024:
Beware of issues with display orientation on Tizen 7 (QHC, QMC, QBC). On Tizen 7 the system orientation can no longer be changed programmatically as the display has a built-in gyroscope.
To have the content in the right orientation, please keep the orientation in OSD menu in "Auto" mode and ensure the display hangs on the wall in a proper way.
