DUDU-Meng ok now that you mentioned CarLink app.
I found this newer CarLink app version on the forum v2.25.1020.0906 that doesn't not have the resolution issue at all. The carplay screen on resolution is fine all the time. However, it introduces new issue the CarLink app DOES NOT react to steering wheel previous, next and play/pause button after the device wakes up from standby mode.
The older CarLink version v2.25.0926.1708 that came preinstalled with DuduOS 3.7 beta v251104 has the screen resolution issue but does NOT have steering wheel previous, next and play/pause button issue after device wakes up from standby mode
So the resolution issue is from CarLink 2.0 app and not DuduOS itself.
Issue # 2. The door information displaying repeatedly from my other post, i will test that with the firmware you provided and give feedback
