Hi,
I have Mekede A7870 unit with the latest Official DuduOS release 3.6E (or v250905), and there is a bug regarding Day / Night switching.
In the settings in “Display & Theme” -> “Day & Night switching mode” I have the “Sunrise and Sunset” which is based upon GPS.
I describe here the problem, and there is a video to see how it exactly happens.
The headunit has GPS signal, which is visible from the correct time (it is synchronized with the satellites), and Google maps is showing my correct position. The Dudu Launcher according the time uses correctly the night theme, but Google maps stays in day theme. If you go to Android settings, and check the “Dark theme” it show that it not enabled and the whole Android settings menu also uses the “Day theme”.
If you force the “Dudu Launcher Pro” app to stop the problem gets solved. Google maps switches also correctly to “Night theme”, and if I check the Android settings the menu uses also the “Night theme” and the “Dark theme” shows enabled.
I think the problem is related to what I described in another post, regarding GPS not detected correctly.
