@DUDU-Meng Hi... sorry for my late feedback. I drive my car every day so i test a lot, like new beta but i have not really time to write my feedback here.
My last version intalled is the version provided in DUDU 3.8 Beta. It is Carlink V260920.
No bug for me on my 2000x1200 screen.
FHD resolution is perfect but it seems that scale is a little too low.
For example, to have elements bigger on my dual PiP main screen, i choose 280 DPI. Because at 200 DPI, elements like in Waze is too small.
And on Android Auto / Carlink, DPI seems like 200 or 180 and above all, it seems that DPI is fixed in Carlink and not sensible to change done in Dudu setting.
Here the differences between V260.205 (1st pic) and last version V260920 (2nd pic)
