I have a mobile phone Huawei P20 pro.
I tried to install different versions of iGo Nextgen (iGO 9.18.27.xxx) .
The installation runs without issues.
If I start the program after installation I get a short message on the screen only:
"navigation wird geladen" (In English : Navigation is starting)
This message is for 1 second visible then the program ends.

What I checked in the file sys.txt file :
[rawdisplay]
screen_xy="auto"

data_folder_name="iGO"

remark: Huawei P20 pro has resolution of 1080 x 2240 Pixel


Can someone help me ?
Thank you

merci pour ce job
