I downloaded and copied the entire "iGO_Luna" folder from this post to the phone's memory (rooted Galaxy Note 4 Exynos, Android 6.0.1, res.2560 x 1440). After iGO Luna is installed, the program starts. There is a choice of language, I choose the PL language and the application closes unexpectedly. I restart iGO Luna. This time, only the start screen appears and the program closes again. I have maps, buildings, Poi on the external card. I do not know what the problem is, because the program does not show any error with resolution, missing global_cfg file etc. Maybe I need to change an entry in sys.txt? The problem with starting iGO_Luna is with every skin (Aldo, Garigor, Pongo, VAG, Wal24)
