JhonnyD As I wrote earlier, the GPStest application is related to the launcher, so the package would have to be completely removed from the system, uninstalling via ADB without root does not help, because the package still exists in the system and you still can't install GPStest from the Google Play Store. The only way is for the devs to fix it in the system itself, apparently the preinstalled version is not the same as the one from the Google Play Store, or modified for system use, it's hard for me to say. Howeber, i have no idea, whether in the case of root, removing the application and installing it from the GP Store will ensure the correct operation of the Dudu launcher. Maybe someone has tried and could comment on this issue? @DUDU-Meng @dudu-lai maybe know something?
