Alcatel OneTouch 6040X not showing Camera as installed Application

Question

i got a strange behaviour of my Alcatel which runs on Android 4.2.2.

Neither with

List<ApplicationInfo> myAppList = getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA);

nor with

List<PackageInfo> myAppList = getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA);

do i get my Camera App. It's simply not showing up in the list. On a second device, which is a HTC, the Camera with the same code is inside the list.

Does someone have experience with this behaviour or does someone know a workaround or a suggestion.

Update

I also started a new question with new infos but again it doesn't look promising.

The most important thing is that i get Camera-App as ApplicationInfo.

Would appreciate that.
