Firstly,
@Joeeye, there is no way to set Apps as the default, which would be my personal preference, so I get Games again each time I use the Galaxy Store app. Secondly, AFAIK, some apps are only available through the Galaxy Store and have to be updated through the Galaxy Store so using Google Play Store exclusively is not an option.
I have had to uninstall (restore to factory default version) several Samsung pre-installed apps, disable auto-update on them then disable the apps themselves but many unwanted pre-installed Samsung apps, even obsolete desupported ones, cannot be uninstalled. I have to do this for all of mine and my family's devices and any new devices that we acquire which is very frustrating for apps that shouldn't be factory installed in ROM in the first place.
I think that it is most unprofessional and biased of Samsung to assume that all of its smartphone and tablet customers are primarily interested in games, including their business customers, when I would imagine that this is far from being the case.
