I'm downloading apps from the playstore and after it downloads I see a message that says " no room on homepage" and I'm only given the option to uninstall, not open. The apps also do not show up on the apps menu. When I go into managing apps, ionly then I see them but I still can not open. What am I doing wrong, lol? I do not have an sd card, yet. So, is this why I can't open them?
