[Reynard Temmerman]

When I download an apk from google or install a game from share it, it sea's app not installed. Why.

If you're downloading an actual APK from someplace, you need to enable 3rd-party app installs.

If you're installing apps from the Google Play Store (the ONLY way you'll get apps "from Google") there is no need to change that setting.
