Can I turn off Google Play services?
The only solutions are: Disable Google Play Services (and suffer the consequences) Remove updates to the application (Settings > Applications > All > Google Play Services > Uninstall updates). You might need to head to Settings > Security > Device Administrators and disable Android Device Manager first.
