App installation issues on Galaxy S26 using Smart Switch

If certain apps do not install or transfer to your Galaxy S26 using Smart Switch, you can manually download them from your preferred store (e.g., Galaxy Store, Play Store) or the app's official website. However, if the app still does not install, it may be due to service termination. For further assistance, don't hesitate to contact the app provider directly.
