★★☆☆☆ M O · 5 Oct 2026 · v10.58-c956ec4it came installed on my Samsung Galaxy Tab S11 but closes immediately on opening, told me to clear cache, check for updates n reinstall but still closes when trying to order, it's says it has a bug n to wait for developer to fix..That is the crash message...There is a Bug & wait for the Developer to fix,,,this was the crash screen,,,,There is a Bug & wait for the Developer to fixDeveloper reply · 5 Oct 2026Sorry F-Secure Mobile Security is closing immediately on your Samsung Galaxy Tab S11. Since you’ve already cleared the cache, checked for updates, and reinstalled it, and Android reports a bug requiring a developer fix, this may need further investigation. Please send us a screenshot of the crash message so we can investigate further.
