Feature Request: Built-in App Lock for One UI

Dear Samsung Team,

I am a Galaxy S24 Ultra user and I would like to request a built-in App Lock feature in One UI.

Many users need to protect apps like WhatsApp, Messages, Gallery, Photos, Email, and other personal apps even when the phone is already unlocked. For example, if I hand over my unlocked phone to someone, they can easily open my messages, OTPs, photos, or personal apps.

Secure Folder is a great feature, but it is not a replacement for App Lock because it creates a separate copy of apps instead of protecting the original ones.

Please add a native App Lock feature with PIN, Password, and Fingerprint authentication, similar to what many other Android brands already provide. This would greatly improve user privacy and security.

Thank you for considering this request.
