Hidden Smartphone Features You Didn’t Know You Were Missing

One of the most overlooked Samsung Galaxy features is Secure Folder—a private space for sensitive photos, files, and apps. Protected by a PIN, password, or biometrics, it works like a mini safe on your phone. Many users don’t realize it’s already built in, offering an extra layer of protection. Modern smartphones are packed with useful hidden tools that can make everyday use easier without needing extra apps.
