Smartphones have become indispensable tools in our daily lives, and yet, most users only scratch the surface of what their devices can do. Beyond the obvious apps and settings, both iOS and Android devices come packed with hidden features designed to enhance productivity, privacy, and convenience. Many of these features are built directly into the operating system but remain underutilized simply because they are tucked away in menus most users rarely explore. The Samsung Galaxy, for example, offers the Secure Folder, which acts as a private vault for sensitive files, apps, and photos. This feature ensures that even if someone else gains temporary access to your phone, your most personal data remains secure behind an extra layer of authentication.

Users can lock this folder using a PIN, password, or biometric login such as fingerprint or iris scan. Despite its practicality, many Galaxy owners are unaware of its existence, missing out on a simple yet highly effective way to protect personal information. Beyond privacy, smartphones offer numerous tools that streamline everyday tasks. iPhones, for instance, have an accessibility feature called Back Tap that allows users to perform specific actions by tapping the back of their device.
