Never hand your phone to someone without using this hidden security trick

Need to let someone use your phone for a moment — whether it’s a friend or a stranger — without letting them poke around? Maybe you want to show a photo, an email, or a funny TikTok, but nothing beyond that. Android has a built-in feature for exactly this called App Pinning, and it’s easy to use. It locks the phone to a single app, preventing access to the home screen, notifications, or other apps until you authenticate. iPhone has a similar feature too, and I’ll show you how to use both.
