1. Use a third-party app: There are several third-party apps available on the Google Play Store that can help you hide other apps on your phone. One such app is called "App Hider," which allows you to hide apps like Telegram and keep them password-protected.
2. Use the built-in app hiding feature: Some phone manufacturers, such as Samsung, have built-in app hiding features that allow you to hide apps from your home screen and app drawer. You can check if your phone has a similar feature by going to the Settings app and searching for "App Hider" or "Hide Apps."
