A hidden menu accessible via a secret number
On TikTok, the "#SamsungHacks" hashtag counts over 3.4 million views. Under this keyword, several viral videos unveil hacks on Android phones. While composing a special number in the phone call application, a hidden menu appears automatically. To do so, type in *#0*#. This code will redirect you to a page that displays several programs to test your smartphone's screen or speakers. Buttons called "Red," "Blue," "Green," allow you to display the selected color on your entire screen while the "Speaker" button allows you to test its output simultaneously, though not while listening to music. Some users warn that you should not overuse it since it may create a bug.
A fun but pointless hack
This hack doesn't serve any purpose but is fun. Go to "Settings" then tap "About phone " and "Software information." You then need to tap several times on "Android version" for your phone to display a black layout under Android.
Transform your phone in a negative version
If you want a distinct display, Android phones can reverse colors just like the negative of a photo. To do so, go to "Settings" then tap "Accessibility" then "Visibility enhancements." By activating “negative colors,” your entire phone will be affected, even your applications.
