Android is one of the most popular mobile operating systems in the world, with millions of users accessing it every day. One of the features that makes Android stand out from other mobile operating systems is the ability to customize and personalize the user experience. However, there are certain features and settings that are hidden within the Android operating system, and not readily accessible to the user. In this blog post, we will discuss what content is hidden on Android, why it is hidden, and how to access it.

What is Content hidden on Android?

Hidden Files and Folders

Hidden files and folders are a common feature of computer operating systems, but they are also present on Android devices. These files and folders are typically used by the system or by apps, and are not meant to be accessed by the user. However, there may be times when you need to access these files or folders, either for troubleshooting purposes or to modify certain settings.

To access hidden files and folders on Android, you will need a file manager app that supports this feature. One popular file manager app is ES File Explorer. Once you have installed the app, open it and navigate to the folder where you want to access the hidden files. Then, tap the menu button and select “Show hidden files”. This will make all the hidden files and folders visible in the folder. You can then access and modify these files as needed.

Developer Options

Developer options are another feature that is hidden on Android devices. These options are meant for advanced users and developers who need to test and debug apps or modify system settings. However, accessing these options can be useful for regular users as well, as it allows you to customize the user interface, improve performance, and access additional features that are not available by default.

To access developer options on Android, you will need to enable them first. To do this, go to “Settings” and tap on “About phone” or “About tablet”. Then, scroll down to “Build number” and tap on it 7 times. This will enable developer options on your device. You can then access these options by going to “Settings” and scrolling down to “System” or “System & updates”. Tap on “Developer options” and you will see a list of settings that you can modify. Some of the most useful settings include “USB debugging”, “Animation scale”, “Background process limit”, and “Force GPU rendering”.

System UI Tuner

The System UI Tuner is a hidden feature in Android that allows you to customize the user interface and add or remove certain settings or options. This feature is not available on all Android devices, but if your device supports it, you can access it by following these steps:

  • Swipe down from the top of the screen to open the notification shade.
  • Press and hold the gear icon (settings) for a few seconds.
  • The System UI Tuner will appear in the settings menu.

Once you have enabled the System UI Tuner, you can customize various aspects of the user interface, such as the status bar, quick settings, and notifications. For example, you can add or remove icons from the status bar, change the color of the battery icon, or rearrange the quick settings tiles.

Dialer Codes

Dialer codes are special codes that can be entered into the phone dialer to access hidden settings or features. These codes are often used by developers or advanced users to troubleshoot issues or modify settings that are not available through the normal user interface. Some of the most useful dialer codes for Android include:

  • ##4636##: This code opens the “Phone information” menu, which allows you to view various information about your device, such as battery level, signal strength, and network type. You can also perform diagnostic tests and modify certain settings, such as preferred network type and network selection mode.
  • ##34971539##: This code opens the “Camera information” menu, which allows you to view information about your device’s camera, such as the resolution, sensor size, and ISO levels.
  • ##0##*: This code opens the “LCD test” menu, which allows you to test your device’s display and touch sensitivity.
  • To use a dialer code, open the phone dialer app and enter the code as if you were making a call. The menu or settings associated with the code will then appear on your screen.
  • Hidden Settings in Apps
  • In addition to the hidden features in the Android operating system itself, some apps also have hidden settings or features that are not readily accessible to the user. For example, the Google Chrome browser has a hidden “flags” menu that allows you to modify various experimental settings, such as enabling dark mode, disabling autoplay videos, or changing the default download location.
  • To access the flags menu in Chrome, type “chrome://flags” in the address bar and press enter. You will then see a list of experimental settings that you can enable or disable. However, be careful when modifying these settings, as they may cause the app to become unstable or behave unexpectedly.
