Every smartphone owner is faced with a situation where, when you click on a link, the wrong browser opens that you prefer, or when charging the device, the system prompts you to select a strange application for power management. This happens because the system Android did not have a “default” application installed for a specific action, or the choice was made accidentally and was permanently fixed.

Understanding how to manage these settings is critical for comfortable use of the gadget. Properly configured default applications ensure smooth operation of the interface, instant launch of the necessary apps and the absence of annoying pop-up windows with action selection. In this article, we will analyze in detail the mechanisms of the system and learn how to change app priorities.

Many users do not even suspect that their smartphone is capable of automatically performing routine tasks through the tools you choose. For example, opening maps when you receive an address in a message or launching a video player when you click on a file. The Android system remembers the last confirmed choice with the “Always” checkbox, ignoring other installed apps. Changing this scenario is easy if you know where to look for the corresponding switches.

What are default applications and why you need them

Default applications are apps that the operating system launches automatically when certain actions are performed without additional question to the user. When you click on a phone number in your contacts, the system must know which dialer to make the call through. If there are several such apps, a conflict of priorities arises.

The main purpose of this function is to optimize the user experience. Imagine if every time you opened a photo you had to choose between gallery, editor and cloud storage. This would take too much time. Purpose of the main application eliminates this redundancy, making interaction with the device intuitive.

However, the flexibility of the platform Android allows you to change these settings at any time. Unlike closed ecosystems, here you can install a third-party browser as your main browser, replace the standard keyboard with a more functional one, or use an alternative launcher to change the appearance of your desktop.

💡

If you accidentally click “Always” when selecting an application, don’t panic. This action can be easily canceled in the system settings in a couple of seconds without losing data.

System restrictions may vary depending on the OS version and the manufacturer's shell. On some models Xiaomi or Samsung paths to settings may differ from the “clean” Android on smartphones Google Pixel. Always check the current interface of your device, as manufacturers often modify the menu.

How to reset an application selection if it was made by mistake

The most common problem is that the user accidentally selects the wrong app and checks the “Always” box. To fix this, you need to force a reset for a specific activity. This will return the system to a state where it will ask you for preferences again.

The reset process is universal for most versions Android. You need to find the application that currently opens by default (for example, the Chrome browser, although you want Yandex), and clear its “default” status. After this, the next time you launch a file or link, a familiar selection window will appear.

The algorithm of actions is as follows:

  • 📱 Go to Settings your smartphone and find the section Applications or All applications.
  • 🔍 In the list, find the app that is currently not working correctly (for example, the browser that opens instead of the one you need).
  • ⚙️ Click on it, scroll down to item Open by default or Launch by default.
  • 🗑️ Click the button Delete default settings or Reset preferences.

☑️ Reset algorithm

Done: 0 / 4

After completing these steps, the system will “forget” your previous choice. Now, the next time you try to open a link or file, a menu will appear on the screen with the question “What to open?”. Just select the desired application and click “Always” to lock in the new priority.

Customizing the home screen and launcher

The launcher is perhaps the most important application in the system, as it is responsible for displaying the desktop, icons and widgets. Replacing the standard launcher allows you to completely transform the appearance of your smartphone, add gestures and change the operating logic.

To select a new launcher as the main one, first install it from the store Google Play. Popular options are Nova Launcher, Microsoft Launcher or Smart Launcher. After installation, press the “Home” button (circle or square in the navigation), and the system will prompt you to select an application for the main screen.

Option Standard launcher Third-party launcher
Customization flexibility Limited by the manufacturer Full freedom of action
Performance Optimized for hardware Depends on developer code
Control gestures Standard User customized
Widgets System only Third-party support

If the selection window does not appear automatically, go to the settings via path Settings → Applications → Default applications → Main application. Here you will see a list of all installed launchers. Select the one you downloaded earlier.

📊 Which launcher do you prefer to use?
Standard from the manufacturer
Nova Launcher
Microsoft Launcher
Other third-party

It is important to understand that changing the launcher does not delete your data or icons, but may change their location. Some shells, for example MIUI or OneUI, may require additional permissions for the operation of third-party desktops, such as access to accessibility features.

Selecting a default browser and instant messengers

Browser and instant messengers are apps with which we interact more often everything. Assigning a preferred browser ensures that all links from mail, social networks and documents will open in the familiar interface with your saved passwords and bookmarks.

To configure, go to the section Default applications in the main system settings. Find item Browser. Click on it and select the desired option from the list, for example, Chrome, Firefox or Yandex. Now all HTTP and HTTPS requests will be redirected there.

With messengers the situation is a little more complicated. In modern versions Android there is no single “Main messenger” switch for all types of links, since links can lead to different protocols. However, you can configure the opening of links for a specific service.

⚠️ Attention: Some news aggregator applications may try to intercept the opening of links. If you notice that links open in an incomprehensible shell application, urgently reset the default settings for this aggregator.

It is also worth checking the settings for calls and SMS. If you have several communication applications installed (for example, a standard dialer and Skype or WhatsApp), the system must clearly understand which one to launch when you click on a number in contacts. Typically, this is configured automatically the first time you make a call through the selected application.

💡

The correct choice of default browser speeds up surfing the Internet, since time is not wasted selecting a app every time you click on a hyperlink.

Managing the opening of files and media content

The Android file system allows you to open one and same file type in different ways. The video file can be launched through a standard player, through VLC or through a video editor. Music can be opened in the player or in the voice recorder.

To avoid confusion, it is recommended to designate a high-quality third-party player as the main one for audio and video. This is especially true if standard system tools do not support popular formats like MKV or FLAC. When you launch such a file for the first time, select the advanced player and confirm the action.

For documents the situation is similar. If you work with office files, install a full-fledged package, for example, from Microsoft or WPS Office, and assign it priority for files .docx, .xlsx and .pptx. This will eliminate the need to choose each time in which to open a report or presentation.

Sometimes the system may offer to open a file through cloud storage instead of a local viewer. This is convenient if the file has not yet been downloaded, but annoying if it is already in memory. Carefully read the labels in the selection window: “View” versus “Open in an application.”

Why does the system offer strange applications for opening files?

Some apps you install register themselves as viewers of all file types in order to increase their activity. This is often done by "memory cleaners" or low-quality file managers. Reset their settings to default.

Global reset of all application preferences

If the system has accumulated a lot of errors when files are opened in the wrong way, and manually going through each application seems too long, you can use the global reset function. This command will return all Open by default settings to the factory state.

To do this, go to the menu Settings → System → Reset settings (path may vary). Find the option Reset application settings or Reset application preferences. Please note: this action will not delete your data, photos or contacts, it will only forget which apps you have selected as the main ones.

Settings → System → Reset → Reset application settings

After confirming the operation, the system will reload the priority list. The next time you run any action, you will see a selection window. This is a great way to “refresh” your smartphone if it started to behave strangely after installing a lot of new software.

⚠️ Attention: A global reset will also turn off notifications for any apps you previously blocked and return camera or microphone permissions to "Prompt when in use." Be prepared to re-configure your privacy.

Frequent questions and problems during setup

Even if you strictly follow the instructions, users may encounter nuances that depend on the specific device model or firmware version. Below are answers to the most popular questions that arise when trying to select the main application.

Why is the "Remove default settings" button inactive (gray)?

This means that there are no default actions set for this application. The system simply did not remember your choice earlier, so there is nothing to reset. Try calling the action that should launch this application to make a choice first.

Is it possible to make Telegram the main application for calls?

Directly replacing the system dialer with Telegram for regular cellular calls is not possible due to Android security limitations. However, for Internet calls, you can set up links like tel: or special shortcuts, but the system will always offer a choice between cellular and IP telephony.

What should you do if, after a reset, the selection window no longer appears?

You may have accidentally pressed “Never” instead of “Always” in the past, or the system cached the error. Try clearing the application cache Android System or reboot your device. In rare cases, deleting system component updates helps. Android System WebView.

Does the choice of the main application affect battery consumption?

Indirectly - yes. If you choose a heavy, unoptimized app for frequent use (like a bad browser for opening hundreds of links a day), it will increase CPU load and reduce battery life. Choose easy and proven solutions.
