How to install the default app on Xiaomi

Modern Xiaomi smartphones, which are based on MIUI shells or the new HyperOS, provide users with a wide range of personalization tools. One key feature is the assignment of default programs, which allows you to automate the opening of links, calls, messages and media files. Without the right setup, the system will ask each time what you want to use, which can be annoying when you use the device often.

The procedure for installing preferred software can vary depending on the version of the Android operating system and the specific firmware modification. Owners of Redmi and Poco devices should also consider the features of their interfaces, which sometimes hide the desired menu items deeper than in the standard versions. Understanding the logic of the system will allow you to effectively manage the digital environment.

In this guide, we will look at all the nuances of customization, from standard methods to solving problems when the system does not allow you to change the choice, you will learn where to look for hidden settings and how to avoid the typical errors that lead to interface failures.

Why you need to assign applications by default

Default application assignment is a fundamental operating system mechanism that determines which software product will run automatically when a particular action is performed. For example, when you click on a link in a messenger, the system must know whether to open it in Chrome, Yandex Browser or another browser. If this option is not specified, the user faces constant dialog boxes of choice.

In addition, the default launcher allows you to completely change the visual style of the desktop, adding new gestures, widgets and animations that are not available in the standard shell of MIUI. This is especially true for enthusiasts who prefer pure Android or specific interfaces like Nova Launcher. Without fixing the status of “default” system will constantly return you to the native interface.

⚠️ Warning: Uncontrolled installation of unknown launchers or system utilities as the main ones can lead to unstable interface operation or cyclical reboots if the application contains errors.

Process automation gives you access to more advanced use cases, such as integration with smart homes or specialized work profiles, and when you clearly state your preferences, it starts to work faster because it doesn't waste resources processing program selection requests, which is especially important for devices with limited RAM.

Where are the application settings in MIUI and HyperOS

Finding the right menu in Xiaomi smartphones may not be obvious because of the deep nesting of settings. In current versions of shells, the path to managing priorities often lies through the Settings section, then you need to select the App item, and this is where you focus on managing all installed programs and system services.

Inside the Apps section, you should find the App Settings or Application Management subsection, where the top corner of the screen (usually at the top right) contains a three-dot menu. Clicking on it will show a drop-down list that contains the default App item you want. In some versions of HyperOS, this item can be displayed in a separate menu, "Special Features" or "Extended Settings".

An alternative and often faster way to get to the menu is to use built-in search by settings. Just click on the magnifying glass at the top of the settings screen and type in a "default apps" or "default apps" request, and the system will prompt you to go to the desired section, which saves time and eliminates the need to wander through the menu.

💡

Use the voice assistant if it is configured and say “Open Default App Settings” to instantly get to the desired menu without manual search.

Step-by-step: how to choose a browser and launcher

The process of installing the main browser or launcher is the most popular among users. First, go to the default menu of the Applications, which was discussed above, and you will see a list of categories such as Browser, Desktop (Luncher), Phone, Messages and others.

Click on the category you want to change, like the Browser. The system will offer a list of all compatible apps installed on your device. Choose the desired option, like Firefox or Opera. Once selected, the system will no longer ask you than open links, and will immediately launch the selected browser.

Similarly, you set up your desktop, and if you set up a third-party launcher, it will appear in the Desktop category list, and if you choose it, you activate the new interface, but for security reasons, MIUI may show a warning that using third-party launchers may affect some of the features.

It is important to note that for some system features, such as Phone or Messages, replacing standard Xiaomi apps may be limited, and in such cases, there will only be one available application on the list, and you will not be able to change it without obtaining superuser rights (Root).

Set up default actions for file types

Special attention should be paid to setting actions for specific types of files, such as video, audio or documents. Often users are faced with a situation where the video is opened in the wrong player, and PDF-files are run in the browser instead of a convenient reader, and the management of these parameters is also in the general menu of application settings.

Some versions of firmware have a detailed Open by default menu inside the settings of a particular application. Once you go into the software's properties, you can see a section that lists all the file types it supports, and you can force resets or, conversely, pin the association.

If you want all images to open in Google Photos instead of the standard Xiaomi Gallery, you need to find the Images category in the Action List and choose your preferred app, which allows you to create a fully personalized media environment on your device.

What to do if the system does not change the choice

Quite often, users are faced with a situation where the default application selection point is inactive (serious) or the system ignores the choice by returning a standard application, this often happens after a firmware update or when using aggressive memory optimizers built into MIUI.

The first step to solve the problem is to clean the cache and data of the Security or Settings app itself, as they control these policies. Go to Settings → Apps → All Apps, find the system settings app and click Clear → Clear all data. Don’t be afraid, your personal files won’t be affected.

⚠️ Note: Resetting system application data can bring some interface settings (wallpaper, icon location) back to factory values, so be prepared for a little re-configuration.

Another reason for blocking may be the “Safe Mode” feature enabled or the presence of viruses that replace system processes. Check the device with an integrated security scanner. Also make sure that the alternative application has all the necessary permissions to work as the main one.

Resetting application settings by default

If you get confused or an application starts to behave incorrectly, performing actions that were not intended for it, the best solution is a complete reset of preferences, which will return the system to the state where it asks the user at every action than to open a file or link.

To perform the reset, go to Settings → Apps → All Apps. In the upper right corner, click on three dots and select Reset App Settings (or Reset Preferences). Confirm the action and all previously established file associations will be deleted.

After this procedure, when you first start a video or open a link, you'll see the "What to open?" dialog box again, where you can select a new application and, if you want, tick "Always" to fix the choice again, which is a great way to "refresh" the system without completely reinstalling the software.

💡

Resetting preferences is a secure operation that does not delete your personal data, photos or contacts, but only resets the logic of opening files.
