How to change the application icon on Android without a launcher: a complete guide

Replacing standard application icons on Android is a popular way to personalize your smartphone. Many users believe that this requires a third-party launcher like Nova Launcher or Action Launcher, but this is not so. There are legal methods for changing icons without installing additional software, although they require more effort and have limitations.

In this article we will look at three working methods: through the system settings (not available on all devices), with the help ADB commands for experienced users, and by manually editing APK files. Each option has its pros and cons - from simplicity to the risk of disrupting the application. It is important to understand that manufacturers (for example, Samsung, Xiaomi, Huawei) often block such changes at the firmware level.

If you are ready to experiment, let's get started. But first, check whether your device supports at least one of the described methods.

1. Changing icons through Android settings (limited support)

Some versions of Android (starting from Android 8.0 Oreo) allow you to change icons for individual applications through standard settings. This method is the simplest, but does not work on all smartphones. Most often, it is available on “pure” Android (for example Pixel, Nokia, Motorola) or devices with minimal modifications from the manufacturer.

To check whether your phone supports this method:

1. Long-press your finger on the application icon on the main screen.
2. In the menu that appears select Edit or Edit (on some devices - Icon settings).
3. If the option appears Change icon —you're in luck. If not, proceed to the following methods.

On smartphones Samsung with shell One UI or Xiaomi s MIUI this method is usually blocked. In such cases, the system either does not show the menu item or only offers to change the shortcut, but not the icon itself.

2. Using ADB to replace icons (for advanced users)

The method with Android Debug Bridge (ADB) is suitable for those who are ready to work with the command line. It allows you to change the application icon by modifying its data via a PC. Important: this method requires USB debugging permissions and may not work on all devices due to manufacturer restrictions.

Step-by-step guide:

1. Install ADB drivers on your PC and enable USB debugging in the developer settings on your phone (Settings → About phone → Build number - press 7 times).
2. Connect the phone to the PC and run the command:

   adb devices

   To make sure that the device is recognized.

3. Download the icon in format .png (size 192×192 or 512×512 pixels) and place it in a folder on your phone, for example, /sdcard/Download/custom_icon.png.
4. Run the command to replace the icon (replace com.example.app to the package name of your application):

   adb shell pm set-icon --package com.example.app --icon-path /sdcard/Download/custom_icon.png

This method has critical limitations:

• 🚫 Works only on Android 10+ with command support pm set-icon (many manufacturers block it).
• 🔄 After updating the application, the icon may reset.
• ⚠️ An incorrect command can cause the application to crash.

USB debugging is enabled

ADB drivers are installed on the PC

A new icon has been downloaded in PNG format

Know the package name of the application (you can find out through the Play Market or APK analyzer)

-->

⚠️ Attention: ADB commands provide low-level access to the system. If you have never worked with them, practice on an unnecessary application or create a backup copy of the data.

3. Manual editing of the APK file (the most universal, but difficult method)

If the previous methods did not work, the most reliable but time-consuming option remains - changing the app's APK fileFor this you will need:

• 📱 Root access (not necessary, but simplifies the process).
• 💻 APK decompilation app (for example, APKTool or JADX).
• 🖼️ New icon in format .png with the correct resolution.
• 🔧 Ability to work with the Android file structure.

Action algorithm:

1. Download the APK file of the application (you can via APK Extractor from the Play Market or from the site APKMirror).
2. Decompile the APK using APKTool:

   apktool d app.apk -o output_folder

3. In the folder output_folder/res find the icon files (usually in drawable or mipmapReplace them with your own, keeping the original names.
4. Compile the APK back:

   apktool b output_folder -o modified_app.apk

5. Sign the new APK (for example, via Uber Apk Signerand install it on your phone.

This method is guaranteed to work on 90% of devices, but requires technical skills. The main disadvantage is that when updating the application through the Play Market, your changes will be lost, and the procedure will be lost. you will have to repeat.

What to do if the APK does not install?

If the APK is not installed after modification, check:

1. The signature is correct (use the same certificate as the original application, if possible).

2. Version targetSdkVersion v AndroidManifest.xml - on new Androids the installation of old APKs may be blocked.

3. Presence of conflicts with an already installed version (uninstall the original before installing the modified APK).

4. Alternative methods: shortcuts and widgets

If all the above methods are not suitable, you can make a compromise - create a shortcut with a custom icon. This will not change the application icon itself, but will allow you to place an alternative icon on the main screen that will open the desired app.

How to do this:

1. Install an application to create shortcuts, for example, Shortcut Maker or QuickShortcutMaker.
2. Select the target application and specify the path to its main activity (usually the application itself determines the correct path).
3. Upload your icon and save the shortcut on the main one screen.

Advantages of the method:

• ✅ Works on any devices without root and ADB.
• ✅ Does not require modification of system files.
• ✅ You can create several shortcuts with different icons for one application.

Disadvantages:

• 🚫 The shortcut is a separate element, and not a replacement for the original icon.
• 🔄 If you delete the original application, the shortcut will stop working.

5. Manufacturer restrictions: why you can’t change the icon

Many brands artificially block the ability to change icons. Here is how it is implemented by popular manufacturers:

Manufacturer	Shell	Support for changing icons	Workarounds
Google	Pure Android	Partial (via settings or ADB)	All described methods
Samsung	One UI	None	Only shortcuts or manual APK editing
Xiaomi	MIUI	Absent	ADB may not work, only APK modification
Huawei	EMUI	Absent	Shortcuts or full flashing
OnePlus	OxygenOS	Partial (via ADB)	Methods 2 and 3

Manufacturers motivate blocking with “security concerns” and “uniformity of the interface.” In fact, this is also a way to tie users to branded services (for example, topics in Samsung Themes or MIUI Themes).

⚠️ Attention: On devices with a locked bootloader. (most smartphones Xiaomi i Huawei) modification of system APKs can lead to the phone being bricked. Before experiments, check the status of the bootloader with the command fastboot oem device-info.

6. Risks and how to avoid them

Any interference with system files or APK carries potential risks. Here are the most common problems and ways to prevent them:

• 💥 The application stops launching - this happens if you incorrectly modify AndroidManifest.xml or sign the APK. Always test on non-critical applications.
• 🔒 Locking your Google account —rare, but happens when system APKs are modified (for example, Google Play Services). Do not touch applications signed by Google.
• 📱 Reset settings —on some devices (especially Samsung), an unsuccessful modification may cause a factory reset. Make a backup via adb backup or Titanium Backup.

To minimize risks:

• 📌 Use backups (for example, via Swift Backup to root users).
• 🛠️ Start with non-system applications (for example, games or instant messengers).
• 🔍 Check error logs via adb logcatif something went wrong.

adb pull /system/priv-app/Settings/ Settings_backup

This will help restore the original version in case of failure.-->

7. Frequently asked questions

Is it possible to change the icon of a system application (for example, "Settings" or "Phone")?

Technically yes, but this requires root access and modification of the system files in the folder /system/priv-app/. Without root, access to these folders is blocked. On devices with an unlocked bootloader (for example, Google Pixel) this is easier to do than on Samsung or Xiaomi.

Important: changing system APKs can lead to cyclic reboot (bootloop) if you make a mistake with the signature or file structures. We recommend that you first practice using custom firmware in the emulator.

Why does the icon reset after updating the application?

When updating via Google Play a new version of the APK is installed, which overwrites all your changes. To avoid this:

1. Disable auto-update for this application in Play Market.
2. Use modified versions of the APK (for example, from APKMirror), but be aware of the security risks.
3. Create a shortcut with a custom icon (method 4) - it does not depend on updates.

Are there applications that make it easier to replace icons without a launcher?

Yes, but there are few of them, and they do not work on all devices. For example:

• Icon Changer — allows you to replace the icon by creating a shortcut.
• X Icon Changer —requires Xposed Framework (works only on older versions of Android).
• Tasker —you can set up automatic changing of icons through scripts (difficult for beginners).

Most of these applications either create shortcuts or require root. They do not provide a full replacement of icons without restrictions.

How to find the batch name of the application for ADB commands?

There are several ways:

1. Through Play Market: open the application page in the browser - the batch name will be in the URL after id= (for example com.whatsapp for WhatsApp).
2. Via ADB:

   adb shell pm list packages | grep "application_name"

3. Through applications like App Inspector or Package Name Viewer.

Is it possible to return the original icon if something went wrong?

Yes, here's how to do it depending on the method:

• If used ADB:

  adb shell pm set-icon --package com.example.app --icon-path ""

  (an empty path will reset the icon to the original).

• If modified APK - reinstall the original version from Play Market.
• If created shortcut - just delete it.

If after modifying the APK the application stops running, delete it and install the original version. As a last resort, resetting the settings will help (but this will delete all data).
