Have you ever noticed a strange package called com.xiaomi.misettings on your Xiaomi smartphone? or have you stumbled upon it in the system logs, in the developer’s settings, or while searching for hidden features? This is not a virus or superfluous software – it is one of the key system components that is responsible for the operation of hidden settings and service menus on Xiaomi, Redmi and other devices. POCO.
Unlike the standard settings menu (com.android.settings) you see every day, com.xiaomi.misettings has advanced settings that are not available to the average user. Here you can find tools for testing hardware components, debugging the network, calibrating sensors and even features that the manufacturer has hidden "just in case." But why does this package not have a familiar icon in the application menu? And can it be safely removed? Let's sort it out.
What is com.xiaomi.misettings and why you need it
com.xiaomi.misettings is a system application that is responsible for the service menu and engineering settings on Xiaomi devices. It is closely integrated with the firmware. MIUI and grants access to:
- 🔧 Testing of hardware components (display, camera, speakers, microphone, accelerometer, etc.).
- 📡 Hidden network parameters (modulation modes) 4G/5G, Wi-Fi settings, Bluetooth Low Energy).
- 🔄 Calibration of sensors (gyroscope, compass, proximity sensor).
- 🛠️ Tools for service centers (resetting meters, authentication of components).
In fact, it’s a back door for engineers and developers, but some features can be useful for ordinary users, such as manually switching modems if the smartphone is not catching the network, or checking the real state of the battery without third-party applications.
It's important to understand that com.xiaomi.misettings is not a standalone application in the usual sense, but a system service that runs on special commands or through an engineering menu, and it can't be opened with a simple tap on the icon, because there's no icon.
- 📱 Codes USSD (For example, #4636## for battery information).
- 🖥️ ADB-commands (e.g. am start) -n com.xiaomi.misettings/.MainSettings).
- 🔗 Hidden gestures (for some models).
⚠️ Note: Not all features in com.xiaomi.misettings are documented, and some parameters can cause the device to function in an unstable manner if changed without understanding the consequences. For example, improper calibration of the proximity sensor can cause problems with automatically turning off the screen during calls.
How to open com.xiaomi.misettings on Xiaomi, Redmi or POCO
Because it's a system component, you can't run it in the standard way, but there are some proven methods that work on most devices with a computer. MIUI 12–14:
Method 1: Through USSD-codes (the simplest)
Enter the Phone application with one of the following codes:
- #4636## - battery information, usage statistics, network tests.
- ##6484## - Test of hardware components (camera, speakers, vibration).
- #64663## – check the operation of sensors (accelerometer, gyroscope, compass).
After entering the code, the corresponding menu com.xiaomi.misettings will automatically open.
Method 2: ADB (for advanced users)
If USSD-codes do not work (for example, they are blocked on some firmware), you can use Android Debug Bridge (ADB):
- Turn on the debugging. USB in the developer settings (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional settings → For developers).
- Connect your smartphone to your PC and execute the command: adb shell am start -n com.xiaomi.misettings/.MainSettings
This will open the main menu of hidden settings, from where you can go to any section.
Method 3: Through Third Party Applications (Alternative)
If the first two methods don’t work, you can use applications like MTK Engineering Mode (for MediaTek processor devices) or QuickShortcutMaker:
- Install QuickShortcutMaker from Google Play.
- In the search, type misettings.
- Select com.xiaomi.misettings.MainSettings and create a shortcut on the home screen.
⚠️ Note: On some models (e.g. Xiaomi) 12T or POCO F5) Access to com.xiaomi.misettings may be restricted by the manufacturer, in which case, trying to open the menu will result in the error "This activity is not available.
What features are hidden in com.xiaomi.misettings
Depending on the device model and version MIUI, You can find different tools on this menu. Here are the most useful ones:
| Section | What can I do? | Potential risk |
|---|---|---|
| Battery Information | Find out the real capacity of the battery, the number of charging cycles, temperature. | There is no risk (only reading the data). |
| Network Testing | Forced to switch the network to 2G/3G/4G/5G, signal-test. | It can disrupt the stability of the connection if you choose the wrong mode. |
| Sensor Calibration | Calibrate the gyroscope, the accelerometer, the compass. | Incorrect calibration will cause game and navigation problems. |
| Hardware Testing | Check the camera, speakers, microphone, vibration. | There is no risk (only testing). |
| MIUI Hidden Features | Enable experimental functions (e.g., Ultra Battery Saver mode). | It can cause unstable operation of the system. |
One of the most popular sections is Battery Information, which shows the actual battery capacity per mAh (rather than the wear rate as standard settings). For example, if your Redmi Note 11 originally had a 5,000 mAh battery and here it shows 4200 mAh, it's time to think about replacing it.
Another useful feature is Network Testing, which is if your smartphone is not catching well. 4G, You can manually switch to a different modulation mode or even lock down certain frequencies that don’t work well in your area.

Can I delete com.xiaomi.misettings and what happens if I do?
You can technically delete this app, but you shouldn't.
- 🚨 Disruption of the system: many functions MIUI depend on com.xiaomi.misettings, for example, automatic sensor calibration or network diagnostics.
- 🔄 Problems with updates: the next update MIUI The system can restore a deleted packet, but with errors.
- 🛠️ Loss of access to hidden settings: you will not be able to use USSD-code ADB diagnostic.
If you are disturbed by this application (for example, it takes up space or appears in logs), it is better to disable it, not delete it. ADB:
adb shell pm disable-user --user 0 com.xiaomi.misettingsTo get it all back, do this:
adb shell pm enable com.xiaomi.misettings⚠️ Note: On some devices (e.g. Xiaomi 13 Pro or X-rays) POCO X5) Disabling com.xiaomi.misettings may cause Google Play Services to malfunction.If push notifications or geolocation stop working after the shutdown, return the packet to active immediately.
com.xiaomi.misettings vs com.android.settings: What's the difference?
Many people confuse com.xiaomi.misettings with the standard settings app com.android.settings. The difference between the two is fundamental:
| Parameter | com.android.settings | com.xiaomi.misettings |
|---|---|---|
| Type | The basic settings of Android (Google). | Hidden settings Xiaomi (manufacturing). |
| Access. | The badge is on the app menu. | Only through codes, ADB ore-menu. |
| Functions | Wi-Fi, Bluetooth, sound, display, etc. | Iron testing, sensor calibration, network diagnostics. |
| Risk of change | Minimum (custom settings) | High (may disrupt the system). |
Simply put, com.android.settings is what you see every day, and com.xiaomi.misettings is a basement with tools for engineers. The average user needs the first package always, and the second package only in rare cases (for example, for troubleshooting).

- 📵 Loss of mobile network (if you change the modem settings).
- 🎮 Gambling failures (with incorrect gyroscope calibration).
- 🔋 Fast battery discharge (if you include experimental energy saving modes).
To minimize the risks:
- 📌 Do not change the parameters, the purpose of which you do not know.
- 📌 Backup before experimenting (via Settings) → System system → Backup).
- 📌 Use only verified sources (official Xiaomi documentation or topic forums like the one you see here) XDA Developers).
💡
