Why Developer Mode Can Be Dangerous and When to Turn It Off
The developer mode feature in Xiaomi, Redmi and POCO smartphones gives you access to hidden system settings that are usually hidden from the average user. These settings allow you to test new features, debug applications and optimize performance. However, activating developer mode reduces the security level of the device, as some settings can disrupt the stability of the OS or even lead to data leakage.
It is recommended to turn off this mode in several cases: if you accidentally activate it (for example, repeatedly clicking on the build number in the settings), if you transfer the phone to another person, or if you notice a malfunction in the device after changing hidden parameters.
It's important to understand that simply hiding a Developer Menu item is not like completely shutting down the mode. The system continues to operate in a "develop" state until a reset or a dedicated command is performed. Next, we'll go through all the available methods, from the simplest to the radical.
Method 1: Disconnect via settings (without data reset)
If you want to remove the developer menu from the visible settings list but are not ready to reset the device to factory settings, use this method.It works on most Xiaomi models with a MIUI shell (including versions 12, 13 and 14) and requires no special knowledge.
Instructions:
- π± Open the Settings app on the main screen.
- π Scroll down and find the About Phone section (or About the device on some models).
- π Tap 7 times in a row on the item Version MIUI. The system will show a notification: You are already a developer!".
- βοΈ Go back to the main settings menu and check β the Developer section should disappear.
This method doesn't shut down the developer mode completely, it just hides it from the interface. Any changes you make to your developer settings (like USB debugging enabled or OEM unlocked) will stay active.
π‘
If after 7 taps nothing happens, try tapping on the item Assembly number (on some firmware).
Method 2: Completely disable via resetting (without data loss)
If you need to deactivate developer mode completely, but you donβt want to lose personal files, photos or apps, use a partial reset.This method removes all system settings, including the developerβs settings, but saves user data.
Step-by-step:
- Open Settings β About the phone β Reset settings.
- Select Resetting (not to be confused with Delete All Data!).
- Confirm the action by entering a pattern lock or PIN-code.
- Wait for the device to restart (it will take 2-5 minutes).
Make sure your battery is over 50% charged |Save backups of important files (just in case) |Remember passwords from Mi and Google |Disable two-factor authentication for 10 minutes (if enabled)
-->
After the reboot, check that the Developer For Settings item is not available. If it still shows up, it means that the reset was incorrect, try repeating the procedure or use the third method.

A partial reset does not remove applications, but returns all system settings to factory values, including developer parameters.
Method 3: Radical shutdown (full reset to factory settings)
It's the most reliable, but also the most radical, method, which is guaranteed to turn off the developer mode, but it deletes all data from the device, including apps, photos and accounts, and only use it if:
- π§ Selling or transferring your phone to another person.
- π The device is unstable due to changes in the developer settings.
- π You need to return the smartphone to a βcleanβ state (for example, before warranty repairs).
Instructions:
- Go to Settings β About the phone β Reset settings.
- Select Delete All Data (Reset to Factory).
- Confirm the action and wait until the process is completed (it can take up to 10 minutes).
What to do if the phone is stuck when reset?
After a full reset, the developer mode will be disabled, and all hidden settings will return to the default values. Remember that to re-activate the mode, you will need to re-do 7 clicks on the MIUI version.
Yeah, when you study settings.|No, never.|Yeah, but it was quick.|I don't know what that is.-->
Table: Comparison of methods for deactivating the developer mode
| Method | Data retention | Total shutdown | Difficulty | Implementation time |
|---|---|---|---|---|
| Hiding in 7 taps | β Yes. | β No (only hides the menu) | β Very simple. | 1 minute |
| Resetting (partial) | β Yes. | β Yes. | ββ Just | 5-10 minutes |
| Full discharge (factory) | β No. | β Yes. | βββ Middle-Average | 10-15 minutes |
| ADB Team Team | β Yes. | β Yes. | ββββ Hardly. | 15-20 minutes |
As you can see from the table, the fastest way is to hide the menu through 7 taps, but it does not guarantee complete deactivation. For a one hundred percent result without losing data, a partial reset is suitable.
Additional method: Disconnect via ADB (for power users)
If youβre familiar with the developer tools, you can turn off developer mode via Android Debug Bridge (ADB), a method that works for Xiaomi models where standard methods donβt work (like some POCO or Redmi firmware with custom builds).
Instructions:
- Install. ADB-computer-driver.
- Enable USB debugging in the developer settings on your phone.
- Connect your smartphone to your PC and execute the command in the terminal: adb shell settings put global development_settings_enabled 0
- Reset the device.
Once the developer menu is executed, it disappears and all associated settings reset, a method that requires caution β improper use of ADB can lead to system failures.
π‘
Before using ADB, check that the phone has enabled the option to Allow debugging over USB in the developer settings.
What to do if the developer mode is not turned off?
Sometimes users are faced with a situation where none of the methods work, and here are the possible causes and solutions:
- π Error firmware: If you use custom firmware (like LineageOS or Pixel Experience), some system commands may not work. MIUI via Fastboot.
- π Manufacturer Block: On some models (e.g. Xiaomi) 12T Pro or Redmi Note 11 Pro+) The developer mode can be protected from shutdown, and then only a complete reset will help.
- π± Hardware failure: If the phone doesn't respond to reset commands, memory or firmware may have been damaged.
If none of these methods worked, try updating your firmware to the latest version through Settings β System Update. Sometimes developer mode bugs are fixed in new MIUI builds.

On devices with an unlocked bootloader, the developer mode can automatically turn on after the update, in which case it must be turned off again.
