How to turn on the developer mode on Xiaomi Redmi Note 4: secrets MIUI

The Xiaomi Redmi Note 4 is one of the most popular smartphones among users who value balance of price and performance, but not all owners know that under the hood of MIUI hidden a powerful tool for fine-tuning โ€” the developer mode. This section of the menu gives access to the functions that the manufacturer usually hides from the average user: debugging on USB, changing the animations of the system, managing background processes and even overclocking the processor (at your own risk).

Turning on the developer mode on Redmi Note 4 is a simple process, but requires attention to detail. Error at any stage can lead to system failures or even locking the device. In this article, we will discuss not only the standard method of activation, but also alternative methods for cases where the โ€œsettingsโ€ menu behaves incorrectly, and you will also learn which settings in the developer mode are really useful for everyday use, and which are better not to touch without urgent need.

Why do I need a developer mode on Xiaomi Redmi Note 4?

Many users mistakenly believe that the developer mode is only necessary for programmers or those who are engaged in the firmware of smartphones, in fact, even the average user can use it for:

  • ๐Ÿ”ง Acceleration of the system โ€“ disabling unnecessary animations and background processes saves battery power and increases the responsiveness of the interface.
  • ๐Ÿ“ฑ Unlocking the bootloader is the first step to install custom firmware or obtain root rights.
  • ๐Ÿ”Œ Debugging by USB โ€” This is not something that can be done when connecting to ADB or flashing through a computer.
  • ๐ŸŽฎ Emulation of location is useful for games like Pokรฉmon GO or testing geo-dependent applications.
  • ๐Ÿ“Š Performance monitoring โ€“ in real time you can track the load on the CPU, GPU and operational memory.

Not all functions are equally useful, however, such as changing DPI parameters can cause some applications to display interface elements incorrectly, and activating dummy locations sometimes blocks access to banking applications due to a security trigger.

โš ๏ธ Attention: Setting the Background process limit below the Standard can lead to spontaneous closure of messengers and social networks. The optimal value for Redmi Note 4 is โ€œStandardโ€ or โ€œMaximum 4 of the processยป.

Standard way of inclusion: step-by-step instructions

The most reliable method of activating developer mode on Redmi Note 4 is through the About Phone menu, which works on all versions of MIUI (including MIUI 8/9/10/11/12) unless the system has been heavily modified.

  1. Open the Settings app (the gear icon on the home screen or in the app menu).
  2. Scroll down and select About Phone (sometimes called About Device).
  3. Find the line MIUI version and tap it 7 times in a row, after the first 3-4 clicks will appear pop-up notification with the countdown of the remaining taps.
  4. After pressing 7, the system will show a message: โ€œYou are a developer!โ€ โ€“ this means that the hidden menu is unlocked.
  5. Return to the main Settings menu, and a new section will appear โ€” Additional โ†’ Developers (or just Developers in newer versions of MIUI).

If nothing happens after 7 taps, check:

  • ๐Ÿ“ฑ Is there a shell from a third-party manufacturer on the phone (for example, Flyme or ColorOS).
  • ๐Ÿ”„ Are the gestures off? MIUI โ€” Sometimes they block tap registration.
  • ๐Ÿ› ๏ธ Is the firmware not damaged (in this case, resetting to factory settings can help).

Alternative Incorporation Methods (if Standard Incorporated Does Not Work)

On some firmware (especially custom or heavily modified ones), the standard method may not work, in which case try one of the alternative methods:

Method 1: Through ADB (for power users)

If you already have ADB drivers installed and USB debugging enabled (for example, on another device), you can activate the developer mode with the command:

adb shell am start -n com.android.settings/.DevelopmentSettings

After completing this command, the developer menu will open, even if it has been hidden.

Method 2: Resetting settings (extreme case)

If the system is glitchy and does not respond to taps according to MIUI, try:

  1. Make a backup of the data.
  2. Go to Settings โ†’ Additional โ†’ Recovery and Reset.
  3. Select Resetting (without deleting files).
  4. After the reboot, repeat the standard procedure for turning on the developer mode.

โš ๏ธ Attention: Use ADB Forcing the developer mode to be enabled may cause system applications to fail if the firmware has been modified by third-party tools (such as Magisk or Xposed). MIUI via Fastboot.

What if the developer is not on the menu after resetting?
If the For Developers section does not appear after 7 clicks on the MIUI version after reset, this can mean: 1. Unofficial firmware with remote system components is installed. 2. /system/build.prop file is damaged. 3. Demo Mode (demo mode for stores) is activated. In this case, only a complete flashing through the Mi Flash Tool with the choice of Clean All option (erase all data!) will help.

Top.-5 Useful settings in developer mode for Redmi Note 4

When you activate the developer mode, you will see dozens of options, and we have selected the most useful ones for Redmi Note 4 that will not harm the system, but will significantly improve the user experience:

How to turn off the developer mode (and should I?)

Many users are wondering whether it is worth turning off the developer mode after use, on the one hand, it does not consume additional resources and does not affect performance, on the other hand, some settings (for example, debugging over USB) can pose a security threat if the phone falls into the wrong hands.

To deactivate the developer mode:

  1. Go to Settings โ†’ Additional โ†’ For developers.
  2. In the upper right corner, press the switch (it will turn gray).
  3. Confirm the disconnection in the dialog window.

But remember, once you turn off, all the settings you've changed will reset to default values, so if you want to just hide the developer menu from prying eyes, but keep the settings, you just need to:

  • ๐Ÿ”’ Set a password to enter Settings (via Security) โ†’ Application lockdown).
  • ๐Ÿ“ฑ Disable the display of the section in the main menu (some firmware has the option โ€œHide for developersยป).

๐Ÿ’ก

Turning off developer mode doesn't affect the performance of the phone, but resets all user settings in this section. If you connect to ADB frequently, it's best to leave the mode on, but protect access with a password.

Frequent mistakes and their solutions

When working with the developer mode on Redmi Note 4, users often face typical problems, and here are the most common ones and ways to fix them:

Error 1: โ€œYou are already a developerโ€ but the menu doesnโ€™t appear

This is due to a failure in the system cache.

  1. Go to Settings โ†’ Applications โ†’ All applications.
  2. Find the Settings app and clear its cache.
  3. Restart your phone and check for the developer menu.

Error 2: After enabling debugging via USB, the computer can't see the phone

The problem is usually due to a lack of drivers or locking on the Windows side.

  • ๐Ÿ–ฅ๏ธ Mi drivers installed PC suite ADB Drivers.
  • ๐Ÿ”Œ Try another one. USB-cable (preferably original).
  • ๐Ÿ”„ Include in the developer menu option Cancel authorization USB-Debugging and reconnecting the device.

Error 3: Developer Settings Reset After MIUI Update

This is normal system behavior. After major updates (like MIUI 10 to MIUI 12), the developer mode is turned off for security reasons, and you have to turn it back on as standard.

Why are some settings grey and inactive?
Some options in the developer menu may be blocked: - If the device is tied to a Mi Account with active Find Device function. - If you have limited-enabled firmware installed (e.g., the corporate version of MIUI). - If the phone is in Safe Mode mode. To unlock them, unplug your Xiaomi account or swipe the full MIUI version through Fastboot.

Security: What developer settings can harm you?

Developer mode is a powerful tool, but with great power comes great responsibility.

  • ๐Ÿ”“ Reduce data protection โ€“ for example, disabling device encryption.
  • ๐Ÿ“‰ Deteriorating productivity โ€“ wrong settings CPU may cause overheating.
  • ๐Ÿšซ Abloding system applications โ€“ changing access rights without knowing the consequences.

The following options are particularly dangerous:

Setting upRiskEffects of consequences
Allow fictitious locationsHigh-pitchedBlocking banking applications, problems with geolocation
Disable application rights checkcriticalVulnerability to malware
Forced shutdown of system applicationsHigh-pitchedUnstable MIUI operation, departures

If you accidentally changed your critical setting and your phone is not working properly, try:

  1. Return the parameter to the default value (if the system is still responsive).
  2. Reset your settings via Recovery (without data loss if you choose Wipe Cache).
  3. In extreme cases, reflash the device through the Mi Flash Tool.

FAQ: Answers to Frequent Questions

Can I turn on the developer mode on Redmi Note 4 without clicking on the MIUI version?
Yes, but only through ADB or third-party applications like QuickShortcutMaker, but these methods require pre-activation of debugging over USB, which is impossible without the developer mode itself, so the standard method remains the only universal one.
Why did the phone stop after the developer mode was turned on?
You may have changed the parameters of the background limit to too low or activated the GPU-Accelerate for unsophisticated applications. Return settings to standard and restart the device. If the brakes are still there, clear the cache to Settings. โ†’ Memory. โ†’ Cleanup.
Can I turn on the developer mode on the blocked Redmi Note 4?
No. If your phone is locked with a pattern lock or password and you don't remember it, you'll have to reset it with Recovery first. Only then you can activate the developer mode in the standard way.
How to save the developer settings after resetting the phone?
The developer mode settings are not saved in MIUI backups. The only way to migrate them is to manually write down all the changed settings and then reset them again. You can use screenshots with settings to speed up the process.
Is it safe to keep the developer mode on all the time?
Yes, the fact that a developer mode is on doesn't affect security or performance, but only when you change specific parameters (such as USB debugging in public places), and if you haven't changed critical settings, you can leave the mode activated.
