How to activate the developer mode on Xiaomi

Today’s Xiaomi smartphones have the most extensive functionality that is hidden from the eyes of the default user. This is done for security, so that inexperienced owners do not accidentally disrupt the system. However, for enthusiasts and advanced users, access to deep settings is a must, and this is where you can speed up the interface, debug the application or get root rights.

Turning on a hidden menu is the first and most important step to taking full control of your device, a simple process that requires care, as changes in system settings can affect the stability of your gadget, and in this guide, we will discuss all the nuances of activating the engineering menu on current versions of MIUI and HyperOS firmware.

Before you start, make sure you understand the implications. Developer mode gives you access to critical debugging functions. Don't change settings that you don't know what you're doing. It's key to the advanced capabilities of your smartphone, but use it wisely.

Why You Need a Developer Menu and What It Gives You

The main purpose of this Android section is to provide tools for testing applications by programmers, but ordinary users can also benefit from this, for example, you can force a dark theme to be included for applications that do not support it, or resize fonts beyond the standard limits.

One of the most popular functions is USB-It's necessary to connect the smartphone to the computer, so that you can transfer data through the computer. ADB (Android Debug Bridge. Without this, you can't install custom recavers, make a full backup of the system or flash the device in emergency mode. It also adjusts the speed of window animation, which visually makes the system more responsive.

  • πŸ”’ Unlocking the bootloader (Bootloader) for installing third-party firmware.
  • πŸ“± Forced inclusion of functions hidden by application developers.

It's important to understand that activating these features is not necessary for a phone to function normally, and if you only use your device for calls, messengers, and social media, you'll need standard settings, but if you want to get the most out of your smartphone, this section will be your main tool.

Preparation of the device for modification

Before you start manipulating system settings, you need to perform a number of preparatory steps, which will protect your data and ensure a smooth process. First of all, make sure that the battery is at least 50%. Suddenly turning off power when changing system flags can lead to errors.

It's also worth backing up important data, and while it's safe to turn on the developer menu, subsequent actions (like unlocking the bootloader) may require a complete reset, save contacts, photos and documents to the Mi Cloud or your computer, which is a standard precaution.

Another important point is that the device is linked to your Mi Account, and in modern versions of the MIUI shell, without authorization, access to some developer features may be limited, go to the settings and check if you have logged in to your profile, and if you don't have an account, you need to create one.

⚠️ Warning: Do not attempt to activate developer mode if the phone is rented or managed by a company (MDM). This may violate the organization’s security policies and result in the device being remotely locked.

Step-by-step activation instruction through settings

The easiest and safest way to open access to hidden features is through the standard settings menu. Xiaomi's interface may vary slightly depending on the Android version and shell, but the logic remains the same. You'll need to find the About Phone section and run a series of quick clicks.

First, open the Settings app and scroll to the top. Click On Phone. It shows all the basic information about the model, Android version and build number. We're interested in the MIUI version (or the OS version in the new firmware).

You need to quickly click on this item 7-10 times in a row. Make rhythmic touches, not too fast, but not slowly. After the fifth click, the system can warn you that you are becoming a developer. Continue to click until the pop-up notification "You became a developer!" appears.

What to do if the counter is dropped?
If you pause between clicks, the counter may reset, press at a steady pace, and make sure you click on the version number, not the MIUI logo or model name.

Once activated successfully, go back to the main settings menu. Scroll down to the "Additional" section (sometimes called "Advanced Settings"), and a new item will appear, "Developers" -- now open to the user, and you can start fine-tuning.

Setting up USB-debugging and working with ADB

One of the main reasons why users activate a hidden menu is the need to use a hidden menu. USB-This protocol allows the computer to communicate with the phone at a low level without enabling this command function. ADB will not be executed and you will not be able to control the device via PC.

To activate, find the "Debugging by" switch in the developer menu USB" And you activate it. It will give you a warning about potential risks. Confirm the action. When you first connect to a new computer, you'll see a request on your smartphone screen to confirm the debugging with a specific debugging. RSA-Make sure to check the "Always Allow" box for this computer.

If you plan to use debugging often, it makes sense to include β€œDebugging over USB (security settings)” as well, which will allow you to execute commands that require increased rights, such as simulating clicks or changing system files. However, be careful: this gives apps and your computer full control over your phone.

adb devices

You can check the success of the connection through the command line on your computer. Enter the command shown above. If the list shows the serial number of your device with device status, then the connection is established correctly. Unauthorized status means that you need to confirm access on the smartphone screen.

πŸ’‘

Use the original cable or high-quality analogue with data support. Cheap "charging only" cables will not allow you to establish a connection for debugging, and you will waste time.

Interface optimization and hidden capabilities

Once you activate the developer menu, you have the ability to customize the visual part of the system. Android's standard settings limit the speed of animations, but the engineering menu removes those restrictions. This is the easiest way to make an old smartphone visually faster.

Find the section related to drawing. There you will see three parameters: "Window animation", "Ending animation" and "Duration of animation." By default, they are set to 1x. Change them to 0.5x or even 0x (to completely disable).

  • 🎨 Smallest width: allows you to change the density of pixels (DPI), making elements smaller and increasing the useful screen space.
  • πŸŒ™ Dark Mode: Forced Dark Mode to be enabled for all apps, even if they are not optimized.
  • ⚑ Acceleration GPU: rendering 2D-Charts that can help with old games.

Also worth noting is "Inactive Apps," which can limit the background activity of programs you rarely use, which helps save battery power and RAM, but don't overdo it: messengers and email clients can stop notifying if their activity is too limited.

⚠️ Attention: Change of the parameter "Least width" (DPI) If the buttons get too small, you can turn it back through the Recovery menu or reset it.

Frequent problems and ways to solve them

Despite the simplicity of the procedure, users sometimes encounter difficulties, such as the "Developers" item may disappear after a reboot if it was activated for only one session (although this is rare in modern versions of MIUI), most often the problem lies in an access rights conflict or shell failures.

If you can't turn it on USB-Check if the cable is connected, some firmware versions require an active connection to a PC or charger to activate this item, and make sure that the device is enabled file transfer, not just charging.

You see, there's a developer menu item, but all the settings inside are gray and not available, and this is often because you have "Stealth Protection" enabled or you have enterprise profiles activated, check if you have these profiles in your security settings, and try turning off and re-enable "Developers" again.

πŸ’‘

If the settings are reset by themselves, it is possible that an antivirus or optimizer application is installed in the system that blocks changes to system flags for security purposes.

Safety and return to the original state

The use of advanced features carries risks. Changing memory settings, background processes or drivers can lead to unstable work. If you notice frequent reboots or heating, the first thing you need to do is turn off the developer mode.

The developer's settings are automatically reset when you turn off the switch. All the animation values, process limits, and debugging flags that have been changed will return to factory values. Your phone will work the same way it did when you bought it (software).

Remember that unlocking the bootloader, which is also on this menu, is irreversible without flashing it. It erases all data and disrupts some of Google Pay's banking applications and services.

Can I get a virus through the developer mode?
The mode itself is not a virus. USB-When debugging and connecting the phone to an infected computer or a public charging station (juice jacking), attackers can gain full access to files. Always turn off debugging when it is not in use.
Is the developer mode reset when you update the firmware?
Usually, settings are saved when you update "over the air" (OTA). However, if you do a full reset (Wipe All Data) before the firmware, the developer mode will be turned off, and the activation procedure (7 clicks) will have to be repeated.
Does the inclusion of the regime affect the guarantee?
Just turning on the developer menu doesn't affect the warranty. It's a regular Android feature, and you can only lose the warranty if you start interfering with the system, like unlocking the bootloader, getting root rights, or installing modified firmware.
Why did the β€œDevelopers” item disappear after the reboot?
In some rare cases, older versions of MIUI may have done this. Solution: Re-run 7 taps on MIUI. Current versions of HyperOS and MIUI 12-14 fix this bug and save the settings permanently until manually disabled.
Is it safe to change the font scale in the developer menu?
Yes, it's safe. You can make the font smaller or bigger than the standard constraints, and the only risk is that the text can become unreadable, and then you have to reset the phone to the factory to get it back to normal.
