Xiaomi Redmi 9 Pro smartphone hides powerful tools under the hood to fine-tune the system, but by default they are not available to the average user. Developer mode is a โsecret doorโ to advanced Android settings, where you can activate debugging over USB, change the interface animation or even overclock the performance of the GPU. However, improper use of these features can lead to malfunctions in the device.
In this article, you will find a step-by-step instruction with visual clues on how to turn on the developer mode on Redmi. 9 Pro (models) M2007J17C/M2007J17G), We'll also learn which settings to change first and which to avoid, and we'll understand why Xiaomi hides these options from users and how to use them safely to optimize the smartphone experience.
Why do I need a developer mode on Xiaomi Redmi 9 Pro?
Developer Mode is not just a โgeek thingโ, but a full-fledged tool for:
- ๐ง Debugging applications through ADB (Android Debug Bridge โ indispensable for software testing or system recovery after crashes.
- โก Speed up the interface by disabling animations or forcing it to turn on GPU-rendering.
- ๐ฑ Unlock the bootloader before installing custom firmware or obtaining root rights.
- ๐ Background Process Control: Limiting Active Applications to Save Battery.
For example, if your Redmi 9 Pro started to โslow downโ after updating to MIUI 14, In developer mode, you can manually limit the number of background processes or disable unnecessary services. force_gpu_rendering on weak devices can lead to overheating and accelerated battery discharge.
The developer mode is also required for:
- ๐ฅ๏ธ Connecting a smartphone to Android Studio for app development.
- ๐ Bypassing certain restrictions MIUI (for example, locking the installation APK source).
- ๐ก Network parameters testing (change of network type, inclusion of radio module log).
Preparation: What to do before turning on the developer mode
Before you activate hidden settings, follow 3 mandatory steps:
- Check out MIUI. On Redmi 9 Pro, the path to developer mode may vary depending on the shell version. Go to Settings โ About Phone โ MIUI Version. If you have MIUI 12.5 and newer, use the instructions below. Older versions (MIUI 11) may require a different algorithm.
- Charge the battery by at least 50%. Some operations (for example, unlocking the bootloader) require stable power supply.
- Back up important data. While it is safe to turn on the developer mode, subsequent changes to the settings can cause failures.
Also note that some firmware (especially global versions of MIUI) may display a โunsafe setupโ notification after the developer mode is activated.
Check the version of MIUI in Settings โ About the phone
Charge the battery to 50% or more
Create a backup of contacts and files
Make sure that the phone has enough free memory (minimum 1 GB)

Step-by-step: how to turn on the developer mode on Redmi 9 Pro
The activation algorithm is the same for all Xiaomi Android smartphones, but we will analyze it in detail with regard to the Redmi 9 Pro, taking into account the features of MIUI.
Step 1: Open your phone settings
Run the Settings app (the gear icon on the home screen or in the app menu). If you have One-Hand Mode enabled, swipe down the screen to see all menu items.
Step 2: Go to the About Phone section
Scroll down the settings list and select About Phone (usually at the bottom). On some firmware, it may be called About Device or Phone Information.
Step 3: Find the MIUI version
In the window that opens, find the MIUI version line. Press it 7 times in a row at intervals of no more than 1 second. After the third click, notifications about the remaining steps will appear on the screen (for example, โ4 clicks remainingโ).
If you did everything right, a message will appear:
You're a developer!Step 4: Return to the main settings menu
Press the back button (arrow at the top of the screen or swipe gesture on the right) Now a new option will appear in the main settings list - Additional (or Advanced Settings), and inside it - For developers.
If there is no item, try:
- ๐ Reboot the phone.
- ๐ Update MIUI Up to the latest version (sometimes interface bugs hide a new partition).
- ๐ฑ Check if the item is hidden in the "Special features" (rarely, but it happens on custom firmware).
What if the message โYou are a developerโ does not appear?
Where to find the developer settings after activation
Once the developer mode is successfully enabled, the new partition can be hidden in different places depending on the MIUI version.

What developer settings can be safely changed on Redmi 9 Pro
Not all options in developer mode are equally useful. We selected the 5 most secure and useful options that will not harm the system:
- โก Debugging by USB (Debugging USB) โ It is necessary to connect to the PC through ADB Or Fastboot. Turn on only when necessary and turn off after use to avoid data leaks.
- ๐ฎ Enforcement of use GPU (Forced rendering on GPU) โ It speeds up the animation of the interface, but it can increase the battery load.
- โฑ๏ธ Disabling animations (Windows animation scale, transition animation scale) - set the value 0.5x or off to speed up work MIUI.
- ๐ Background Process Limits โ Choose a Maximum 2 process to save battery (but some applications may close more often).
- ๐ถ Enabling a radio module log (Make a radio module log) โ useful for diagnosing network problems (e.g., if not catching) 4G).
Hereโs what you should not touch without an urgent need:
- ๐ซ Screen inactivity โ changing the timeout can lead to a quick discharge.
- ๐ซ Turn off the absolute volume level - will disturb the sound balance in the headphones.
- ๐ซ Imitating additional screens โ can break multi-window mode.
โ ๏ธ Attention: Change of the OEM-unlock parameter (OEM Unlocking) without further unlocking the bootloader can result in the Mi Account being blocked when resetting. Xiaomi associates this setting with anti-theft protection.
