How to record a screen on Xiaomi Redmi Note 9 Pro: a step-by-step guide

The Xiaomi Redmi Note 9 Pro remains a popular smartphone even years after its release, but many users still don’t know how to make the most of its features. One of the most popular features is screen recording, which is useful for creating guides, streams, saving gameplay or showing errors in the operation of applications. Unfortunately, MIUI does not have an obvious “Screen Record” button in fast settings, like competitors, which causes confusion.

In this article, we’ll take a look at all the screen recording options available on the Redmi Note 9 Pro, from hidden MIUI features to third-party apps with advanced settings, learn how to record video with internal sound, no watermarks, and high resolution, even if your smartphone isn’t rooted, and uncover a secret method of activating embedded recording through an engineering menu that isn’t written about in the official instructions.

1. Built-in screen recording function in MIUI: where to look and how to turn on

Check question: have you ever noticed a video camera icon in the notification panel? If not, you're not alone. Xiaomi has hidden the screen recording so deep that even experienced users miss it. On the Redmi Note 9 Pro with MIUI 12/13/14, this feature is available by default, but requires pre-tuning.

To activate it:

• 📱 Open the Settings. → Special facilities → Quick setups
• 🔍 Scroll down and find the "Screen Recorder" item (may be called "Screen Recorder")
• 🔄 Drag this element into the active Quick Settings Panel (top of the screen)
• 🎥 Now, when swipeing down, the recording button will appear twice.

The first run may raise questions: the system will ask permissions to record sound and display on top of other windows. Be sure to confirm both requests, otherwise the recording will be soundless or error-free. Important: the built-in MIUI feature only records system sounds (not a microphone!) and adds a watermark with the Xiaomi logo.

💡

If the write button disappeared after the MIUI update, reset the notification bar settings: Settings → Notifications → Additional → Reset the panel settings

2. Advanced built-in recording settings: resolution, FPS and sound

Few people know, but the built-in MIUI recorder supports quality settings — but access to them is not obvious. After the first start of the record, swipe down the notification bar and tap on the notification "Screen recording is coming." A minibar will open with three key options:

Critical feature: when you select 1080p@60FPS, the recording is automatically limited to 3 minutes - this is protection against overheating of the Snapdragon 720G processor. To remove the restriction, you will have to use third-party applications (see section 4).

3. Secret method: recording through engineering menu (no ROOT)

This method only works on the Redmi Note 9 Pro with MIUI 12.0.1–12.5.7 and allows you to bypass the limitations of a standard recorder.

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Phone Information
3. Tap 5 times on the item "Version" MIUI" (A message will appear: You have become a developer")
4. Go back to the basic settings, open More → For developers
5. Find the option “Enable Screen Recording (MTK)” and activate it

After the reboot, a new recording button will appear in the notification bar with advanced options: microphone support, selecting a bitrate of up to 20 Mbps and the ability to record in the background. Warning: this method can cause unstable camera performance while recording simultaneously - test before important sessions.

4. Top.-3 Third-party applications for recording with Redmi Note 9 Pro

The built-in MIUI tools are limited in functionality, so it’s worth considering alternatives for professional recording. We tested 15 apps from Google Play and selected the three best ones for the Redmi Note 9 Pro:

• 🎮 AZ Screen Recorder is the best choice for gamers (supports) 1080p@60FPS time-free, there is a built-in editor and streaming on YouTube)
• 🎤 DU Recorder is the only application with a normal microphone on the MIUI (But adds a watermark in the free version)
• 📱 Mobizen – optimized for social networks (automatic video clipping for the format) TikTok/Reels)

An important caveat: on the Redmi Note 9 Pro with MIUI 13+, some apps may not record sound due to Xiaomi's security policy.

1. Install Shizuku from Google Play
2. Connect to your PC and execute the command: adb shell sh /sdcard/android/shizuku/start.sh
3. In the settings of the recorder application, select the method of recording audio through the AudioRecord API.

✅ Allow display over other windows

✅ Provide access to the storage facility

✅ Enable "Sound capture" in the application settings

✅ Disable battery optimization for recorder

✅ Check the vacant space (1 minute 1080p@60FPS = ~300 MB)-->

5. Gameplay recording: how to avoid lags and jerks

The Redmi Note 9 Pro on the Snapdragon 720G is capable of recording gameplay at 1080p, but only with the right settings. The main problem is overheating and trottling, which lead to a drop in the FPS. Here is how to minimize the risks:

• ❄️ Start recording only when the battery charge is above 50% (or connect charging)
• 🔧 In the developer settings (Settings) → The phone. → Version. MIUI → 7 taps) disable: "Background Process Limitation" (set "Standard Limit") "Optimization" MIUI" record-app
• 🎮 For heavy games (Call of Duty, Genshin Impact) lower your graphics settings to "Medium/Balance"

We test the performance using the example of PUBG Mobile:

Key conclusion: for smooth gameplay recording, the optimal mode is 720p@60FPS or 1080p@30FPS with cooling on (use a cooling stand or fan).

💡

Redmi Note 9 Pro cannot simultaneously record the screen and stream the game on Twitch/YouTube through the same app, which causes critical overheating.

6. Problem Solving: No sound, lags, no video saved

Even with the right settings, screen recording on Xiaomi can malfunction.-5 Errors and solutions specific to Redmi Note 9 Pro:

⚠️ Note: If the video is not saved after recording, check the permissions for the com.miui.screenrecorder app via ADB: adb shell pm grant com.miui.screenrecorder android.permission.WRITE_EXTERNAL_STORAGE Without this command, files will be created in the cache and automatically deleted.

• 🔇 No sound in the recording: For built-in recorder: MIUI It blocks the capture of sound in some regions. Solution -- change region to India in Settings. → Additionally. → Region For Third Party Apps: Install Samsung’s SoundAssistant (powered by Xiaomi!) and turn on “Separate App Sound"
• 🐢 Recording slows down: Turn off "Windows Animation" in the developer settings (set the animation scale on the 0.5x) Use the recording format MPEG4 instead MKV (lesser load CPU)

Another common problem is the black screen in DRM-protected application records (Netflix, Disney+, banking apps), a restriction on Android that cannot be circumvented without root rights, the alternative being to record games via Google Play (if the app is supported) or use a second device to shoot the screen.

7 Where records are stored and how to edit them

By default, all videos are saved in /storage/emulated/0/Movies/ScreenRecords/

or

/storage/emulated/0/DCIM/Screenshots/

For quick access:

1. Open the Gallery → Albums → Screen recordings
2. Or use a file manager (such as Mi File Manager) and follow the path above.

For basic editing (shortcutting, adding text) suitable:

• 🎬 CapCut is the best free editor for social networks (cutting at 9:16, transition effects)
• 📹 KineMaster – for multitrack editing (you can overlay the voice over the recording)
• 🖼️ InShot – if you need to quickly add music to the library

⚠️ Attention: Video with permission 1080p The above may not open in the standard Xiaomi Gallery due to decoding restrictions. MX Player or VLC viewable.
