Hidden shooting on Xiaomi: how to shoot videos and photos unnoticed by others

Xiaomi smartphones have long since ceased to be just a means of communication, they have become versatile tools that can solve hundreds of tasks, including those that the manufacturer prefers not to mention in official instructions. One of these “gray areas” is hidden photography: whether it is fixing an important conversation, documenting illegal actions or simply the desire to capture a moment without attracting attention. Unlike specialized spy gadgets, Xiaomi smartphone allows you to organize a hidden recording at minimal cost – the main thing is to know the right settings and bypass the limitations of the system.

It’s important to understand that covert photography is at the intersection of technical capabilities and legal frameworks. In most countries, recording video or audio without the consent of participants is considered a violation of the law if it is conducted in places where a person has a right to privacy (for example, in toilets, hotel rooms or in private territory). However, there are legal scenarios: recording street incidents, evidence in court or filming in public places where there is no expectation of confidentiality. This article does not call for breaking the law, but only describes the technical aspects of how Xiaomi’s camera works in non-standard modes.

We have analyzed the capabilities of more than 20 models of smartphones Xiaomi, Redmi and POCO (From Redmi Note 8 Pro to Xiaomi 13 Ultra and revealed 7 working methods of hidden shooting – from built-in features MIUI We'll also look at how to mask the process of shooting as harmless actions (for example, listening to music) and what applications will help automate the process. If you’re looking for a way to record video so that the screen stays off and the indicators don’t reveal your actions, this is the guide for you.

1. Black Screen Mode: How to Shoot With Display Off

The most reliable way to shoot hidden on Xiaomi is to use Black Screen (or Screen Off Recording) mode, which is available on most devices with a high-end camera. MIUI 12 and newer, but by default hidden from the user, its activation allows you to record a video or take a photo when the smartphone screen is off, and the shooting process itself is not accompanied by shutter sounds or vibrations.

To activate the regime:

• 📱 Open the Camera app and go to Settings → Additionally.
• 🔍 Scroll down to Black Screen Mode (if not, see next paragraph).
• 🔄 Activate the switch and confirm permission to use the camera in the background.
• 📹 Now, when shooting starts, the screen will go out in 2 seconds, but the recording will continue.

If the camera settings don't have a Black Screen, you can unlock it through the engineering menu.

1. Open the phone app and enter the code: ##4636##
2. Go to the section Testing equipment → Camera.
3. Find the parameter. camera.screen_off_recording and set the value 1.
4. Reboot your smartphone.

⚠️ Attention: On models POCO F3, Redmi Note 10 Pro and the newer engineering menu may block access to certain options.In this case, use alternative methods (see section 3).

The advantage of this is that it's completely free of visual signatures, but there are also disadvantages.

• 🔋 Increased battery consumption (up to 15% per hour when recording) 4K).
• 📱 It does not work on some custom firmware (for example, LineageOS).
• 🚫 Video is not saved if you close the Camera application through the Task Manager.

To quickly turn on the black screen, add the Camera shortcut to the lock screen. Double-pressing the power button will start recording even without unlocking the phone (works on the phone). MIUI 13+).

2. Shooting through gestures and voice commands

If you don’t want to mess around with settings, but you need to quickly take a photo or video without attracting attention, use gestures or voice commands. This method is suitable for models with support for Google Assistant or Xiao brand assistant. AI (Available in China and Global Firmware with Regional Patch).

Methods of activating hidden photography:

• 🤏 Tickle gesture: Twice compress the screen (as in zooming) in any application – the camera will open and recording will begin (configured in Settings) → Special facilities → Gestures).
• 🗣️ Voice command: Say “OK, Google, take a photo” or “Hey Xiao” AI, Record the video" (requires a preset voice assistant).
• 🔑 Lock button: Press and hold the power button + increase volume for 3 seconds - the camera will start in the background (works on the camera) MIUI 14).

The main advantage of the method is speed, for example, the "pinch" gesture works even when the phone is in your pocket (if the screen is on).

• 🔊 Voice commands can attract attention when the surroundings are quiet.
• 📸 Gestures do not work on all models (for example, on Redmi). 9A They're gone).
• 📱 Video saved to standard gallery, which could raise suspicions when checking phone.

3. Apps for masking shooting for other actions

If you don't like Xiaomi's built-in features, you can use third-party apps that mask the camera as other programs, such as a calculator, player or browser, which not only hide the process of shooting, but also encrypt recorded files so that they can not be found when you surface-check the phone.

Top.-3 Proven applications for Xiaomi:

6. How to hide files after shooting: encryption and masking

Even if you've managed to make a video invisibly, you still have to hide it from prying eyes. MIUI There are built-in tools to hide files, but they don't provide strong protection:

Level 1: Embedded facilities MIUI

• 📁 Move files to the.nomedia folder (it doesn't appear in the gallery).
• 🔒 Use the Private Album in the Gallery app (password protected).
• 🗃️ Archive files in ZIP password-wise (via Files) → Archivator).

Level 2: Third-party annexes

• 🔐 Andrognito – creates a safe with encryption AES-256. Files are deleted after 5 failed attempts to enter a password.
• 📂 Hide It Pro masks the folder with files as an audio player, and to access it, you need to enter a password in the search box.
• 🌐 Cryptomator – encrypts files and uploads them to the cloud (like Google Drive) in encrypted form.

Level 3: Systemic Hiding (root required)

• 🛠️ Move files to the system folder /data/local/tmp/ — It's not scanned by the gallery.
• 🔧 Change the file extension (for example, with.mp4 on.dat).
• 📥 Use Termux for encryption: pkg install openssl openssl enc -aes-256-cbc -salt -in video.mp4 -out video.enc -pass pass: your password

⚠️ Note: When using Andrognito or Hide It Pro, disable autosynchronization with Mi Cloud – otherwise files can get to the cloud in an unencrypted form.
