How to turn off the camera on the lock screen Xiaomi: the complete guide

Many Xiaomi and Redmi smartphone owners often experience a situation where a device in their pocket spontaneously activates a photo shoot, which is due to the standard quick activation feature that is built into the MIUI or HyperOS shell. By default, the system is configured so that double-pressing the volume button instantly triggers the Camera app, even if the screen is off and the phone is locked.

This option is useful when you need to capture a moment, but in everyday wear it becomes a source of problems. Random pictures fill the gallery, and the phone itself can discharge faster because of the module. It is also annoying when the characteristic shutter sound is heard in your pocket. In this article, we will discuss in detail how to deactivate this feature and what other security settings are worth checking.

The disabling process does not require superuser rights or third-party software installation. All the necessary switches are in the standard system settings menu. However, the location of the items may vary slightly depending on the version of Android and the manufacturer's shell modification. We will look at the current ways for modern firmware versions.

Reasons for spontaneous camera launch

The main reason for unwanted activation is precisely the function of “pocket mode” or “Quick start”. Xiaomi developers have implemented this mechanism for convenience, but users often forget about its existence after buying. The algorithm is simple: the system reads the signal from the accelerometer and proximity sensor, interpreting a series of clicks on physical buttons as a user command.

Sometimes the problem is not the software settings, but the mechanics. If the case is too tight or has defects, it can constantly press the keys, in which case the phone perceives this pressure as multiple clicks, and it is also worth checking the state of the volume button itself: sticking or oxidizing contacts can give false signals to the system.

Another factor is the operation of third-party applications.Some programs to clean up memory or optimize the battery may try to access the camera for scanning. QR-But 95 percent of the time, it's the double-click setup that's easy to turn off.

⚠️ Note: If the camera turns on on itself without clicking buttons, this may indicate the presence of malware. In this case, it is recommended to check the device with antivirus and analyze the list of installed applications.

Disconnection through system settings

The most reliable and correct way to remove automatic start is to use the built-in menu. The path to the desired switch can vary, but the logic remains the same for all smartphones of the brand. You need to find the section responsible for additional functions of buttons or gestures.

Please note that in new versions of HyperOS, some partition names may have changed, but the keywords “Loudness” and “Camera” remain unchanged.

To start, open the main menu and find the gear icon. Next, you'll need to go to the Additional Settings section. In some older firmware versions, this item may simply be called "Advanced Settings." Inside the list, look for the button management subsection.

Often, the item you want is hidden in the buttons and gestures or button management menu. If you don't see that section right away, try searching for the settings. Type the word "camera" or "volume" into the search box, and the system will highlight the switch.

When you find Camera Start (or Quick Launch), you'll see an active switchboard that responds to a double-pressing of the volume button, put the switch inactive, and from there on, the double-click will be ignored by the system when the screen is off.

Setup in the Camera app

Sometimes the settings are duplicated or take priority in the shooting app itself. The MIUI Camera shell has its own configuration menu that can override system settings. If disabling through the phone settings didn't help, it's worth checking the app's internal settings.

Open the Camera app and click on the three bars in the upper right corner to enter the menu. Select the gear icon to go to the settings. Scroll down to the "Additional" or "General" section.

You can have a "Mode in your pocket" or "Fast start" option here, make sure that all the options associated with managing the volume buttons are turned off, and you can also set up a photo and video save format in this section, which will help save space if random pictures are taken.

It is worth noting that after updating the Camera app through the GetApps store or Google Play, the settings can be reset to factory, so if the problem returned after the software update, it is worth checking again.

Use of Do Not Disturb and Blocking

An alternative way to prevent random action is to use Do Not Disturb mode. Although it does not directly disable the start button, it limits background activity and notifications, which indirectly affects the system's behavior when locked.

You can set this mode to automatically turn on on on a schedule or geolocation. For example, when you are at home or sleeping, the phone will behave more calmly. To activate, go to Settings → Sound and vibration → Do not disturb.

There's also a Pocket Mode feature in the Special Options section, designed to prevent random screen clicks, but sometimes it affects button signal processing. Activate it along the Settings path → Additional Settings → Special Features → Pocket Mode.

⚠️ Warning: Enabling Do Not Disturb mode may result in missing important calls or messages unless exceptions are configured. carefully check the list of permitted contacts before activating.

For maximum protection, you can use third-party locker applications that require unlocking even to run system functions, but this can slow down the device and increase power consumption.

Solving button sticking problems

If the software shutdown doesn't work and the camera keeps turning on, the problem may be physical, and the dirt, pile, or moisture that gets under the volume button creates a permanent closure of the contacts, and the system perceives this as an endless press.

Try to clean the area around the buttons gently. Use a soft toothbrush or compressed air. Do not use cleaning fluids as they can damage the internal components of the smartphone. Light tapping of the phone against the palm can also help to knock out dust.

You can check the status of the button using the engineering menu. Enter the code ##64663## in the Calls app (or find Testing in the settings). Select a button test and check if the volume button is stuck when pressed.

💡

If the volume button is physically damaged, temporarily reassign its functions through macro applications to avoid accidental starts until repair is possible.

If you have a mechanical failure, the software will be powerless, you'll need to replace the button plume or the entire body in the service center, and ignoring the problem can lead to oxidation of the board.

Resetting and software update

If none of the methods worked, there may have been a software failure. Updating the firmware to the latest available version often fixes bugs associated with handling interrupts from physical buttons. Check for updates in About Phone → MIUI.

In extreme cases, you can reset all settings. This will return the phone to factory status by deleting all user data. Before that, be sure to back up contacts and files. Reset is done through Settings → About Phone → Reset.

After reset, don't restore the backup of your system settings right away, check if the camera is running properly on a clean system, and if the problem is gone, it's a setting conflict or a third-party application.
