When a smartphone makes calls on its own, it can be taken by surprise at the most inopportune moment. Auto dialing on Xiaomi Redmi often causes embarrassing moments or, worse, leads to unforeseen communication costs, and device owners face this, not realizing what exactly in the system causes the device to react to external or internal events.
The reasons for this behavior can range from simple randomness to complex software conflicts. MIUI, being a deeply modified shell, has many hidden features that can be activated by mistake. Sometimes the problem lies in the physical state of the screen or accessories, not in the software.
In this article, we will go into detail about all possible scenarios and how to fix them, learn how to check the settings, eliminate hardware malfunctions and regain control of your device, and a systematic approach will solve the problem even in advanced cases.
Reasons for spontaneous calls on Xiaomi
Before you start to act, you need to understand the nature of the problem. Auto dialing rarely happens for nothing; it always has a trigger. Most often it's a function that was turned on long ago and forgotten, or a sensor malfunction.
One common reason is a pocket kit, which is that a smartphone in a cramped pocket or bag responds to pressure and body heat, and MIUI algorithms can interpret these touches as a command to call the last contact or emergency service.
- 📱 Activated function "Pocket mode" with increased sensitivity.
- ⚡ Software failure in the operation of the communication module or application "Phone".
- 🔌 Poor-quality charger that creates interference in the operation of the touch screen.
- 🖐 Physical damage to the display or lack of protective glass.
Also consider the impact of third-party applications: installed widgets or optimization programs may have permission to make calls, background processes sometimes behave incorrectly after a system update.
⚠️ Warning: If the phone makes calls while the screen is off and the device is lying on the table, the problem may be more serious.This could indicate malware trying to contact the paid numbers.
Checking the settings of pocket mode
The first thing you need to do is check the settings that are responsible for the screen operation in the closed state. In the shell of the Xiaomi HyperOS and older versions of MIUI, this is a special mode, its purpose is to prevent accidental pressing, but when it crashes, it works the opposite way.
To access the settings, go to Settings → Lock screen. You should find the item associated with the mode in your pocket. If it is on, try turning it off and see if the problem disappears. Sometimes the reverse action of turning on the maximum protection mode helps.
In some cases, settings can be hidden or moved to the special features menu. Check the Settings path → Additional settings → Special features. There may also be switches that affect the response of the touchscreen.
- 🔍 Find the "Block screen" section in the main settings.
- 🚫 Turn off the option "Mode in your pocket" for testing.
- 🛡 Enable "Advertent Press Protection" if this option is available separately.
- 🔄 Restart the device after changing the parameters.
It is important to understand that disabling protection can lead to other random actions if you carry a phone without a case.The balance of settings depends on your gadget usage habits.
💡
Use a magnetic case with smart lock function, which physically prevents touching the screen when the phone is in the bag.
Settings of the application "Phone" and MIUI Dialer
The standard call app has its own settings that can trigger an auto dial, such as quick dial or re-call, and MIUI Dialer often turns these settings on by default.
Open the Phone app and click on the three dots or gear in the corner of the screen. Select Settings. Here you should be interested in the section related to incoming calls or responses. Make sure that the response function is not activated when you bring it to your ear if it is not working properly.
Pay special attention to call history. Sometimes autocalls for missed calls are enabled in the operator's settings or through third-party utilities, and check if you have a program installed to automatically respond to messages or calls.
| Parameter | Recommended value | Impact on autodiplom |
|---|---|---|
| Quick set. | Off. | High (preventive pressing) |
| Answer by submitting | Off. | Medium (false positives) |
| Vibration on touch | As you wish. | Low (tactile connection only) |
| Recording of conversations | Automobile | Low (does not affect the set) |
If you use a third-party call, like a Google call, you need to look inside the app itself, and the system conflicts between the standard call and the one you have installed can cause chaotic behavior.
☑️ Checking the call settings
Diagnosis of touch screen and hardware problems
If the software settings are in order, the reason may be "hardware." The multitouch of modern screens is very sensitive. Cracks, severe scuffing or moisture under the glass can create "phantom" presses.
Diagnose the screen. Xiaomi devices have built-in engineering menus. Dial ##6484## in the dialer. This will open the CIT (Customer Information Test) menu. Select the Touchpanel test and check if there are any spontaneous marks on the screen without you.
A common cause of chaotic action is an unoriginal charger: Cheap power units don't have proper current filtration, which creates electrical tips; the touchscreen starts to "go crazy" while charging, dialing numbers or opening applications.
- 🔌 Try charging your phone with another cable and power supply.
- 💧 Make sure the screen is dry and clean of fat.
- 🛠 Remove the protective glass if it is damaged or curved.
- 🌡 Check your phone for overheating that affects sensor performance.
If you see in the engineering menu that the dots on the screen appear on their own, you'll probably need to replace the display module. You can't fix this with software.
⚠️ Warning: Don't ignore battery bloating. If the battery is bloated, it can push the display plume from the inside, causing false positives to the touchscreen.
Reset network settings and call parameters
Sometimes the problem lies in accumulated errors of network settings. resetting network settings will not delete your personal data (photos, contacts), but will return the settings. SIM-This often helps if the auto dial is associated with a conflict of operator settings.
Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm action. Once rebooted, the phone will re-register on the operator’s network, which can eliminate the call routing error.
Also worth checking is that carrier-level call forwarding is enabled. dial *#21# to find out the redirect status. If it's active without your knowledge, turn it off with ##002#.
Hidden. USSD-diagnostics
In some cases, cleaning the cache of the Phone app helps. Go to Settings → Apps → All apps → Phone → Memory. Press the Clean button and select Clear cache. This will delete temporary files that may have been corrupted.
Resolving conflicts of third-party applications
Third-party launchers, sign-up themes, and call utilities can take control of your phone. If a problem occurs after you install a new app, try removing it. Pay special attention to programs that require permission to access contacts and calls.
Safe Mode is a great way to check if third-party software is to blame. Press the power button, and when the turn off menu appears, press and hold the "Stop" (or "Reboot", depending on the version of MIUI) option, and a request to enter Safe Mode will appear.
This mode only runs system applications, and if the auto dialing has stopped in safe mode, then the problem is exactly in the installed software, and remove the applications one by one, starting with the last ones installed, to find the culprit.
- 📲 Check out the list of recently installed apps.
- 🚫 Remove programs to automate calls or record conversations.
- 🎨 Turn the design theme to standard.
- 🧹 Clean the system cache through the built-in optimizer.
Remember that some Trojan viruses disguise themselves as system processes. Antivirus verification with the built-in security scanner Xiaomi will not be superfluous.
💡
If the problem disappears in Safe Mode, look for the cause in third-party apps, not the system.
Radical measures: complete reset (Hard Reset)
If none of the above methods work, the last option is a full factory reset, which will remove all data from your phone, so be sure to back up important files and contacts on your Mi Cloud or computer.
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take a few minutes. Once turned on, the phone will be like new, without user data or settings.
If the problem persists even after the reset, it is 99% indicative of a hardware malfunction, in which case you should contact a service center for the diagnosis of the motherboard or plumes.
