You miss important calls because Xiaomi's locked screen doesn't display caller information? This problem is common on Redmi, POCO and Mi smartphones regardless of the MIUI version. In some cases, the screen just flashes or shows a standard screensaver without a contact name and number, and sometimes the call doesn't wake up the display at all. Consider all the possible causes - from banal settings to system failures - and give unique solutions that you won't find in standard Xiaomi instructions.
The problem may be related to:
- π Screen lock settings (Hide notifications mode enabled")
- π± Mistakes. MIUI after updating or resetting
- π οΈ Application conflict (especially launchers and optimizers)
- π Energy saving that blocks the phoneβs background activity
- π Work failures SIM-map
In this article, 7 proven ways to return incoming calls to a locked screen, including hidden MIUI settings that are not documented in the official help, and how to prevent this from happening.
1. Check the basic screen lock settings
The first thing to do is make sure that system settings donβt block notifications from appearing on a locked screen.The MIUI has a separate section to manage notifications when blocked, which often gets knocked down after updates.
Open Settings β Screen Lock β Notifications on the locked screen and check:
- π Is the "Show Notifications" slider enabled (should be active)
- π In the list of applications, find the βPhoneβ and make sure that it is allowed to display.
- π If the mode "Hide the contents of notifications" is enabled, turn it off - it can hide the caller's number.
Some models (e.g. Redmi Note 12 Pro+) have an optional Settings β Apps β App Management β Phone β Notifications β Show on a locked screen. If it is disabled, calls will not be displayed.

On smartphones with AMOLED-screens (e.g. Xiaomi 13 Ultra) check settings β Display. β Always-on Display: If the Watch Only mode is enabled, it can suppress other notifications, including calls.
Resetting the settings of the "Phone" application
If the basic settings didn't work, the problem could be the phone app itself, and MIUI has a hidden feature to reset its configuration without deleting data.
Follow the following steps:
- Go to Settings β Applications β Application Management
- Find the phone app (may be called "Calls")
- Slip on "Storage and Cache" β "Clean Cache"
- Go back and select Settings Reset (does not delete your call history!)
- Reset the device
After the reboot, check if incoming calls are displayed. If the problem persists, proceed to the next method.

3. Checking permission to display over other windows
MIUI aggressively manages background processes, and sometimes the Phone app loses resolution to display over lock, especially after installing custom launchers (like Nova Launcher) or memory optimizers.
To check and correct:
- Open Settings β Applications β Application Management β Phone
- Select "Other Permits"
- Find the item "Show over other windows" and turn it on
- Also turn on "Autostart" and "Background Activity"
If these are not available, try an alternative route:
- Press the icon of the phone application on the main screen
- Select "Application Information"
- Slip on "Permissions" β "Additional"
- Activate all available permissions related to notifications

4. Bypassing energy saving restrictions
Battery Optimization in MIUI often blocks background processes, including incoming call processing, which can manifest as no vibration, sound, or display on the screen when locked.
To correct:
- Go to Settings β Battery and Performance β Battery Consumption Management
- Select "Applications Selection"
- Find the phone in the list and set it to "No restrictions" mode.
- Also check the Sleepy State section and make sure that Phone is not on the list of restricted apps.
Some devices (e.g., POCO F4 GT) have an optional setting for Settings β Battery β Battery Settings β Performance Mode. Select Balanced or Performance, as Power Saving Mode can block call notifications.
π‘
If the battery settings change, the problem returned after a few days, the reason may be automatic MIUI optimization. To avoid this, add the Phone app to the memory cleanup exceptions (Settings β Applications β Memory Cleanup β Exceptions).
Verification of work SIM-maps and communication module
If the calls are not displayed for one person only SIM-cards (on dual-symbol devices), the problem may be in the settings of the network or the card itself, and this is also true if you have previously changed the operator or updated the firmware.
Do the diagnostics:
- πΆ Switch the slot. SIM-If you have a two-sim phone, if the calls are displayed, the problem is: SIM-card.
- π Reset network settings: Settings β SIM-maps and mobile networks β Resetting network settings
- π± Check the network mode: sometimes forced selection 4G (without 3G/2G) It can cause incoming calls to crash. Try installing the car.
- π§ Update your operator profile: some operators (such as Tele2 or Iota) require a manual configuration update. USSD-query ##4636##, select "Phone Information" and tap "Update profile".
If after these actions the calls are still not displayed, try temporarily disabling the second. SIM-If you have a card, check the main card, and sometimes a conflict between two cards leads to a call processing failure.
π‘
On eSIM devices (such as Xiaomi 13 Lite), check if the virtual system is in conflict. SIM Try to turn off the eSIM during the test: Settings β SIM-map β ESIM management β Shut down.
6.Recovery of system files through Safe Mode
If the problem occurred after installing third-party applications (especially launchers, antiviruses or optimizers), they could damage the system files responsible for handling calls.
How to run Safe Mode on Xiaomi:
- Turn off the device.
- Press the power button before the MI logo appears.
- Once the logo appears, press and hold the volume button until the download is complete.
- In the lower left corner of the screen will appear the inscription "Safe mode".
In this mode:
- π Check if incoming calls are displayed on the locked screen.
- π± If the problem has gone away, uninstall the recently installed apps (especially those that have access to notifications or phone features).
- π If the problem persists, reset the network settings (Settings) β System system β Resetting settings β Resetting network settings).
To exit Safe Mode, simply restart the device.

7. Hidden MIUI settings for displaying calls
V MIUI There are undocumented parameters that can affect the display of incoming calls, and you can change them through the menu of engineering settings or ADB-team.
Method 1: Engineering menu (for experienced users)
- Open the Phone app and enter the code: ##4636###
- Go to the section "Phone Information"
- Scroll down to the "Network Settings" block.
- Find the option "Incoming call notification" and set the value "Enabled"
- Also check the βCall Waiting Notificationβ option β it should be enabled.
Method 2: ADB-teams (requires PC)
If you have access to a computer, you can execute the following commands:
adb shell settings put global incoming_call_notification 1
adb shell settings put global heads_up_notification_enabled 1
adb shell settings put global lock_screen_show_notifications 1These commands compulsorily include:
- π Display notifications about incoming calls
- π Pop-up notifications (heads-up)
- π Display notifications on a locked screen
π‘
If, after application, ADB-commands reset after restart, this indicates damage to the system partition, in which case only flashing through Fastboot (without data loss, if you choose the option save userdata) will help).
