Why Xiaomi phone doesn’t turn off a call when someone calls – a full analysis of the causes and solutions

You click on the red phone to reset an incoming call to Xiaomi, but the call continues — the caller still hears the beeps, and the screen says, "Call active," and not only is the situation annoying, but it creates awkward moments: colleagues think you are ignoring them knowingly, and call center operators continue to impose services. In 80% of cases, the problem is solved in 5 minutes, but you need to pinpoint its source.

In this article, we will discuss all possible reasons why Xiaomi does not disable incoming calls – from banal failures. MIUI before hardware malfunctions of the communication module. → SIM-maps and mobile networks for hidden conflicts, why resetting to factory settings does not always help, and what to do if the problem appears after a firmware update. 4xx, which is manifested in the activated mode of energy saving.

1. MIUI software failures: why the interface "hangs" on the call screen

The most common reason is that the MIUI shell freezes when processing an incoming call, and it's because of:

• 📱 Overloaded system cache – temporary files of the phone application accumulate and block the correct completion of the call.
• 🔄 The latest updates are especially important for MIUI 14/15, where the phone module bugs were fixed with patches.
• 🎭 Design themes from third-party developers – they can redefine standard call screen animations.

How to check: Try to force the phone app to close through the multitasking menu (swipe up) during an active call. If the call is interrupted, it's the software that is to blame. If not, the problem is deeper.

Decision:

1. Clear the cache of the Phone application: Settings → Applications → Application Management → Phone → Storage → Clear the cache.
2. Turn off all third-party themes in Settings → Themes and go back to standard.
3. Check for updates in Settings → About Phone → System Update.

If the problem has occurred after the MIUI update, try to roll back to the previous version via Fastboot (the guide for power users).

2. Conflicts SIM-Cards: Double slot as a source of problem

On Xiaomi phones with two SIM-Cards (Redmi Note 12 Pro)+, POCO X5 Pro, Xiaomi 13T There is often a conflict of priorities; the system may forget which one it is. SIM Use it to reset the call, especially if:

• 📶 One of them SIM Deactivated but physically inserted into the slot.
• 🔄 Network Auto Select for both cards is included.
• 📵 One of them SIM It's working only on the 2G, second — 4G/5G.

Make sure both of you SIM active in Settings → SIM-map|

3. Hardware malfunctions: when the "iron" module is to blame

If software methods fail, the problem may lie in the physical components:

• 📞 Faulty communication module (especially after falls or moisture infestation).
• 🔌 Oxidized contacts SIM-Cards - phone 'doesn't see' call reset team.
• 🔋 Weak antenna signal – the smartphone can not correctly end the call session with the base station.

How to check:

1. Call from another phone to your Xiaomi and try to reset the challenge. If the problem recurs, it's a hardware glitch.
2. Light a flashlight on the tray of the SIM-card: if you see plaque or corrosion - contacts are oxidized.
3. Check the signal level in Settings → SIM-map → [choose SIM] → Signal level, if it's lower. -100 dBm, communications are unstable.

⚠️ Warning: If the phone falls or gets wet, do not try to disassemble it yourself, this can lead to a complete failure of the communication module.

4. Energy saving mode and background optimization

Xiaomi models with Snapdragon chipsets 4xx/6xx (Like Redmi. 10A, POCO M4 Pro) has a unique bug: when the power saving mode is activated, the system can ignore the call reset command to "save" the processor resources:

• 🔋 The call is not reset until you unlock the screen.
• 📵 After pressing the red tube, the screen goes out, but the call continues.
• ⚡ Call log shows call time at 00:00, although the caller heard the beeps.

1. Turn off the power saving mode in Settings → Battery → Energy saving mode.
2. Add the Phone app to optimisation exceptions: Settings → Battery → Battery Optimisation → All apps → Phone → Not Optimising
3. For MIUI 14+, disable Deep Optimization in Settings → Special Features → System Optimization.

💡

If the problem disappears after the power saving is turned off, the chipset bug confirms, in which case only a firmware update or a phone replacement (for older models) will help.

5. Failures in the operation of the communications operator

Sometimes it's not the phone that's the fault, it's the mobile phone operator.

• 📡 The problem arises with only one operator (for example, calls from MegaFon are not reset, and from Beeline - yes).
• 🔄 After the call is reset, the subscriber hears the message “Subscriber is temporarily unavailable».
• 📵 The call log displays the status "Not completed».

How to check:

1. Call your phone from another phone to your number – if the problem recurs, it’s the operator’s fault.
2. Check the status of services with the operator through USSD-commands: *100# - for Beeline *111# - for MTS *105# - for MegaFon *110# - for Tele2

Decision:

• 📞 Re-register online: type ##4636##, select Phone Information → Turn off the radio (wait 30 seconds) → Turn on the radio.
• 🔄 Reset network settings: Settings → SIM-map → [choose SIM] → Resetting network settings.
• 📡 Contact the operator support and request verification HLR-profile of your number.
