You've noticed that your Xiaomi smartphone (be it Redmi Note 12, POCO X5 or Mi 11) has started flashing notifications — and you don't know what that means? — this little LED can transmit a whole range of messages, from trivial notifications about missed calls to serious hardware failures. In 80% of cases, the problem is solved software, but sometimes the blinking signals critical malfunctions that require the intervention of the service center.

In this article, we will look at all the possible causes of flashing the indicator on Xiaomi phones, including rare cases that are not written about in the standard instructions. LED And what to do if the light flashes without stopping even after resetting. AMOLED-screens where LED is often integrated into the display, and its diagnosis has nuances.

For convenience, we have collected data on current MIUI 14/15 firmware and the latest models from 2023-2026, but the instructions will also be suitable for older devices (for example, Redmi 9 or Mi A3). If after reading the article the problem remains, at the end you will find a checklist for quick diagnosis before visiting the service.

1. Standard causes of indicator blinking (not critical)

In most cases, the flashing indicator on Xiaomi is just a visual alert of events.

• 📞 Missed calls – usually flashing red at intervals of 1-2 seconds.
• 📧 Unread. SMS/messages - blue or green (depending on the model).
• 🔋 Low battery charge: orange/yellow (blinks more often at levels below 15%).
• 🔔 Active notifications from apps (WhatsApp, Telegram, mail) – color depends on settings.

On models with Always-On Display (e.g. Xiaomi 13 Pro or POCO F5), the indicator can duplicate information from the screen, but sometimes flashes separately - this is a feature of the firmware.

1. Go to Settings → Notifications and Status bar → Notification indicator.
2. Turn off the LED light switch or adjust colors for specific applications.
3. For MIUI 15: Add system applications (e.g. Phone or Messages) to the exceptions so that they don’t duplicate blinking.

Important! On some models (like the Redmi 10), the indicator flashes white when connected to charging — this is normal and means that the device is charging normally. If the color suddenly changed to red, check the cable or adapter.

2. Programmatic failures: when the indicator flashes "for no reason"

If the indicator flashes without notifications, and there are no new messages in the status bar, the problem is most likely in the software.

• 🤖 Hanging background app (often messengers or games are to blame).
• 🔄 Failed update MIUI (Especially after the "dirty" installation on top of the old version).
• 📱 Design themes conflict (for example, after installing a custom theme from the Mi Theme Store).
• 🔌 Failure of the notification service (com.android.systemui process).

For diagnosis, follow the following steps:

Check the notification log (Settings → Notifications → Notification log)

Restart your phone in Safe Mode (press the power button → “Safe Mode”)

Turn off battery saving for system applications (Settings → Battery → Charge Savings → Applications)

Reset the notification settings (Settings) → Annexes → Application management → ⋮ → Reset the notification settings)-->

If the problem has disappeared in Safe Mode, it is the third-party app that is to blame. Uninstall recently installed programs or reset to factory settings (don’t forget to make a backup!). For models with an unlocked bootloader, you can try reflashing the device via Fastboot:

fastboot flash system system.img


fastboot flash boot boot.img




fastboot reboot

Warning! Fastboot flashing deletes all data and can lead to a blink if incompatible firmware files are used. For Xiaomi with a locked bootloader, this method is not suitable.

3. Hardware malfunctions: when blinking is a symptom of a breakdown

If software methods fail and the indicator flashes continuously or at non-standard intervals (e.g., 3 short + 1 long), this may indicate a hardware problem.

Especially dangerous is the case when the indicator flashes when the phone is turned off - this may mean that the device does not turn off completely due to:

• 🔋 Faulty battery (swelling or with damaged contacts).
• 🔌 Sticky power button (phone "thinks" it's being held).
• 🔥 Overheating of the chipset (for example, after falling or getting moisture).

⚠️ Attention! If the phone doesn't turn on but the light flashes, don't plug it into charging before the diagnosis! This can aggravate the short circuit. Xiaomi's service center only classifies these cases as "warranty" if the device hasn't been dropped or disassembled by itself.

On the POCO F4 GT and Black Shark models, a flashing indicator can signal that the gaming chipset is overheating. Check the temperature through the CPU Monitor app - if it is above 60°C, let the phone cool down.
