Xiaomi phone glitch: what to do if the device brakes, spontaneously reboots or does not work screen

Xiaomi smartphones are some of the most popular on the market due to the price-quality ratio, but even they are not immune to software failures. If your Redmi, POCO or Mi started to “dumb”, spontaneously reboot, do not react to touch or give out application errors, do not rush to carry it into the service. In 80% of cases, the problem can be solved by yourself without special skills.

In this article, we will discuss the top-10 The reasons why Xiaomi is glitching, from banal overheating to firmware conflicts, and give step-by-step instructions for diagnosing and troubleshooting. 12/13, POCO X5 mi 11, Because they're the ones that most often have problems, you'll also learn when to go to the service center, and when a simple reboot is enough.

Before you start taking action, answer two questions: when did the glitches (after updating, dropping, installing the application) and how do they manifest (hangs, artifacts on the screen, system notification errors) will help narrow down the possible causes.

1.Diagnostics of the problem: how to understand why Xiaomi is glitching

The first step is to determine whether the failure is software (related to software) or hardware (hardware breakdown).

• 🔍 Check the charging response: connect the phone to another cable and power supply. If the charging indicator flashes or is missing, the problem may be in the port or battery.
• 📱 Sensor test: try unlocking the screen with a password (if the touchscreen doesn't respond) If the password is entered and the touches don't work, it's the display module's fault.
• 🔄 Forced reboot: press the power button for 10-15 seconds. If the phone reboots, the failure is temporary, if not, a critical system failure is possible.
• 📡 Flight mode: activate it for 1-2 minutes. If the glitches are gone, the problem is in the communication module (antenna or SIM card).

If the phone turns on but immediately turns off or goes into a cyclical reboot, this is a sign of firmware damage (for example, after a failed update), in which case only flashing through Fastboot or Recovery will help.

⚠️ Attention: If the phone falls, gets wet or is subjected to mechanical stress before the glitches, do not try to turn it on. This can aggravate the damage to the board.

2. Software failures: how to fix without resetting settings

In most cases, Xiaomi’s glitches are associated with software bugs that can be fixed without drastic measures.

• 🧹 Cache Clearing: Go to Settings → Annexes → App management, select a problem app (such as Miui Home or Google Play Services) and click Clear Cache».
• 🔄 Update: Check for updates in Settings → The phone. → System updates. Sometimes bugs get fixed in newer versions. MIUI.
• 🚫 Removing Recent Apps: If Glitches Started After Installing the Program, Remove It and Restart Your Phone.
• 📱 Safe Mode: Press the power button, hold the "Stop" button until the "Safe Mode" option appears. It only runs system applications - if there are no glitches, third-party software is to blame.

Pay special attention to the background. Xiaomi has activated aggressive battery optimization by default, which can kill applications, to turn it off:

1. Go to Settings → Battery and Performance → Application Power Management.
2. Select the app that crashes (such as Telegram or YouTube).
3. Set the "No Limits" option.

💡

If your phone starts to glittle after the MIUI update, try rolling back to the previous version via Recovery. To do this, download the firmware from the Xiaomi Firmware website and follow the instructions for your model.

3. Hardware malfunctions: when you need the help of a specialist

If the software methods didn't work, the problem could be the hardware. Common hardware causes of Xiaomi glitches:

• 🔋 Battery wear: If the phone turns off at 20-30% charge or discharges in an hour, the battery needs to be replaced. → Battery → Battery status (on some models).
• 🔥 CPU overheating: With prolonged loads (games, video shooting), the phone can slow down or shut down. CPU Monitor for temperature check.
• 📶 Antenna problems: If the network or Wi-Fi goes missing, the plume of the communication module may have departed (a common problem after falls).
• 💧 Moisture intrusion: Even if the phone hasn't sunk, condensation or high humidity can cause contacts to corrosion. check the moisture indicator (usually under the tray) SIM-map).

Some faults can be diagnosed by error codes, for example, if a “Charge suspended. Temperature too high” (Error 1005) notification appears when charging, this indicates a problem with the power controller. And the message “SIM card not supported” (Error 2203) often means slot damage.

⚠️ Note: If the phone does not turn on after a fall, do not try to disassemble it yourself - this can lead to loss of warranty. LPDDR5 memory (e.g. Redmi) K60) Improper handling of fees often leads to irretrievable data loss.

4. Settings reset: when it really helps

If Xiaomi’s phone is slowing down, apps are crashing, or system errors occur, factory resets may be the solution, but this method should only be used as a last resort, as it deletes all data (photos, contacts, messages).

How to do the reset correctly:

1. Save data: copy files to your PC or Mi Cloud (check that sync is enabled in Settings → Xiaomi Account).
2. Select the type of reset: 🔄 Soft reset: Settings → The phone. → Resetting (saves media files, but removes apps and settings). 🧹 Hard reset: Recovery (removes everything) To get to Recovery, turn off your phone, then press Volume up. + Nutrition.

After discharge:

On models with MIUI 14 and later, you can reset via Fastboot if the phone does not load.

5 Update and Flash: Correcting Errors MIUI

If the bugs started after the system upgrade, it could be a broken firmware, and then you can reinstall MIUI. There are two ways to do this.

• 📲 Through Recovery: Suitable for minor errors. Download the firmware for your model from the official website, rename the file to update.zip And put it in the root of the memory. Then in Recovery, select Install. update.zip.
• 🖥️ Through Fastboot: needed for critical crashes (e.g. bootloop) You'll need a PC with Mi Flash Tool installed and an unlocked bootloader!

For the Redmi Note 12 and later, Xiaomi has introduced an additional protection called Anti-Rollback, which means you can’t roll back to the old MIUI without risking the phone’s “bricking up.”

6.Screen problems: flashing, unresponsive to touch, artifacts

If Xiaomi's screen started flashing, showing stripes or not responding to touch, the reasons could be both software and hardware.

• 🖥️ Check the display: connect the phone to the TV through HDMI (If it's supported, or use Second Space, if there's no artifacts on the outside, the matrix or plume is the problem.
• 🔧 Sensor calibration: enter the code ##6484## (for some models) in the phone dialer and follow the instructions.
• 🔄 Reset screen settings: go to Settings → Display. → Additional settings → Resetting settings.

If the screen is completely black, but the phone is making sounds and vibrating, it's a sign of damage to the backlight or plume. In Redmi Note 9/10 models, a common problem is the plume contacts collapse due to mechanical stress, and the service fixes this malfunction in 1-2 hours.

⚠️ Warning: Do not press hard on the screen if it does not respond - it can damage the matrix. Also avoid using the phone at low temperatures (below) +5°C) as this may cause temporary disruptions OLED-panels.

7. Xiaomi phone spontaneously reboots: causes and solutions

Spontaneous reboots are one of Xiaomi’s most common problems, and the reasons fall into three categories:

1. Software: Application conflict (especially launchers and antiviruses) or damaged firmware or incompatible updates.
2. Hardware: Overheating of the processor (for example, when playing Genshin Impact on the Redmi K50) Failure of the battery or power controller.

Systemic:

• Failure of the kernel (system core)
• Activation of Safe Mode due to critical errors.

If you have a thermal engine error in your logs, it's overheating. If battery voltage is too low, it's a battery problem. If you change the thermal paste, it's a battery replacement.

💡

If the phone only reboots when connected to charging, check the power supply. Using non-original chargers above 30W can cause failures in the power controller (especially on the POCO F4 and Redmi K40).

8.When to contact the service: signs of serious breakdowns

Not all problems can be solved by yourself. Contact Xiaomi Service Center if:

• 💥 The phone does not turn on even after charging and forced reboot.
• 🔥 Overheats without loading (for example, when watching a video).
• 📵 Not defined by a computer in Fastboot or Recovery.
• 💦 Divorces or spots appeared on the screen (a sign of damage to the matrix).
• 🔋 The battery is swelling (this is dangerous for health!).
