Xiaomi phone glitches on Android: what to do if the system slows down, crashes or does not respond

Your Xiaomi has started to slow down, spontaneously reboot or give out “Application Stopped” errors? Such failures are found even on flagships like the Mi 13 Ultra or Redmi Note 12 Pro+ – the fault can be both software bugs in MIUI and hardware problems. In 80% of cases, the problem can be solved without going to the service center, but it is important to act on the algorithm: from simple steps to complex ones.

The first thing to understand is that "glitches" are a generalized concept, and it can be hidden under it.

• 🐢 Slow-motion interface (lags when scrolling, freezes when opening applications).
• 🔄 Cyclic reboots (the phone turns on, shows the Xiaomi logo, then switches off again).
• 🚫 App departures (especially often affected by Google Play Services, Mi Video, Camera).
• 📵 A broken touchscreen or button (sensor not responding to touch, volume/power buttons jammed).
• 🔋 Battery power jumps (e.g., from 50% immediately to 15% or shutdown at 30%).

In this article, we'll look at all the possible causes, from CPU overheating to firmware conflicts, and give you step-by-step instructions for each. We'll focus on Redmi and POCO models, which are most likely to suffer from MIUI bugs due to aggressive system optimization. If your phone is still warranty, some methods (like unlocking the bootloader) can cancel it - keep that in mind.

1.Reboot the phone: the simplest way to "resuscitate"

It sounds trivial, but a forced reboot solves up to 30 percent of the problems with the glitches, especially if the phone:

• 📱 Hovers on the MI logo or download animation.
• 🖥️ No touch response, but the screen is on.
• 🔄 It spontaneously goes into reboot.

How to reboot Xiaomi if it doesn’t respond:

1. Press the power button for 10-15 seconds (on some models – together with the volume button).
2. If the screen goes out and the logo appears, release the buttons. The phone should boot in normal mode.
3. If the glitches remain after the reboot, try Safe Mode (about it below).

On non-removable battery models (all modern Xiaomis), the forced reboot is safe — it won’t damage the hardware. But if the phone doesn’t turn on at all (no vibration, no charging indicator), the problem may be in the battery or motherboard — you already need diagnostics in the service.

2. Launch in Safe Mode: Checking the culprit

Safe Mode boots the system without third-party apps, and if it's stable, it's a problem in one of the apps you've installed, and if there's a bug, it's the firmware or the hardware.

How to run Safe Mode on Xiaomi:

1. Turn off the phone (if it freezes, use the forced reboot from the previous section).
2. Press the power button before the MI logo appears.
3. Once the logo appears, immediately press and hold the volume button until the phone boots.
4. At the bottom of the screen should appear the inscription Safe Mode.

Now check:

• ✅ Does the touchscreen work without hanging?
• ✅ Whether system applications (Settings, Phone, Messages) are opened.
• ✅ Are there lags when scrolling the menu?

If everything is working normally in safe mode:

Remove recently installed applications (especially from unverified sources)|Clear the cache for all applications in Settings → Annexes|Check the autoboot in Settings → Battery → Auto-start|Update problematic apps through Google Play-->

3. Cleaning the cache and application data

Cache is one of the main reasons for lags on Xiaomi. MIUI system actively uses cache to speed up work, but over time it can damage or grow to giant sizes (especially Google Play Services, Mi Video, Gallery).

How to clear the cache:

1. Go to Settings → Applications → Application Management.
2. Select an app that is buggy (like Camera or Google Chrome).
3. Click Clear Cache. If the problem is serious, select Clear Data (Warning: this will delete all app settings!).

For mass cleaning:

1. Go to Settings. → Memory.
2. Click Clean (the system will prompt you to delete unnecessary files, cache and debris).
3. Or use the built-in Security → Cleanup app.

Do not clear system application data (Settings, Google Play Services, Mi Account) unless absolutely necessary – this may result in a Mi Account crash or loss of communication with Google servers.

4. firmware update: fixing MIUI bugs

Xiaomi regularly releases updates for MIUI that fix critical bugs. If your phone is bugging after the last update, there may be patches that solve the problem.

1. Go to Settings → About Phone → MIUI version.
2. Remember the current version (e.g. MIUI Global 14.0.5).
3. Return to Settings → System Update and click Check Updates.

If the update is available:

• 📥 Download it over Wi-Fi (not mobile internet!)
• 🔋 Make sure the battery is charged >50%.
• ⏳ Do not interrupt the process (may take 10 to 30 minutes).

If the phone stopped turning on or stuck on the logo after the update, it's a sign of a bad firmware.

1. Press the power + increase the volume for 10 seconds for a forced reboot.
2. If it doesn’t work, go through Fastboot (instructions in Section 6).

💡

Before updating, back up important data via Settings → Additional → Backup and Reset. In case of a crash, you can restore contacts, SMS and settings.

5.Resetting settings to factory: the last chance without service

If none of the previous methods worked, hard reset remains, which will delete all data from the phone, including apps, photos and settings, but return the system to a “clean” state. On Xiaomi models with bootloader lock (all modern devices), the reset will not delete the Mi Account — it will have to be re-entered after turning on.

How to reset:

1. Go to Settings → Additional → Backup and Reset → Reset settings.
2. Choose to erase all data.
3. Confirm the action (you may need to enter a pattern lock or password).
4. Wait until the phone is finished (it will reboot several times).

If the phone doesn’t turn on or is stuck on the logo, use a hardware reset:

1. Turn off your phone (if necessary).
2. Press the power + increase the volume before the Recovery menu appears.
3. Select Wipe Data (manage by volume buttons, confirm by power button).
4. Confirm Yes and wait until it is completed.

Attention, after discharge:

• 🔒 You will need to enter a Mi Account that was linked to your phone (if you had one).
• 📱 All data will be deleted without recovery (if there was no backup).
• 🔄 The first 10-15 minutes after a reset, the phone may slow down — that’s normal (the system indexes files).

💡

Resetting only removes user data, but does not fix hardware problems (such as a faulty battery or damaged memory).

6. Fastboot Flash-through: for power users

If the phone doesn't turn on, freezes on the logo, or cyclically reboots, and the reset doesn't work, you just have to reflash it through Fastboot, which requires a PC, a USB- cable, and basic knowledge of working with ADB.

What you need:

• 💻 Computer with Windows/Linux/macOS.
• 🔌 Original. USB-cable (not cheap charging!).
• 📥 Firmware for your model (download only from the official Xiaomi website).
• 🛠️ Mi Flash Tool and the Mi Flash Tool ADB/Fastboot.

Step-by-step:

1. Download and install Mi Flash Tool (for Windows) or fastboot for your OS.
2. Unpack the firmware (file with the extension.tgz or.zip) in a folder without Cyrillic characters.
3. Turn off the phone and turn it into Fastboot mode: Press the power button + volume reduction for 5-10 seconds. Release when the hare appears in the hat-eared (Fastboot logo).
4. Connect your phone to your PC and start the Mi Flash Tool.
5. In the program, click Select, specify the path to the unpacked firmware.
6. Select Clean All mode and press Flash.
7. Wait for the end (10-20 minutes) and the phone will reboot automatically.

Attention, flashing through Fastboot:

• ❌ Deletes all data without recovery.
• ❌ Can lock your phone if the firmware isn't right for your model.
• ❌ Cancellates the warranty if you use unofficial firmware.

7. Diagnostics of hardware problems

If the software methods didn't help, the problem could be the hardware.Typical hardware issues on Xiaomi:

How to check the hardware:

• 🔋 Battery: Install the AccuBattery app and check the actual capacity. If it's less than 80 percent of the declared capacity, it's time to change the battery.
• 🌡️ Overheating: Use the CPU Monitor to monitor the temperature of the processor. Normal to 45°C in plain, up to 60–70°C under load.
• 🛠️ Display: If the screen flickers or artifacts (strips, dots) appear, check the plume. On models with AMOLED (e.g. Mi 11), burn-in (pixel burnout) is possible.

Don’t take your hands off if you don’t have experience – modern Xiaomis (like the Redmi Note 12 or POCO F5) use brittle plumes and glue that are easily damaged, which can result in a total loss of warranty.

8.When to contact the service center

If you have tried all the methods, but the phone is still:

• 🔄 Cyclically rebooting.
• 📵 Does not turn on or respond to charging.
• 🔥 Overheating without loading.
• 💥 Issuing firmware errors (Fastboot or Recovery).

It's time to call the experts.

Where to repair Xiaomi:

• 🏢 Official service centers: Keep warranty, but repairs can take 1-2 weeks.
• 🔧 Unofficial workshops: Faster and cheaper, but risk poor repairs. Look for reviews on 2GIS or Yandex.Maps.
• 📦 Self-replacement: Only if you are confident in your abilities.Save parts are ordered on AliExpress (sellers with a rating of 98%+) or in trusted stores (for example, Mobilparts).

Average repair prices (for 2026):

Attention, before you visit the service:

• ✅ Back up your data (if the phone is still on).
• ✅ Write IMEI (on the box or under the battery) to help avoid replacement parts.
• ✅ Check if the warranty card has expired (usually 12 months from the date of purchase).
