Modern smartphones of the Xiaomi brand are complex computing devices running the shell MIUI or the new HyperOS. Sometimes users are faced with a situation when the device begins to behave unpredictable: intrusive banner ads appear, applications fly out immediately after launch, or the device begins to heat up very much even in simple. In such cases, standard reboot methods often do not help solve the problem, since the culprit may be third-party software that conflicts with the system.
To diagnose these failures, there is a special diagnostic tool called Safe Mode, in which the Android operating system boots in a minimal configuration, disabling all third-party applications and leaving only system services, which allows you to determine whether the problem lies in the hardware or firmware itself, or whether the newly installed application is to blame. If the phone is stable in safe mode, then the cause should be searched among the programs installed by the user.
The process of activating this mode on Xiaomi, Redmi and POCO devices has its own features, different from stock Android. Mistakes can lead to an accidental reset or login to other engineering menus such as Fastboot or Recovery. So it is important to follow the algorithm described below clearly to successfully start the diagnosis and return the phone to normal operation without losing personal data.
What is a Safe Mode and Why You Need It
Safe Mode is a special operation of the operating system, designed exclusively for troubleshooting. Unlike normal boot, when the system runs hundreds of background processes, cloud synchronization, widgets and social networks, only basic functionality is activated. System applications such as Calls, Messages, Camera and Settings continue to work normally, allowing the user to check the basic functionality of the device.
The main purpose of using this mode on Xiaomi smartphones is to isolate software conflict. Imagine that you installed a new launcher or battery optimizer, after which the phone began to run out in two hours. In normal mode, it is difficult to know exactly what process consumes resources. In safe mode, all third-party apk files are blocked, and if the problem disappears, you get a direct indication that third-party software is to blame.
⚠️ Warning: While in Safe Mode, you won’t be able to use most of the usual features, such as WhatsApp, Telegram, banking apps or games. the interface may look unusual, and in the corner of the screen will be visible corresponding to the inscription. This is normal system behavior, not a sign of a breakdown.
In addition, this mode is often used to remove viruses or malware that masquerade as system processes and prevents you from removing yourself in normal mode. Since the malicious code is not activated in a safe state, you can go to the settings and painlessly remove the problematic application, and it is a great way to check whether the brakes are caused by a crowded cache or errors in the work of specific Google services.
Preparation of the device before starting the diagnosis
Before you go to the immediate steps of switching the boot modes, you need to perform a number of preparatory steps, which will help to avoid loss of important data and ensure that the process will be successful. First of all, make sure that the battery level is at least 40-50%. Although safe mode does not require intensive work of the processor, interruption of the boot due to the dead battery can lead to damage to the file system.
The second important step is to save important data, and while logging into safe mode does not delete photos, contacts, or correspondence by itself, unstable system performance can lead to a complete device failure at any time. It is recommended to back up via the Xiaomi Cloud or Google Drive cloud. USB cables, Bluetooth headsets and take out SIM-card if there is a suspicion that the problem is related to the network module.
☑️ Checklist of preparation for diagnosis
If the device is enabled screen lock, remember the pattern lock, PIN-code or password. In some versions MIUI After booting in Safe Mode, the system may require proof of ownership identity to access settings. Lack of access to the device may block the ability to exit diagnostic mode if standard methods fail.
How to enter safe mode on different versions of MIUI
The Safe Mode activation algorithm on Xiaomi devices can vary depending on the version of the Android operating system and the MIUI/HyperOS shell. There are two main methods: software (through the off menu) and hardware (using physical buttons).
The software method requires you to press the power button to trigger the turn off menu. The "Stop" and "Reset" options will appear on the screen. You need to press and hold your finger on the "Stop" icon (or "Reset" on some models) for 3-5 seconds. A pop-up will appear on the screen asking about the transition to Safe Mode. After confirmation, the device will reboot, and you will see the corresponding inscription.
Algorithm of action:
1. Press the power button.
2. Press and hold "Switch off" on the screen.
3. wait for the confirmation window to appear.
4. Press "OK."If the software method doesn't work, as it does on older firmware or when there's a serious touchscreen hang, the hardware method is used. You have to turn off the phone completely. Then you have to hold the power button and the volume button at the same time ("Loudness down"). You have to hold them until the Mi or Redmi logo appears. Once the logo appears, the buttons need to be released. If done correctly, the device will boot in diagnostic mode.

Diagnostics and removal of problematic applications
Once you have successfully booted into safe mode, you will have a clean interface. First, check if the problem that you've been bothering about is still there. If the phone stopped warming, the ads disappeared, and the system is running smoothly, then the cause is found, it's a third-party application. Now your task is to identify the culprit. Remember which programs you installed or updated just before the bugs appeared.
To remove suspicious software, go to Settings → Apps → All apps. Carefully review the list. Often malware masquerades as system processes or has no icons. Look for apps with strange names, no name, or ones you don't remember installing. Click on the suspicious item and select "Delete."
| Type of application | Signs of malignancy | Action. |
|---|---|---|
| Memory optimizers | Promise to speed up the phone in 2 times, show ads | Delete immediately |
| Lanterns and scanners | Requires extra permissions (access to contacts, GPS) | Remove, replace system |
| Games from unknown sources | Installed by Google Play, have strange names | Delete and check with antivirus |
| System updates (fake) | Android icon, but file name is different from standard | Delete, it's a virus miner. |
If you can't visually identify a problem app, you can go with the elimination method. Remove the last installed programs one at a time, rebooting the phone to normal mode for each check. This process can take time, but it ensures that the source of the conflict is located. It's also useful to check the Special Options section in the settings, since viruses are often prescribed there to obtain rights on top of other windows.
💡
The main goal of safe mode is not work, but to find and remove the culprit of instability. Don't try to use your phone as usual, focus on cleaning the system.
How to get out of Safe Mode on Xiaomi
Many users who have successfully solved their problem or just checked the system are faced with the question: "How to get back?" Fortunately, the exit from Safe Mode on Xiaomi is implemented as simple as possible and does not require complex manipulation. In 99% of cases, it is enough to perform a normal full reboot of the device, the system automatically determines that the user did not request a re-entry into diagnostic mode, and will start in normal mode.
To do this, press the power button and select the Reboot option. Do not select Turn off, as on some models, after completely turning off and on, the mode may remain if a combination of buttons was used. It is the Reboot function that guarantees a safe boot flag reset. Once turned on, the Mi or Redmi logo should appear without the inscription “Safe mode” in the corner of the screen.
⚠️ Warning: If after a normal reboot, the phone boots back up in safe mode, don't panic. Try turning the device off completely, wait. 10-15 In rare cases, you may need to repeat the reboot procedure. 2-3 once.
There is also a situation where the volume button is physically stuck or crashed. Since the safe mode entry on many Xiaomi models is tied to the "Loudness Down" button at start, the sticky button will constantly initiate this mode. Check the mechanical state of the buttons, clean them carefully if necessary, or slightly tap the body in the area of the keys to free up the mechanism.
What to do if your phone is stuck in safe mode
There are times when standard exit methods don't help, and the device reboots cyclically into diagnostic mode, which may indicate damage to system files, firmware update failures, or hardware button problems. If a simple reboot doesn't help, deeper recovery methods.
The first step is to clear the system cache. This will require logging into Recovery mode. Turn off the phone, then press both the power button and the volume button ("Loud up"). Hold them until the logo appears, then release power, continuing to hold the volume until the Recovery menu appears. In this menu (manage volume buttons, select power buttons), select Wipe Cache (not to be confused with Wipe Data!).
If cleaning the cache didn’t help, it might be the files of the downloading app itself or the incorrect version of the firmware installed, and you might need to reset to the factory settings (Wipe Data). Remember, this step will completely delete all your data (photos, contacts, apps), so you should only resort to it if you have a backup or data is not important.
💡
Before performing a full reset (Wipe Data), try just to remove it. SIM-Sometimes a damaged sector on the memory card or a faulty operator profile can block the normal system load.
