Owners of Xiaomi, Redmi and POCO smartphones often notice a mysterious file called bugreport in their memory. It can take up from several megabytes to several gigabytes of disk space, causing confusion among users. Many immediately begin to look for ways to delete it, fearing viruses or malfunctions in the MIUI or HyperOS operating system.
In fact, this file is not malware or an error that needs to be urgently fixed, it's a system tool that developers have created for diagnostics, but in everyday use, it is often useless for the average person and only takes up precious space.
In this article, we will discuss in detail the purpose of this report, its origins and safe cleaning methods, why the system creates this data and whether it is worth blocking it in the future, and understanding the processes that take place inside the smartphone will help you manage free space more effectively.
Purpose and functions of the system report
The bugreport file is a detailed log file that the Android operating system creates lapses in time, and its main task is to collect complete information about the state of all running processes, memory usage, CPU operation and network connections. For Xiaomi engineers, it is an invaluable tool to reproduce and correct errors.
When an application crashes or the system freezes, the report-making mechanism captures a snapshot of the device's state, and it contains error text, call stacks, and other technical information, and unless you're a developer or tester of firmware betas, you don't need that data.
⚠️ Note: The bugreport file contains technical information about the operation of the system, but does not store your personal photos, correspondence or passwords.
Often users confuse this file with system errors, but it is only the result of a debugging mechanism, and the presence of a large number of such files may indicate that applications or the MIUI shell itself often fail in the background.
💡
Bugreport is a diagnostic tool for developers, which in the usual mode of use of the smartphone does not bring any benefit to the user, but only takes up space.
Where is the file and why is it growing?
By default, the system places error reports into the device's internal memory. Most often, the path to the file looks like /data/tombstones or the root directory of internal memory if the appropriate debugging option is enabled, and you can find it through the standard MIUI Explorer or third-party file managers.
The size of the file depends on the number of events recorded. If a system crashes, the report can grow instantly, and in some cases, with cyclic errors, the size can reach several gigabytes, which is critical for models with a small amount of internal storage.
The growth in data volume is also linked to user activity: the more applications you use and the more often they run unstable, the more data gets into the log files, and the system automatically adds up this data until the user or memory cleanup deletes it.
- 📂 The path is often hidden in system folders that are only available with root or through permissions. ADB.
- 📈 The size can vary from 1 MB to 5 GB depending on the frequency of failures.
- 🔄 The file can be created again after each device restart if the error is not fixed.
Removal methods through developer settings
The most effective way to prevent new files from appearing and delete old ones is to disable the error reporting function, which requires access to the hidden Developer Menu, which is standard for all Android smartphones.
First, you need to activate the developer mode. Go to the settings, select About Phone, and find either MIUI Version or OS Version. You need to quickly click on this line 7-10 times in a row until you notice that you have become a developer.
Settings → About phone → (Tap 7 times on "Version MIUI")Once activated, go back to the main settings menu and find the "Additional" or "Extended Settings" section, and a new "Developers" option will appear, and you'll find the "Error Report" option inside and switch it to "Off."
☑️ Activation of the developer mode
Once this feature is disabled, the system will stop generating new files if there is a failure, but old files that have already accumulated in memory must be manually deleted through the file manager or storage settings.
Cleaning Memory and Working with ADB
If standard methods don’t help you delete a file or it’s locked by the system, you can use a more advanced tool, USB debugging and the Android Debug Bridge (ADB) console, which requires connecting your smartphone to your computer.
First, make sure that the “Debugging USB” option is activated in the “Development for Developers” menu. Then connect the phone to the PC with a cable. You need to install Xiaomi drivers and the Android SDK Platform Tools platform on your computer.
Open the command line on your computer and enter a command to access the file system. The command to delete a specific bugreport file is as follows:
adb shell rm /data/tombstones/bugreport-*This command will force you to delete all error reports from the tombstones system folder. Be careful when you type commands, as a syntax error can result in the deletion of other important system files.
⚠️ Attention: Use of teams ADB Incorrect deletion of system files can lead to unstable smartphone operation or data loss.
An alternative and safer option for most users is to use the built-in Security or Cleanup app, which automatically finds cache and temporary files, including bugreport residues, and prompts them to be deleted with a single click.
Analysis of causes of appearance and diagnosis
The constant appearance of a bugreport file can signal deeper software problems. If the file occurs regularly, it is worth analyzing which applications you have recently installed, often caused by unoptimized programs from third-party sources.
Also, the cause may be damage to system files after a failed firmware update, in which case deleting the file will only have a temporary effect, it is recommended to check for system updates or reset the settings to factory.
| Cause of the occurrence | Probability. | Decision |
|---|---|---|
| System application failure | Tall. | Cleaning the app cache |
| Mistake after MIUI update | Medium | Waiting for a patch or reset |
| Third-party software conflict | Tall. | Removal of recent applications |
| Lack of RAM | Low. | Closing of background processes |
Diagnosing a problem takes time, but helps prevent future crashes.If the bugreport only appears when a particular game or program is launched, the problem is localized to that application.
Can I ignore the bugreport file?
Prevention and optimization of the system
To avoid overflowing with system debris in the future, it is recommended to regularly prevent.Use built-in optimization tools that come with the HyperOS shell.
Do not install applications from unknown sources. APK-Files from dubious sites often contain code that causes conflicts with the system, which leads to the generation of error reports.
- 🧹 Clean up your garbage once a week through the Security app.
- 📲 Keep an eye out for app updates in the store.
- 🚫 Avoid installing “heavy” modified versions of popular programs.
Timely firmware updates are also important: Xiaomi engineers are constantly releasing bug fixes that caused the creation of unnecessary logs. Ignoring updates can lead to an accumulation of errors.
💡
If the bugreport file appears immediately after the phone is turned on, try restarting the device to Safe Mode, which will help determine if the third-party app is to blame.
