Owning a modern smartphone like the legendary Redmi Note 4 involves constantly working with huge amounts of information. High-resolution photos, videos, documents and music files quickly occupy the internal memory of the device. Sooner or later, every user faces the question: how to transfer data from a phone to a computer to make room or create a backup?
There are many ways to synchronize, from classic wired connections to wireless cloud technologies. The choice of a particular method depends on the amount of information transmitted, the availability of a cable and the speed of your Internet connection. In this article, we will discuss all the current options in detail so that you can choose the most convenient for your situation.
It's important to understand that the MIUI operating system installed on your device has its own features of interaction with external drives. Incorrectly configuring the USB interface can lead to the fact that the computer simply will not see the phone. We will eliminate this problem and consider the nuances that beginners often miss when connecting for the first time.
Device preparation and cable selection
Before you start transferring files, you need to make sure that the physical connection is working properly. Often users are faced with a situation where the phone is charging from the cable, but the computer does not respond to the connection. This is due to the fact that many cables that come with cheap accessories are “charging” and do not have internal lines for data transfer. To successfully synchronize, you will need a quality Micro-USB cable with data transfer support.
Also worth checking is the smartphone connector itself. In the Redmi Note 4 series, which have been in active use for years, dust and pile often accumulate in the charging port. This can prevent tight contact of contacts. Carefully clean the connector with a dry toothbrush or wooden toothpick to rule out mechanical problems with the connection.
⚠️ WARNING: Using damaged or too cheap cables without shielding can lead to unstable data transfer and even damage your smartphone’s power controller or computer motherboard.
After checking the cable, make sure that the required drivers are installed on your computer. In modern versions of Windows 10 and 11, the system usually automatically finds the right components for working with Android devices. However, if you are using an older OS or a specific build, you may need to manually install ADB drivers or Google USB Driver components.
☑️ Checking before connection
Method 1: Wired connection via USB (MTP mode)
The fastest and most reliable method to move gigabytes of information in minutes is the use of the computer. USB-When you connect your smartphone to your PC, you often activate Charge Only by default. To get your computer to see the file system, you need to change this setting manually. Lower the notification curtain on your phone screen and find the notification Charge through USB" (You can click on it and select a mode. MTP (Media Transfer Protocol).
After the regime's selection MTP You'll see a new removable device on your computer screen, and you'll have access to internal memory and, if you have it, a memory card. SD-The structure of folders in Android is organized logically: photos are usually in a folder. DCIM, Download – in Download, and documents can be scattered across different application directories.
When working with large amounts of data, for example, when copying video in 4K, The speed of the recording may vary. It depends on your class. SD-maps and versions USB-For maximum performance, connect the cable directly to ports on the PC motherboard, avoiding the use of USB-hubs without additional power.
| USB mode | Description | What is used for |
|---|---|---|
| Just charging. | Data transmission disabled | Safe charging in public places |
| MTP (Media Transfer Protocol) | Transfer of media files and documents | The main mode for working with files |
| PTP (Picture Transfer Protocol) | Transmission of photographs only | For older PCs or specific software |
| MIDI | Use as a musical instrument | Connecting to synthesizers and DAWs |
💡
If your computer can't see your phone in MTP mode, try switching to PTP mode, copying the photo, and then coming back, sometimes it wakes up Windows drivers.
Configure access to the MIUI file system
Xiaomi’s MIUI shell is known for its aggressive security and optimization policies. Some firmware versions may require debugging or file permission confirmation when you first connect to a new computer. If a window pops up asking “Allow data access?”, be sure to click “Allow” or “OK” otherwise the computer’s file manager will display an empty folder.
Also, you should pay attention to the default USB settings. You can set the phone to always request action when you connect or automatically go to file transfer mode. To do this, go to the developer menu. To activate this section, go to Settings → About Phone and quickly click 7 times on the MIUI Version. Once you have the "You became a developer" sign, go to Advanced Settings → For developers.
In the developer menu, find the default USB configuration, where you can select the behavior of your device when you connect to your PC, and you should leave the value "File Transfer" or "Always Ask" to have control over your connection, which is especially important if you often connect your phone to other people's computers or charging stations in public places.
⚠️ Note: Do not turn on the "Debugging" mode USB", If you're not sure what you're doing, and you don't know why you need it, it gives you full access to the system and can be used by attackers when you connect to an infected PC.
Wireless transmission via Mi Drop and FTP
If you don't have a cable on hand, or if the phone connector is loose, wireless technology comes to the rescue. The MIUI shell has a great Mi Drop tool built in (the new versions may call it ShareMe), it's analogous to Apple's AirDrop, but it's powered by Wi-Fi Direct. To transfer data to your computer, make sure both devices are connected to the same Wi-Fi network, or create an access point on your phone.
An even more advanced method available out of the box through a standard conductor is FTP-Open the Explorer app, go to category and select FTP. Click "Run." The phone will give you the address you want to type into the address bar of any file manager on your computer (like "My computer" or Total Commander: ftp://192.168.1.55:2121.
Advantage FTP-The method is that it does not require additional software to be installed on a PC and works even through firewalls, since it uses standard ports. The transfer speed depends on the quality of your router and the Wi-Fi range (5 GHz is much faster than 2.4 GHz). This method is ideal for fast transfer of several files without wire search.
Why can FTP be faster than the cloud?
Cloud storage and synchronization
Cloud technology has become the standard for anyone who wants to access their data from any device. For Xiaomi users, the Mi Cloud service is most deeply integrated, but for cross-platform work (Android + Windows), the Google One ecosystem is best suited. Photos and videos can be automatically uploaded to Google Photos, freeing up space on the device with the “Free Space” function.
For documents and heavy files, it's convenient to use Google Drive or Yandex.Disk. These services have handy PC apps that create a virtual drive on the system. You just drag and drop files into a folder on your computer and they automatically appear on your phone, and vice versa. This ensures continuity of workflow without the need for manual copying.
The main disadvantage of cloud methods is the dependence on Internet connection speed and free space limits. Free rates usually offer 5 to 15 GB, which quickly ends with video backup. Therefore, the cloud is better used for critical documents and photos, and full copies of the system or heavy media are stored on physical media.
Solving Connection Problems
Despite the simplicity of the procedures, users often encounter errors. If the computer makes a sound of the device's connection, but nothing happens, try replacing it. USB-Ports on the front of the system unit often have poor contact or power shortages.Always use ports USB 3.0 (blue) on the back of the motherboard for maximum speed.
Another common problem is antivirus blocking. Some aggressive antivirus programs may be considering a new one. MTP-Disable the device as a potential threat and block access to the file system. temporarily disable the protection or add the device to exceptions to check if this is the reason for the attack.
If the phone is charging but not detected in any mode and the reboot is not helping, it may be the Micro-USB connector itself that is damaged. In the Redmi Note 4, it is a "disease" of the model due to active operation, in which case only wireless transmission or repair of the connector in the service center remains.
💡
The golden rule of diagnosis is, if you can't see a device on one computer, check it on another computer. If you don't see a reaction, it's a cable or a phone problem. If you can see it, it's a driver problem on the first PC.
