Upgrading a smartphone can often be a real quest, especially when you need to transfer gigabytes of photos, contacts, and app settings. Fortunately, the era of wired connections and slow Bluetooth transmissions is becoming a thing of the past, giving way to high-speed wireless protocols. Modern Android smartphones have powerful synchronization tools that allow you to migrate data in minutes without loss of quality.
You don't need to be a tech expert to successfully complete this process, but understanding the basic principles of a local network will help you avoid common mistakes. We'll cover all the current methods, from built-in Google features to specialized software that ensures maximum speed. The key is to choose the method that best suits your specific situation and device model.
Preparing devices for wireless transmission
Before starting the procedure, ensure both devices have the same connection conditions. Ideally, both smartphones should be in the same room, in close proximity to each other. This will minimize the risk of connection interruptions and ensure stable data packet exchange speeds.
Be sure to check the battery level on both devices, as active work Wi-Fi module Encoding files uses a significant amount of power, especially for the processor. If the battery level is below 40%, it's best to connect the devices to a power source to prevent the process from being interrupted mid-process due to one device running low.
⚠️ Important: If you are using a public Wi-Fi network (cafe, airport), make sure that P2P (peer-to-peer) connections are not blocked in your router settings, otherwise direct transmission between devices will be blocked.
It's also worth clearing the system services cache if you notice your phone is running slowly. This can be done through the menu. Settings → Apps → Accessibility → Storage accessFreeing up RAM before starting an operation is a good practice to ensure smooth operation.
Using built-in Google and Nearby Share features
The simplest and most native method, which doesn't require installing third-party software, is to use the Google ecosystem. When you initially set up a new phone, the system will automatically prompt you to copy data from your old device. This method is based on technology Near Share (similar to AirDrop), which creates a direct connection between devices.
To use this method, enable Bluetooth and location services on both phones. On the old device, open the "Share" menu on any file, or select "Set up device" when you first turn on the new smartphone. The system will automatically detect the neighboring device and prompt you to start copying.
- 📲 Make sure both devices are signed into the same account. Google account to synchronize contacts and calendar.
- 🔓 Unlock the screens of both smartphones and confirm the pairing request by checking the digital codes.
- 📂 Select the data categories to transfer: apps, SMS messages, call history, and media.
Why can the process stop at 99%?
Sometimes the system takes a long time to verify the integrity of recent files or update application databases. Don't interrupt the process if the progress bar freezes—this is normal for large data sets.
The advantage of this method is that it automatically restores the folder structure and even the desktop icon arrangement if the launchers are the same. However, the speed may vary depending on the version. Android and the power of Wi-Fi modules.
Transfer files via Google Drive and cloud storage
If a direct connection is unstable for some reason, cloud storage is an excellent intermediary. Google Drive, Yandex.Disk, or Dropbox allow you to upload data to the server and download it on your new device. This method is especially convenient if you've already traded in or sold your old phone and need to retrieve data from a backup.
Go to your phone settings and select the section System → BackupHere you can force a cloud upload of your current data. Make sure Wi-Fi backup is enabled to avoid using up your mobile data, which is often limited.
| Service | Free volume | File type support | Speed (conditionally) |
|---|---|---|---|
| Google Drive | 15 GB | All types (photos, contacts, settings) | High |
| Yandex.Disk | 10 GB | Photos, videos, documents | Average |
| Dropbox | 2 GB | Documents, media | Average |
| Telegram (Favorites) | Unlimited | Files up to 2 GB each | Depends on the server |
If the Wi-Fi router is old and does not support the standard 802.11ac, the process may take several hours.
Using specialized applications (Send Anywhere, SHAREit)
When built-in tools don't work correctly or you need to transfer files between devices from different manufacturers with custom shells, third-party apps come to the rescue. The market leaders are Send Anywhere, SHAREit And XenderThey create their own local Wi-Fi Direct network, ignoring router restrictions.
The principle is simple: you install the app on both phones, select files, and receive a 6-digit key or QR code. Entering this code on the receiving device establishes a direct connection. The speed of these programs is often higher than with standard tools, thanks to an optimized transfer protocol.
- 🚀 Send Anywhere Allows you to transfer files even without installing the application via a web interface in your browser.
- 📡 SHAREit is known for its high speed and the ability to transfer data even without internet access.
- 🔒 Pay attention to permissions: some apps require access to the gallery and file system to function correctly.
⚠️ Warning: Many free versions of these apps are overloaded with ads. Be careful when clicking the "Next" buttons to avoid accidentally installing unnecessary games or memory cleaners.
☑️ Check before launching the application
Transfer via local server (FTP/SMB)
For advanced users who want full control over the file system without unnecessary intermediaries, setting up a local server is a suitable option. Using file managers with FTP or SMB support (for example, Solid Explorer or MiXplorer), you can turn one phone into a network folder.
Launch the "Network Access" or "FTP Server" function in the file manager on the sending device. The app will display an address, for example, ftp://192.168.1.5:2221By entering this address in the file explorer on the second phone (or on a PC), you will have direct access to the files.
Example of connection address:ftp://192.168.0.105:2121
Login: anonymous
Password: (empty)
This method is ideal for transferring structured data and working with system folders that are normally inaccessible. The speed is limited only by your network's bandwidth. Wi-Fi router and frequency range (2.4 GHz or 5 GHz).
Typical problems and solutions
Even if all instructions are followed, problems may still occur. Most often, users encounter a situation where devices "see" each other, but the transfer doesn't start or abruptly ends. This can be caused by power-saving settings that aggressively throttle background Wi-Fi processes.
Try temporarily disabling "Power Saver" mode on both devices. Also, make sure AP Isolation isn't enabled on your router—a feature that prevents devices on the same network from communicating with each other.
- ❌ Connection error: Restart the Wi-Fi modules (turn them on/off in settings) on both phones.
- 📉 Low speed: Switch to the 5GHz band if your router is dual-band, as 2.4GHz is often clogged with neighboring networks.
- 📂 Not all files were copied: Check the free space on the new device and the permissions of the sending application.
⚠️ Note: Menu interfaces and item names may vary depending on the Android version and manufacturer's user interface (MIUI, OneUI, ColorOS). If you can't find a setting, use the search within your phone's settings menu.
Is it possible to transfer data if the screen of one of the phones is broken?
Yes, it's possible, but more complicated. If the sensor works but the image isn't visible, you can connect a mouse via an OTG cable for control. If the sensor doesn't work, you'll need USB debugging support and a connection to a PC to manage files via ADB.
How long does it take to transfer 10GB of data over Wi-Fi?
When using the Wi-Fi 5 (ac) standard and devices are located close to each other, the process will take 5 to 15 minutes. On older Wi-Fi 4 (n) routers, the time may increase to 40-60 minutes.
Will Wi-Fi and app passwords be preserved after the transfer?
When using Google's full backup or manufacturer-provided tools (Samsung Smart Switch, Mi Mover), passwords for Wi-Fi networks and most applications are saved and automatically filled in on the new device.
