Changing a smartphone always causes stress, not so much because of the device itself, but because of the need to transfer a huge amount of data. Ecosystem owners Samsung Samsung is in a better position because the Korean giant has developed powerful synchronization tools. However, many users are still looking for ways to transfer files from Samsung to Samsung via Wi-Fi, fearing quality loss due to compression in messaging apps or lack of a suitable cable.
Modern wireless communication standards allow for the establishment of a data transmission channel at a speed comparable to a wired connection. Using the protocol Wi-Fi Direct or proprietary utilities like Smart Switch Guarantees not only speed but also the security of your personal photos and documents. Unlike cloud storage, local Wi-Fi transfers don't consume mobile data or require internet access.
In this article, we'll cover all available methods in detail, from built-in system functions to third-party solutions. You'll learn how to set up a direct connection between devices, which security settings to check, and how to avoid common data migration mistakes. Properly setting up the communication channel is key to the fast and reliable operation of your devices.
Preparing devices for wireless data transmission
Before starting any data transfer operation, you need to ensure that both smartphones are ready to use. This is a basic step, and ignoring it often leads to connection errors or interruptions mid-transfer. Make sure both devices—the old and the new one—are ready to use. Samsung Galaxy — the battery is at least 50% charged.
The second important step is checking the operating system versions. Although modern transfer methods are usually cross-platform, the availability of current updates Android and shells One UI Minimizes the risk of software conflicts. Go to settings and check for updates to eliminate communication protocol compatibility issues.
- 📱 Turn on Wi-Fi on both devices, even if you don't plan to connect to an internet router.
- 🔒 Unlock the screens of both smartphones, as the security system may interrupt the connection when switching to sleep mode.
- 📶 Disable power saving mode, which may limit background activity of network modules.
⚠️ Important: If you are using corporate profiles or VPN connections, temporarily disable them. They may block local device discovery on the network.
It's also worth freeing up space on the receiving device. Transferring large amounts of data, such as 4K video or RAW photos, requires significant space. Check the available memory in the Settings → Device Maintenance → Storage.
Using Samsung Smart Switch via Wi-Fi
The most effective other way to migrate data is through an application Smart SwitchIt comes pre-installed on most modern Samsung smartphones, but if you don't have it, you can easily download it from Galaxy Store or Google PlayThis application can work both via cable and wirelessly, creating a secure tunnel between devices.
To get started, launch the app on both phones. On the old device, select "Send data," and on the new one, select "Receive data." The system will prompt you to select a connection type: cable or wireless. Select wireless connection, after which the search for available devices within the range of the Wi-Fi module will begin.
☑️ Smart Switch Pre-Launch Check
Once the devices are detected, a confirmation code will appear on the screens. Make sure the codes match and tap "Confirm" on both smartphones. The data analysis process will begin, which may take several minutes depending on the amount of data. You can choose what you want to transfer: contacts, messages, apps, home screen settings, or media files.
| Parameter | Description | Recommendation |
|---|---|---|
| Transfer speed | Depends on the Wi-Fi standard (ac/ax) | Use the 5 GHz band |
| Security | WPA2 encryption | High level of protection |
| Distance | Up to 10-15 meters | Keep devices close |
| Stability | High | Don't switch between applications |
It's important to continue the process and keep both screens on. Smart Switch will automatically recreate the folder structure and icon arrangement on the new device, significantly saving setup time.
Setting up a Wi-Fi Direct connection
Technology Wi-Fi Direct Allows devices to connect directly to each other, without the need for a wireless router or access point. It's ideal for quickly transferring large files, such as videos or photo archives, when a cable is not available.
To activate this mode, go to the Wi-Fi settings on both devices. In the additional settings menu (often hidden under three dots or the "More" button), find the option Wi-Fi DirectOnce this feature is enabled, your phone will begin scanning its surroundings for available devices.
Why is Wi-Fi Direct faster than Bluetooth?
Wi-Fi Direct uses the same frequencies and modulation standards as regular Wi-Fi, providing throughput of up to 250 Mbps and higher. Bluetooth, on the other hand, is limited to significantly lower speeds, making transferring gigabytes of data extremely slow.
When you see the second smartphone's name in the list of available devices, tap it. A connection request will appear on the second phone's screen, which you must accept. Once the connection is established, you can use the standard file manager or gallery to send files.
- 🚀 Data transfer speed can reach tens of megabytes per second.
- 🔋 Battery consumption is lower than when using an access point, but higher than in standby mode.
- 📡 The range is about 100 meters in open space.
It's worth noting that Wi-Fi Direct doesn't always display a progress bar in the system notification as clearly as Smart Switch does. Therefore, monitor the transfer progress through your file manager notifications.
Sharing via Quick Share (formerly Nearby Share)
Function Quick Share (formerly known as Nearby Share) represents an evolution of file sharing methods, combining Bluetooth for discovery and Wi-Fi Direct for data transfer. It's a native Android tool that's deeply integrated into the system and works incredibly quickly between Samsung devices.
To use Quick Share, make sure the feature is enabled in the Quick Settings menu. You can also set the visibility: "Contacts Only" or "All Devices." Choosing the latter will make your phone visible to all nearby devices, which is convenient in a group setting, but requires caution in public places.
The transfer process is simple: select a file in your gallery or file manager, click the Share button and select the icon Quick ShareThe phone will automatically locate the nearest Samsung device and prompt you to send the file. The recipient will receive a notification with a file preview and will be asked to confirm receipt.
The advantage of this method is its versatility: it works even if the device screens are locked (with appropriate visibility settings), and the transfer can occur in the background. Files are automatically sorted into the appropriate folders on the receiving device.
Create a mobile hotspot for file transfer
If standard methods don't work for some reason, or you want to create a stable local network for file transfer via an FTP server or file manager, you can use modem mode. One Samsung smartphone becomes the router, and the other connects to it as a client.
Turn on Mobile Hotspot on the first device via the menu Settings → Connections → Mobile HotspotSet a password and network name. On the second device, find this network in the list of available Wi-Fi connections and enter the password.
Once connected, both devices are on the same local network. You can now use network file management apps (such as Solid Explorer or ES File Explorer) to access the storage of one phone from the other via SMB or FTP. This gives you full access to the file system.
⚠️ Note: When using a hotspot without a SIM card or with an unlimited data plan, it's best to turn off mobile data to avoid accidental data consumption, although local data transfers between connected devices do not consume data.
This method requires more technical knowledge to set up access paths, but it is indispensable if you need to transfer terabytes of data or work with the file system directly.
Troubleshooting and speed optimization
Despite the reliability of these technologies, users may encounter issues such as slow speeds, connection drops, or devices failing to recognize each other. Often, the cause lies in interference in the air or outdated Wi-Fi module drivers.
If your transfer speed has dropped, try switching your Wi-Fi frequency. Many routers and smartphones operate in the 2.4 GHz band, which is very noisy. Switching to 5 GHz (if both devices support this standard) can increase the speed several times.
It's also worth checking whether the system is restricting background app activity. In the battery settings, make sure the file transfer app (Smart Switch or the file manager) isn't in the "sleep list."
- 🔄 Restarting both devices often solves problems with frozen network services.
- 📶 Make sure that Airplane mode or data saving mode is not enabled on your devices.
- 🛡️ Check if your antivirus is blocking local connections.
In some cases, resetting network settings can help. This will delete saved Wi-Fi passwords and Bluetooth settings, but will return the network modules to their factory defaults, eliminating software configuration errors.
