⚠️ Attention: When transferring confidential data (passwords, documents), make sure that both devices are connected to the same Wi-Fi networkUsing public access points (cafes, airports) increases the risk of traffic interception.

Method 1: Built-in Windows tools (without programs)

If you have Windows 10/11, you can do it without third-party software. Function Projection onto this computer allows you to broadcast your smartphone screen to your PC, and Nearby Devices — exchange files.

How to enable:

  1. On PC: Open Settings → System → Project to this PC.
  2. Select "Available everywhere" or "Available everywhere on networks".
  3. On your smartphone (Android): open Settings → Connected devices → Screen projection and select your PC.
  4. On iPhone: use the function Screen Mirroring (in the control panel).

To transfer files:

  • On PC: Settings → Devices → Nearby devices → turn on the function.
  • On your phone: In File Explorer, select the file → Share → Nearby Devices.
⚠️ Note: The Nearby Devices feature only works with Android 8.0+ And Windows 10 (version 1803 and later)This option is not available on iPhone; use iCloud or AirDrop.

Method 2: File transfer apps (LocalSend, Snapdrop)

Standard Windows and Android tools often have glitches or limited functionality. It's much more convenient to use specialized apps that:

  • 📎 Works without registration and cloud servers.
  • 🔗 Support direct transmission between devices (P2P).
  • 📂 Allows sending entire folders, and not just individual files.

Best options:

Application Platforms Max. speed Peculiarities
LocalSend Windows, Android, iOS, Linux Up to 50 Mbps Open source, encryption
Snapdrop Any (works in browser) Up to 30 Mbps No installation required, but requires one network
Feem Windows, macOS, Android, iOS Up to 100 Mbps Supports broadcast history, but there are ads

Instructions for LocalSend (the most reliable option):

Install the application on your PC and smartphone (download from official website)

Open LocalSend on both devices

Press "Send" on your phone and select the file

Select your PC from the list of devices

Confirm receipt on your computer-->

If the devices do not see each other:

  1. Check that both are connected to one Wi-Fi network (not to mobile data!).
  2. In the router settings, open Local Area Network (LAN) → Client Isolation And turn it off this function.
  3. On Android, check the resolution "Near Field Communications" in the application settings.

Method 3: Remotely control your smartphone from a PC (Vysor, Scrcpy)

Sometimes you need to do more than just transfer files, fully control your phone from your computer — for example, for testing apps, streams, or convenient text input. There are two types of programs for this:

  • 🖥️ Screen mirroring (view without control) - ApowerMirror, TeamViewer QuickSupport.
  • 🎮 Full control (mouse + keyboard) - Vysor, scrcpy.

Scrcpy — the fastest and easiest solution (works without lag even on low-end PCs). Installation:

1. Download scrcpy from GitHub (https://github.com/Genymobile/scrcpy)

2. Connect your phone via USB and enable debugging (Settings → Developer options → USB debugging)

3. Run scrcpy.exe - the phone screen will be displayed on the PC

4. To work via Wi-Fi, enter the command:

adb tcpip 5555

adb connect [phone IP address]:5555

For iPhone will do QuickTime Player (built into macOS) or ApowerMirror (requires installation on both devices).

⚠️ Attention: When connecting for the first time scrcpy may give an error "device unauthorized"To fix this, check the debugging permission in the menu on your phone. Settings → Developer options → Enable USB debugging.

Method 4: Using an FTP server on your smartphone

If necessary regularly exchange large files (for example, videos or backups), it's more convenient to set up an FTP server directly on your phone. This will allow you to connect to it as a network drive.

Instructions for Android:

  1. Install the application FX File Explorer or Solid Explorer.
  2. Open the side menu → FTP server"Launch".
  3. Remember the address of the form ftp://192.168.x.x:xxxx.
  4. On your PC, open This PC → Map Network Drive.
  5. Enter FTP address, login (anonymous) and password (usually empty).

For iPhone will do FileExplorer Free or Feem (in FTP mode). The transfer speed depends on the router - on Wi-Fi 6 can reach 100+ Mbps.

How to speed up FTP transfer?

1. In the router settings, enable Jumbo Frames (if supported).

2. Use an FTP client on your PC (e.g. FileZilla) instead of the standard conductor.

3. Disable your antivirus software during the transfer—it may scan each file.

Method 5: Connecting via a router (DLNA, Samba)

If both devices are connected to the same router, you can use protocols DLNA (for multimedia) or Samba (for files). This is convenient for:

  • 🎵 Stream music/video from PC to phone (and vice versa).
  • 📁 Access shared folders without transferring files.
  • 🖼️ View photos from your phone on a big screen.

Setting up DLNA:

  1. On PC: Turn on Settings → Network & Internet → Sharing options → Media streaming.
  2. On your phone: install BubbleUPnP (Android) or nPlayer (iOS).
  3. In the application, select your PC from the list of DLNA devices.

For Samba (file sharing):

  1. On PC: Open Control Panel → Network Settings → Change advanced sharing settings.
  2. Turn on File and Printer Sharing And Password-protected sharing (disable if the network is trusted).
  3. On your phone: use FX File Explorer"LAN" → "New Connection".
⚠️ Note: Some routers block DLNA/Samba by default. If devices can't see each other, check the router settings section. "Local Network" → "Multicast" and turn it on.

Troubleshooting: Why can't my PC see my smartphone via Wi-Fi?

If the connection is not established, please check these points:

Problem Cause Solution
The devices cannot find each other. Different Wi-Fi subnets Connect both devices to the same network (not a guest one!)
Low transmission speed 2.4 GHz channel congestion Switch to 5 GHz or change the channel on your router
FTP/ADB connection error The firewall is blocking ports Add a port exception 5555 (ADB) or 21 (FTP)
Android does not ask for debugging permission Developer mode is not enabled Click 7 times "Build number" in the phone settings

If nothing helps, reset your network settings:

  • On Android: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
  • On PC: Settings → Network & Internet → Network reset.
