Answer 1

Hi, I'm John! I will help you with this.

If you haven't already, please check for a Notification on Your Phone

1. When you plug your phone into the PC, does it show any notification about USB options?
2. If yes, tap on it and make sure File Transfer (MTP) or Media Transfer is selected instead of Charging Only.

If there’s no notification at all, then the issue might be on the PC side, please check some BIOS settings that could affect USB functionality:

USB Configuration in BIOS

• Restart your PC and enter BIOS/UEFI (usually by pressing F2, F10, DEL, or ESC during startup).
• Look for a section like Advanced, Integrated Peripherals, or USB Configuration.
• Make sure USB Controller and Legacy USB Support (if available) are enabled.

Fast Boot Settings

• Some Fast Boot settings can prevent USB devices from initializing properly.
• Try disabling Fast Boot in BIOS and see if that helps.

XHCI Mode (for USB 3.0 Ports)

• If you’re using a USB 3.0 port, check for a setting like XHCI Hand-Off or XHCI Mode and try switching between Enabled, Disabled, or Auto.

After making any changes, save and exit BIOS, then reconnect your phone.

Try the following steps to restore the connection between the Samsung phone and the Windows 10 PC, focusing on the Phone Link/Link to Windows connection (which works over network, not USB):

1. Make sure both devices are ready
   • PC and phone are turned on and near each other.
   • Both are connected to the same Wi‑Fi network.
2. Check the Android phone
   • Update the Link to Windows app to the latest version.
   • Open Link to Windows.
   • Ensure Battery Saver is Off.
   • Ensure Airplane mode is Off.
   • Confirm sign‑in with the same Microsoft account that is used on the PC.
   • Turn off battery optimization for Link to Windows (on many Samsung/Android devices):
     • Go to Settings > Apps > Link to Windows > Battery > Optimize battery usage.
     • Choose All, find Link to Windows, and turn the toggle Off.
3. Re‑link the phone and PC
   • On the phone:
     1. Open Link to Windows.
     2. Tap the Microsoft account name under Linked account.
     3. Go to Account settings > Sign out and unlink account.
     4. Confirm Unlink.
   • On the PC:
     1. Open Phone Link.
     2. Go to Settings > Devices > Add new device.
     3. Follow the on‑screen steps to pair the Samsung phone again (QR code or code confirmation).
4. Check the PC configuration
   • Confirm the PC is connected to the internet.
   • Make sure Battery saver is Off on the PC.
   • Verify system accounts:
     • Go to Settings > System > Shared experiences.
     • If an account issue is shown, select Fix now and complete the steps.
5. Restart apps if it still fails
   • Close and reopen Phone Link on the PC.
   • If the issue persists after unlinking/re‑linking and checking settings, restart the PC and the phone and try the pairing process again.

If the goal is file transfer specifically over USB (not covered in the provided material), use the Phone Link/Link to Windows wireless connection as above instead.
