Android USB Transfer Stops When the Screen Locks: Windows 11

Before going to bed, I connected my phone to my PC to transfer all my vacation photos, expecting the process to be finished by morning. When I woke up, I found that the progress bar was stuck exactly where I had left it; Windows showed an error, and some files had even become corrupted. Android USB transfer stops when the screen locks – a very common issue in India, especially for users of Redmi, Realme, Samsung, or OnePlus phones who try to move large batches of photos or videos to a PC. In reality, there isn’t just one reason for this; there could be several, and each requires a different fix. In this guide, we will address each of these causes one by one.

First, let’s understand – why does this problem occur?

In reality, this issue can stem from one of four distinct reasons. Identifying the specific cause is essential to applying the right fix:

Cable or port quality
Transferring large files using a low-quality or damaged cable is inherently unreliable; a locked screen only makes the connection even more unstable.

Android USB mode changes when the screen locks
When you unlock your phone, connect it via USB, and select “File Transfer (MTP)” mode, some Android phones automatically switch the USB mode to “Charging only” as soon as the screen locks. This is a security feature – files should not be accessible while the phone is locked.

Windows USB Selective Suspend
Windows 11 includes a power-saving feature that “suspends” idle USB devices. If the data flow slows down momentarily during a transfer, Windows may suspend the USB connection.

Phone display/sleep timer
On some Android versions, the USB connection is briefly interrupted when the phone screen turns off – this has been observed particularly in MIUI (Xiaomi), ColorOS (Realme/OPPO), and Samsung OneUI.

First, diagnose the issue – where is the problem originating from?

Test 1: Connect your phone, start a file transfer, and lock the screen. If the transfer stops immediately, it is an issue with the USB mode or an Android setting.

Test 2: Start a file transfer; do not lock the screen manually – simply leave it inactive for a while. If it stops after a few minutes, it is an issue with the “USB Selective Suspend” setting in Windows.

Test 3: Try using a different cable and a different USB port. If this resolves the issue, it was a problem with the quality of the cable or the port.

Test 4: If the transfer completes successfully while the screen remains ON, it confirms that the screen lock is specifically the cause of the problem.

Fix 1 – Keep the screen ON during the transfer (the easiest fix)

This is a temporary but immediate solution. Use it as a workaround until other fixes can be applied.

Increase the display timeout on Android:

1. Go to Settings → Display → Screen timeout
2. Set it to 30 minutes or the maximum available value
3. Change it back to the normal setting once the transfer is complete

Enable “Stay awake” from Developer Options:

1. Go to Settings → About Phone and tap on “Build Number” 7 times (this will unlock Developer Options).
2. Open Settings → Developer Options.
3. Enable the “Stay awake” or “Keep screen on while charging” option.
4. When this option is active, the screen will never lock while the phone is connected to a charger or a USB cable.

⚠️ Note: Enabling this option ensures that the phone reverts to its normal sleep behavior as soon as it is disconnected from USB. There is little concern regarding battery drain, as the device is also being charged by the PC/laptop.

Fix 2 – Keep Android USB mode set to MTP even after the screen is locked

Android USB file transfers often stop when the screen is locked – this is the most common reason. As soon as the phone screen locks, the USB mode switches to “Charging only.”

Set the default USB configuration:

1. Open Developer Options (unlock it using the steps provided above).
2. Find “Default USB configuration.”
3. Set it to “File Transfer (MTP).”
4. Now, the phone will automatically enter MTP mode every time it is connected, even when the screen is locked.

For Samsung phones:

• Settings → Developer Options → Default USB configuration → MTP

For Xiaomi/MIUI phones:

• Settings → Additional Settings → Developer Options → Default USB configuration → File Transfer

For Realme/ColorOS phones:

• Settings → Additional Settings → Developer Options → Default USB configuration → MTP (Media Transfer Protocol)

Fix 3 – Disable USB Selective Suspend in Windows 11

Windows 11 automatically suspends USB devices when in power-saving mode. This is the setting that cuts off the USB connection when the screen becomes inactive.

Method A – Via Power Plan:

1. Win + R → powercfg.cpl → Enter
2. Click “Change plan settings” next to Current power plan
3. Click “Change advanced power settings”
4. USB Settings → Find the USB selective suspend setting
5. Set it to “Disabled”
6. Apply → OK

Method B – From Device Manager:

1. Win + X → Device Manager
2. Expand “Universal Serial Bus controllers”
3. Right-click on each “USB Root Hub” entry → Properties
4. Go to the “Power Management” tab
5. Uncheck the box labeled “Allow the computer to turn off this device to save power”
6. Repeat this for every “USB Root Hub”

Fix 4 – Set Phone as Trusted Device in Windows 11

Windows 11 sometimes requires the phone to be re-authenticated when the screen is locked. Way to avoid it:

Install MTP Driver Correctly:

1. Connect the phone via USB in MTP mode.
2. Open Device Manager.
3. The phone will appear under the “Portable Devices” section.
4. Right-click → Update driver → Browse my computer → Let me pick.
5. Select “MTP USB Device”.
6. Install it and restart your computer.

Check the Windows Media Player Network Sharing settings:
Sometimes, the Windows Media Player MTP driver causes conflicts. Go to Services (Win + R → services.msc) and set the “Windows Media Player Network Sharing Service” to “Automatic.”

Fix 5 – Exclude USB from the phone’s battery optimization

Android’s aggressive battery optimization feature sometimes kills background USB processes.

Samsung OneUI:

1. Settings → Battery → Background usage limits
2. See USB/MTP related processes in “Never sleeping apps”
3. Settings → Apps → View all apps → Give “Unrestricted” battery access to USB-related services

MIUI (Xiaomi/Redmi):

1. Settings → Apps → Manage apps → Three dots → Special app access
2. Give “No restrictions” to system apps in the Battery saver section

Stock Android (Pixel, Android One):

1. Settings → Apps → Special app access → Battery optimization
2. Set MTP-related services to “Don’t optimize” in the “All apps” view

This setting resolves the issue where Android USB file transfer stops when the screen is locked, specifically in cases where background processes are being terminated.

Fix 6 – Check the quality of your cables and ports

It may seem tedious, but it shouldn’t be ignored.

How to identify a good-quality cable:

• Use a USB 3.0 cable (with a blue connector) – it is 10x faster than USB 2.0 and provides a more stable connection.
• Charging-only cables do not work for data transfer – check the cable’s specifications.
• Cheap, third-party cables often fail during large data transfers.

Check the port:

• Connect the phone to a USB port on the PC’s back panel, not the front panel – front ports are often less reliable.
• If you are using a USB hub, try connecting directly to a port on the motherboard instead.
• Use a USB 3.0 port (blue), not a 2.0 port (black/white).

Quick test:

• Try on another PC with the same cable
• If it works fine there – there is a problem with Windows settings
• If it fails there too – replace the cable

Wireless alternatives are more reliable for large transfers.

If this problem keeps recurring and the aforementioned fixes do not work, then a wireless transfer could be a permanent – and, in fact, better – solution.

FAQs – About USB Transfer Stops When the Screen Locks

One final point – apply the right fix once, and your transfers will be completely hassle-free

Large file transfers – such as vacation videos, phone backups, or project files – often need to run overnight, and it’s incredibly frustrating when they get interrupted. Among the solutions mentioned above, enabling “Stay awake” in Developer Options and disabling “USB Selective Suspend” in Windows settings will resolve the issue in 90% of cases. Alternatively, if a USB connection doesn’t feel reliable, wireless tools like LocalSend offer a better solution; they keep transfers going uninterrupted, whether the screen is locked or unlocked. Since Android USB file transfers tend to stop when the screen locks, fixing this issue properly once and for all means you won’t have to keep searching for workarounds every single time.
