Quick Share shows two nearby computers with similar names. Before sending the document, open Quick Share on the intended receiving computer and check the name it advertises. A familiar-looking entry is not enough to identify the destination.
Check the app and receiving setting
Google's instructions cover its Quick Share app for Windows and direct Samsung PC owners to Samsung's app. Check the current device and regional requirements in the source below. Google lists Android 6 or later and 64-bit Windows 10 or later, with Windows 11 or later required on ARM PCs. App compatibility is separate from the operating system's support lifecycle.
For Google's Windows app, turn on Bluetooth, connect the devices to the same network and check receiving visibility. Your devices is intended for devices using the same Google Account; Contacts and Everyone have different audiences. Choose only the visibility needed for this exchange. Run the app normally, not as administrator.
Verify a small transfer first
Send a harmless image with a distinctive filename. If a PIN appears, compare it on both devices before accepting. Transfers between your own devices signed into the same Google Account can be accepted automatically, so a missing approval prompt is not necessarily a fault.
On the receiving Windows computer, Google's app saves files in the Quick Share folder inside Downloads. Open the received copy and compare its content, not just its filename, especially if an older version exists. Then restore your preferred visibility. Finding a device, completing a transfer and receiving the intended file are separate checks.
