I am facing an issue called “Semaphore timeout”. My pc detects my phone. I start transferring files from phone to pc. However, after exactly 30 minutes, the error msg comes up and file transfer stopped.

I had a software called spacedesk which, allowed me to use my phone/tablet as an external display.
As soon as I uninstalled that, everything started working fine.

Please check if you have any software such as what I was using, and try again. Phone itself is most probably fine.

I manage to find out the solution

Under Developer options, choose DEFAULT USB configuration. You may change to File Transfer options

So, I wanted to transfer some data from my phone (1) to my laptop, but the laptop just doesn’t see it. I tried other phones with the same cable and USB port, and they appeared in the computer explorer. My phone is charging when connected, but I can’t do anything else.
