I have a S21 Ultra. I tried to plug the cable to computer.  But computer not recognize the phone. Also the phone doesn't have any notification for connected. Can anyone help? Thanks.

Make sure the plug you are using is made for data transfer and not just for charging

[coolguy94579]

Yes, it is for data transfer. Plug into another S21, works. But not mind.

Try using another cable. If the problem persists it might be your port in the phone

Thanks. I used couple other cables, same.

If you have a uBreakiFix store near you or Best buy you could have them take a look

Assuming that it is a Windows computer, try installing these drivers.  Some computers need these and others don't.  It's worth a shot.

I got it working by going into developer option and turn on the debugging usb. The computer recognized the phone. I haven't try your option yet. If I run into more problem, I will try that.
