Do we need to unmount a cell phone before unplugging it from USB?

I copied these entries I found in KSystemlog after unplugging my cellphone from USB…

Perhaps I have a lazy habit from windows that I need to change under Linux? Opening Dolphin after reconnecting the phone shows the Internal and SD Storage paths under the phone… but there is no option to right-click and unmount that I can see… so, what should I have done to properly disconnect the cell?

Oh, and while the Disks and Devices plasmoid prompted me with what to do when I first connected the phone (I chose mount)… there is no option there afterwards to disconnect/unmount the cell either.

When you are using MTP for file transfer then you can find the commands to unmount the cell phone folders here:

Why not link directly to the Arch Wiki?

To answer the actual question as to the need to unmount: no, you do not need to unmount.
For an explanation, why this is ok for mtp access, see:

Thank You Wollie and freggle.doe for your replies!

I think freggle.doe’s information directly answers my question… and suggests that I can just simply ignore these KSystemlog the events… considering them normal/expected behavior.

And Wollie’s link has some great details/instructions on making the phone mountable/unmountable if I ever find that is necessary… which doesn’t sound like it is at the moment.

This of course assumes I am understanding/interpreting everything you’ve both shared correctly :wink:
