How do you transfer files from phone to computer ? Transfert de fichiers tél-ordi par USB: comment faire?

Message en français à la fin

Hello,
I am a newbie.
My Samsung Galaxy A52s was delivered a week ago with iodé 5.8 installed.
I am making my first steps.
Is it possible to transfer files (photos…) from my phone to a computer ?
I’ve connected the phone with a compatible and verified USB-cable to two different computers running Kubuntu 20.04 and Kubuntu 24.04.1.
The phone is detected but I cannot access the files on the phone.
The parameters are set on “transfer files” (or equivalent… I’m using french iodé).
Thanks for the advice !

Bonjour,
Je viens d’arriver.
Mon téléphone Samsung A52s a été livré la semaine dernière avec iodé 5.8 installé.
Je découvre.
Est-ce possible de copier depuis le téléphone vers un ordi ? (Photos,…)
J’ai connecté le Samsung par câble USB à 2 ordis avec Kubuntu 20.04 et Kubuntu 24.04.1.
Le câble USB fonctionne: les ordis signalent que le périphérique est détecté mais je ne peux pas accéder au contenu du téléphone…
J’ai bien “transfert de données” activé dans les paramètres.
Merci d’avance pour les conseils !

I use Totalcommander for Android with the sftp Plugin and connect via sftp to my linux box. The SSH Server is running on the Linux box

I use SimpleSSHD from F-Droid, which enables me to just use a bookmark in my computer’s file manager to display folders from the phone (login credentials required) over wifi (at home).

Other than that: USB drive or USB cable.

Thanks laneb for your advice.
What is a Linux box ?

Thanks Taurus-II, I don’t have wifi at home.
When you write USB cable, what do you mean ?
I think it is what I tried… But I failed.

Precisely this:

Normally, the following should work: Search for the phrase “Use USB for” in your phone settings, and select “File Transfer.”
I’m not sure why it’s not working for you, though.

Slang (argot) meaning “a computer running Linux.”
(Because a computer looks like a box.)

Thanks Taurus-II,
I’ve learnt what a “Linux box” means, great !
I have noticed that I have encountered several issues:
1-Kubuntu 20.04 does not support MTP (an apparently well known bug) and I’ve found a turnaround to be able to make it work on this page: https://doc.ubuntu-fr.org/mtp

sudo killall kiod5

and then

mtp-detect

was all I needed to connect my computer and phone…

2-For the other Linux box on Kubuntu 24.04.1, I have rebooted everything and it worked like a charm.

Something I noticed (and I think it is weird): every time I connect my phone to a computer, I must reset the parameters to “file transfer”…
I would have liked it to be always set as a default setting but it seems like I will have to do this thing over and over…

At the end of the day, I can copy my files from my phone to my PC so I consider this topic solved.
