Debian and Android phone [SOLVED]

[uthappam]

My Debian 9 PC communicated well over a USB cable with my Samsung Z3 phone, which ran on the not popular Tizen operating system. However, I have not been able to get a Nokia 2.1 (Android Go) phone, bought yesterday, to speak to my computer. This makes things difficult as I must look for numbers and e-mail addresses elsewhere. When the phone is connected to the computer it appears in two places, one labelled "Android" and the other "CDROM". The first is empty and the second has directories which are unreadable.

what does dmesg show when you plug in the usb?

[CwF]

Check on the phone how it presents through usb. That 'cdrom' is a emulated cd drive that would likely have some utilities and maybe a pdf, and apparently an unrecognized file system. I had a 'mtk' phone that did that, the setting was on the phone to set appear as mass storage device, that cdrom, as camera and some other options, etc.

Here we are, milomak.

Code: Select all

dmesg: read kernel buffer failed: Operation not permitted

Thank you, CwF. I shall look in the phone for these settings.

dmesg: read kernel buffer failed: Operation not permitted

Thank you, CwF. I shall look in the phone for these settings.

i would have expected the dmesg output to have some /dev/ type of output

maybe try something like dmesg | grep -B 5 -A 5 /dev

[uthappam]

dmesg | grep -B 5 -A 5 /dev gave what dmesg had given earlier. When I ran it with sudo, it gave a long output -- in which did not contain anything about my phone.

Perhaps you need the gnokii deb package, or try gammu.

Thank you, Trinidad. I shall try gnokii -- but gammu (and wammu) do't work with Android.

I use gmtp to access files from my Android phone, you would need to set the phone connection to mtp and I have noticed it sometimes takes quite some time to connect but once connected the transfer rate is good.

[uthappam]

Trinidad, it turned out that gnokii doesn't support my Nokia.

Thank you, Dai_trying; although I have a suspicion that I have tried it already.

EDIT The download was quick and no setting up was needed. Now I can transfer files in both directions -- which is what I wanted.

Was that with gmtp? and if you could mark the topic as solved (edit title of first post) others can find it easier.

[uthappam]

Thank you for reminding me.

oh yes. android moved to mtp. gmtp doesn't seem to be the package that is needed

I looked through your post but did not understand anything. That does not trouble me, though, because I have what I needed.
