You don't say what model you had previously, but at least some later
ones (I have the Google Nexus model) use Android 4.x, which does not
support direct access as a mass storage device. According to Google,
this because the phone's "SD Card" is just a region of main memory and
it would be dangerous to allow unmediated access to it.

IOW you need to use MTP or similar. I've had success using Nautilus,
which detects the phone and can mount it via a userland library
(presumably libMTP but I haven't checked). I also installed an FTP
server on the phone; there are several available.
