@fabif Would it be possible for you to provide a test account so that we can reproduce and identify the problem?
Can't write contactname - it changes to nullnull
Is it possible to write you a private message? I do not want to post login data publicly…
@fabif Did you already contact us? Is the issue still present?
Closing because of missing user response.
This probably a Sony “feature”. I had the same issue using the CardDAV app from the play store.
Phone: Sony Z3 compact with Android 5.0.2
Client: CardDAV 0.4.13
Server: Horde 5.2.6
When you are creating or editing a contact on the phone, you can enter name and some “phonetic” names. Than the name will by ignored causing a “nullnull” name after syncing.
But if you hit the extension button (arrow down symbol at the name fields) you can enter a proper first name and last name. After that syncing worked for me.
I don’t know DAVdroid, but let me know if this works for you.
The Sony phone seems to be confused with all the naming features of carddav.
I can confirm that I have this issue as well on my Sony Z3. bummi2k’s workaround works for me as well, but a real fix would make the app a lot easier to use for Sony users.
I have the same issue, please have a look a this.
Yes, it still there.
My Sony Z3 is fully updated.
If I try to add ad Contacto to CardDAV / (in Sync with OSX-Server.app 5.2), the names come back with nullnull, I guess after sync.
How can I provide more information for you? Perhaps I could let you on a Z3 remote?
