I'm using DAVdroid to sync Posteo-Server and Samsung Galaxy Note 3 neo (Android 4.4.2).
When fetching a contact from the server DAVdroid adds 2 blanks at the end of the street-field and 1 blank at the beginning of the city-field. I just noticed this today, I'm not quite sure, but I think this happens since my update to DAVdroid 1.3.
Please provide steps to reproduce (so that we can reproduce the problem), debug info and what you exactly receive and what should be received.
Thanks for your email.
The problem has been fixed in vcard4android. The fix will be contained in the next DAVdroid release.
