This issue was reported several times, but still not resolved yet. I read all messages/thread which somehow related to this topic either in Samsung's developers site or in StackOverflow
Let me again describe whole problem just in few words:
Developers used to get list of SMS conversations through simple query like:
Uri.parse("content://mms-sms/conversations/");
Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null);
or something like this. Key point here's URI address: content://mms-sms/conversations
Everyone knows that it's unofficial and one's doing it on his own risk - see proof link here
But, critical point here's a simple fact this code doesn't work properly only in Samsung Galaxy S3 and some models of Galaxy Tab 2. It produces NullPointerException
with stacktrace:
java.lang.NullPointerException
at android.os.Parcel.readException(Parcel.java:1431)
at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:188)

at android.content.ContentProviderProxy.query(ContentProviderNative.java:366)
at android.content.ContentResolver.query(ContentResolver.java:372)
at android.content.ContentResolver.query(ContentResolver.java:315)
In all other devices of the rest of the World/Universe it works well! Strange, huh?
I know answers like: hey dude, it's your problem, since presence/correctness of aforementioned URI doesn't guaranteed, nevertheless, does someone has more productive idea?
I have already posted question to Samsung's developers through their forum.
In the end I've figured how to overcome aforementioned issue (I am not sure that it's bug, but anyway it looks like a bug).
List of conversations can be retrieved through this query:
Uri.parse("content://mms-sms/conversations?simple=true");
Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null);
Keypoint here's URI content://mms-sms/conversations?simple=true
