It's hard to explain but after moving SMS/MMS messages from Xperia Z to Xperia X with Sony Companion app i have a problem with 2 contacts. I can wrote and send but the messages from contact A and B are in the same line.
of course i tried everything delete both contacts, delete all the messages, even starts with the phone from begining without sending the messages. i even changes the message app from Sony for Android Message. nothing change, i have still the same line for both contacts.
And it happens anly for this 2.
Anyone has saw something like this?
