I have been having issues like this recently and a quick search here found this thread. My situation seems quite similar and it is just so frustrating now and just feels so messed up, I am getting issues over adding people into my list that were previously there, but have recently come onto Skype or my Facebook friends etc, and it has created nothing but issues trying to get it right. It has created new contacts, altered the name of a current contact but added new details in, not added or merged or linked, not picked up as a new Facebook contact and just generally been difficult to follow who is who when actually looking at it.
For example I have one contact that has 8 links as follows:
*Name* *Surname* – Outlook
*Name* mobile – Outlook
*Name* mobile – Outlook
*Name* mobile – Outlook
*Name* mobile – gmail
*Name* *Surname* – Facebook (beta) (app local) (Facebook (Beta))
+44********** - Skype
*Name* *Surname* – Skype
I have noted it more since putting my default messaging to Skype, but I can’t say for sure it is down to that, as I started to see the issues when I had a new number SMS me and I couldn’t save the number as a new contact from Skype, just no option, but from the actual messaging app it was simple, I am using a L640 on standard OS updates by the way.
Does anyone have any ideas on best means of sorting this type of thing, is it best to delete and start afresh?
