Syncing contacts with Facebook and contact visualization in dialer

Question

Hi, 
I have spent a lot of time trying to sync and consolidate my contacts from Google and Facebook. I did have a couple of issues however and I am looking for advise. 
1) Contact photo from Facebook are very low res and blurry.
     - Xperia with Facebook account has the both contact & calrendar sync checked, and sync has completed, but no photos are synched.
     - Facebook account has retreived the photo from Facebook, but it is extremely low-res and very blurry.
2) Is there a way - after linking a google contact to a Facebook one to quickly copy or merge (selected) Facebook contact details (like photo, birthday, phone number, email or address) into the Google contact.
3) Once I select a phone number as primary is there a way to see in the dialer (using T9 search) only the default phone number. Currenlty I may see a mobile phone from Facebook, another mobile phone from Google, and maybe a couple of other phones, and everytime I search for this contact directly in the dialer I need to remember and choose which number to dial.
So far the only resolution seems to be to switch back to exDialer, which would be a shame since this is my only complaint from the Xperia dialer.
4) Is there a way to backup the link between the google and facebook contacts? Is there a way to backup which phone number, email or address is default? Both of these are not preserved in google contacts, so everytime I reset or change phones I need to start all over.
I am looking for your advice and best practices and thank you in advance!!

Answer 1

OK, so after spending some time for research here are my findings:
1) Synching contact pics from Facebook to Android contacts: Facebook and Xperia with Facebook accounts do not work. As a workaround I have used Contacts+ application from the Google Play store, it works as expected.
2) Merging Facebook contact info (pic, phone number, email, birthday) to google contacts - have not found a way to automate or, best, semi-automate this just yet. Easiest manual option - view a contact, long press the phone/email/birthday, then edit the contact and paste. Will not work for the contact pic though.
3) Show a single record for the contact in the dialer and remember the default phone - Xperia dialer cannot do this, Contacts+ and exDialer can be used as a replacement though.
4) Backup the Google to Facebook link  &  the default selection for phone number, email, address in case of a hard reset or transfer between phones - no complete solution found yet, need to review more contact backup apps. At least one can edit the names of the google contacts so that they are spelled as in Facebook to make a future matches quick & more fluent.
