after switching from a samsung s3 to a samsung s7 i lost the pix associated with my contacts. how do i recover them?
If they were associated with your Facebook then it will not happen. You will need to find a 3rd party app that can do it. Facebook removed the feature a few updates ago.
Exactly. A good third party option that is free is called Sync.Me
Sync.ME – Caller ID & Block - Android Apps on Google Play
