My Samsung Galaxy S3 just deletes some of my contacts on a regular basis. Any ideas on how to stop this and or recover those deleted contacts?
Are these newly added contacts? If you are adding new contacts and adding them as "phone" contacts and not "google" contacts, and you have syncing on, it may be syncing your google contacts to your phone, and deleting the ones that aren't google contacts. This happened to me a couple of times.
