I have been unsuccessful uploading my phonebook contacts from my Samsung Galaxy to my online account. The Samsung app indicates "successful completion". When I look at my contacts online, there are zero contacts. What steps should I follow to troubleshoot?
The best advise I have for you on this is to save all of your contacts to google as Google Contacts if you want something that will automatically back up your contacts real time as in right when you add it to your phone, and if you want it to add ALL contacts and to add them accurately.
If you do not want to add your contacts automatically, immediately, and accurately, then Backup Assistant is a good choice for this. I have never been able to get BA to work accurately or consistently since it came out many years ago
