Lost contacts / numbers since Update to 10.3.1 Z10
Hello,
I already saw some posts on similar issues but none that seemed to be the same as mine, Im new here so I hope this is not a double post or in a wrong forum... So heres my problem:
I recently updated to 10.3.1 on my Z10 and ever since I have been missing contacts and numbers. I first noticed it in Whatsapp, there were some contacts that only showed a number as if they were unknown contacts.
Some of them I looked up on "Contacts" and the names are still there but the numbers are missing.
Then I went into Whatsapp to link the numbers with the existing contacts but it doesnt work, they wont link.
I tried restarting, hard reset, battery pull and waiting until putting it back but nothing seems to help. Same seems to be happening with my sisters Z10!
Anybody with same issue or even an explanation/ solution?
