Android 5.0 “updating contact list” error After updating my android 5.0 (lollipop) phone (Samsung Note 3 N9005) my contact list couldn't open. When I want to open my contacts there was always a process like "updating contact list" and I couldn't open my contacts. Also my Whatsapp contacts were always refreshing when I open whatsapp and click my contacts and it takes long time.
I resolved the problem like below:


Go Settings->General->Cloud->Sync Settings
Tap to "Sync Contacts"
Then go back Settings->General->Application Manager->ALL section
Select "Contacts" then Clear Data and Clear Cache.
Select "Contacts Storage" then Clear Data and Clear Cache (All contacts removed).
Go Settings->General->Cloud->Sync Settings
Tap to "Sync Contacts" to bring your contacts again.
