Blocked History not working after Marshmallow upgrade in Lenovo K3 note I recently upgraded my Android system in 'Lenovo K3 Note' to Marshmallow.
Now, I can't see Blocked History in the Contacts.
I could see the notification that some calls are blocked, but I can't see the Block History page.
Whenever I try to access this page, it redirects to the previous page.
Could you please help me fix this issue?

Any leads would be helpful.
I was able  to resolve this issue.

I followed these two links and now I can see the blocked history without having to lose the Call logs, blocked list etc :


Lenovo K3 Note: Blocked History not opening after Android 6.0 update
How to Backup and Restore Call Logs on your Android Phone


Summarizing the steps below from the above links:


Take back up of  contacts and call logs:


Used app SMS Backup &amp; Restore to create a backup of my call logs and message logs. (Got to know about the steps from my second link)
Created Contacts backup (Using Export option in Contacts app)
Created Blocked Contacts backup (using Export black-n-white list option in Contacts (Call / Messages Blocking section)

Go to Settings &rarr; Apps &rarr; All apps &rarr;Contact Manager &rarr; Storage &rarr; Clear Data and Clear Cache.


After this, I was able to see the Blocked History.
Though, I didn't need to import back my Call logs/ Contacts, but yes, I had to import Blocked Contacts. But, that's it and now I'm good.. :)

Hope this helps others who face this issue.. :)
