After updating Firefox OS, some people are no longer able to open the call log. Trying to open it results in a progress message that gets stuck at some point (for example 10%) and never finishes.
We are currently working on this. We'll update this article when the issue has been fixed. At that time, your carrier may still have to provide an update to you in order to fix the problem on your device.
