Few days back we reported on the Call ending issue in Nokia Lumia 710. Nokia has now responded to the issue in the support discussions and its working on a fix to solve it.
Here is the response from Nokia on the issue,
Nokia is continuing to analyze this software issue and is close to a fix.Â The fix will be made available via Zune as soon as possible.Â It is difficult to say when.Â One other important fact about this issue is that the phone modem is responding to the call disconnect signal from the touch display, the call is taken down as it should.Â The issue is that the user interface displays the call disconnect button but is should not.Â Consequently consumer are not being excessively billed for a call that seems to be staying up.
