I am running an 820 with a 32Gb Class 4 memory card. I have been having the issues with music duplicating and then not playing properly. Now I am having an issue with recording video/pictures.

When I record a video on my phone. It can not be played back. I get the error "Sorry, we can't play this file on your phone."

Clearly, seeing as I recorded it on the phone, it is a video format that the 820 can play. It seems to be an issue with the SD card. After filming, the video thumb nail appears on the camera roll, and it opens it so it fills the screen. But when I try to share the video, it crashes and returns to the font page. If I click play. It says it can not play.

Photos are a little different in that I can view the photo. But when I try to share the video, it will not allow me. It also has an error saying it can not upload it to sky drive.

I have tried reformatting the memory card but this did not fix the issue.

I love Nokia and have done for many years. However, a number of trivial issues are starting to get VERY annoying. Can anyone suggest a diagnosis followed by a remedy?
