I am seeing the exact same issue on s4. It started happening after the OTA update from AT&T

Screencapture requires root permission for most devices. You may need to root your s4 again after OTA.

I have Root Permissions and it still does not work. Other apps that require Root are working.

I have the same issue. I posted in this thread. I linked to it to try and let the Airdroid staff know that there is more than one thread on this issue.

I have root my phone and it is the same problem (even with the last update)
Finaly I have found an alternative for the moment: Mobizen.
