Hello
I'm missing the above mentioned button/controls on the time lapse screen. I have this problem in every combination of Nikon D300/700/800 with Samsung Galaxy S3/ Sony Experia Tablet using USB cable or the WLAN solution. Is there a software bug or did I made something wrong? Software is on the latest level.
Regards
Andreas

There is no shutter button in the LRTimelapse screen, because the shutter will be triggered from externally.
There is no aperture control, because it's not a good idea to change aperture while shooting timelapse.
Both intentional.
