Android app for kami and Yi resetting when trying to view video or live full screen.

Anytime and every time I try to view full screen it goes back to the start up screen and tries to refresh app.
I am extremely frustrated with this app.
Also whenever I record a video from the SD card it will not record audio… The speaker button is gray with a line thru it and will not activate. Sometimes it will take me 10 times to re-record it to get the audio to finally activate.
I am having a very difficult time trying to get video recordings with audio to the police and whenever I try to view full screen to review my recordings for them… Having over 30 cameras, starting to loose my patience with your apps.

Impossible to view live feed without it constantly refreshing the app… Both kami and Yi on Android. Please turn off the refresh.
