@Rock Liu What was the improvement on this update? I just took it. 1. Please fix the auto screen rotate when the app is open. It doesn't work correctly and in the home screen when you tilt it the app now completely shuts down. Also need the video and pic screens to auto rotate instead of having to hit button to correct manually. 2. Add the ability to view only front cam or rear cam on phone screen. Plus both as you have now but with the option to switch views for each into the smaller or larger window according to user preferences. 3. I think you improved the function of the dvr to start recording automatically when you go into the menu to view videos or change settings. Previously when I went in, you had to manually restart the recordings where now it does on own. Good improvement on that.
