My "Sony HDR CX900" is a wonderful camera, I've been using it for more than 3 years. But there is some things that I hope can be improve. Analyzing the PlayMemories app, I realize that it is very limited, compared to others used by companies, like Nikon, Canon, even some other third party apps... For instance, I can not connect my Sony CX900 camcorder to the app via USB cable for live viewing while recording; I think the connection would be more stable, (Like DJIGo apps). Also, I would like to be able to record in the Smart Phone cache, the images recorded by the camera. Finally, it would be very helpful to be able to control the Focus and the ISO. The pictures in the "Play Store App", shows those functions, but mine doesn't. I hope the next Firmware Update on the app and on the camera, can achieve those features. I hope to hear from Sony as soon as possible. Thanks!
