I have a sjcam 4000 wifi with 2" lcd display for 3 weeks, and here is my suggestions: 1. Polish menu - bad translation word "sharpness" (in polish menu is kontrast - this contrast, but sharpness is OSTROŚĆ) 2. When I connect the cam to the TV using hdmi cable and turn off the OSD in menu I still see some the characters, It would be nice if there was a 3 steps: show menu, little menu, off (off i mean there is no characters, no icon or something else) 3. When viewing photos or videos on the actioncam i think there is invert between the previous and the next file. The top key navigates to the previous file and lower key to the next one. I think it would be better to reverse. 4. In pc cam mode the camera only works in 720p / 30fps - Is there a way to using cam in 1080p mode? I will be grateful if You would have released new firmware considering my suggestions.
