Ratings and reviews

With a single ELP stereo vision camera I'm getting a single picture out and a second picture which only comes up when you put your finger really close to the ELP camera only when MJPG conversion is set to off. And in that mode the second eye the left eye no matter which one I choose is always a very streaky camera. I think it's a problem with this app. Please fix and score will be raised.

I think there's a new problem with the app because a Verizon visible and TracFone having different owners within the past 5 years. this app works on Motorola phones that use the North American Google Play store but not on phones that use the TracFone software channel. no one is able to get me to change back to Google Play. This mismatch error has to be fixed, because I tried fixing it myself and there's no way a user can by themselves.

Setting up front and rear viewing video cameras on an ODroid based self-built car head unit. After lots of attempts with 'dashcam' apps, which all failed in various ways, this works flawlessly. Best thing is that the app gives all the details and options of the hardware and doesn't treat the user like an idiot. Thanks, great work!
