For some reason a Motorola Z3 phone won’t work for camera installation. I had a problem yesterday and today, where I wanted to install a Ring outdoor flood light. I had installed a flood light last year, so I thought it would be easy, like the first one. I have had a terrible terrible time. The Android app kept saying that the camera could not connect, over and over again. I was ready to give up, and decided to try installation with my SAMSUNG S2 tablet. I was done in less than five minutes. Don’t know what the problem is/way, but the tablet worked exactly like in the Ring sales videos. Just something for you to think about. If you have a problem, consider trying a different phone or tablet like I did.
