I purchased a camera from 70mai, which turned out to be one of their Chinese versions. It worked perfectly until they said they were updating their app. I followed their instructions and deleted the old app and installed the new one. After that it never worked properly again or connected to my phone at all, so it is impossible for me to change the settings, view the footage (except on a laptop) or check the cameras view/angle. I have sent 70mai 21 emails to try to get help, but they say they can not as it's a Chinese camera and I live in the UK! They refused to provide the Chinese app and say the online reseller should help, not the support team from the company that makes it and sent me the email telling me to change app! Basically I followed the instructions they emailed me to change the app, after that it became as useful as a chocolate teapot! I now use it as a paperweight.
