What is the crowd's opinion of YI Action - YI Action Camera?

From 3.5 billion comments

There is an english app, and it is perfectly normal for the files to be split. The file size is a limitation of the file system I think.

Here's the app: https://play.google.com/store/apps/details?id=com.xiaomi.xy.sportscamera&hl=en

You have to use their app to stream. This means that you will have to leave a phone by the camera at all times.

This is the app you need to use.

If you want to leave your house and still watch it this means you need another phone, as you have to leave one at home by your printer, and I assume you always bring your phone with you.
