Xiaomi Yi connection issue with some Androids

I have recently bought a Xiaomi Yi action camera. I think it's the best price/quality camera you can buy, but... I had some issues trying to connect to it.

I'm going to describe an easy way to get it connected:

-Delete the saved camera WiFi connection. I don't know if it's obligatory.
-Try to connect with the official app, as usual.
-If you can't connect to the camera, disable the network mobile data on your smartphone.
-Then, try to connect again. It must connect now.

I hope it can help you.
