Snap chat video? Android to iphone?

So I can send a snap chat video but when she received it it's just a 9 second black screen. I'm sending the video from my Lg connect 4g Android to iPhone 5. Why is the iPhone only seeing a black screen and not my video? I have reinstalled the app and same problem

You can try Android to iPhone Transfer. It can transfer photos and videos between Android devices and iPhone. It is very convenient to use.
