Does this use internet data?
I wouldn't think it does, but I noticed looking back over my internet usage from yesterday, it shows I used 5GB of data. I have an allowance of 80GB/month, so it is not much issue, but I could see it being one if I use this function quite often.
I'm using a Samsung Galaxy S4 and last night I played the movie The Hobbit(blu ray 1080p rip 4GB file size). I had the file saved on my SD Card on my phone previously. The file was not downloaded using my internet connection. It was obtained from another source a day earlier, saved on my phone and played to my TV using xbox one.
Any insight would be great.
