But!

I believe I downloaded and tried one of these RC apps, for Samsung TV. It found the TV and controlled it very well. A few weeks later I found my 2GB data allowance had been used up - which never happens. I took a look at what had been using it and the app had uploaded 169MB to somewhere in the previous 24hrs, despite me not having used it at all during that period. I deleted it, after leaving that info in a review at the Play Store.
