I tried it on 5 different phones and it only worked on 2. On some old phones and some new ones, but it seemed random which phones it worked on. I was lucky with the old Samsung, but not with the newer one. No luck with Motorola. One iPhone worked, the other didn't. I've tried updates and searched for the app they recommend but had no luck there either. I'm going back and looking for another option. The remote control is needed, but not this one.
