Phonejoy Controller - Anyone experience lag?

I recently got my phonejoy analog controller, and i was very happy from the get go, it was easy to setup and seemed to work although i notice when hooking my phone up to my tv while using the controller, i notice quite a bit of lag to the point where it was difficult to play any of the games that i have. i don't have the issue when i'm using just the phone&controller, and not the tv. has anyone had a similar issue?

i'm thinking it is either the distance (i'm sitting about 5-10 feet away), or the connection through the mhl cable i am using.
