Tvisted works well with with the majority of 2014 and 2015 Samsung TVs with the Tizen operating system. Esp. with the 2015 platform Samsung not all TVs feature the remote control API. For the 2015 platform the minimum is a J5500 TV. There are many J5200 TVs in the homes which will not work (Samsung wants you to spend more money if you want a remote control API).
2014: H4500, H5500 and above (except H6003/H6103/H6153/H6201/H6203).
2015: J5500 and above (except J6203 – use our other app) and the J4500 model.
