Peel requires an IR blaster to shoot the remote commands through your phone to your appliances. 

Unfortunately, Samsung didn't include IR blaster in S7, S7 Edge and hence making the phone incompatible to our remote app.

However, you can still use our Peel app to control your Smart TV, if it has in-built WiFi. 

Ensure that your Smart TV is connected to your WiFi network same as your phone. 

Rest assured, Peel app takes care of detecting the device in the network and provide the option to setup and control. 

As an alternative, you can get a Pronto which is an IR blaster device, where you can control your TV, STB, AC, Streaming player, BluRay, DVD, AVR et al. Check this link below to know more about Pronto:
