Remote Control for Sony TV is an application that enables you to control your Sony TV with your phone. 

There are two main modes in this application, the first one is IR and the second one is network. IR works on all phones and tablets that have an infrared port (like Samsung Galaxy S series until S6, HTC One, LG G3/G4/G5, Xiaomi Mi / Redmi / Note, Huawei Mate / Honor and many more).

The purpose of this application is not to replace the original TV remote, but it is handy in emergency situations (original remote is lost, empty batteries etc). 

You can find the compatibility list in the main menu of this application.

To use it, just open the application, select the mode (IR or network) you want to use and start using your TV. It does not require any setup on your device (no WiFi is required).
