With this app "Remote Control for Sony TV" you can use your smartphone to control your Sony TV.  
You can choose between network (WiFi / WiFi Direct / LAN) IP control or infrared (IR) control.

★ Infrared (IR) control
Works on phones and tablets with built-in IR blaster (infrared port) such as Samsung Galaxy S series until S6, HTC ONE, LG G3/G4/G5,  Xiaomi Mi / Redmi / Note, Huawei Mate / Honor and many more. 
No setup required. No WiFi required.  It's ready to use (no need for pairing with the TV).
- Tested on Samsung Galaxy series (S4 / S5 / S6 and Note phones and tablets excluding Galaxy S7 & S8 which do not have IR hardware) running on original Android 4.4+ firmware (not CM/LineageOS).
- Also works on some older Samsung devices running on Android 4.1 - 4.2.2
- Please note that you must point your phone’s IR blaster directly at the TV. Usual working range is 4-10ft (1-3 meters, max ~5 meters).
- With some phones in power saving mode or with almost empty battery the IR blaster might not work or range is less then 5ft (2 meters).

★ Network IP control (WiFi / WiFi Direct / LAN).
 - Make sure the Sony TV that you want to use is turned [On].
 - Make sure your mobile device and TV are connected to the same local/home network.
 - When registering/pairing a Bravia TV, make sure that "Remote Device" / "Renderer" in the settings of  TV is set to [On].
- If you have refused the registering/pairing confirmation message on your TV, then you can change your selection later in TV's settings (usually it's located at HOME / Settings -> Network -> Home Network Setup -> Remote Device -> Remote Device List).

 - If the TV was not found, then it is also possible to enter the TV's IP address manually. To find out you TV IP address go to TV [ Settings ] / [ Network ].
