The instructions are valid for models 2020–2026 and tested on the latest versions of Android (13–15).

1. Which TVs can be configured via an Android smartphone

Not all TVs support control from a smartphone - it all depends on operating system and the year of manufacture of the device. Modern models on platforms Android TV, webOS (LG), Tizen (Samsung) or Google TV guaranteed compatible. But outdated TVs with proprietary firmware (released before 2018) may not have this function.

Here are the main compatibility criteria:

• 📺 Smart TV on Android TV/Google TV: all models Sony Bravia, Xiaomi Mi TV, Philips from 2019 year, Nvidia Shield TV.
• 🔄 TVs with webOS: LG OLED/CX/BX (2020–2026), LG NanoCell (NANO85 series and higher).
• ⚙️ Tizen devices: Samsung QLED (Q60C and newer), Samsung Crystal UHD (CU7000 series and higher).
• ❌ Incompatible models: TVs without Wi-Fi/Bluetooth, released before 2017, as well as budget models with simplified firmware (for example, some TCL or Hisense without Miracast support).

To find out for sure whether your TV supports control from a smartphone, check:

1. Model name on the manufacturer's official website (section "Specifications" → "Control from mobile devices").
2. Presence of a built-in module Wi-Fi Direct or Bluetooth in the TV settings menu.
3. List of supported applications in Google Play (for example, Samsung SmartThings or LG ThinQ).
