Wireless transmission of sound or TV control using a smartphone Samsung via Bluetooth - a convenient solution for watching movies, listening to music or using your phone as a remote control. However, not all users know that the Bluetooth connection between an Android device and TV has nuances: from protocol support to model restrictions. In this article, we will look at how to properly connect a phone and a TV wirelessly, what settings will be required, and what to do if the connection is not established.

It is important to understand: Bluetooth between a smartphone and a TV is most often used for transmission audio (for example, to listen to TV through headphones connected to the phone) or to control the TV how remote control. Full screen broadcast (mirroring) on Bluetooth is impossible - for this you need Wi-Fi Direct, Miracast or Google Cast. If your goal is to duplicate the screen, go to the section about alternative connection methods.

We tested the instructions on phones Samsung Galaxy S23 Ultra, Galaxy A54 and televisions Samsung QLED QN90C, Crystal UHD CU7000 (2023–2026). The interface may differ slightly on other models, but the principle remains the same. If you have a TV of another brand (LG, Sony, Xiaomi), check the support Bluetooth in its characteristics - not all manufacturers implement this function in the same way.
