Synchronizing Samsung phone with Xiaomi TV via Bluetooth: the full guide

Connecting a Samsung smartphone to a Xiaomi TV via Bluetooth opens up new possibilities for viewing content, managing media, and even using the phone as a remote. However, many users face difficulties: connection is interrupted, sound is delayed, devices do not see each other at all. In this article, we will discuss all the stages of synchronization — from preparing devices to solving typical problems — taking into account the features of the MIUI and One UI firmware.

It’s important to understand that Xiaomi and Samsung use different ecosystems, and their interaction via Bluetooth is not always perfect. For example, Xiaomi TVs based on Android TV (Mi TV 4S/5X, Redmi Smart TV models) support A2DP (for sound) and AVRCP (for control), but may not recognize some features of Samsung Galaxy smartphones due to proprietary protocols. We tested the connection on the Galaxy S23 Ultra, Galaxy A54 and Xiaomi Mi TV Q2 2023 – everything worked, but with nuance.

If you need to not only transmit audio, but also duplicate the screen, Bluetooth is not going to work — it will require Miracast or Google Cast (via Wi-Fi). This article will focus exclusively on wireless audio synchronization and media management. Ready to figure it out? Let's start with the preparation of devices.

1. Verification of device compatibility
