How to control a TV from a Xiaomi Redmi 9T phone: 5 ways + problem solving

Why Redmi 9T is the perfect fit for TV control

Xiaomi Redmi 9T, with its 4/64GB of memory, Snapdragon 662 processor and IR transmitter on the top, is one of the most versatile devices for remote control.

This is especially valuable for older TVs without smart platforms or with unstable Internet.
