I have got TLC TV 6 years old it is Linux OS.

I am thinking to use it as Smart TV by attaching Android TV Box (HDMI cabel) ,,,,,I tried to read about it but I am confused with below :

1- Can a spare phone like Samsung S10 do the same job as Android TV box in watching Netflix Stan, Disney in 4K or higher quality ?

2- If I have to buy Android TV Box ,,,,can you help me to recommend 3 of them ?
