Hello recently I bought this TV .
It was working properly when I bought and the quality of sound system was also quite good.
It was also surpoting android , but somehow some issues created with it's sound system, it stopped working after few months. Even it was not supporting any of their speakers.
The vision was also became worst.
HD channels were became very downpoor.
When I called their customer service they provided me a mechanic to fix my TV. But even after repairing it was not working perfectly.
I think this just because of its poor quality.
Not satisfied from this product, it is cheap than any other brands but also it is worst than any other TV.
