Hi all, here I am sharing with you my personal experiance of our SAMSUNG 4k UHD TV. When we construct a new home, my father bought a new samsung tv from NESTO HYPERMARKET, AJMAN, UAE. Its only 2 years now that we are using it . We only swith on the tv for maximum 1 hour per day . Eventhough now its sound effecf is too low. We cant hear any thing clearly . This is only my personal experiance sharing with you
