My Samsung tv 2019 model #4K/QLED/QE65Q67 is very buggy, since I bought, sudden turn off, sudden microphone turn on on listening mode sometimes even when TV off. And, worst lately Samsung ambient can't do any of smart features it has like uploading photos or custom living room frame.
I bought 2 years ago already, since I bought I called support many times, they visited me at my house 3 times, last time they change the TV motherboard.
Nothing helped, I am very disappointed and very unsatisfied with this product.
