Review on 55" Samsung TV QE55Q87TAU 2020 QLED, HDR, black silver by Yusri Awin ᠌

Six months ago I bought QE55Q87TAU and during the operation I found several glitches that definitely need to be fixed: 1. automatic brightness control works against logic - when there are credits on a black background, the brightness goes down, and when something bright happens in the movie, the brightness goes up. I understand that the light sensor may not be in this device, but the logic can be implemented normally without it. 2. When you turn on screen repeat from an iPad or iPhone, the multi view mode is turned on first. At the same time, on the left side of the screen there is a DISCONNECTED TV via cable (that is, just white noise), and on the right side the screen of my device is shown. Why do I need this choice? Is it really impossible to predetermine it if the TV cable is disconnected? 3. Since the default brightness settings are very high and hurt the eyes, I lowered the brightness. But after each disconnection / connection of an iPhone or iPad using the "screen repeat" function, the settings go astray and a wonderful TV illuminates not only the entire room, but also part of the apartment. If you start to enter the brightness adjustment menu, the TV remembers on the way that there was a different setting and reduces the brightness. And so every time. 4. After I turn off the "screen repeat" function on the iPad or iPhone, the TV first turns off for a few seconds, and then turns on the cable TV mode again (or rather white noise), but my cable is disconnected. What is this for?
