Note 10+ oneui 4 creating overheating causing display flickering

[Sohel_bd]

Greatings to all.

I am using my decvice for last 3 months. On February 11, I updated it to one ui 4.0. Due to mobile data and gps usuage, I noticed that it becomes more hotter than ui 3.0.

When ever it becomes hotter/overheating, displays become flickering just like it loses its saturation. Below 10% of brightness, display becomes okay (fine). 

I think overheating causes display flickering. Should I wait for next update? Or any other means to avoid overheating problem?

I usually find faded display when the temperature is above 34 degree Celsius. Whenever I use mobile data, phone becomes hotter quickly. 

Such kind of issues were not found at 3.0 ui. 

What can I do right now? Wait for next update or security update? Or angrily throw it to bin? I am fully dissatisfied with Samsung service. Or any other way to get back to one ui 3.0?

I even can't wipe cache partition by volume and power button.
