G_raj_dabhi_dryd , via OnePlus 6T , Jan 24, 2022 : When phone used in cold weather (Below 0°C), the one-half to 2/3rd portion of the phone gets dim and starts flickering. After providing heat, it returns back to normal bt it is difficult to use it outside during cold weather. In my personal opinion, don't use OnePlus in cold weather countries such as Canada, US and European countries. I am not at all satisfied with your product. Do suggest a possible wayout or solution for the same.
