my poco is the same if the screen has moisture on it, it goes crazy with the ghost touches i sat and watched the notification area going up and down until i dried it properlyI think the poco F1 screen is very sensitive to water. In my phone, just the sweat of my hands activates ghost touch, which makes typing annoying or the navigation bar buttons get triggered. To fix it I have to wash the screen and dry it with a towel, drying with my clothes doesn't work. Maybe I just need to buy a case and hopefully that fixes it.
