Hi guy! I also experienced the screen freeze and ghost touch on my pocophone f1 when I bought it. It's so annoying when scrolling to your favourite social media especially when playing games. I've tried searching in the internet for this past days but no one solve it. They say it was a bug on miui 10.2.2 update. They say it will be fix for this upcoming February update. But I found a temporary solution for all pocophone f1 user. Hope this fix ur problem too.
1. Go to Settings
2. Battery and performance
4. Turn off Non-interactive mode ( I think it cause our device to freeze or make ghost touch)
After this I didn't experience any screen freeze and ghost touch anymore.
Pls follow me and like
