(This technique possibly works for other models as well, but you need to understand it and adapt it for your use case; it is copy-paste for Poco F1 only) Disclaimer: my code makes the “long swipe” gesture unavailable, as I was not using it, but with patience you can come up with a better patch that may retain that functionality as well.
