touchscreen – How to stop split screen permanently from occuring

Multi gestures on my infinix hot 4 minimises and goes to recent apps screen or launch split screen automatically. Even when I type very fast, it goes to recent apps. This functions don’t allow me to use my phone for editing, playing games and writing. Whenever more than one finger moves on the phone, BOOM! split screen or Recent apps. It’s frustrating enough that I haven’t found solution online for close to a month. Even here, I read through similar questions (from guys who explained better than I do) and the question is either answered wrongly or systematically abandoned.
