iPhone home swipe gesture activated from center in landscape mode with multiple fingers

It Activates more often when 2 or more fingers are detected on the screen, while using the phone while landscape, the home swipe gesture is activated when swiping the center with 2 or more fingers on the screen at a time, at times it may not be activate and at times it may not, I also had this screen repaired around 2 weeks ago, I’ve had this problem since. While the iPhone is vertical, it also detects touch on the bottom right corner, which happens with a case on.
