Fixed this issue on Xperia XA by changing the Display Size. Settings - Display - View - Display Size (changed to max size) Doing this made the status bar bigger and so easier to grab/drag. In addition the bottom buttons are more responsive. I just tried this after reading solutions of use root access to change screen resolution. It worked for me. Maybe with some experimention I could find just the right setting of Display Size but maximum works and I am okay with how the screen looks.
