Sometimes when I am on a phone call (normal or facebook/WhatsApp call) the cursor dances around right along the top of the screen, left to right only and very irratically. I have turned on "show taps" in developer options so I can see it happening, it unfortunately can mean it touches on my notification bar and ends up activating airplane mode or turning off data, turning my flashlight on, etc. Any fixes or reasons for this? Cheers
