The home button of my iPad Mini 4 still works, but it's not "clicking" properly anymore. I fear that this might lead to the button not functioning at all anymore in the future; that I will not be able to press it down at all, as if it's completely stuck. Does anyone know how to fix an issue like this? (I've started using the virtual button option ('AssistiveTouch') available under 'Accessibility' in order to use the physical home button less.) Thanks!
