Samsung s4 screen freezing
Hi.. When I 'wake up' my phone either with the home button or the button on the side, I can swipe the screen & see my home screen but it is 'frozen' When I tap an icon it won't work & if I swipe left or right to get to another home screen it won't work. I have to press the home button again & then it works. It's only just started doing this like yesterday. What have I done & what is the solution. It is also behaving oddly within an app when I press the back button but that would take too long to describe, however that started at the same time so I suspect they are connected.
Can anyone help me - Carol
