Ok everyone i dont know why this is but it does work foranyone whos sceen just turned black on day ! I have done this on Galaxy S5 Galaxy 6 Galaxy 7 Galaxy 8 Note 5 Note 6 Note 7 and Note 8 they all After Time screens will go black on them and this is only a temporary fix if you take a small torch and heat up the front of the screen with them evenly so that it is warm to the touch not hot remove your battery twice but sometimes only once and push the power on each time you will get a screen come back on your phone it stays on for a while but then I'll go black again I don't know the reason why this works I just know that it does work on all of them
