After install & upgraded july security patch update,I have discovered a serious touch screen issue. While phone is lying on flat surface, if I want to pull down the drop dawn quick setting menu by dragging my finger down ward from upper most portion of the screen...it some time works and some time did not. But while I took it in my hand then trying this ...it works as usual. Please share if any one has been facing this probem and tell how to solve it.....
