hi guys anione experiencing what i do?? What actually is happening is that i believe when we lock the iphone, the screen actually powers off. However for my case, all the surounding pixels are turn off but i experience this short burst of like black line not reallie pixel black line but some weird line on the screen. It really short before the extire screen really turn fully off. Went to singtel today to let them know about my problem but the service center guys insist that its a normal thing for lcd and i should not worry. But am still really doubtful about what they said. Is it a LCD fault or is it my noobness in determining a mistake??
