Hi,I need help too. I have a Sony Xperia C4 Dual and sometimes, when I'm trying to make a video full-screen or it starts an add while I'm doing something , the screen is blocking. In the video case,it's getting green and it's turning off and then on. On the add case,the image is blocking and stays there while the sound is still working,and after the add ends the phone is turning off and then on again. I think it has problems whit the screen,but I don't know what to do whit it like this! Please help!
