I don't know why but after not checking my phone for almost an hour, I pressed the home button and a fuzzy multi-coloured line image popped up. I tried taking the battery out, resetting it but my screen has just remained black/not in function except for occasionally when the fuzzy coloured lines appear when I press the home or power button. It's strange cause I can hear the phone and even see myself get notifications with the blue dot. Would be highly appreciated if anyone could help. Thanks
