my iphone 4g randomly shows vertical lines running across the screen. sometimes its okay but sometimes the lines show up. i still can access apps and receive calls with the screen in that condition. what might be the problem and how can i fix it?
low quality LCD. replace and you will be fine. jessa
Was the screen changed? Agreed it can be a low quality screen or if dropped you have damaged the lcd
Reconnect the LCD screen connector. If it still occurs, it is a hardware problem. You’d better to replace a new LCD screen with digitizer.
