Having lines show up on a cell phone display might be the result of stuck pixels. Stuck pixels are typically vertical lines that show up in white, green, red or blue pixels. The vertical lines also tend to move, flash or strobe. Stuck pixels can be a result of a phone's age, extreme temperatures or damage. There are ways to remove lines that show up on a cell phone display.
Take your phone to a repair shop. Many repair shop services specialize in repairing lines that show up on cell phones. Alternatively, you can also take your phone back to the place where you purchased to see if it is still under warranty and can be replaced free of charge. Typically, carriers will replace defective phones as long as it is still under warranty.
Replace your screen if you've dropped your phone and the lines are a result of damage. Go online and do a search for your mobile phone's model and replacement kit. Follow the directions enclosed in the kit.
