My iphone 5s screen has a white line and sometimes the screen also having glitch so can I know what do I need to do?
Either the screen is not plugged in properly or the screen is damaged, usually from being dropped. White vertical lines usually indicates the LCD ribbon flex cable for the screen not plugged in properly. Any other kind of artifacts on the screen would point to a damaged LCD which would require the screen to be replaced. In case you need to replace the screen I have linked where you can buy a replacement screen from iFixit and a guide to replace the screen: iPhone 5s Screen Replacement iPhone 5s Screen
