The vivo y55s 5.2 inch hd display has a sufficiently high pixel density so jaggedness around icons and text is not very visible color reproduction is fairly good , and we did not have any major issues with viewing angles or sunloght legibillty . The y55s comes with a screen protector already affixed , which is good since this phone dos not have reinforce glass.
Tere are no led either but you can use the rear led flash to alert you to incomming calls messages and reminders the when the screen is off.
