This service is to replace the broken screen on your Samsung J4 2018, model number J400. It will replace both of the front glass, digitizer, and LCD altogether. So it doesn't matter if you broke the front glass, or the underlying LCD, this service will fix them all.

We normally stock two types of screen: copy screen, and original Samsung screen. Here are the main differences between them:

  • Quality of display. The colour of original screen is more beautiful and vivid. Colour of copy display is not as great as the original one, even though it is the best copy screen available in the market.

  • Thickness of the screen. Original screen is made of OLED or AMOLED, therefore the screen is very thin and will fit into the metal housing perfectly. Copy screen is made of LCD. The screen is about 2mm thicker than original one. Therefore after installation there will be small gaps (very small) between the screen and the metal housing.
