    • Hi Janeth,
      If your S4 still works normally, you can only replace the front glass lens. You can find it at our website etradesupply.com by searching “Samsung Galaxy S4 glass lens”. But it’s very difficult to only replace the glass lens. Special tools and skills are required for replacement. Please do not hesitate to contact us at service@etradesupply.com if you need any further support.

  23. Hi there! I have Uk samsung S4 GT-I9505. My question is that only my front screen is cracked. The lcd is fine so its only the front glass. How can I replace it?Thank you

  24. I have a Samsung Galaxy S4 I337 from AT&T that received a cracked faceplate but the LCD had no cracks to it so everything was still working (touch screen, etc.) However a few months ago it received some water damage. After a while of drying out it had been working ok. Occasionally it had issues charging and periodical problems with the “home” button but that was it. I was about to replace the faceplate and charging port, when suddenly it went from working to now a black screen with little green dots pixilated on the rightside of the screen. It will not show signs of start up reboot or the home page apps. But yet I can hear my alert tones to text massages and emails. Could you tell me what has happened and if there’s anything that can be done or do I need to get a new LCD screen now as well*
