Digitizer replacement without lcd
Can I replace the glass+digitizer without the LCD?
The digitizer is part of the LCD in an s4. Samsung has both the touch and display features combined in the Super AMOLED. If touch is malfunctioning or there are problems with the display image, you must replace the LCD. If it is simply cracked but still functions perfectly, you can do just glass
You can definitely do if LCD is good. Here is a video on how to do it. This is a way of doing it and to me the best if using LOCA glue. If you have any question let me know!
