Can I only change digitizer and not the LCD? My screen top layer is broken, the digitizer and lcd are fine, I don’t think there’s any way to change the top glass without changing digitizer and touch screen.
You can cgange just the glass but this is not easy. In fact if you have never done this repaor before you are probably better off replacing the lcd. You can try to replace the glass but you will probably end up causing damage to the lcd therefore you you might have to get a new lcd after the glass replacement.
