my s4 dropped and there's no crack on the front screen but i can see like broken parts in the enternal lcd but the touch is working and the screen is black, what is it? And how can i fix it without paying alot?
You could try to fix it yourself, but that's not always a good idea. Really not much you can do about it besides take it to a professional, unless you're confident enough to take a stab at it.
Broken screens are quiet expensive when you let a technician fix it. They would even say that you better buy a new phone than to repair it. But I think you can order a new screen and try to fix it yourself. You just need some screws for it.
