Many guys played with their phones and dropped them by mistake. Oh, my God, the phone is broken! Just pick it up and the screen shattered and there is a line there. The phone still turns on and everything works except the screen is destroyed.

Well, I need to say that it is still lucky. The Phone LCD is still good. It is not so costy to change the LCDs. The phones like Samsung S3, S4, S5, Note 3, Note 4, Note 5 or even newer version will be easier to replace the front glass. So do iPhone 5, 5s, 6,6s,6 Plus, 6s plus. The screen is still on and you can see the broken glass. The repair center will use a LCD seperator to repair it.

What shall I do if I am trying to turn on the phone and I am sure of the virbration of start? Sorry to tell you, the LCD is broken. And you have to repair the LCD+Touch. All phones would be done similar.
