I recently changed my samsung galaxy s4 display after being getting shattered screen But that lcd was a duplicate one yesterday i again dropped it from about 2 feet high and now the screen is black with full of white horizontal lines should i replace the screen or is there any fix i can do it by my self Thanks…….

scariavinod.7 this “dropped it from about 2 feet high” leads me to believe that you have a broken display. Of course, always check to make sure that all cables are still connected, ultimately it does sound like you need a new display. Use this guide to get is accomplished.
