I ordered a replacement for the speaker of my Samsung Galaxy S4 mini. I make it clear that it is the speaker at the bottom of the phone, next to the loading dock of the latter, ie the handsfree speaker and listen to music and videos. His change is fairly quick, you only have a very small Phillips screwdriver, a very fine blade to unclip the speakerphone. No son to reconnect it reclipse the new dates back screws and voila.
