It's weird, when I hit repeatedly smooth the back and top of the iphone, I hear the sound. But if I make the same shot in the lower back, the sound does not occur. I feel that something is loose. Also if I make the same in the front of the iphone, I do not esucho no sound or noise. I hope other comments. thanks
Hello, Is it necessary to do step 13 to 18 if I only want to change the battery?
What does can happen if I don’t make all step?
