Fix My Speaker is the kind of tool that can save your phone many times if you have it at hand. If the speaker suddenly loses its sound or makes a crackling sound, there's nothing to worry about at first — just run this tool once and see. It plays a kind of sound that shakes out the water or dust that has accumulated inside. Sometimes it works right away, and sometimes it takes a few tries to fix it. There's no hassle of going to the store, no expense, and you can try it yourself — a simple solution in the Bengali style of "try it yourself first."
